Digestive tract metal clip unlocking extractor

Abstract

The invention discloses a digestive tract metal clip unlocking extractor which comprises a handle, rotating parts, an adjusting device, a transmission rod set, transmission pipes and a clamping device. The adjusting device is provided with a set of opposite sliding rails and provided with sliding blocks, the straight rod ends of two transmission rods of the transmission rod set are correspondinglyconnected with the sliding blocks of the adjusting device respectively, and bent parts are arranged in an X-shaped staggered mode. The adjusting device and the two transmission rods are externally sleeved with the transmission pipes, one end of each transmission pipe is fixed to the corresponding rotating part, and sliding grooves corresponding to the sliding blocks are reserved in the transmission pipes; the clamping device is hinged to a hinge column and is in a scissor shape. The two sliding blocks are pushed to drive the transmission rods to act to enable the clamping device to achieve different clamping actions, meanwhile, the rotating parts are rotated to drive the clamping device to rotate, angle fine adjustment of the clamping device is achieved, a hemostatic clip is more convenient to detach, secondary damage to a patient is avoided, no pain is caused, and wound recoquite is better facilitated.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to an unlocking and extracting device for digestive tract metal clips. Background technique [0002] At present, foreign body forceps and the like are usually used at home and abroad to remove the metal clips clamped in the tissue under the digestive endoscope. Metal clips are used to prevent bleeding and perforation during surgery, and they need to be clamped deeply and tightly. However, after the wound has healed, the metal clips are not easy to fall off and difficult to remove. Violent removal may cause new trauma. Although the foreign body pliers can remove some metal clips after mastering the skills, it is not a special instrument after all, and it is often time-consuming and laborious. The key reason is: to easily remove the metal clip, you must first separate its two toothed feet, or first pull out one of its toothed feet. [0003] But in fact, after the metal clamp is clo...

AI Technical Summary

Problems solved by technology

[0003] But in fact, after the metal clamp is closed, the gap between the two teeth is very small, and the two teeth of the foreign object pliers are very thick, so it is impossible to drill between the metal clamp teeth, separate the teeth feet, and it is difficult to clamp One tooth foot of the metal clip is pulled out, so the metal clip can only be pulled out from the tissue, so some can't be pulled out, some can only be pulled out with great effort, and some can cause new bleeding after pulling out. Metal clips for hemostasis, some parts with weak tissues, and hastily pulling out the metal clips for perforation are also common
