Description

A surgical imaging system combining endoscope and exoscope

Technical Field

The utility model relates to the field of medical instruments, and in particular to a surgical imaging system combining an endoscope and an exoscope.

Background Art

The endoscopic surgical imaging system currently used in clinical practice is composed of a rod-shaped (hard or soft) lens group connected to an image acquisition processing and display system, and some electronic endoscope image acquisition systems are located at the front end of the rod-shaped structure. It can enter the body cavity or surgical cavity for close observation, magnify the field of view, and provide a clearer picture through image processing. In practical applications, the long rod-shaped endoscope needs to be extended into the deep part for surgery, but it can only collect the field of view in front of the rod-shaped endoscope, and cannot provide images of the rear end of the rod-shaped structure. It cannot observe, operate, and protect the periphery of the endoscope barrel and the rear structure. During the operation, the operation of the endoscope and surgical instruments is likely to cause damage to the structure outside the field of view of the front end of the endoscope, limiting its application in deep structure surgery and inspection.

At present, deep and delicate surgical operations are mainly performed under a surgical microscope, which is large in size and can only be placed outside the body cavity or surgical cavity and provide an external field of view, but cannot enter the body cavity. It is difficult to provide excellent field of view images for deep tissues and peripheral structures of the surgical area, and the existing exoscopic surgical imaging system cannot be used in conjunction with the endoscope system, thereby making it impossible to observe, operate and protect the endoscope barrel itself and the structure behind it.

In summary, the prior art has the following problems: the existing endoscope system can only obtain the field of view in front of the endoscope barrel, and cannot obtain images around and behind the endoscope barrel, which is not convenient for deep structure surgery and inspection.

DETAILED DESCRIPTION

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the utility model is now described.

As shown in FIG1 , an embodiment of the present invention provides a surgical imaging system combining an endoscope and an exoscope.

A surgical imaging system combining endoscope and exoscopic imaging system, comprising:

Housing 1, image acquisition device 2, endoscope 3 and connection component 4;

One end of the connecting component 4 is connected to the housing 1, and the other end of the connecting component 4 is connected to the endoscope 3;

The endoscope 3 includes an endoscope base 31 and a lens barrel 32 which are connected transversely, and the front end of the lens barrel 32 includes a probe; wherein the image acquisition device 2 includes an external mirror lighting device 21 and an external mirror image acquisition device 22 which are arranged outside the housing 1;

The exterior mirror lighting device 21 and the exterior mirror image acquisition device 22, for example, include a camera, which is arranged on the front side of the housing 1 together with the connecting component 4; in the embodiment of the utility model, in order to ensure that the light source of the exterior mirror lighting device 21 can cover the probe position at the front end of the lens barrel 32, and at the same time the exterior mirror image acquisition device 22 can capture a clear image, the brightness of the light source of the exterior mirror lighting device 21 is not less than 200 lumens, and the resolution of the exterior mirror image acquisition device 22, such as the camera, is not less than 360p in digital signal mode or not less than 400 lines in analog signal mode.

The exterior mirror lighting device 21 and the exterior mirror image acquisition device 22 are located behind the lens barrel 32, for example, at an oblique rear, so that the exterior mirror lighting light can be collected without being blocked to capture the image of the periphery of the probe at the front end of the lens barrel 32;

The front end of the lens barrel 32, especially the probe at the front end of the lens barrel 32, is within the illumination range of the exterior mirror lighting device 11, so that the probe at the front end of the lens barrel 32 is illuminated, and the image of the periphery of the probe can be captured by the exterior mirror image acquisition device 22.

