Nail pushing pieces and suturing nails which are in butt joint are arranged in the suturing nail placing holes. Nail pushing pieces and suturing nails which are in butt joint are arranged in the pocket nail placing holes. A line accommodating groove is further formed in the nail cartridge face and communicated with at least one part of pocket nail placing holes to form a certain angle, and a pocket line is arranged in the line accommodating groove and located between two nail feet of at least one part of pocket nails. The surgical operating instrument has the advantages that the surgical operating instrument is suitable for a low rectal cancer resection, can effectively and completely excise left diseased tissue ends and greatly reduces the occurrence possibility of medical negligence.

Description

technical field [0001] The invention relates to a surgical instrument and belongs to the technical field of medical instruments. Background technique [0002] Surgical instruments such as surgical closure cutters are often used in pathological diagnosis and treatment in fixed resection. Surgical closure cutters have been developed over the past time, especially surgical instruments that can be used in smaller surgical spaces, such as the treatment of low rectal cancer, cutting of hemorrhoids, etc., and such surgical instruments are very suitable for some small surgical procedures.

Chinese patent CN200410103279 and U.S. patents US6805273 and US6817508 all disclose a surgical instrument, which generally includes a body, a nail cartridge and an anvil arranged at the distal end of the body, and a propulsion mechanism and a nail anvil arranged in the body for driving the movement of the nail cartridge. The firing mechanism used to push the...

AI Technical Summary

Problems solved by technology

However, this operation faces a problem: after the cancerous tissue is resected with a surgical closed cutter, two sharp corners will be left on the stump, commonly known as "cat ears" in the industry, and these two "cat ears" are difficult to be completely removed. resection

When the anastomosis is performed with a round tube anastomosis instrument, the staples on the "cat's ears" will be cut off, which will affect the shape of the staples at the staple cutting site, cause bleeding, and postoperative excrement will enter the tip Horns, easy to infect wounds, sharp corners in the body will also cause certain damage to other tissues
