A linear stapler with double insurance

Abstract

The invention discloses a linear stapler with double insurance, which belongs to the technical field of cutting and staplers, and comprises a stapler body, one side of the stapler body is connected with a push rod, and the bottom of the stapler body is connected with a stapler handle through transmission. and the pull handle, the inner cavity of the push rod is provided with a first limiting mechanism, and a staple cartridge mechanism is fixedly connected to one side of the first limiting mechanism. In the present invention, the nail anvil can be pulled to separate from the staple cartridge, and then the nail anvil can be quickly disassembled and maintained to facilitate the replacement of the nail anvil, and the flexible airbag can be flexibly limited when it is attached to the tissue , at the same time, the airbag can be socketed outside the titanium nail body to avoid affecting the anastomotic effect of the titanium nail, and to avoid damage to the external tissue when the titanium nail body is squeezed on the rear side, thereby improving maintenance efficiency and reducing the risk of failure. The mechanical error will damage and tear the anastomotic tissue, ensuring the anastomosis cutting needs.

Description

technical field [0001] The invention belongs to the technical field of cutting and suturing devices, and particularly relates to a double-safety linear suturing device. Background technique [0002] The stapler is a surgical device for suturing and anastomotic wounds through titanium nails. It has the advantages of portable operation and can adapt to the needs of postoperative anastomosis. [0003] Chinese patent document CN103126735B discloses a linear cutting stapler, including a staple cartridge assembly, an anvil seat assembly, a component seat, a locking rod assembly, and a firing mechanism for actuating the staple anvil seat assembly. The firing mechanism includes a push block, a knife bar, Wedge, screw, drive nut, rotating handle and screw fixing seat, the screw fixing seat is fixedly connected to the bottom of the component seat, the two ends of the screw are rotatably supported on the screw fixing seat, and the rotating handle is connected to the screw fixing seat. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the lack of limit support ability for the front-end staple cartridge, which affects the need for wound bonding at the anastomotic position, and the nail cartridge assembly is relatively inconvenient, which affects the assembly efficiency, and at the same time lacks the limit reminding ability before activation , leading to the problem of accidental touch, and a double insurance linear stapler is proposed
