Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an endoscope snare with a titanium clip. Background Technology

[0002] An endoscopic snare is a medical device used during endoscopic examinations or treatments. It is usually made of a thin metal wire that can form an adjustable ring. It is inserted into the body through the tip of an endoscope. Once it reaches the target location, the snare can open and tightly wrap around the target tissue. When removing large or specially located lesions, titanium clips are usually used to clamp the wound to prevent complications such as bleeding or perforation, thereby achieving hemostasis or wound protection.

[0003] After using a snare device, it is often necessary to immediately apply a titanium clip to protect the wound. However, currently, titanium clips and snare devices are two separate instruments. After using the snare device, it is necessary to quickly switch to titanium clips. It is not possible to have a single device that can function as both a snare device and a titanium clip, which makes it inconvenient to use and affects efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an endoscope snare with a titanium clip. By combining the snare with the titanium clip, the operator can directly use the snare or the titanium clip on a single instrument, saving the time of switching tools and making the device more convenient to use.

[0020] Please see Figure 1-6 An endoscope snare with a titanium clip includes an operating shell 1. An extension tube 2 is fixed to the inner wall of the operating shell 1. A flexible tube 3 is fixed to one end of the extension tube 2. A groove 5 is formed on the surface of the extension tube 2. A connecting plate 6 is slidably connected to the inner wall of the groove 5. A movable sleeve 4 is fixed to the surface of the connecting plate 6 and is slidably connected to the surface of the extension tube 2. A collar 7 is fixed to the surface of the connecting plate 6 and is slidably connected to the inner wall of the flexible tube 3. A sliding sleeve 8 is slidably connected to the inner wall of the extension tube 2. A connecting rod 10 is slidably connected to the inner wall of the sliding sleeve 8. A pull ring 11 is fixed to the surface of the connecting rod 10. A clamping shell 9 is provided inside the flexible tube 3. An adjusting rope 12 is fixed to one end of the connecting rod 10. Two rotating shafts 13 are fixed to the inner wall of the clamping shell 9. A clamping plate 14 is rotatably connected to the surface of the rotating shafts 13. A first guide block 15 is fixed to the surface of the clamping plate 14. The adjusting rope 12 slides through the first guide block 15. A first cutting blade 16 is fixed to the surface of the first guide block 15. Movable structures are installed on both the front and rear sides of the clamping shell 9.

[0021] Rubber friction pads are fixed to the surface of the connection between the clamping plate 14 and the rotating shaft 13, as well as the surface of the rotating shaft 13. The rubber friction pads on the surface of the rotating shaft 13 and the friction pads at the connection between the clamping plate 14 cooperate with each other to achieve a damping effect.

[0022] Alternatively, a ratchet structure can be provided between the clamping plate 14 and the rotating shaft 13. After the adjusting rope 12 is tightened, the two clamping plates 14 clamp each other in opposite directions. The ratchet structure can prevent the clamping plate 14 from resetting after the adjusting rope 12 is loosened.

[0023] The adjusting rope 12 has a certain degree of rigidity, which makes it easy to drive the clamping plate 14 to rotate. The weak area that matches the cutting blade 16 can be set at the bending position of the adjusting rope 12.

[0024] The movable sleeve 4 can drive the connecting plate 6 to slide inside the slide groove 5, allowing the connecting plate 6 to push the collar 7 out of the hose 3, thus expanding the collar 7. After the collar 7 covers the target area, the movable sleeve 4 pulls back, causing the collar 7 to re-enter the hose 3, thus tightening the collar 7. Then, by pushing the sliding sleeve 8, the sliding sleeve 8 can move the clamping shell 9 out of the hose 3 through the movable structure, allowing the two clamping plates 14 on the surface of the clamping shell 9 to approach the area to be clamped. Then, pulling the pull ring 11 causes the pull ring 11 to drive the adjusting rope 12 back through the connecting rod 10, allowing the adjusting rope 12 to pull the first guide block 15 and the clamping plates 14 to move, thereby realizing the mutual movement of the two clamping plates 14, thus completing the clamping of the target area. The clamping effect in the target area is such that after the clamping plate 14 clamps the target, continuing to pull the pull ring 11 can make the surface of the adjusting rope 12 come into contact with the first cutting blade 16, allowing the first cutting blade 16 to cut the adjusting rope 12. At this time, the clamping shell 9 can separate from the extension cylinder 2. Due to the damping effect between the clamping plate 14 and the rotating shaft 13, the clamping plate 14 can obtain clamping force, allowing the titanium clamp formed by the clamping plate 14 and the clamping shell 9 to remain in the patient's body. Through the above design, the combination of the snare and the titanium clamp is realized, allowing the doctor to complete the two steps of resection and clamping without changing different tools. This helps to shorten the overall operation time, and also reduces the positional deviation that may be caused by frequent tool changes, thus improving the accuracy of the operation.

[0025] Furthermore, the movable structure on the surface of the clamping shell 9 includes two second guide blocks 18, which are fixedly connected to the surface of the clamping shell 9. Two connecting ropes 19 are fixed on the surface of the sliding sleeve 8, and the connecting ropes 19 pass through the second guide blocks 18. Second cutting blades 20 are fixed on both sides of the front and rear surfaces of the clamping shell 9.

[0026] The connecting rope 19 also has a certain degree of rigidity, which makes it easy to move the clamp 9.

[0027] When the sliding sleeve 8 slides into the operating housing 1, the sliding sleeve 8 will drive the connecting rope 19 to move, so that the connecting rope 19 can push the clamping housing 9 to move together, thereby ensuring that the clamping housing 9 can be detached from the hose 3. After the clamping plate 14 has completed clamping, pulling the sliding sleeve 8 can make the connecting rope 19 come into contact with the second cutting blade 20, so that the second cutting blade 20 can cut the connecting rope 19, and the clamping housing 9 can be separated from the hose 3.

[0028] Furthermore, two rubber pads 21 are fixed on both the front and rear sides of the surface of the clamping shell 9, and the connecting rope 19 slides through the rubber pads 21.

[0029] The rubber pad 21 itself has good friction, which makes the connecting rope 19 more resistant to friction inside the rubber pad 21, thereby ensuring that the connecting rope 19 can drive the clamp 9 to slide normally.

[0030] Furthermore, a limiting block 23 is fixed to the inner wall of the extension cylinder 2, and the limiting block 23 is slidably connected to the surface of the sliding sleeve 8;

[0031] The setting of the limiting block 23 prevents the sliding sleeve 8 from detaching from or completely entering the operating shell 1 when it moves.

[0032] Furthermore, a guide post 17 is fixed to the inner wall of the clamp 9, and the adjusting rope 12 slides through the guide post 17;

[0033] By setting the guide post 17, the adjusting rope 12 can be guided, avoiding the accumulation of the adjusting rope 12 inside the clamp 9 and the tilting of the moving position.

[0034] Furthermore, an extension plate 22 is fixed to the surface of the sliding sleeve 8;

[0035] By setting the extension plate 22, when the operator pulls the connecting rod 10 with the pull ring 11, the extension plate 22 can be pushed to prevent the sliding sleeve 8 from moving, thereby ensuring that the connecting rod 10 can drive the adjusting rope 12 to move normally.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
