Abstract

A digestive tract type anastomat plays an active role in promoting the reconstruction work of a digestive tract; however, the size of an anastomotic stoma of the tract type anastomat is limited by the volume of the digestive tract, 1.9%-9% of anastomotic stomas of tract type anastomats become narrow after an operation, and especially dilation of the anastomotic stomas is required after esophagus anastomosis. The invention provides a disposable medical large-opening tract type cutting anastomat for the digestive tract. The anastomat is composed of an oval plane nail anvil, an oval set position, an annular plane cutting knife, an axial transmission system, an alternate reversing transmission system, an operating handle, an extrusion distance adjusting system and a mechanical safety locking system. The anastomat breaks through the current situation that the circumferential diameter of the anastomotic stoma of the tract type anastomat can not be increased under limitation of the volume of the digestive tract, and the same anastomat is suitable for the reconstruction work of the digestive tract with different wall thicknesses, so that the purpose of reconstruction of any portion of the digestive tract is achieved, the circumferential diameter of the anastomotic stoma is effectively increased to 100 mm, the narrow anastomotic stoma after the operation is eliminated, and the occurring rate of mechanical damage to the anastomotic stoma during application of the anastomat is lowered.

Description

technical field [0001] The invention relates to a medical disposable digestive tract universal large-mouth tubular cutting anastomat, which can extend the stapling surface and the cutting surface from the end surface to the side surface, so that the anastomosis diameter is not limited by the volume of the end surface of the digestive tract, and the circumference of the anastomosis reaches 100 mm. Large-diameter cutting and anastomosis; during use, the height of the staple can be changed between 0.9-2.0mm according to the actual clinical needs, which is suitable for cutting and anastomosis of various digestive canal wall thicknesses. Background technique [0002] Since the birth of the disposable digestive canal stapler, its consistency, integrity and high efficiency have been favored by digestive tract reconstruction physicians. It greatly improves the operation speed, shortens the operation time, and reduces the trauma and pollution of the operation. Improve the success rat...
