The duodenoscope lens end 1 and the duodenoscope provided by the present invention will be described below with reference to FIGS. 1-10 .

In order to solve the problem that the camera part 3 of the existing duodenoscope is integrated with the head end part 1, the angle of view cannot be switched quickly, and the camera part 3 occupies too much space, resulting in the limitation of the maximum size of the instrument channel 7, which is not conducive to the passage of instruments The problem. The present invention provides a duodenal lens end 1, comprising: a mounting base 2, on which an instrument channel 7 is opened; an imaging unit 3, movable on the mounting base 2, to have a first working state and In the second working state, in the first working state, the viewing angle direction of the imaging unit 3 faces the front view direction, and in the second working state, the viewing angle direction of the imaging unit 3 faces the side viewing direction; When using the mirror, firstly, the viewing angle direction of the imaging unit 3 needs to face the front view direction (the mounting base 2 is generally cylindrical, that is, the viewing angle direction extends approximately toward the axial direction of the mounting base 2, and the angular deviation from the axis of the mounting base 2 does not exceed ± 30°, most preferably parallel to the axis of the mounting seat 2), so that the outer diameter of the head end 1 is the smallest, which is convenient for entering and exiting the mirror; after the head end is placed in the target area, it is necessary to switch the viewing direction of the camera 3, Convert the viewing direction to the wall facing the intestinal tract (i.e., the side viewing direction, the viewing direction is inclined or perpendicular to the axis of the mounting seat 2, and the angle deviation from the orthogonal direction of the axis of the mounting seat 2 is no more than ±30°, most preferably with The positive direction of the axis of the mounting seat 2 is 105°), so that the pathological changes of the intestinal tract can be observed conveniently. In addition, the head end part also has a driving part 4 , which is arranged on the mounting base 2 and is used to drive the camera part 3 to move.

In the traditional technology, in order to meet the viewing angle requirement of the camera unit 3 directly or side-viewing, two groups of different camera devices are generally set up, each with a different viewing angle. The cost will increase the difficulty of layout. In the present invention, the switching of the viewing angle can be achieved through the movement of one camera part 3, which reduces the cost; in addition, the movement of the camera part 3 makes full use of the space at the head end, which can release more head end space for the instrument channel 7. Setting is conducive to designing a larger instrument channel 7, which facilitates the passage of instruments during inspection.

Specifically, the present invention provides an arrangement method for the instrument channel 7 , one of which is that the opening 8 of the instrument channel 7 is provided at the side wall of the mounting base 2 , and the imaging unit 3 is movably provided on the upper end surface of the mounting base 2 . Since general instruments operate on the wall of the patient's intestinal tract, when the opening 8 of the instrument passage 7 is arranged on the side wall of the mounting seat 2, on the one hand the side wall of the mounting seat 2 has no interference from other parts, and a larger diameter can be set. on the other hand, the imaging unit 3 arranged on the upper end surface of the mounting seat 2 will have a larger installation space and activity space, and a larger imaging unit 3 can be set to meet the requirements of good imaging needs.

The second is that the opening 8 of the instrument channel 7 is arranged on the upper end surface of the mounting base 2, and the camera section 3 is movable on the upper end surface of the mounting seat 2; when the camera section 3 is in the first working state, the camera section 3 is covered on the instrument channel 7 At the opening 8 of the opening 8, when the imaging unit 3 is in the second working state, the imaging unit 3 is set away from the instrument channel 7 to fully reveal the instrument channel 7. It should be noted that, in the conventional technology, the imaging unit 3 arranged on the upper end surface of the mounting base 2, since a part of the usable area of the mounting base 2 will be occupied by the imaging unit 3, the usable area left for the instrument channel 7 will be reduced. The maximum size of the instrument channel 7 is limited. In the present invention, by setting the imaging unit 3 to be movable, the imaging unit 3 can movably cover or open the instrument channel 7, so that the instrument channel 7 originally limited in size can be expanded, and the size of the imaging unit 3 can be further increased. Get better image effects.

