背景技术Background technique

目前，在腹腔镜肿瘤切除手术过程中，常需用肿瘤钳夹持住肿瘤以方便进行剥离操作，由于腹腔镜切口小，无法使用开腹手术用的剪刀式肿瘤抓钳，而且传统的腹腔镜抓钳钳夹多为两角型的片状结构，对组织表面粘滑的肿瘤，容易因夹持范围和力度不够造成肿瘤的滑脱，或者因钳夹过于尖利而使肿瘤组织破裂，这就增加了手术的难度，影响手术的正常进行，同时延长了手术时间，增加感染的机率，不利于术后伤口的恢复，更增加了手术的风险。 At present, in the process of laparoscopic tumor resection, it is often necessary to use tumor forceps to hold the tumor to facilitate the stripping operation. Due to the small laparoscopic incision, it is impossible to use scissor-type tumor graspers for laparoscopic surgery, and the traditional laparoscopic The clamps of the grasping forceps are mostly two-cornered sheet-like structures. For tumors that are sticky and slippery on the tissue surface, it is easy to cause the tumor to slip due to insufficient clamping range and strength, or to rupture the tumor tissue due to too sharp clamps, which increases It increases the difficulty of the operation, affects the normal operation of the operation, prolongs the operation time, increases the chance of infection, is not conducive to the recovery of the postoperative wound, and increases the risk of the operation. the