In the embodiment of the utility model, an external mirror lighting device 21 and an external mirror image acquisition device 22 are arranged outside the endoscope 3, and both the external mirror lighting device 21 and the external mirror image acquisition device 22 are connected to the front side of the housing 1, and the housing 1 is connected to the endoscope 3 through a connecting component 4, as shown in FIG3, the light source provided by the external mirror lighting device 21, for example, adopts an LED light source; other applicable light sources such as LEDs introduced by optical fibers, halogen lamps; or surgical lamps or other light sources outside the device, etc. In order to achieve better lighting effects and reduce the size and weight of the device, it is preferred to adopt an LED light source. Area A can be covered, and the front end of the lens barrel 32 is within this area, so that the lens barrel 32 itself and the surrounding cavities are also within the area that the light source can illuminate. By selecting a suitable light source to ensure sufficient light intensity and saturation, the exterior mirror lighting device 21 and the exterior mirror image acquisition device 22 are reasonably arranged. For example, the angle between the exterior mirror lighting device 21 and the lens barrel 32 is reasonably set, and a suitable lens is selected to match the light divergence angle θ of the exterior mirror lighting device 21, so that the lens barrel 32 is exposed to sufficient light, thereby ensuring that the exterior mirror image acquisition device 22 obtains a clear image.

In the embodiment of the utility model, the components of the image acquisition device 2 are preferably integrated devices to reduce their volume and weight, so that the size of the housing 1 can smoothly enter the body cavity or surgical cavity. When performing deep and delicate surgery, the embodiment of the utility model can enter the body cavity or surgical cavity, and the external mirror image acquisition device 22 collects clear images of the global field of view of the surgical cavity under the sufficient light source provided by the external mirror lighting device 21. Area B is the illumination radiation range of the front end of the endoscope 3. Through the illumination range of area A and the illumination range of area B, the embodiment of the utility model can achieve the purpose of simultaneously obtaining the image of the front end of the endoscope 3 and the image of the barrel 32 itself, the probe and its surroundings.

Furthermore, the exterior mirror lighting device 21, the exterior mirror image acquisition device 22 and the connecting component 4 are sequentially arranged on the front side of the housing 1 from top to bottom; the outer ends of the exterior mirror lighting device 21 and the outer ends of the exterior mirror image acquisition device 22 do not exceed the connection between the endoscope base 31 and the lens barrel 32.

The exterior mirror lighting device 21, the exterior mirror image acquisition device 22 and the connecting component 4 are sequentially arranged on the housing 1 from top to bottom, and the outer ends of the exterior mirror lighting device 21 and the outer ends of the exterior mirror image acquisition device 22 do not exceed the connection between the endoscope base 31 and the lens barrel 32, so that the light source can more completely cover the entire lens barrel 32, thereby allowing the operator to observe a longer area when operating in the surgical cavity.

Furthermore, a lens is provided at the front end of the external mirror lighting device 21. The external mirror lighting device 21 contains a light source, and the light of the light source is irradiated onto the lens barrel 32 and the surgical cavity around it through the lens at the front end of the external mirror lighting device 21.

Furthermore, an LED light source is provided in the exterior mirror lighting device 21, and the light divergence angle θ of the exterior mirror lighting device 21 is 30°-60°. A lens or a reflective cup is provided on the outer end surface of the exterior mirror lighting device 21, and the light source is diverged by the divergence effect of the lens or the reflective cup, and the light divergence angle θ is 45°-60°, for example, θ is 30°, 45° or 60°, so as to ensure that the light of the exterior mirror lighting device 21 can illuminate the entire lens barrel 32. In order to make the lens barrel 32 closer to the vertical middle position of the A area, even if the lens barrel 32 is in an area with high light saturation and high intensity, so that the exterior mirror image acquisition device 22 can capture a clearer image, the exterior mirror lighting device 21 can be set to illuminate the lens barrel 32 at an angle of 45 degrees to the lens barrel 32.

Furthermore, the vertical spacing between the exterior mirror lighting device 21, the exterior mirror image acquisition device 22 and the connecting component 4 is 1mm-3mm. The larger the vertical spacing between the exterior mirror lighting device 21, the exterior mirror image acquisition device 22 and the connecting component 4, the smaller the illumination area of the exterior mirror lighting device 21 irradiating the lens barrel 32. If the spacing is too large, the light may not cover the entire lens barrel 32, thereby affecting the image acquisition effect of the exterior mirror image acquisition device 22. According to the requirement that the light covers the entire lens barrel 32 and the size requirements of the overall device, the vertical spacing between the exterior mirror lighting device 21, the exterior mirror image acquisition device 22 and the connecting component 4 is controlled to be between 1mm-3mm.

