[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, the utility model provides an endoscope forceps channel detection device, including a shell 1, the inner wall of the shell 1 is provided with a guide assembly, the inner wall of the shell 1 is provided with a winding mechanism 2, the winding mechanism 2 includes a rotating shaft 201, the inner wall of the rotating shaft 201 is plugged with a pull rod 204, the outer wall of the rotating shaft 201 is wound with a detection tube 5, the inner wall of the shell 1 is fixedly connected with a volute spring 203, the inner wall of the shell 1 is fixedly connected with a partition 202, the right inner wall of the shell 1 is provided with a groove 4, the left outer wall of the pull rod 204 is provided with a card slot 205, the inner wall of the pull rod 204 is elastically connected with a movable plate 207 through a connecting spring 206, the outer wall of the movable plate 207 is fixedly connected with a card block 208, and the right inner wall of the rotating shaft 201 is fixedly connected with a protrusion 209.

[0022] The above scheme is adopted: the detection tube 5 is the existing technology, and a camera is arranged at its front end. When inspecting the inside of the endoscope clamp channel, the detection tube 5 can be inserted into the clamp channel, and the inner wall of the clamp channel can be observed through the camera to detect whether the inner wall is damaged, etc.; the shell 1 can retract and place the detection tube 5. Since the endoscope clamp channel is generally long, the detection tube 5 is also long. Placing it in the shell 1 can be convenient for carrying and has a certain protective effect; through the winding mechanism 2, the detection tube 5 can be pulled out to a suitable length and fixed when in use. When not in use, the detection tube 5 can be automatically retracted and wound around the rotating shaft 201, and through the guide component, the detection tube 5 can be prevented from being wound in a messy manner during the process of being wound around the rotating shaft 201, thereby ensuring its neatness; one end of the detection tube 5 passes through the outer wall of the shell 1, and the detection tube 5 can be pulled out by pulling this end, while the other end is fixed to the right outer wall of the rotating shaft 201.

[0023] like Figure 2 and Figure 4As shown, the rotating shaft 201 is rotatably connected to the inner wall of the shell 1, one end of the spiral spring 203 is fixedly connected to the outer wall of the partition 202, and the other end of the spiral spring 203 is fixedly connected to the outer wall of the rotating shaft 201; the rotating shaft 201 is rotatably connected to the inner wall of the partition 202, and the protrusion 209 is engaged with the slot 205; one end of the connecting spring 206 is fixedly connected to the inner wall of the pull rod 204, and the other end of the connecting spring 206 is fixedly connected to the outer wall of the movable plate 207, the outer wall of the movable plate 207 is slidably connected to the inner wall of the pull rod 204, and the block 208 is engaged with the groove 4.

[0024] The above scheme is adopted: two groups of blocks 208 are provided on the movable plate 207, one group on the left is located inside the shell 1, and the other group on the right is located outside the shell 1. When the block 208 on the right is pressed, the block 208 on the left can be driven to move inward at the same time; when it is necessary to pull the detection tube 5 to be pulled out for use, the pull rod 204 can be pulled outward, and when the pull rod 204 moves to the position where the left block 208 corresponds to the groove 4, the elastic force of the connecting spring 206 can drive the two groups of blocks 208 of the movable plate 207 to pop out at the same time, and the left block 208 is engaged with the groove 4, so that the pull rod 204 can be fixed; the protrusion 209 is disengaged from the slot 205, and the The limit of the rotating shaft 201 is released, and when the detection tube 5 is pulled, the rotating shaft 201 can be driven to rotate, and the volute spring 203 can be forced to contract; when the detection tube 5 is pulled out to a suitable length, the right-side block 208 can be pressed to drive the left-side block 208 to move inward at the same time to disengage from the groove 4, and the pull rod 204 is pushed inward to make the slot 205 engage with the protrusion 209. The slot 205 is provided with multiple groups, which are opened in a circular array on the left outer wall of the pull rod 204 to facilitate the engagement with the protrusion 209; because the pull rod 204 is slidably connected to the right inner wall of the shell 1, it can only move horizontally but not rotate, so the rotating shaft 201 can be limited and the length of the detection tube 5 pulled out can be fixed.

[0025] When the protrusion 209 is engaged with the slot 205, the left block 208 is squeezed by the right inner wall of the rotating shaft 201 and remains in the state of being inside the pull rod 204. When the pull rod 204 is pulled, there is no need to press the block 208 and it can be pulled out directly. After the use of the detection tube 5, the pull rod 204 can be pulled out again to make the protrusion 209 disengage from the slot 205. At this time, the volute spring 203 rebounds due to the elastic force and drives the rotating shaft 201 to rotate in the opposite direction, so that the detection tube 5 can be folded up and wound around its outer wall to complete the automatic winding.

