Problems solved by technology

[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 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

Embodiment 1

[0041] Embodiment one, see Figure 1 to Figure 9 As shown, an endoscopic double-arm closure clamp for closing digestive tract perforation according to the present invention includes a releasable clamp assembly, a connecting block 200 and a release assembly. The releasable chuck assembly is provided with a tightening tube 100 and two sets of side clamp assemblies, the front end of the tightening tube 100 is fixed with a fixed clamp head 110, and the front part of the tightening tube 100 is provided with a guide pin 120 Each set of side clamp assemblies includes elastic side clamp heads 510, the two side clamp heads 510 are respectively located on both sides of the guide pin 120 and are respectively matched with the two sides of the fixed clamp head 110, the Two first limiting holes 131 are provided at the middle and rear of the tightening tube 100, and the end of the side clamp head 510 is provided with a one-way limiting member and a snap-off part, and the one-way limiting mem...

Embodiment 2

[0046] Embodiment two, see Figure 10 As shown, the difference between the second embodiment and the first embodiment is that the engaging part of the second embodiment includes a hemispherical body 523 that can be engaged with the two pin holes 521 respectively. Under the action of an external force, the pulling wire 530 pulls The tension rod 520, the hemispherical body 523 on the clip-on part breaks away from the pin hole 521 of the tension rod 520, further makes the tension rod 520 fall into the inside of the connecting block 200, and can be released without breaking the pin hole 521 Chuck assembly.

Embodiment 3

[0047] Embodiment three, see Figure 11 As shown, the difference between Embodiment 3 and Embodiment 1 is that the handles of the two operating handles in Embodiment 3 are ring structures, and the handles of the two ring structures are respectively slidably connected to the left and right sides of the operating handle. The two operating handles are detachably spliced ​​together, and the index finger and middle finger of the same hand can be used to respectively control the holding parts of the ring structure of the two operating handles to complete one-handed operation.

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.
