Surgical stapler staple-cabin assembly with mounting security safety unit

Abstract

The invention relates to a surgical stapler staple-cabin assembly with a mounting security safety unit. The surgical stapler staple-cabin assembly is a surgical stapler supporting device for applyinga linear-row stapler to intra-cavity tissue and meanwhile cutting the tissue within the linear-row stapler, and is used for avoiding the situation that a staple cabin assembly is not assembled well and accordingly cannot be in use. The surgical stapler staple-cabin assembly includes a staple abutting base, a staple cabin base, rotary head pins, an upper rotary joint, a lower rotary joint, staple cabin spring pieces, a staple cabin, a push block, push pieces, suture staples, staple cabin base pins, an upper half shell, a lower half shell, H-shaped blocks, rising prevention plates, an arc clamp,a cutter, a drive sleeve, a sleeve pipe, a steering pull hook and a protection cover. A limit block is arranged at the inner side of the arc clamp, two clamp pins are arranged at the tail end of thearc clamp, and a fixing point is arranged at the tail end of each clamp pin. A cutter guide groove is formed in the middle of the lower half shell, an arc clamp guide hole is formed in the middle-backportion of the lower half shell, two guide fixing blocks are arranged at the tail end of the lower half shell, two limit pits are formed in front of the guide fixing blocks respectively, and a limitopening is formed in the tail end of a cutter assembly.

Description

technical field [0001] The present invention relates to a surgical stapler staple cartridge assembly with a safety safety device installed, which is a surgical stapler matching device that applies linear rows on intracavity tissue and cuts tissues between the linear row staplers at the same time. It is used to avoid the situation that the staple cartridge assembly cannot be used due to improper assembly. Background technique [0002] In the traditional or open procedure, the doctor directly touches the surgical site. Due to the relatively large trauma of the surgical incision, the patient feels great pain and the postoperative recovery is slow. In minimally invasive surgery, the patient is undergoing abdominal or endoscopic surgery, in which the procedure is performed through a small incision on the patient's body or through a narrow cannula inserted into the wound. Minimally invasive surgery has advantages over open surgery due to its reduced patient trauma, shortened pati...

Problems solved by technology

[0003] At present, the laparoscopic cutting staplers used in the market are complicated to install safety devices, have many parts, and have low reliability.

At the same time, due to the installation of multiple complex parts, the production cost is increased, and the medical cost of the patient is increased, which is not conducive to the wide-scale popularization and use of surgical instruments.
