Nail warehouse with high-strength nail pushing sheet installation structure, and stapler comprising nail warehouse

Abstract

The invention relates to a nail warehouse with a high-strength nail pushing sheet installation structure. The nail warehouse with the high-strength nail pushing sheet installation structure comprisesa nail warehouse body; a feeding groove and containing cavities used for containing a nail pushing sheet are arranged on the nail warehouse body; the number of the containing cavities is 2; the two containing cavities are symmetrically distributed at the left and right sides of the feeding groove; for the containing cavity at the right side, a guide assembly for guiding the nail pushing sheet is arranged therein; the guide assembly comprises a first guide part, centre guide parts, a second guide part and a reinforcing arm, wherein the centre guide parts are formed by upwardly extending from the bottom wall of the containing cavity; the reinforcing arm is also formed by upwardly extending from the bottom wall of the containing cavity, and connected between the centre guide parts; therefore,the various centre guide parts are mutually associated, so that an organic stressed whole is formed; the bending condition due to the fact that the centre guide parts are independently stressed is effectively stopped; and the centre guide parts can smoothly stretch out so as to execute tissue sewing operation. The invention further discloses a stapler.

Description

technical field [0001] The invention relates to the technical field of medical device manufacturing, in particular to a staple cartridge with a high-strength nail pusher mounting structure and a stapler including the same. Background technique [0002] In laparoscopic surgery and thoracoscopic surgery, laparoscopic cutting stapler is usually used for cutting and anastomosis of esophagus, stomach, duodenum, small intestine, colon, rectum, appendix, gallbladder, pancreas and spleen in the digestive tract, It is also used in cutting and anastomotic operations such as the lung and trachea in the respiratory tract, and in the bladder and uterus in the urogenital system. Through its application, it can greatly reduce the surgical wound, shorten the operation time and improve the quality of the operation. [0003] Generally speaking, the staple cartridge and the staple cartridge frame are fixed as a whole, and a cutting groove is provided along the length thereof. Place the tissue...

AI Technical Summary

Problems solved by technology

Depend on figure 2 As shown in , it can be seen that the central guide is placed in the housing cavity in isolation, and it is made of plastic, so the central guide has low structural strength. Therefore, during the firing process, the central guide is subjected to an oblique force Bending deformation also occurs, which leads to the failure of the pusher piece to be pushed out normally, thereby affecting the normal operation of the combined suture process
