Abstract

The invention discloses a linear cutting stapler with intracavity bridge structure, which comprises a cutter head and a cutter shank. The cutter head is positioned on one side of the cutter bar, a mounting seat is fixedly installed on the side of the knife bar close to the knife head, a side of the mounting seat close to the cutter head is provided with a slot for sleeving the cutter head, one side of the cutter head is positioned in the slot, two first mounting cavities are symmetrically arranged in the mounting seat, one side of the mounting seat is provided with a first opening communicating with the first mounting cavity, one end of the mounting rod extends outside the mounting seat through the first opening, and an extension end of the mounting rod is fixedly connected with a controlhandle. The invention facilitates the replacement of the cutting knife head on the linear cutting stapler with the bridge structure in the cavity, so as to facilitate the smooth operation of the medical personnel and the success of the operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a linear cutting stapler with an intracavity bridge structure. Background technique [0002] The morbidity and mortality of esophageal cancer in my country rank first in the world. As far as the current treatment status of esophageal cancer is concerned, it is difficult to significantly improve its 5-year survival rate in the short term, and it is a more realistic goal to try to improve the quality of life of patients and improve the safety of surgery. Anastomotic stenosis and reflux are two aspects that seriously affect the quality of life of patients after surgery, while anastomotic leakage affects the safety of surgery. [0003] Esophagogastric "side-to-side anastomosis" is a new type of anastomosis recently developed at home and abroad. Many literatures have reported that its anti-stenosis, anti-reflux and anti-anastomotic leakage characteristics are significantl...
