Chinese-style esophageal anastomat

Abstract

The invention discloses a Chinese-style esophageal anastomat and belongs to the field of medical instruments. The Chinese-style esophageal anastomat only has an anastomosis function and does not havea cutting function; on one hand, the average traction force of an anastomotic stoma can be reduced, damage to the anastomotic stoma is reduced, and on the other hand, the thickness of the anastomoticstoma can be increased, the longitudinal suture length is longer, and therefore anastomosis is firmer and more stable, the structure is simple, and operation is convenient; and the surgical efficiencycan be improved, and the morbidity of postoperative anastomotic fistula is reduced. The Chinese-style esophageal anastomat comprises a gun head, a gun body and a power supply device, and is characterized in that a joint is arranged between the gun head and the gun body; the gun head, the joint, the gun body and the power supply device are fixedly connected in sequence; the joint is of a corrugated pipe structure and can be twisted; a nail storage device is arranged in the gun head, and a plurality of nail holes are formed in the gun head; the nail storage device is detachably provided with anastomosis nails corresponding to the nail holes; a nail pushing device is arranged in the gun body; and a switch is arranged on the gun body.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a Chinese-style esophageal stapler. Background technique [0002] With the development of technology, various surgical instruments emerge in an endless stream, among which staplers are particularly important. Common digestive tract stapler, the anastomosis formed is full-thickness end-to-end anastomosis, but because esophageal cancer surgery is different from intra-abdominal digestive tract anastomosis, the anastomosis in esophageal cancer surgery is anastomotic due to the gravity of the tubular stomach pulling the anastomosis The continuous tension of the mouth, when the anastomotic stoma is in the edema stage, due to the effect of traction tension, the anastomotic stoma will be affected and easily damaged, resulting in anastomotic leakage. [0003] The incidence of anastomotic leakage with traditional staplers is 12%, of which the incidence of cervical anastomotic leakage is...

AI Technical Summary

Problems solved by technology

Because after anastomotic leakage occurs, digestive juice and food can enter the chest cavity through the fistula, leading to local or systemic infection, which greatly increases the hospitalization time and hospitalization cost of patients.
