Description

Stapler nail pushing seat

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a nail abutting seat of an anastomat.

Background

Staplers are devices used in medicine to replace manual suturing, the main working principle being the detachment or anastomosis of tissue by titanium staples, similar to staplers. According to different application ranges, the surgical stapler can be mainly divided into a skin stapler, a circular stapler for digestive tracts (esophagus, stomach and intestine and the like), a rectal stapler, a circular hemorrhoid stapler, a circumcision stapler, a blood vessel stapler, a hernia stapler, a lung cutting stapler and the like. The use method of the anastomat is described by intestinal anastomosis, the proximal intestine of an anastomosis port is sutured by a purse string, the nail seat is placed and tightened, the distal end of the anastomosis port is inserted into the anastomat, the anastomosis port penetrates out of a puncture outfit in the center of the anastomat and is connected with a center rod of a nail seat of a proximal anastomat, the anastomosis port is rotated to be close to the intestinal wall of a distal and proximal intestinal canal, the distance between the nail seat and a base of the anastomat is adjusted according to the thickness of the intestinal wall, a safety force is opened to pinch and close an anastomosis wrench, a 'crack' sound is heard to indicate that the cutting anastomosis is finished, the anastomat is not withdrawn temporarily, whether the anastomosis is satisfied or not and whether other tissues such as a tie membrane and the like are embedded into the anastomosis port, after corresponding treatment, the anastomat is unscrewed and is slightly pulled out from the distal end, and whether a resection loop of the distal and proximal intestinal canal is complete or not is checked.

Currently, the announcement number is: CN103156657A, discloses a nail-abutting seat assembly of a linear cutting stapler, which comprises a nail-abutting seat support and a nail-abutting seat, wherein a fixing structure for locking the positions of the nail-abutting seat support and the nail-abutting seat is arranged between the front end of the nail-abutting seat support and the front end of the nail-abutting seat, a clamping groove is arranged in the middle of the nail-abutting seat support, a protruding wing clamped with the clamping groove is arranged at the tail end of the nail-abutting seat, the front end of the nail-abutting seat is connected with the nail-abutting seat support through the fixing structure, and the tail end of the nail-abutting seat is connected with the nail-abutting seat support through the matching of the clamping groove and the protruding wing. The invention has simple assembly, low cost and convenient processing, and can finely adjust the position of the nail abutting seat during assembly.

The inside nail seat of supporting of current anastomat generally installs well core rod and links up with the base, be close to far and near end intestines tube intestinal wall through rotatory core rod, thereby can be according to the distance that intestinal wall thickness adjustment anastomat supported nail seat and base, but there are some anastomats to add the staple cartridge and support the accurate counterpoint of nail seat in the mill man-hour, thereby when medical personnel use the anastomat of these misplacements to the tissue identical, the tissue will cause the titanium nail dislocation because of nail storehouse hole and supporting the dislocation of nail seat, make the unable effective coincidence of tissue fracture, cause the oozing blood easily and arouse other operation complications. Simultaneously current anastomat mainly carries out the axial through pushing away the handle and promotes along the handle to thereby push away the cutting knife and organize it and cut off, because generally all pushing away the handle in one side of anastomat, when the anastomat is anastomosed the tissue, need vacate a hand and promote pushing away the handle, so medical personnel can only press anastomat one end or two people cooperation to press by the one hand this moment, because one end is pressed and is influenced the effective coincide of titanium nail to the tissue easily, two people operate the more extravagant manpower, the use of medical personnel to the anastomat of being not convenient for.

Disclosure of Invention