Furthermore, the exterior mirror image acquisition device 22 includes a transversely connected image acquisition module 221 and a global image lens 222. The model and specifications of the global image lens 222 can be selected according to the actual application scenario and needs, and the outer end of the global image lens 222 is vertically flush with the outer end of the exterior mirror lighting device 21. In this way, it can be ensured that the light source will not be blocked because the outer end of the global image lens 222 exceeds the outer end of the exterior mirror lighting device 21, and the rear end of the lens barrel 32 in the image captured by the global camera lens 222 will not have a blind area without light because the outer end of the exterior mirror lighting device 21 exceeds the outer end of the global image lens 222.

Furthermore, the outer end of the global image lens 222 is located above the outer end of the connecting component 4 and the outer end of the endoscope base 31. The global image lens 222 can collect more complete images of the lens barrel 32 itself and the surroundings, without collecting other useless images including the endoscope base 31, eliminating interfering images, and facilitating the operator to view image information.

Furthermore, as shown in FIG2 , the image acquisition device 2 further includes an endoscopic image acquisition device 23 and a power supply and data transmission module 24; the power supply and data transmission module 24 is electrically connected to the exterior mirror image acquisition device 22, the exterior mirror lighting device 21 and the endoscopic image acquisition device 23 respectively. The power supply and data transmission module 24 supplies power to the endoscopic image acquisition device 23, the exterior mirror image acquisition device 22 and the exterior mirror lighting device 21, and transmits the images acquired by the endoscopic image acquisition device 23 and the exterior mirror image acquisition device 22 to the image processing module at the rear (i.e., other devices of the endoscope system other than the present utility model), and transmits the images to the display after the image processing is completed. The operator observes the situation of the cavity in the surgical area and the front end of the lens barrel 32 through the display, so as to clearly grasp the overall and local fields of view, providing convenience for the surgical operation. The power supply in the embodiment of the utility model can be one power supply that supplies power to the endoscopic image acquisition device 23, the exterior mirror image acquisition device 22 and the exterior mirror lighting device 21 at the same time, or it can be divided into two independent power supplies, one for supplying power to the endoscopic image acquisition device 23, and the other for supplying power to the exterior mirror image acquisition device 22 and the exterior mirror lighting device 21. Using one power supply can save the cost of the overall system and reduce the size. Using two independent power supplies will only affect one operation when one of the power supplies fails, and will not affect the entire system.

Furthermore, the exterior mirror lighting device 21 and the exterior mirror image acquisition device 22 are both cylindrical. The cylindrical exterior mirror lighting device 21 and the exterior mirror image acquisition device 22 are easy to install, and since both the exterior mirror lighting device 21 and the exterior mirror image acquisition device 22 need to enter the body, the cylindrical shape is more rounded without edges and corners, and is more suitable for the internal environment.

Furthermore, the power supply and data transmission module 24 are wirelessly connected, including a battery and a wireless transmission device. In the embodiment of the utility model, the battery and the wireless transmission device are installed to reduce the line connection and facilitate the operation of the operator.

The embodiment of the utility model adds an external mirror lighting device 21 and an external mirror image acquisition device 22 outside the endoscope 3, so that the system includes two sets of image acquisition devices, namely, the external mirror image acquisition device 22 and the endoscope image acquisition device 23. The image acquisition module 221 in the external mirror image acquisition device 22 is connected to the global image lens 222, and the endoscope image acquisition device 23 is connected to the endoscope adapter lens at the rear end of the endoscope base 31, so that the external mirror image acquisition device 22 and the endoscope image acquisition device 23 can respectively obtain corresponding images. After the external mirror image acquisition device 22 and the endoscope image acquisition device 23 acquire the corresponding images, they can be transmitted to the rear image processing module through a signal line or a wireless signal system. After receiving the signal, the rear image processing module transmits the processed image to the display after processing. The display simultaneously displays the local image acquired by the endoscope image acquisition device 23 and the global field of view image acquired by the external mirror image acquisition device.

