[0002] Digestive tract foreign bodies are common digestive tract emergencies. With the popularization of endoscopy and the maturity of operating techniques, endoscopic removal of foreign bodies is safe and simple, with the characteristics of simplicity, low cost, less trauma and high success rate. Endoscopic removal of foreign bodies in the digestive tract has become a very important treatment method and is widely used in emergency clinics and clinical operations.
[0003] Since the endoscopic foreign body removal device needs to extend from the channel inside the endoscope and cooperate with the lighting and imaging equipment at the end of the endoscope tube to grasp the foreign body, the existing endoscopic foreign body removal devices have some problems in the actual working process. For example, a foreign body removal device for endoscope with publication number CN219516488U can stably grasp the foreign body during the working process, but when the size of the foreign body inside the patient's digestive tract is larger than the diameter of the internal channel of the endoscope, it cannot complete the grasping and removal of the foreign body, and the practicality is poor; and the foreign body removal device with publication number CN21480 In the actual working process, although the 5260U foreign body forceps used in gastroenterology can stably limit the clamping mechanism, it does not have an anti-falling mechanism. Therefore, it is very easy to slip when clamping sharp foreign bodies, causing the foreign bodies to re-enter the human digestive tract, thereby increasing the risk of foreign body removal for patients. In addition, its clamping mechanism cannot be disassembled and installed conveniently and stably, and thus cannot ensure the stability and convenience of its subsequent inspection, maintenance, cleaning and disinfection. Therefore, we made improvements on this and proposed an automatic retractable endoscopic foreign body removal device. Utility Model Content

The flexible net bag 19 can be used to conveniently and stably collect foreign objects, which makes up for the defect that the existing endoscopic foreign body removal device cannot conveniently and stably remove larger and sharper foreign objects.
[0041] like Figure 3 , Figure 6 , Figure 8 and Fig. 9 As shown, as a preferred embodiment, on the basis of the above method, further, a first limit frame 14 is fixedly connected to the mounting plate 10, a first volute spring 15 is fixedly connected inside the first limit frame 14, an inner end of the first volute spring 15 is fixedly connected to the rotating shaft 12, a second limit frame 16 is fixedly connected to the second volute spring 17, an inner end of the second volute spring 17 is fixedly connected to the winding shaft 18, the second limit frames 16 are symmetrically distributed on the upper and lower sides of the interior of the storage frame 13, the second limit frames 16 correspond one to one to the second volute spring 17, a rubber pad 20 is fixedly connected to the top of the storage frame 13, the length and width of the rubber pad 20 are respectively greater than the length and width of the cross section of the storage frame 13, by utilizing each storage frame 13 and the corresponding rubber pad 20, while covering the foreign matter, the foreign matter can be stably clamped, thereby ensuring the convenience and safety of the subsequent removal of the foreign matter.
[0042] like Fig.10 and Fig.11As shown, as a preferred embodiment, on the basis of the above method, further, the length of the traction rope 21 is greater than the length of the endoscope 3, the top of the traction rope 21 is wrapped around the coil 25, and the coil 25 is located directly above the endoscope 3. The traction rope 21 corresponds to the storage frame 13 one by one, and the worm 22 and the worm wheel 23 can drive the coil 25 on the transmission shaft 24 to rotate in a self-locking manner. By winding up the traction rope 21, the various storage frames 13 can be driven to rotate downward at the same time. In conjunction with the rotation of each storage frame 13 and the automatic contraction of the flexible net bag 19, larger foreign bodies in the patient's digestive tract can be conveniently and stably covered, thereby ensuring the stability and convenience of subsequent removal work.
[0043] Specifically, when the automatic retractable endoscopic foreign body removal device is in use: first, the medical staff can hold the operating handle 1 and insert the endoscope 3 into the patient's digestive tract, and use the display device 2 and the camera 4 and the lighting lamp 5 on the endoscope 3 to find foreign bodies in the patient's digestive tract. When the foreign body is found, the medical staff can rotate the worm 22 on the operating handle 1. At this time, under the rotation of the worm 22, the meshing worm wheel 23 can be driven to rotate automatically, and then the coil 25 on the transmission shaft 24 can be driven to rotate. At this time, under the rotation of the coil 25, each traction rope 21 can be synchronously reeled. At this time, under the reeling action of each traction rope 21, the corresponding storage frame 13 can be pulled to rotate synchronously. At this time, each storage frame 13 rotates downward at the same time, and during the rotation of each storage frame 13, The flexible net bag 19 in the storage frame 13 can be pulled. At this time, under the pulling action of the flexible net bag 19, the reel 18 can be driven to rotate automatically, ensuring the stability of the unwinding work of the flexible net bag 19, until each storage frame 13 rotates downward to the limit position. At this time, under the rotation action of each storage frame 13, the rubber pads 20 on each storage frame 13 are squeezed and contacted with each other. At the same time, under the elastic action of the second volute spring 17 inside the second limit frame 16, the reel 18 can be driven to rotate automatically in the opposite direction, so that the flexible net bag 19 can be automatically reeled. At this time, with the rotation of each storage frame 13 and the automatic contraction of the flexible net bag 19, larger foreign bodies in the patient's digestive tract can be conveniently and stably covered, and at the same time, the foreign bodies can be stably clamped, thereby ensuring the convenience and safety of the subsequent removal of the foreign bodies.
[0044] After the medical staff has taken out the picked-up foreign body from the patient's digestive tract by pulling the endoscope 3, the medical staff can unwind the traction rope 21 on the coil 25 by rotating the worm 22 in the opposite direction through the worm gear 23 and the transmission shaft 24. At this time, the traction force of the traction rope 21 disappears, and under the elastic action of the first volute spring 15 inside the first limit frame 14, the elasticity of the first volute spring 15 is greater than the elasticity of the second volute spring 17, and the storage frame 13 can be driven by the rotating shaft 12 to automatically rotate in the opposite direction and reset. At this time, the flexible net bag 19 is synchronously reset and is in an open state. Therefore, the foreign body picked up in the flexible net bag 19 can be conveniently transferred to other positions, ensuring the stability and convenience of the subsequent repeated working state of the foreign body removal device.
[0045] After the device is used, the medical staff can pull the clamping rod 9 on the positioning frame 7 outward until the clamping rod 9 moves out of the clamping slot 11 on the mounting plate 10. At this time, the mounting plate 10 can be easily separated from the positioning frame 7, completing the disassembly of the positioning frame 7 and the storage frame 13, thereby ensuring the convenience of subsequent inspection, maintenance, cleaning and disinfection of the retrieval device. When the inspection, maintenance, cleaning and disinfection of the retrieval device are completed, the medical staff can pull the clamping rod 9 on the positioning frame 7 outward again and insert the mounting plate 10 into the positioning frame 7. Then the medical staff can release the clamping rod 9 on the positioning frame 7. At this time, under the elastic action of the connecting spring 8, the clamping rod 9 can be driven to automatically engage with the clamping slot 11 on the mounting plate 10, completing the splicing of the retrieval device, and ensuring the stability and convenience of the subsequent working state of the retrieval device.
[0046] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the utility model; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are included in the scope of the claims of the utility model.