Specifically, a camera 9 is provided on the upper surface of the imaging unit 3 , and the camera 9 is used for imaging. Of course, the imaging unit 3 also includes an illumination device 10 and a moisture device 11 . The imaging section 3 has a first side wall 12 and a second side wall 13 that are oppositely arranged in the longitudinal direction, and the imaging section 3 has a movable stroke of rotation; it can be understood that the imaging section 3 relies on flipping to switch the imaging angle. In the first working state, the first side wall 12 and the second side wall 13 are both perpendicular to the mounting base 2, and in the second working state, the first side wall 12 is close to the mounting base 2 so that the viewing angle of the camera 9 faces sideways extend in the direction of view. It should be noted that, if the imaging unit 3 is a cuboid or a cube, that is, the first side wall 12 and the second side wall 13 are both planes, the first side wall 12 or the second side wall 13 can be selected as the flip surface, but if As in the semi-cylindrical imaging section 3 provided in this embodiment, the first side wall 12 is a plane, and the second side wall 13 is an arc surface, and the imaging section 3 is better with the first side wall 12 as a turning surface, so that the imaging section 3's movement is more stable. In this embodiment, in order to improve the space utilization rate of the head end, the imaging unit 3 is arranged near the edge of the head end, in this case, only a side wall away from the edge of the head end can be selected as the turning surface; if the imaging unit 3 is arranged in the middle of the head end, then the two side walls can be used as the turning surfaces respectively.

The present invention provides several implementations of the drive part 4. Due to the differences in the arrangement of the instrument channel 7, the drive part 4 is divided into two categories. The first category is that the drive mode meets two different instruments. How channel 7 is set. Specifically, the upper end surface of the mounting base 2 is provided with a connecting portion 5, and the imaging portion 3 is movable on the connecting portion 5. The driving portion 4 includes a traction rope 14, and the traction rope 14 is used to pull the imaging portion 3 to switch from the first working state to The second working state; and/or, the pulling rope 14 is used to pull the camera unit 3 to switch from the second working state to the first working state. It should be noted that the camera unit 3 may have a reset member, and the traction rope 14 is used to pull the camera unit 3 to switch from the first working state to the second working state. Due to the existence of the reset member, if there is no traction rope 14 As a result of traction, the imaging unit 3 will actively return from the second working state to the first working state. That is to say, the traction rope 14 is only used for pulling the imaging unit 3 to switch from the first working state to the second working condition; Switching to the second working state and switching from the second working state to the first working state.

Under the first category, there are two specific driving methods, please refer to Figure 1-Figure 3 and Figure 4-Figure 5, the first type is that the connecting part 5 includes the first elastic member 16, and the camera part 3 is close to the mounting seat One end of 2 is connected to the first elastic member 16; at least one traction rope 14 is set, and the traction rope 14 is arranged on the first side wall 12, which is used to pull the first side wall 12 from the state perpendicular to the mounting base 2 to close and parallel In the state of mount 2. This is the situation that the above-mentioned traction rope 14 is only used for pulling the camera unit 3 to switch from the first working state to the second working state. The first elastic member 16 can be a shrapnel or a spring or an elastic tendon. In the first working state, The first elastic member 16 is in the initial state. When the traction rope 14 drives the first side wall 12 to turn over and the camera unit 3 is switched to the second working state, the first elastic member 16 is in an elastically deformed state (stretched state). When the pulling effect of the pulling rope 14 is cancelled, the imaging unit 3 will return to the first working state under the restoring force of the first elastic member 16 . It should be noted that if the opening 8 belonging to the instrument channel 7 is arranged on the upper end surface of the mounting base 2, the imaging unit 3 is covered at the opening 8 in the first working state, and in the second working state, the imaging unit 3 The flipping of makes the opening 8 exposed. It should also be noted that due to the pulling effect of the first elastic member 16, the traction to the imaging unit 3 can be stopped at any position, so that the traction force and the restoring force are balanced, and the imaging angle of the imaging unit 3 can be switched at will, which is more beneficial to the patient. Observation of the affected area.