In the embodiment of the utility model, the light source in the endoscope 3 and the external mirror lighting device 21 can be provided by a single light source, which is divided into two paths, one path is connected to the light source interface of the endoscope 3 by a light guide fiber, and the other path is provided to the global image lens 222 through the lens at the front end of the external mirror lighting device 21. Two independent light sources are used, that is, a light source is set in the light source interface of the endoscope 3 and the external mirror lighting device 21 respectively. The power supply in the embodiment of the utility model can be a power supply that simultaneously supplies power to the endoscope image acquisition device 23, the external mirror image acquisition device 22 and the external mirror lighting device 21, or it can be divided into two independent power supplies, one for the endoscope image acquisition device 23, and the other for the external mirror image acquisition device 22 and the external mirror lighting device 21. The power supply and data transmission module 24 can be connected to the rear device by wired means such as cables or electronic circuits, or data can be wirelessly transmitted by means of batteries plus wireless transmission devices.

When the embodiment of the utility model is used for work, the operator extends the lens barrel 32 into the patient's body, starts the external mirror lighting device 21 and the external mirror image acquisition device 22 outside the body, provides sufficient light source to the lens barrel 32, and collects the image around it at the same time. The endoscope 3 collects the image at the front end of the lens barrel 32, and transmits the two images to the display at the rear. The operator can simultaneously obtain the image data around and in front of the lens barrel 32. The external mirror lighting device 21 in the embodiment of the utility model is used to provide light source to the lens barrel 32 inside the body, so that the light can be irradiated into the body more concentratedly. However, when the light in the operating room is used, the intensity of the light cannot completely cover the front end of the lens barrel 32, and due to the equipment obstruction of the surgical environment and the gradual weakening of the light intensity, the light in the operating room cannot conveniently and effectively provide sufficient light source to the lens barrel inside the body. If independent lighting equipment and image acquisition equipment such as independent flashlights and cameras are used, it is necessary to increase special personnel to hold the corresponding equipment to cooperate with the operator to provide light source and collect images into the patient's body, which not only increases the labor cost, but also easily causes coordination errors between personnel. The operation is inconvenient. In addition, the illumination path of the handheld independent light source cannot be completely consistent with the travel path of the lens barrel 32. When encountering obstacles or turns, the handheld independent light source cannot provide effective illumination for the lens barrel 32. It is difficult to ensure that the illumination direction is consistent with the requirements during the operation and it may block the operation. The embodiment of the utility model connects the exterior mirror lighting device 21 and the exterior mirror image acquisition device 22 with the endoscope 3. Only one operator is required to operate the instrument to provide a light source around the lens barrel 32 in the body. The operation is simple and convenient, and the illumination path of the light source can be kept consistent with the travel path of the lens barrel 32, so that the illumination range can always cover the front end of the lens barrel 32.

When the endoscopic image acquisition device 22 acquires images, the endoscopic lighting device 21 provides a light source to photograph the barrel 32 of the endoscope 3, so that the front end of the barrel 32 can be within the illumination range of the endoscopic lighting device 21, and the positions of the endoscopic lighting device 21 and the endoscopic image acquisition device 22 are reasonably set, and a reasonable light source is selected to ensure that the barrel 32 can be exposed to sufficient light, so that the acquired image is clearer. Under the illumination of the endoscopic lighting device 21, the endoscopic image acquisition device 22 acquires images of the barrel 32 itself and the surrounding surgical cavity, while the endoscope 3 acquires images of the front end of the barrel 32, so that the operator can simultaneously obtain images of the surgical cavity, that is, the global field of view, and the local field of view in front of the endoscope 3 during the operation, thereby facilitating the operator's observation and operation during the operation, and also increasing the application scope of the endoscope system, which can be applied to more surgical scenes.

The above description is only an illustrative embodiment of the utility model and is not intended to limit the scope of the utility model. The components of the utility model can be combined with each other without conflict, and any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
