Esophagus and stomach asymmetric anastomat with anti-reflux effect

Abstract

The esophagus and stomach asymmetric anastomat is characterized in that the end face of a nail bin is formed by connecting and closing two arc-shaped plates bent in the same direction end to end to form an arc-shaped cavity, nail outlet holes in the arc-shaped plates are formed around the arc-shaped cavity, and a cutter is consistent with the arc-shaped cavity in shape and is attached to the edge of the inner side wall of the arc-shaped cavity; a nail cutting board on the bottom face of the nail abutting base is formed by digging a cutting groove consistent with the arc-shaped cavity in the end face of the nail bin in shape in a circular board, and nail abutting grooves matched with the nail outlet holes in position and shape are formed in the circular board around the cutting groove. After anastomosis, redundant esophageal and gastric tissues on the anterior wall deform into the stomach to form a tongue piece, and the tongue piece is matched with manual folding and suturing of the posterior wall in the gastral cavity to form a valvular tongue piece closing, so that a valvular structure is formed together. The anastomotic stoma channel is in a valvular closed state when no food is eaten, and the anastomotic stoma is opened due to the peristalsis pressure of the esophagus and the expansion effect of a food mass during eating, so that the effect of preventing stomach-esophageal reflux in a cardia shape is achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, more specifically, it relates to a novel esophagogastric asymmetric stapler with anti-reflux function. Background technique [0002] In medicine, a stapler is a device that replaces manual suturing. The main working principle is to separate and staple the tissue, similar to a stapler. For gastric cardia fundus and esophageal tumors, after surgical resection of the esophagus, cardia, or part of the gastric tissue at the tumor site, the healthy esophagus and stomach are connected with a stapler to restore the continuity of the digestive tract. At present, circular staplers or linear cutting staplers are commonly used clinically. After anastomosis, the esophagus and stomach are directly connected, and the anastomosis is continuously open, losing the "cardia"-like structure and anti-reflux function. Later, intractable reflux esophagitis occurred, which seriously affected the quality of life of the...

Problems solved by technology

At present, circular staplers or linear cutting staplers are commonly used clinically. After the anastomosis, the esophagus and stomach are directly connected, and the anastomosis is continuously open, losing the "cardia"-like structure and anti-reflux function. Refractory reflux esophagitis occurred later, seriously affecting the quality of life of the patient