[0026] like Figure 2 and Figure 3As shown, the guide assembly includes a synchronous wheel A301, the outer wall of which is connected to a synchronous wheel B303 through a synchronous belt 302, the inner wall of the shell 1 is rotatably connected to a threaded rod 304, the outer wall of the threaded rod 304 is threadedly connected to a slider 305, and the outer wall of the slider 305 is fixedly connected to a guide plate 306; the synchronous wheel A301 is fixedly connected to the left outer wall of the rotating shaft 201, and the synchronous wheel A301 and the synchronous wheel B303 are both rotatably connected to the left inner wall of the shell 1, and the synchronous wheel B303 is fixedly connected to the left outer wall of the threaded rod 304; the slider 305 is slidably connected to the inner wall of the shell 1, and the detection tube 5 passes through the outer wall of the guide plate 306.

[0027] The above scheme is adopted: when the detection tube 5 is pulled or automatically rolled up, the rotating shaft 201 rotates, which can drive the synchronous wheel A301 to rotate, and drive the synchronous wheel B303 to rotate synchronously through the synchronous belt 302. The synchronous wheel A301, the synchronous wheel B303 and the synchronous belt 302 are all existing technologies, and the gear blocks arranged on their outer walls are meshed and transmitted; when the synchronous wheel B303 rotates, it can drive the threaded rod 304 to rotate synchronously, and drive the slider 305 to move. Since the slider 305 is slidably connected to the inner wall of the shell 1, it can only move laterally on the inner wall of the shell 1, so that the threaded rod 304 is driven to rotate forward and reversely through the rotating shaft 201, and the slider 305 can be driven to move left and right in the inner wall of the shell 1.

[0028] When the detection tube 5 is wound up, driving the rotating shaft 201 and the threaded rod 304 to rotate, the slider 305 and the guide plate 306 move laterally at the same time. Since one end of the detection tube 5 is fixed to the right outer wall of the rotating shaft 201 and it penetrates the outer wall of the guide plate 306, during the winding process, the guide plate 306 can drive it to move continuously to the left, so that the detection tube 5 is gradually arranged and wound to the left during the process of winding around the rotating shaft 201, and it will not be wound multiple times at a fixed place on the rotating shaft 201, resulting in the inability to pull it; when the detection tube 5 is pulled out, the rotating shaft 201 and the threaded rod 304 can be rotated to drive the slider 305 and the guide plate 306 to move to the right, so as to pull the detection tube 5 out, thereby avoiding the problem that the detection tube 5 is piled up and entangled after automatic winding, which is relatively messy and may be inconvenient to pull out for use.

[0029] The working principle and use process of this utility model:

[0030] Before use, the detection tube 5 is wound around the rotating shaft 201 and is located inside the shell 1. When the detection tube 5 needs to be used for endoscopic clamp channel detection, the pull rod 204 is pulled outward. When the pull rod 204 is pulled to the left side of the movable plate 207, the block 208 moves to the groove 4 position, the connecting spring 206 causes the block 208 to pop out and engage with the groove 4, thereby fixing the pull rod 204. At the same time, the protrusion 209 is disengaged from the groove 205, and the limit of the rotating shaft 201 is released. At this time, the detection tube 5 is pulled to drive the rotating shaft 201 to rotate, so that the volute spring 203 is forced to contract; when the detection tube 5 is pulled out to a suitable length, the block 208 on the right side of the pull rod 204 is pressed to disengage the left block 208 from the groove 4, and the pull rod 204 is pushed inward to re-engage the protrusion 209 with the groove 205, limit the rotating shaft 201, fix the length of the detection tube 5 pulled out, and the endoscopic clamp channel detection operation can be performed.

[0031] After the detection is completed, the pull rod 204 is pulled out again to disengage the protrusion 209 from the slot 205, and the spiral spring 203 rebounds to drive the rotating shaft 201 to rotate in the opposite direction, so that the detection tube 5 is automatically retracted and wound around the rotating shaft 201, thereby achieving the effect of automatic reeling and can be stored in the shell 1, avoiding the problem that the detection tube 5 is long and inconvenient to carry, and may be tangled and messy during carrying, affecting normal use.

[0032] During the process of pulling out or winding the detection tube 5, the rotation of the rotating shaft 201 will drive the synchronous wheel A301 to rotate, and the synchronous wheel B303 will rotate synchronously through the synchronous belt 302, thereby driving the threaded rod 304 to rotate. Since the slider 305 is slidingly connected to the inner wall of the shell 1, the rotation of the threaded rod 304 will cause the slider 305 to move left and right in the shell 1; when the detection tube 5 is wound, the slider 305 and the guide plate 306 move to the left, and the guide plate 306 can guide the detection tube 5 to gradually be arranged to the left and wound on the rotating shaft 201, which is relatively neat. After the detection tube 5 is automatically wound, it will not be wound at the same place of the rotating shaft 201 to cause entanglement. When the detection tube 5 is pulled out, the slider 305 and the guide plate 306 move to the right to assist in pulling out the detection tube 5.
