In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

As shown in Figures 1 to 11, according to the first aspect of the present application, the present application provides an endoscope, including a window component 30, a first imaging component 10 and a second imaging component 20, wherein the first imaging component 10 and the second imaging component 20 are detachably connected together, and the window component 30 is connected to the front end of the first imaging component 10 and the second imaging component 20. Through the "modular" thinking mode, the endoscope can be decomposed into three independent components according to the needs of assembly, which simplifies the complexity and makes the various parts of the endoscope easy to disassemble and assemble, and easy to use; at the same time, avoiding limiting the size and placement of the sensor due to the assembly problem of the endoscope, which is beneficial to the manufacture of the endoscope and can effectively reduce the production cost of the endoscope.

Exemplarily, the first imaging assembly 10 includes a first bracket 11, a first sensor 12 having a first photosensitive surface, and a first optical element 13, and the second imaging assembly 20 includes a second bracket 21, a second sensor 22 having a second photosensitive surface, and a second optical element 23, the first sensor 12 and the first optical element 13 are both arranged on the first bracket 11, and the second sensor 22 and the second optical element 23 are both arranged on the second bracket 21. Among them, a mounting hole 311 is arranged on the window component 30, the first bracket 11 and the second bracket 21 are connected to the rear end of the window component 30, the positions of the first optical element 13 and the second optical element 23 correspond to the position of the mounting hole 311, the first photosensitive surface and the second photosensitive surface are arranged opposite to each other, and the axis of the mounting hole is perpendicular to the axis of the first photosensitive surface and the axis of the second photosensitive surface.

Among them, the endoscope includes a front endoscope and a rear endoscope. The front endoscope mainly refers to the first sensor and the second sensor arranged in the insertion tube of the endoscope placed in the patient's body, while the rear endoscope refers to the first sensor and the second sensor arranged on the handle operating part, which does not need to be placed in the patient's body, and the handle operating part and the insertion part are separable. After the inspection, the insertion tube needs to be washed and disinfected under a high temperature and high pressure environment to ensure the safe use of the insertion tube. Therefore, in the front endoscope, the first imaging component 10 and the second imaging component 20 need to be sealed, which also increases the manufacturing process of the endoscope, and the first imaging component 10 and the second imaging component 20 need to be focused and aligned, and then sealed by welding or the like, which further increases the manufacturing process of the endoscope.

In addition, most endoscopes adopt a tubular structure, and in order to avoid irritation or other unpleasant experiences when the endoscope is placed in the patient's body, the outer diameter of the endoscope is as small as possible. Generally, the outer diameter of the endoscope does not exceed 10 mm. With the development trend of endoscopic imaging systems, endoscopic imaging systems have higher and higher requirements for image clarity, gradually developing towards 4K. The clearer the image, the higher the requirements for image quality and resolution. The size of the first imaging component 10 and the second imaging component 20 will also increase accordingly. The maximum outer diameter of the endoscope not only limits the placement form and maximum size of the first imaging component 10 and the second imaging component 20, but also indirectly limits the image resolution and image quality of the first imaging component 10 and the second imaging component 20.

Therefore, the present application not only facilitates the focusing alignment between the first imaging component 10 and the second imaging component 20, but also facilitates the sealing connection between the window component 30 and the first imaging component 10 and the second imaging component 20, by splitting the endoscope into three independent components, namely the window component 30, the first imaging component 10 and the second imaging component 20, so as to ensure that the endoscope can be washed and disinfected under a high temperature and high pressure environment, making the manufacturing process of the endoscope simpler. At the same time, the first photosensitive surface and the second photosensitive surface are arranged opposite to each other, which can be beneficial to the placement of the first sensor and the second sensor, and the first sensor 12 and the second sensor 22 will not be unable to be placed in the first bracket 11 and the second bracket 21 due to the size of the first sensor and the second sensor. The first sensor 12 and the second sensor 22 can be arranged along the length direction of the first bracket 11 and the second bracket 21, and the first photosensitive surface and the second photosensitive surface can obtain the image light reflected or excited by the specific part of the inspection object through the first optical element 13 and the second optical element 23.

In an optional embodiment, the axis of the first photosensitive surface coincides with the axis of the second photosensitive surface, so that the first sensor 12 and the second sensor 22 can be relatively arranged on the first bracket 11 and the second bracket 21, and the positions of the two are the same, which facilitates the focusing alignment between the first sensor 12 and the second sensor 22.

It should be noted that the axis of the first photosensitive surface may also be parallel to the axis of the second photosensitive surface, and this application does not impose any limitation thereto.

