Novel tubular anastomat

Abstract

The invention relates to the technical field of medical instruments, and discloses a novel tubular anastomat. The novel tubular anastomat comprises an anastomat body, wherein a nail abutting base assembly is installed at one end of the anastomat body; an osculating part assembly is fixedly installed at the other end of the nail abutting base assembly; the nail abutting base assembly comprises a nail abutting base, a nail abutting base cap and a knife pad ring; the nail abutting base cap is fixedly installed at one end of the nail abutting base; the knife pad ring is clamped to the inner wall of the nail abutting base in a sliding mode; the osculating part assembly comprises a nail bin frame, a nail pushing piece, a nail bin and an annular knife; the inner wall of the nail bin frame is smooth; and two connecting ribs are fixedly connected to the middle of the nail bin frame. According to the novel tubular anastomat, the rigidity of the nail pushing piece is good, all anastomotic nails are completely closed, and the good suturing effect is achieved; the connecting portion of the nail abutting base and the nail abutting base cap is hollowed out, the nail bin and the anastomat body areconnected through two strips, the organ / tissue storage area can be greatly increased, then suturing is carried out, the suturing difficulty of a doctor is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a novel tubular stapler. Background technique [0002] The stapler is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. It is generally divided into one-time or multiple-use staplers. [0003] When the doctor performs the stapler suturing operation, he needs to insert the anvil seat assembly into the patient's organ, and then sew the suture opening of the organ on the anvil seat assembly. [0004] At present, the tubular staplers used in the market are used for suturing, and the operation space is narrow, and the staple pushers on the market are all made of plastic. Plastic parts, the deformation of the staple pusher often occurs during the operation, resulting in incomplete closure of some staples and poor suturing effect...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of tubular stapler, which ensures good rigidity of the staple pusher, ensures complete closure of all staples, and achieves a good suturing effect. The connection part is hollowed out, which can greatly increase the storage area of ​​organs / tissues, and then suture, which reduces the difficulty of suturing for doctors and improves the efficiency of surgery. Moreover, the staple pushers on the market are all made of plastic. When pushing the staples to close, due to the large force required to close them, and the staple pushers are plastic parts, the deformation of the staple pushers often occurs during the operation, resulting in partial staples being incomplete. Closed, the suture effect is poor; or the staples are directly stuck in the staple cartridge and cannot be pushed out, resulting in the failure of the operation
