Nail container of surgery suturing and cutting instrument

Abstract

The invention provides a nail container of a surgery suturing and cutting instrument. The nail container of the surgery suturing and cutting instrument comprises a nail container face. A cutter groove is vertically and inwards formed in the nail container face, and two sides of the cutter groove are respectively a tissue suturing side and a tissue cutting side. A first nail hole row is arranged on the tissue suturing side, a second nail hole row is arranged on the tissue cutting side, and both the arrangement axis of the first nail hole row and the arrangement axis of the second nail hole row are parallel to the axis of the cutter groove. The minimum distance between the arrangement axis of the first nail hole row and the axis of the cutter groove is smaller than the distance between the arrangement row of the second nail hole row and the axis of the cutter groove. The nail container of the surgery suturing and cutting instrument has the advantages that fewer suturing nails are arranged on the tissue cutting side, waste of the suturing nails is reduced, cost is saved, and the whole nail container is enabled to be easy to manufacture; few suturing nails are arranged on cut tissue, and therefore a doctor can conveniently conduct a medical examination on the cut tissue.

Description

technical field [0001] The invention relates to a staple cartridge of a surgical instrument, in particular to a staple cartridge of a surgical suture cutter, belonging to the technical 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, as disclosed in US Patent No. 7,055,730, the side-type surgical stapler can cut tissue while closing the wound. This surgical stapler can drive into two rows of staples on both sides of the tissue at the same time, and then use a cutter 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. [0003] However, because the existing instruments of this type perform the same sut...

AI Technical Summary

Problems solved by technology

[0003] However, because the existing instruments of this type perform the same suture on the tissues on both sides of the cutter during the operation, there will also be staples on the tissues that need to be cut off, resulting in a waste of staples

In addition, since doctors generally conduct further medical examinations on the excised tissues, the tissues with staples are not conducive to sectioning and inconvenient for inspection
