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...
