Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a stapler for closing surgical incisions which is convenient for disinfection. Background technique [0002] Skin anastomosis (suture) stapler is a medical device for suturing human epidermal wounds to promote wound healing and postoperative wounds without removing stitches. , nail pushing piece and return spring, etc. During operation, align the nail outlet of the skin anastomotic (suture) stapler with the suturing site, press down the moving handle, and make the staples in the staple magazine meet resistance and form on the wound, so that The open wound is closed to achieve the purpose of suturing. It is suitable for superficial skin suture of human trauma and surgical incision and patch fixation for abdominal hernia repair. The principle of skin stapler is similar to that of a stapler. It has simple operation, fast suturing speed, With the advantages of good posto...

Problems solved by technology

[0003] However, the existing staplers require the operator to press the handle to fix the staples on the wound, which is time-consuming and labor-intensive. During the operation, the staples will be stuck in the staple opening due to the insufficient force used by the operator. , resulting in damage to the stapler, causing secondary damage to the wound and prolonging the operation time. At the same time, the staple cartridge in the prior art is in a closed type, and it is difficult to disinfect it
