Abstract

The invention relates to a straight nail bin structure of an intracavity cutting anastomat. The straight nail bin structure comprises a knife-equipped nail bin frame assembly, a nail-equipped assembly, a connecting assembly and an outer sleeve, wherein the nail-equipped assembly is detachably mounted on the knife-equipped nail bin frame assembly; the knife-equipped nail bin frame assembly comprises a nail bin frame and a nail propping seat; the connecting assembly comprises a connecting piece, a connecting rod and a connecting lining; a channel penetrating from front to back is formed in the connecting piece; a cutting knife penetrates through the channel; the connecting lining is arranged on the cutting knife; and a tail clamping groove for instrument percussion is formed in the rear end of the connecting lining. According to the straight nail bin structure, the connecting assembly, the nail bin frame assembly and the nail-equipped assembly are designed, the rear end of the connecting piece is connected with the connecting rod, the front end of the connecting piece is connected with the nail propping seat and the nail bin frame to form a hinge structure, and all sections of the whole structure are connected on a universal structural piece, so that the overall straightness and concentricity are stable, a produced product is more stable, and single operation is smoother and more reliable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a straight staple cartridge structure of an intracavity cutting stapler with a staple cartridge holder assembly with a knife that can repeatedly load a stapled staple assembly. Background technique [0002] The stapler is a medical device that replaces manual suturing. The main working principle is to use staples to sever or staple tissue, similar to a stapler. There are many types of staplers, which are divided into linear staplers, circular staplers, arc staplers, button-shaped staplers, and paper-shaped staples according to their shapes. The stapler is generally composed of a staple cartridge, a staple felt, a cutting knife and an instrument gun. The staple cartridge and staple felt are located on the front end of the instrument gun. During the operation, clamp and bite the tissue to be anastomosed between the staple cartridge and the staple felt, press the handle of...