Please refer to FIGS. 6-8 , the second driving method is that the connecting part 5 includes a rotating shaft 17, and the imaging part 3 is connected to the rotating shaft 17 in rotation; there are at least two traction ropes 14, and one traction rope 14 is arranged on the first side wall 12 , another traction rope 14 is arranged on the bottom end 21 of the camera part, and a traction rope 14 is used for pulling the first side wall 12 to convert from extending along the front view direction (in this embodiment, perpendicular to the state of the mounting base 2) to being close to (In this embodiment, it is parallel to the mounting seat 2) The state of the mounting seat 2, another traction rope 14 is used to pull the bottom end 21 of the imaging section to reset the first side wall 12, so that the traction rope 14 can be lifted To a certain degree of accommodation, prevent the traction rope 14 from scratching the patient's intestinal tissue. This is the case where the above-mentioned traction rope 14 is used to pull the imaging unit 3 from the first working state to the second working state and from the second working state to the first working state. Since the rotating shaft 17 cannot provide reset force, it can only The imaging unit 3 is rotatably connected thereto, so two traction ropes 14 are needed to pull the first side wall 12 and the bottom end 21 of the imaging unit to switch the state of the imaging unit 3 . It should be noted that two traction ropes 14 can be used to cooperate with each other to achieve the adjustment of the camera angle of the imaging unit 3, and of course a plurality of traction ropes 14 can be arranged on one side to achieve a more stable traction effect. This is not limited. It should also be noted that if the opening 8 belonging to the instrument channel 7 is arranged on the upper end surface of the mounting base 2, the imaging unit 3 is covered at the opening 8 in the first working state, and the imaging unit 3 is covered in the second working state. The overturning of 3 exposes the opening 8.

It should be noted that the limit position of the imaging unit 3 in the second state is generally set parallel to the upper end surface of the mounting base 2, but in actual use, it may be required to be at a position lower than the inner wall of the patient's intestine (lower than the mounting base 2). 2), so there may be visual blind spots. First of all, in the technical solution provided by the present invention, since the connecting portion 5 has a certain height, when the imaging portion 3 moves to the second working state, it is supported by the connecting portion 5, and the imaging portion 3 is not completely compatible with the installation. The upper end surface of the seat 2 is attached, and there is a certain inclination angle, which can expand the viewing angle range of the imaging unit 3, so that the imaging unit 3 can observe the lower position; in addition, the upper end surface of the mounting base 2 has a slope (in the attached Not marked in the figure), in the first working state, the inclined plane is set away from the imaging unit 3, and in the second operating state, the imaging unit 3 is arranged close to the inclined plane, and the setting of the inclined plane can further increase the inclination angle and expand the visual field of the imaging unit 3. Range; Of course, the effect of adjusting the visual range can also be achieved by adjusting the installation angle of the camera 9. When the inclined plane is set, the camera 9 can be vertically arranged on the upper end of the camera part 3. When the inclined plane is not provided, the camera 9 can be selected to be inclined. The upper end of the imaging unit 3 is not limited in the present invention.

Further, the mounting base 2 is also provided with a guide part 6 for guiding the movement of the instrument. Specifically, there are two cases. When the opening 8 is opened on the side wall of the mounting base 2, the instrument channel 7 is close to the A guide wall 19 is formed at the opening 8, and the guide wall 19 guides the instrument so that the instrument can protrude from the opening 8 of the side wall of the mounting seat 2; It includes a guide block 20 arranged on the mounting base 2, and a guide wall 19 is formed on the side of the guide block 20 close to the instrument channel 7, similar to the above, the guide wall 19 can also guide the instrument.
