Forceps holder system based on elastic metal

Abstract

The invention discloses a forceps holder system based on elastic metal. The forceps holder system comprises a clamping part and an ejection power part. A vascular clamp in the forceps holder system is made of an elastic metal material, the tail part is connected by adopting an arc-shaped ring, elastic force is generated by virtue of the shape of the tail part, a grab handle is adopted for synchronously controlling the clamping part and the ejection power part, release of the vascular clamp is realized, after release, no matter whether tissue is edema or not, friction force of the tissue is not influenced, shaping with excessive force is not needed, the risk that the intima is broken by a hemolok does not exist, a blocking part is arranged at the connecting part of the arc-shaped ring of the vascular clamp and two elastic clamping pieces, and the blocking part can prevent the tissue from entering a tension-free area (an area in the arc-shaped ring) of the vascular clamp and losing effect. The forceps holder system disclosed by the invention is ingenious in structural design, easy to operate and easy to use, the tissue can be effectively protected from being damaged by the vascular clamp during slow release, and the vascular clamp can be applicable to an occasion with thick tissue or not suitable for excessive pressure by virtue of the design of a middle shaft of the forceps holder system; and the vascular clamp can be used without penetration in front of the tissue, and operation difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a clamp system based on elastic metal. Background technique [0002] With the development of endoscopic technology and other technologies, endoscopic hemostasis has become the first choice for the treatment of gastrointestinal bleeding. Currently commonly used hemostasis methods include laser coagulation, electrocoagulation, and vascular clipping. Among them, the vascular clip method has become the most effective method of hemostasis and has the most clinical application value because of its advantages of less trauma, faster hemostasis, and lower incidence of rebleeding. [0003] Various clamping systems are currently one of the most widely used devices in minimally invasive surgery. They are mainly used to clamp blood vessel tissue to achieve hemostasis. In a few cases, they are also used for tissue and suture fixation. Laparotomy, laparotomy is mainly used for he...

AI Technical Summary

Problems solved by technology

[0007] Defects: 1. The clipping can only be done after the opposite side is fully penetrated; 2. The clip itself is too large, which affects the operation; 3. The ultrasonic scalpel cannot be operated too close to the clip, and the heat of the ultrasonic scalpel The clip may be damaged and cause it to fall off; 4, the clamping force of the artery is too large, and there is a risk of intimal damage;

[0008]5 Occasional mechanical failure, where the front jaw structure hangs on the tissue

[0011] Defect: The titanium clip is a plastic structure, which has already been shaped after clipping the tissue, and the friction is low. Other operations during the operation are easy to entrain the titanium, and with the Occurrence of tissue edema and regression process, easy to fall off, unsafe, need to be sutured again, generally only used for temporary hemostasis

[0014] Defects: complex structure, large overall, easy to affect operation, difficult to use fine
