Linear anastomat with cutting device

Abstract

The invention relates to a linear anastomat with a cutting device, comprising an instrument body (7), a nail-abutting seat (1) and a pushing plate (6). The pushing plate (6) is mounted at the front part of the instrument body (7); the front part of the pushing plate (6) is also provided with a pushing slice (4) and a nail chamber (2) which is mounted relative to the nail-abutting seat (1); and an anastomat nail is mounted on the end surface of the pushing slice (4). The linear anastomat with the cutting device also comprises a cutting knife (3) and a knife holder (5), wherein the cutting knife (3) is fixed on the knife holder (5) which is mounted between the pushing slice (4) and the pushing plate (6); and the front end of the cutting knife (3) penetrates through a groove between the nail chamber (2) and the pushing slice (4). The invention has simple structure and convenient operation, and the aims of simultaneously sewing and cutting can be achieved by only using a single anastomat.

Description

technical field [0001] The invention relates to the field of surgical medical instruments, in particular to a linear stapler with a cutting device for surgery, which can simultaneously perform surgical suturing and cutting. Background technique [0002] Linear stapler, also known as alimentary canal closure device, is a device that can insert multiple interlaced staples in a straight line on the tissue, and is also one of the devices widely used to replace manual linear suture. It is mainly used to suture the stumps of the stomach, duodenum, small intestine, and colon, and it is a full-thickness eversion suture. [0003] In cases where it is difficult to expose the surgical field, surgeons often face many challenges, such as: ① It is difficult for instruments to enter the lower pelvic cavity; ② Instruments will block the operating field of view; ③ Sometimes multiple instruments must be prepared to adapt to different pelvic structures; ④In the lower pelvic cavity, there is n...

AI Technical Summary

Problems solved by technology

[0003] In the case where it is difficult to expose the operative field, surgeons often face many challenges, such as: ① It is difficult for instruments to enter the lower pelvic cavity; ② Instruments will block the operating field of view; ③ Sometimes multiple instruments must be prepared to adapt to different pelvic structures; ④In the lower pelvic cavity, there is no space for cutting and suturing operations; ⑤How to reduce the chance of infection and tissue trauma, etc.

[0004] At present, the traditional linear stapler has a shortcoming, that is, it only has suturing function, no cutting function, and it is inconvenient to operate.

In order to separate excess tissue, it is necessary to manually remove it with a blade, but the operating skills of doctors are different, and the cutting techniques are inconsistent, and the tissue will be damaged when performing sharp separation or electric knife separation
