Magnetic device provided with support for cholangio-jejunostomy and end-to-side intestinal anastomosis

Abstract

The invention discloses a magnetic device provided with a support for cholangio-jejunostomy and end-to-side intestinal anastomosis. The magnetic device uses magnetic attractions of more than two pairs of cholangio-jejunostomy devices and a pair of end-to-side intestinal anastomosis device and combines a polypropylene support to finish suture-free cholangio-jejunostomy and end-to-side intestinal anastomosis, so the magnetic device not only overcomes the defects of bile leakage, narrow anastomotic stomas and incomplete sutures frequently caused by the factors of irregular anastomotic stoma suture and the like, but also further ensures the safety of an operation because the used cholangio-jejunostomy devices and the end-to-side intestinal anastomosis device can be excreted to the outside of a body along with feces after a certain period of time and cannot remain in the human body to cause inconveniences and discomforts, and the adopted polypropylene support can prevent the bile leakage and intestinal fistula / leakage caused by the magnetic effect actuation among the components of the cholangio-jejunostomy devices and in the shedding and discharging processes of the components of the cholangio-jejunostomy devices and the end-to-side intestinal anastomosis device respectively.

Description

technical field [0001] The invention relates to a medical device, in particular to a magnetic device for end-to-side anastomosis of the liver, bile duct and jejunum with a bracket. Background technique [0002] High bile duct stenosis caused by various reasons is not uncommon in clinical practice. Due to the deep lesion and complex operation, after resection of the diseased tissue to reach the secondary hepatic bile duct, there are often as many as 4 to 8 bile duct stumps exposed in the operative field. Traditional hepatic duct plastic surgery and hepatic bile duct and jejunum suture anastomosis not only have extremely high requirements for the operator, are time-consuming and labor-intensive, but also often lead to high postoperative complications such as bile leakage and bile duct stenosis. Therefore, finding a convenient, feasible, and effective anastomosis method to improve the effect of hepatic cholangiojejunostomy is one of the clinical problems to be solved urgently. ...

AI Technical Summary

Problems solved by technology

However, up to now, there is no clinically available stapler for hepatic biliary jejunum reconstruction. The main reason is that the location of high bile duct stenosis is high, the lesion is complicated, and the design of the stapler is extremely difficult.
