Nail barn of linear type cutting closer

Abstract

The invention provides a nail barn of a linear type cutting closer, comprising a body extending along the longitudinal direction. The body comprises a top face and side faces, wherein the top face is provided with nail holes and cutting grooves; the nail holes are provided with suturing nails; and the distance from the central line of the cutting grooves to the central line of the adjacent nail holes is 1.85 mm to 1.95 mm. In the invention, a stitched tissue is not easy to remove from the nail, and a knife can well complete cutting of the tissue, thereby enhancing the safety of appliances.

Description

technical field [0001] The invention relates to a surgical binding instrument, in particular to a staple cartridge of a surgical linear cutting closer, which belongs to the field of medical instruments. Background technique [0002] Surgical binding instruments are important tools for wound suturing in surgical operations, and there is a trend of eliminating manual suturing at present. Among them, the linear cutting closer can cut tissue while closing the wound. This stapling instrument can drive into two rows of staples on both sides of the tissue at the same time, and then use a push knife to cut and separate the sutured tissues on both sides. At present, this stapler is widely used clinically for side-to-side anastomosis of the stomach and jejunum, as well as operations such as the production of gastric tubes and partial lung resection. The advantage is that the suture length is long, and tissue cutting can be performed while suturing the tissue. [0003] U.S. Patent N...

AI Technical Summary

Problems solved by technology

After the current cutter cuts the tissue, the staple line of the tissue is too close to the edge of the tissue, making the staple slip off easily, but the staple line of the tissue is too far away from the edge of the tissue, which will also make cutting difficult and affect the use of the instrument
