Nail bin for endoscope cutting anastomat

Abstract

The present invention disscloses a nail bin for endoscope cutting anastomat. The nail bin comprises a support, a nail bin piece is arranged in the support, a second knife groove is formed in the right side of the upper end of the support, a first knife groove is formed in the middle of the upper end of the nail bin piece, and a cutting device is jointly installed in the first knife groove and the second knife groove in a sliding mode; and the front portion and the rear portion of the upper end of the nail bin piece are each provided with three rows of nail outlet holes distributed at equal intervals, the upper portion of the front end of the support and the upper portion of the rear end of the support are each provided with a third through hole, and fixing pieces are arranged in the third through holes. According to the Nail bin for endoscope cutting anastomat, thick tissue can be sutured and cut, the suturing and cutting effect is guaranteed, a buffer pad and an abutting block can protect the cutting edge of a cutting knife, and the service life of the cutting knife is prolonged; the nail bin piece and the support can be quickly mounted and dismounted through the fixing piece; in addition, due to the arrangement of the infrared transmitter and the infrared receiver, the suturing nails can be conveniently and smoothly discharged, and smooth operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of staplers, in particular to a staple cartridge for an endoscopic cutting stapler. Background technique [0002] Medical stapler is a medical device often used in surgical operations on intestinal and other physiological tissues. It is a medical device used to replace traditional manual suturing. Endoscopic cutting stapler is one of the medical staplers. As an important part of the endoscopic cutting stapler, the staple cartridge often has the following problems during use: 1. The setting of the push nail seat and the staple in the existing staple cartridge can only perform a single staple height suturing operation on the tissue, It is inconvenient to suture thick tissues, resulting in poor suturing effect and affecting the healing effect; 2. Most of the cutting knives in the existing staple magazine are single-piece structure, resulting in high resistance during cutting, which affects the cutting speed and...

[0002] Medical stapler is a medical device often used in surgical operations on intestinal and other physiological tissues. It is a medical device used to replace traditional manual suturing. Endoscopic cutting stapler is one of the medical staplers. As an important part of the endoscopic cutting stapler, the staple cartridge often has the following problems during use: 1. The setting of the push nail seat and the staple in the existing staple cartridge can only perform a single staple height suturing operation on the tissue, It is inconvenient to suture thick tissues, resulting in poor suturing effect and affecting the healing effect; 2. Most of the cutting knives in the existing staple magazine are single-piece structure, resulting in high resistance during cutting, which affects the cutting speed and cutting effect; 3. After the cutting is completed, the cutting knife in the existing staple cartridge is very easy to collide with the inner wall of the staple cartridge, thereby wearing the blade and affecting the service life of the cutting knife; 4. The existing staple cartridge is not convenient for suturing staples. The dismantling and maintenance operation of the nail loading and the staple cartridge makes the use of the staple cartridge very inconvenient; 5. The existing staple cartridge is very easy to be unable to smoothly eject the nail due to the inaccurate position of the mounting seat during the nail ejection process, thus affecting the operation the smooth progress
