Problems solved by technology

[0006] In the existing clinical practice, during the operation of removing stones from the bile duct, it is necessary to forcibly stretch the common bile duct sphincter for stone removal, which often causes destructive damage to the common bile duct sphincter, making its function invalid, unable to control the flow of bile, and Can not prevent the reflux of duodenal contents, causing postoperative pain for patients
Whether it is biliary tract exploration, using a biliary probe to pass through the sphincter of Oddis, or the most commonly used ERCP in gastroenterology and hepatobiliary surgery, it may cause dysfunction of the sphincter of Oddis. There is also no related device or device that can replace or partially replace the function of the Oddis sphincter, allowing the patient's bile duct to communicate with the duodenum for a long time, which will sell hidden dangers for future lesions

Abstract

The invention discloses an oddis sphincter bionic device, which comprises a bracket, a power assembly and a control assembly arranged outside the bracket, one end of the bracket is a valve part provided with a valve, and one side of the valve is a rotating shaft, which is rotated on On the valve part, one end of the bracket can be sealed or opened by opening or closing the valve; the power assembly includes a power source and a transmission mechanism, and the power source is connected to the valve through a transmission mechanism, and can drive The valve is opened or closed; the control assembly includes a controller and a wireless transmitter, and the controller is electrically connected to the wireless transmitter and the power source respectively. A technical effect of the present disclosure is that, when the present disclosure is installed in a human body, it can replace or partially replace the function of the oddis sphincter.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and more specifically relates to a bionic device for oddis sphincter. Background technique [0002] The human common bile duct runs to the posteromedial wall of the descending part of the duodenum, where it merges with the pancreatic duct into a slightly enlarged common duct called the ampulla of the hepatopancreas, which opens at the great papilla of the duodenum, where the sphincter is formed by It consists of three parts: the common bile duct sphincter, the pancreatic duct sphincter, and the ampulla sphincter, which together constitute the Oddis sphincter. Some people do not form a common duct without the ampullary sphincter. The sphincter of Oddis contains circular, longitudinal, and oblique smooth muscle fibers. No matter from the perspective of embryology, anatomy or physiology, the sphincter of Oddis is independent of the duodenum. [0003] Bile is secreted by the liver, trans...