In an optional embodiment, the window component 30 includes a window piece 32, which is mounted on the mounting hole 311 and corresponds to the positions of the first optical element 13 and the second optical element 23. The first bracket 11 and the second bracket 21 are connected to the rear end of the window component 30, and the positions of the first optical element 13 and the second optical element 23 correspond to the position of the window piece 32. The window piece 32 can close the far end of the window component 30 to protect the first sensor 12 and the second sensor 22, and the first sensor 12 and the second sensor 22 can observe outward through the window piece 32.

The present application divides the endoscope through a modular design concept, and divides the endoscope into three modular structures: a window component 30, a first imaging component 10, and a second imaging component 20. Not only is the structure and function division clear, but also the complexity and difficulty of assembling the endoscope are reduced; and the three modular structures are first independently installed and then assembled. There is no need to install the first sensor 12 and the second sensor 22 in the insertion tube 50 of the endoscope along the radial direction of the insertion tube 50, which solves the problem that the placement form and maximum size of the first sensor 12 and the second sensor 22 are limited by the maximum outer diameter of the insertion tube 50. The window component 30, the first imaging component 10, and the second imaging component 20 are assembled together, so that the three modular structures can form an effective whole, and there is no need to install the components separately in the insertion tube 50 with a smaller space, which is conducive to the integration of internal components of the endoscope.

In an optional embodiment, as shown in FIGS. 1 to 5 , the window component 30 includes a window seat 31 connected to the first bracket 11 and the second bracket 21 , wherein the first bracket 11 and the second bracket 21 are symmetrically arranged about the central axis of the window seat 31 . In this embodiment, the mounting hole 311 is arranged on the window seat 31, a first accommodating groove 112 is formed on the first bracket 11, and a second accommodating groove 212 is formed on the second bracket 21. The first sensor 12 is accommodated in the first accommodating groove 112, and the second sensor 22 is accommodated in the second accommodating groove 212, and the first sensor 12 and the second sensor 22 are arranged back to back, so that the first sensor 12 can be arranged corresponding to the first optical element 13, for receiving the image transmitted by the first optical element 13 and converting it into an electrical signal for output, and the second sensor 22 is arranged corresponding to the second optical element 23, for receiving the image transmitted by the second optical element 23 and converting it into an electrical signal for output, and a relay component can be arranged on the opposite surface between the first sensor 12 and the second sensor 22, and the relay component can be electrically connected to the signal transmission component of the endoscope, and can output the image signals generated by the first sensor 12 and the second sensor 22 to the image processing component of the endoscope. Through this structure, the miniaturization design of the endoscope can be further realized.

It should be noted that the number of the window piece 32 can be one, and the mounting hole 311 corresponds to a through-hole structure spanning the first receiving groove 112 and the second receiving groove 212, and the mounting hole 311 is installed in the through-hole structure, so that the first sensor 12 and the second sensor 22 can obtain the image light reflected or excited by the specific part of the inspection object through the window piece 32. Alternatively, the number of the window piece 32 and the mounting hole 311 are both two, and the two window pieces 32 are correspondingly installed in the two mounting holes 311, and one of the window pieces 32 corresponds to the position of the first receiving groove 112, and the other window piece 32 corresponds to the position of the second receiving groove 212, so that the first sensor 12 can obtain the image light reflected or excited by the specific part of the inspection object through one of the window pieces 32, and the second sensor 22 can obtain the image light reflected or excited by the specific part of the inspection object through the other window piece 32.

In an optional embodiment, the first imaging component 10 also includes a signal transmission component, which includes a first signal transmission component 14 and a second signal transmission component 24. The first signal transmission component 14 is electrically connected to the first sensor 12, and is used to output the image signal generated by the first sensor 12 to the image processing component of the endoscope; the second signal transmission component 24 is electrically connected to the second sensor 22, and is used to output the image signal generated by the first sensor 12 to the image processing component of the endoscope.

Exemplarily, the endoscope also includes an image processing component, wherein the first sensor 12 is used to convert image light reflected or excited by a specific part of the inspection object acquired by the first sensor 12 into a first electrical signal, and the first electrical signal is transmitted to the image processing component via the first signal transmission component 14 for processing; the second sensor 22 is used to convert image light reflected or excited by a specific part of the inspection object acquired by the second sensor 22 into a second electrical signal, and the second electrical signal is transmitted to the image processing component via the second signal transmission component 24 for processing.

