Stapler nail cartridge anti-drop mechanism

Abstract

The invention discloses a nail-pressing nail drop prevention mechanism for a stapler's staple cartridge, which comprises a staple cartridge, two sets of clamping columns are fixedly connected to the right side of the staple cartridge, and a distribution box is arranged on the top of the staple cartridge close to the front side and the rear side. Uniform nail groove, the middle position of the top of the nail cartridge is provided with a push knife groove, the interior of the nail cartridge is provided with two symmetrical inner grooves, the inner wall of the inner groove is fixedly connected with a partition plate, and the bottom of the inner groove The position corresponding to the side inner wall and the nail groove is fixedly connected with uniformly distributed internal thread columns, and the internal threads of the internal thread columns are connected with threaded hooks, which can effectively prevent the tissue in the human body from being sutured by stapler nails. If the titanium top leaks from the nail groove on the top of the nail bin, it will avoid the suture of the sutured part not being tight enough or the tissue in the human body caused by the falling of the titanium top, which will bring health hazards to the patient's body.

Description

technical field [0001] The invention relates to the field of staplers, and more specifically relates to a staple drop prevention mechanism for staple cartridges of the stapler. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, blood vessel staplers, hernia staplers , Lung cutting stapler, etc. [0003] When the stapler is inserted into the human body for use, in order to work on the sutured part more conveniently, it is often necessary to rotate the staple cartridge to a suitable position. The titanium top inside the staple cartridge of the existing stapler is only clamped through the clamping post. During t...

Problems solved by technology

[0003] When the stapler is inserted into the human body for use, in order to work on the sutured part more conveniently, it is often necessary to rotate the staple cartridge to a suitable position. The titanium top inside the staple cartridge of the existing stapler is only clamped through the clamping post. During the rotation of the staple cartridge, the titanium top may leak from the nail groove on the top of the staple cartridge, which on the one hand may result in insufficient suture of the suture site, and on the other hand may cause the titanium nail to fall into the human body , hurt the tissues in the human body, bringing health risks to the patient's body
