Abstract

The invention relates to a linear type cutting and suturing device with an inter-bridge structure. The linear type cutting and suturing device comprises a nail abutting device, a nail bin, a nail bin seat, a cutting knife and a sliding knife rail; the nail abutting device is aligned with the nail bin in an assisting mode to form a nail, the nail bin is installed on the nail bin seat, and the cutting knife is installed on the position, located at the back central axis, of the sliding knife rail; when the cutting knife moves ahead and enters the nail bin along the sliding knife rail, a sliding knife groove is reserved at the central axis of the nail bin; the cutting knife slides ahead on the sliding knife rail, enters the sliding knife groove of the nail bin and arrives at the front end, and a cutting portion is exposed to perform cutting and suturing. According to the linear type cutting and suturing device with the inter-bridge structure, suturing and cutting are synchronously completed, front end cutting and two-side suturing can be achieved, an anastomotic stoma is in a linear shape, and the inter-bridge type is in the mode that the cutting and suturing position only occurs at the front end of the action tissue, and the back end is kept complete.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a linear cutting and stapler with bridge structure for operation. Background technique [0002] 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 significantly better than the current routinely used end-to-end anastomosis. In 2009, it was included in the "American General Thoracic Surgery" textbook, which is known as the "Bible", and is now the mainstream anastomosis method for esophageal cancer surgery in the United States. In this operation, after the esophagus is severed, a linear cutting stapler is inserted into the cavity made on the esophageal stump and the gastric tube, and the esophagus and the anterior wall of the gastric tube are first linearly anastomosed laterally, and then the remaining esop...