In this embodiment, the second signal transmission component 24 is arranged side by side with the first signal transmission component 14 and extends along the length direction of the first bracket 11 and the second bracket 21. This not only reduces the space occupied by the second signal transmission component 24 and the first signal transmission component 14 on the first bracket 11 and the second bracket 21, but also facilitates the heat dissipation between the first signal transmission component 14 and the second signal transmission component 24, and balances the heat generated by the electronic components on the first signal transmission component 14 and the second signal transmission component 24 due to work to the first signal transmission component 14 and the second signal transmission component 24, and then dissipates the heat to the outside through the first bracket 11 and the second bracket 21.

Among them, the second signal transmission component 24 and the first signal transmission component 14 are arranged side by side, which means that the length direction of the second signal transmission component 24 and the length direction of the first signal transmission component 14 are arranged along the extension direction of the first bracket 11 and the second bracket 21, that is, the side-by-side arrangement direction of the second signal transmission component 24 and the first signal transmission component 14 is the same as the extension direction of the first bracket 11 and the second bracket 21, and in this embodiment, the side-by-side arrangement of the second signal transmission component 24 and the first signal transmission component 14 includes the second signal transmission component 24 and the first signal transmission component 14 being arranged side by side in contact with each other or close to each other. In an optional embodiment, the first signal transmission component 14 includes a first PCB board 141 and a first FPC board 142, the first sensor 12 is arranged on the first PCB board 141, and one end of the first PCB board 141 is connected to the first FPC board 142, which is used to transmit the first electrical signal converted by the first sensor 12 to the image processing component of the endoscope, so that the image processing component can process the first electrical signal obtained from the first sensor 12 and then display it on the display.

In an optional embodiment, the second signal transmission component 24 includes a second PCB board 241 and a second FPC board 242, the second sensor 22 is arranged on the second PCB board 241, and one end of the second PCB board 241 is connected to the second FPC board 242, which is used to transmit the second electrical signal converted by the second sensor 22 to the image processing component of the endoscope, so that the image processing component can process the second electrical signal obtained from the second sensor 22 and then display it on the display.

To ensure the final three-dimensional imaging effect, the first signal transmission component 14 and the second sensor 22 select two sensors of the same model. The two sensors respectively convert their respective acquired images into electrical signals, and transmit the electrical signals to the image processing component through the first signal transmission component 14 and the second signal transmission component 24 respectively.

In an optional embodiment, the first signal transmission component 14 includes a first connector 143, wherein the first PCB board 141 is plugged into the first FPC board 142 through the first connector 143, so that the first electrical signal can be transmitted from the first FPC board 142 to the first PCB board 141, and the image processing component can receive the first electrical signal from the first FPC board 142 through the first PCB board 141.

In an optional embodiment, the second signal transmission component 24 includes a second connector 243, and the second PCB board 241 is plugged into the second FPC board 242 through the second connector 243, so that the second electrical signal can be transmitted from the second FPC board 242 to the second PCB board 241, and the image processing component can receive the second electrical signal from the second FPC board 242 through the second PCB board 241.

After adopting the above technical solution, since the first sensor 12 is accommodated in the first receiving groove 112 and connected to the first PCB board 141 through the first FPC board 142, and the first PCB board 141 has flexibility, it is convenient to adjust the installation position of the first sensor 12 and the first PCB board 141, so that the first sensor 12 can be accommodated in the first receiving groove 112 and set corresponding to the first optical element 13, and the first PCB board 141 can be connected to the image processing component. Similarly, the second sensor 22 is connected to the second PCB board 241 through the second FPC board 242, and the position of the second sensor 22 in the first receiving groove 112 and the position of the second PCB board 241 can also be adjusted by the flexibility of the second FPC board 242, so that the second sensor 22 can be set corresponding to the first optical element 13, and the second PCB board 241 can be connected to the image processing component.

In an optional embodiment, as shown in FIG. 10 , the endoscope includes a sealing tube 40, which is sleeved on the outside of the first bracket 11 and the second bracket 21, and is used to seal the first imaging component 10 and the second imaging component 20 to ensure that the endoscope can be sterilized in a high temperature and high pressure environment.

In an optional embodiment, a hollow cavity is formed in the sealing tube 40, and the hollow cavity has a first inner cavity with a non-circular cross-section, and the first signal transmission component 14 of the first imaging component 10 and the second signal transmission component 24 of the second imaging component 20 are accommodated in the first inner cavity.

With the development trend of endoscopic imaging systems, endoscopic imaging systems have higher and higher requirements for image clarity, gradually developing towards 4K. The clearer the image, the higher the requirements for image quality and resolution. Therefore, the amount of data transmitted is larger, which makes the size required for signal transmission components also increase day by day. However, the diameter of the endoscope is very small, generally 10 mm or less, and it is also very difficult to seal the endoscope. The present application can accommodate a larger first signal transmission component 14 and a second signal transmission component 24 by setting a first inner cavity with a non-circular cross-section, which can not only meet the development needs of the endoscopic imaging system for image clarity, but also solve the difficulty of sealing the endoscope, and will not increase the external size of the endoscope.

