Abstract

The invention relates to a surgical incision stitching instrument, comprising a support rod, a nail propping seat component, a nail pushing mechanism and a limit mechanism, wherein a cover with handles, the nail pushing mechanism and the limit mechanism are fixed at the rear part of the support rod; the nail propping mechanism is connected at the front part of the support rod and comprises a nail propping seat with an opening on one side, an anvil block fixed at the front part of the nail propping seat, and a nail bin and a knife holder arranged at the rear part of the nail propping seat; a blade fixed on the knife holder penetrates through the nail bin and is positioned in the middle of nail lines; each nail pushing piece on the knife holder is arranged in each nail line of the nail bin; the sections of the nail propping seat, the anvil block, the nail bin, the knife holder and the blade are arranged to be in the shape of a polygon with more than three sides; two ends of an internal locating pin on the closed side of the nail propping seat are respectively arranged on the nail bin and the anvil block; an external locating pin is arranged on the nail bin in a penetrating way, the rear end of the external locating pin is connected with a sliding seat, and the front end of the external locating pin corresponds to a location hole on the anvil block; and an internal guide sleeve and an external guide sleeve are respectively arranged on the internal locating pin and the external locating pin and can move front and back relatively. The surgical incision stitching instrument has a simple structure and can enhance assembly efficiency and reduce manufacturing cost.

Description

technical field [0001] The invention relates to a surgical cutting and stapler, which belongs to the technical field of medical instruments. Background technique [0002] The arc-shaped cutting stapler integrates cutting and suturing, and is usually used for low anterior rectal resection. Because the arc shape of the end can fit the natural anatomy of the pelvis, it can complete tissue cancer surgery in a small space. However, the current curved cutting stapler has complex structure, low assembly efficiency and high manufacturing cost. Contents of the invention [0003] The purpose of the present invention is to provide a surgical cutter and stapler with simple structure, high assembly efficiency and low production cost. [0004] The technical solution of the present invention to achieve the above-mentioned purpose is: a surgical cutter and stapler, including a support rod, a nail abutment seat assembly, a nail pushing mechanism and a limit mechanism, a cover with a handl...
