Problems solved by technology

In this case, it is difficult for the arm of the existing clip-opening forceps to perform the clip-opening operation through the piercer.
Although the clip applier can be put into the trocar and enter the surgical site, it cannot provide the force required to open the ligation clip, and it is difficult to clamp and fix the ligation clip to perform the clip opening operation

Abstract

The invention discloses a pair of clamping tongs with a ligation clip opening function. The clamping tongs comprise a first tong arm and a second tong arm. The first tong arm comprises a first front arm and a first rear arm. The second tong arm comprises a second front arm and a second rear arm. The inner side face of the first rear arm and the inner side face of the second rear arm are provided with locating grooves independently or simultaneously. The clamping tongs can be used for closing a ligation clip and opening the ligation clip, and therefore one instrument achieves multiple functions.

Description

technical field [0001] The invention relates to an appliance for surgery, in particular to a clip applier with the function of opening clips, which realizes multiple functions of one device. Background technique [0002] Ligation clips are medical devices used for ligation and anastomosis of blood vessels or other tubular structures in laparoscopic surgery or surgical non-absorbable ligature clips (see figure 1 ). Under the action of the clip applier, the operator closes the open ligation clips. When the ligation clip needs to be opened due to the deviation or incorrectness of the release position, the current solution is to take out the clip applier and replace it with a clip-opening instrument to open the ligation clip. This kind of operation not only brings some inconvenience to the operation of ligation or anastomosis, but also needs forceps arms of different structures to implement due to the difference in the force required for the operation of closing and opening th...