Among them, the non-circular cross-section refers to other shapes besides a circle, such as an irregular shape such as an oblate, elliptical, semi-elliptical, quasi-elliptical or polygonal shape, and its main purpose is to enable the first signal transmission component 14 and the second signal transmission component 24 to be accommodated in the first inner cavity.

In an optional embodiment, the sealing tube 40 includes a second sealing tube 40 and a first sealing tube 40 forming a first inner cavity, wherein the second sealing tube 40 is connected between the window component 30 and the first sealing tube 40. By dividing the sealing tube 40 into two parts, namely, the first sealing tube 40 and the second sealing tube 40, and then assembling the first sealing tube 40 and the second sealing tube 40 together, the processing and manufacturing of the sealing tube 40 can be facilitated, and the production cost of the sealing tube 40 can be reduced.

In an optional embodiment, the first sealing tube 40 is provided with a pipe connecting end at one end close to the second sealing tube 40, and the second sealing tube 40 is inserted into the pipe connecting end. In order to ensure the sealing ring between the first sealing tube 40 and the second sealing tube 40, the first sealing tube 40 and the second sealing tube 40 are fixed together by a welding process. The structure is simple and the processing is convenient. At the same time, the sealing between the first sealing tube 40 and the second sealing tube 40 can also be ensured.

In an optional embodiment, the second sealing tube 40 is provided with a connecting groove at one end facing the first sealing tube 40 , and the first sealing tube 40 is inserted into the connecting groove to ensure the sealing between the second sealing tube 40 and the first sealing tube 40 .

In an optional embodiment, as shown in Figures 3 and 11, a first connecting end 312 is provided on the window seat 31, and the outer diameter of the first connecting end 312 is adapted to the inner diameter of the second sealing tube 40, so that the second sealing tube 40 can be inserted into the second sealing tube 40 and then welded and fixed, which plays a positioning role and also ensures the sealing of the sealing tube 40 after being connected to the window seat 31.

Specifically, the first connecting end 312 is provided with a first chamfer on the side facing the sealing tube 40, and the first chamfer is used to guide the sealing tube 40 to be quickly plugged into the first connecting end 312, thereby reducing the problem of positioning and guiding the sealing tube 40 and the window seat 31 during the assembly process, so that the sealing tube 40 can be quickly installed on the window seat 31.

Generally, the sealing tube 40 is a hollow tube made of metal material, which can not only prevent the external high temperature and high pressure from affecting the first imaging component 10 and the second imaging component 20 in the sealing tube 40, but also transfer the heat generated by the first imaging component 10 and the second imaging component 20 in the sealing tube 40 due to work, so that the heat generated by the first imaging component 10 and the second imaging component 20 during work can be quickly transferred to the outer surface of the sealing tube 40 for heat dissipation. At the same time, the sealing tube 40 made of metal material can also withstand the high temperature and high pressure disinfection environment.

In an optional embodiment, the endoscope includes an insertion tube 50, which is arranged on the outside of the window component 30, the first imaging component 10 and the second imaging component 20 to wrap and protect the window component 30, the first imaging component 10 and the second imaging component 20.

In an optional embodiment, the insertion tube 50 is connected to one end of the window component 30. After the window component 30, the first imaging component 10 and the second imaging component 20 are assembled, the insertion tube 50 is fixed to the window component 30 and wrapped around the outside of the first imaging component 10 and the second imaging component 20 to protect the first imaging component 10 and the second imaging component 20.

In an optional embodiment, the insertion tube 50 and the window component 30 are integrally formed. After the first imaging component 10 and the second imaging component 20 are assembled, the integrally formed insertion tube 50 and the window component 30 are fixed to the front end and the outside of the first imaging component 10 and the second imaging component 20.

In an optional embodiment, the endoscope includes a heat dissipation component 60, which is disposed in the insertion tube 50 and is used to transfer the heat generated by the first imaging component 10 and the second imaging component 20 when they are working to the insertion tube 50, and then transfer the heat to the outside air by the insertion tube 50, so as to solve the problem that the endoscope has difficulty in heat dissipation due to its small size. Specifically, the heat dissipation component is used to transfer the heat generated by the first imaging component 12, the second imaging component 22, the first signal transmission component 14, and the second signal transmission component 24 when they are working to the insertion tube.

