Endoscope double-arm closing clamp for closing digestive tract perforation

Abstract

The invention discloses an endoscope double-arm closing clamp for closing a digestive tract perforation. The closing clamp comprises a releasable clamping head assembly, a connecting block and a releasing assembly. Through the handheld part of an sliding operating handle, a side tong head can be independently controlled, and the clamping head assembly can be released. The closing clamp can processlarge perforation, the tong head can be repeatedly opened and closed, the tong head can be independently controlled, and meanwhile misoperation is prevented.

Description

technical field [0001] The invention relates to an endoscopic double-arm closing clamp for closing digestive tract perforation. Background technique [0002] Suturing is used in various medical procedures, and it is necessary to bring the side walls of the perforation together, suture the wound or connect the tissue with clips or nylon loops, but for large digestive tract perforations such as gastric perforation, ordinary grasping forceps have smaller jaws , it is often difficult to completely grasp the periphery of the perforation wound and gather it together. It is very difficult to use multiple clips at the same time, and the clips are easy to fall off, and the success rate is low. Traditional closure clips usually only have two pliers heads, which is difficult to deal with large perforations. , and the closing clip cannot be opened and closed repeatedly, resulting in a low error tolerance rate. The two pliers can only be opened or closed at the same time, and the degree ...

Traditional closure clips usually only have two pliers heads, which is difficult to deal with large perforations. , and the closing clamp cannot be opened and closed repeatedly, resulting in a low error tolerance rate, the two clamp heads can only be opened or closed at the same time, and the degree of freedom of operation is low

[0003] Although the technical solution disclosed in the application number 201410789760.5 "An Endoscopic Grasper for Closing Perforation of the Digestive Canal" can realize individual control of the forceps head, the operation is cumbersome and difficult; first, the grasping tissue is sucked into the ligation tube, Then, operate the syringe to inflate the balloon tube, and finally, the balloon tube expands to push the ligation ring on its outside to the front of the ligation tube and release it; the above three steps are cumbersome and complicated to operate, and the operation accuracy of the operator is required Therefore, how to perforate easily and quickly has become a big problem
