Three chain-riveting type incising stitching instrument

Abstract

The invention relates to a cutter stapler with three rows of staples. The cutter stapler comprise a stapler body, a handle arranged at the rear end of the stapler body, a staple box and a cutter arranged at the front end of the stapler body and a staple pushing chip which is arranged in the staple box and used for propelling the staple to move, wherein, a plurality of staple holes which allow the staples to pass through and a cutter slot which allows the cutter to run through are arranged on the staple box; the staple box has a structure with three rows of staples, which reduces the thickness of the whole staple box component so that the head of the cutter stapler is lighter, easy operation can be ensured in the surgery and the surgery can also be conducted deep in a narrower pelvic cavity; moreover, the structure with three rows of staples can ensure that only one row of staples are reserved on a sample, which avoids unnecessary waste and reduces the cost of operation.

Description

technical field [0001] The invention relates to a three-row nail-type cutter and stapler for surgery. Background technique [0002] Surgical resection is one of the effective means to treat diseases such as rectal cancer, and cutting and staplers are widely used in resection to make the operation safer. The diseased tissue removed during the operation is called the specimen end. In order to prevent feces or diseased cells in the specimen end from falling into the abdominal cavity, the specimen end needs to be closed and then resected. Therefore, at least one row of staples needs to be set on the specimen end. At present, most of the staple magazines on the cutting stapler have a structure of four rows of staples. During the operation, four rows of staples are driven into the tissue to be sutured. After cutting, there are two rows of staples on the retained tissue and the end of the specimen. This structure causes The head of the cutting and stapler is too thick and inconven...

Problems solved by technology

At present, most of the staple magazines on the cutting stapler have a structure of four rows of staples. During the operation, four rows of staples are driven into the tissue to be sutured. After cutting, there are two rows of staples on the retained tissue and the end of the specimen. This structure causes The head of the cutting stapler is too thick and inconvenient to operate, and it cannot enter the narrower pelvic cavity, so that patients with ultra-low rectal cancer lose the opportunity to be treated by surgery, and two rows are set on the specimen end Staples cause unnecessary waste and increase the cost of surgery