Exemplarily, as shown in Figures 9 and 10, the heat dissipation component 60 includes a first heat conductor 61, which is arranged between the first signal transmission component 14 and the second signal transmission component 24. The first heat conductor 61 can evenly conduct the local heat of the first signal transmission component 14 and the second signal transmission component 24 to the entire first signal transmission component 14 and the second signal transmission component 24, thereby achieving a uniform heat effect and better conducting away the heat when the first signal transmission component 14 and the second signal transmission component 24 are working.

In an optional embodiment, the heat dissipation component 60 includes a second heat conductor 62, which is arranged between the first signal transmission component 14 and the first bracket 11, and between the second signal transmission component 24 and the second bracket 21. The second heat conductor 62 can conduct the heat on the first signal transmission component 14 and the second signal transmission component 24 to the first bracket 11 and the second bracket 21, and then conduct the heat from the first bracket 11 and the second bracket 21 to the insertion tube 50 and dissipate the heat by the insertion tube 50, so that the first sensor 12 and the second sensor 22 can be quickly cooled to the normal operating temperature, thereby ensuring the image quality of the endoscope.

In an optional embodiment, the heat dissipation assembly 60 includes a third heat conductor 63, which is disposed between the insertion tube 50 and the first bracket 11 and the second bracket 21, and can conduct heat from the first bracket 11 and the second bracket 21 to the insertion tube 50, which then dissipates heat.

Among them, the thermal conductivity of the third heat-conducting member 63 is greater than the thermal conductivity of the second heat-conducting member 62, and the thermal conductivity of the second heat-conducting member 62 is greater than the thermal conductivity of the first heat-conducting member 61, so that the heat on the first bracket 11 and the second bracket 21 can be quickly transferred to the insertion tube 50 for heat dissipation, avoiding the heat on the first bracket 11 and the second bracket 21 from being conducted to the first signal transmission component 14 and the second signal transmission component 24, and the heat on the insertion tube 50 is conducted to the first bracket 11 and the second bracket 21. This is mainly because the heat absorption rate of the third heat-conducting member 63 is much greater than the heat absorption rate of the second heat-conducting member 62, and the heat absorption rate of the second heat-conducting member 62 is greater than the heat absorption rate of the first heat-conducting member 61, thereby forming a unidirectional heat transfer, so as to effectively exert the heat dissipation effect of the combination of the first heat-conducting member 61, the second heat-conducting member 62 and the third heat-conducting member 63.

In addition, the outer wall of the sealing tube 40 can be in contact with the inner wall of the insertion tube 50, and the third heat-conducting member 63 is arranged between the sealing tube 40 and the first bracket 11 and the second bracket 21; or, the inner wall of the sealing tube 40 can also be in contact with the outer wall portion of the first bracket 11 and the second bracket 21, and the third heat-conducting member 63 is arranged between the sealing tube 40 and the insertion tube 50; or, the sealing tube 40 is arranged between the insertion tube 50 and the first bracket 11 and the second bracket 21, and the third heat-conducting member 63 is arranged between the sealing tube 40 and the insertion tube 50, and between the sealing tube 40 and the first bracket 11 and the second bracket 21, or the third heat-conducting member 63 is arranged between the sealing tube 40 and the insertion tube 50, and a fourth heat-conducting member is arranged between the sealing tube 40 and the first bracket 11 and the second bracket 21, and the thermal conductivity of the fourth heat-conducting member is smaller than the thermal conductivity of the third heat-conducting member 63.

After adopting the above technical scheme, since the outer diameter of the endoscope does not exceed 10 mm, if it follows the conventional structure and assembly method, it cannot meet the development trend of the endoscopic imaging system, especially the endoscopic imaging system has higher and higher requirements for image clarity, and there are certain limitations on the sealing and heat dissipation of the endoscope. The present application divides the endoscope into three independent modular structures and then assembles them, which not only solves the difficulties of the endoscope, but also allows the sealing tube 40 to be sleeved on the outside of the first signal transmission component 14 and the second signal transmission component 24 to seal the endoscope. In addition, the heat dissipation component 60 can be filled between the first signal transmission component 14, the second signal transmission component 24, the sealing tube 40 and the insertion tube 50 to solve the problem of heat dissipation difficulties of the endoscope.

As shown in Figures 1 to 10, according to the second aspect of the present application, the present application provides an endoscopic imaging system, including a light source host, a light guide, a camera host and the above-mentioned endoscope, wherein the light source host is connected to the endoscope through the light guide, and the first imaging component 10 and the second imaging component 20 are connected to the camera host through a signal transmission component.
