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.
