Special dismountable ERCP multifunctional biliarystone removal saccule

Abstract

The invention provides a special dismountable ERCP (Endoscopic Retrograde Cholangiopancreatography) multifunctional biliarystone removal saccule, and relates to the technical field of a medical tool. The special dismountable ERCP multifunctional biliarystone removal saccule comprises a pipe body, a connector and a saccule, wherein a first saccule cavity, a first guide wire cavity and a first injection cavity are arranged in a first pipe fitting; a second saccule cavity, a second guide wire cavity and a second injection cavity are arranged in a second pipe fitting; a first connecting element is arranged at one end of the first pipe fitting; a second connecting element is arranged at one end of the second pipe fitting; a hollow saccule post, a hollow guide wire post and a hollow injection post are connected into the second connecting element; an air flow inlet and an air flow outlet are formed in the saccule post; a one-way valve is connected into the saccule post; the second connecting element and the first connecting element are detachably connected; and after the connection, the first saccule cavity, the first guide wire cavity and the first injection cavity are arranged in a way of being in one-to-one correspondence to the one-way valve, the guide wire post and the injection post. The special dismountable ERCP multifunctional biliarystone removal saccule has the stone removal function of an ordinary biliarystone removal saccule, and can also be used as a guide device; the ERCP operation risk is reduced; and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a detachable ERCP special-purpose multifunctional biliary stone removal balloon. Background technique [0002] Endoscopic retrograde cholangiopancreatography (ERCP) has become an important means of clinical diagnosis and treatment of biliary and pancreatic diseases. ERCP is to insert the duodenal endoscope into the descending part of the duodenum, find the main papilla of the duodenum (hereinafter referred to as the papilla), insert the contrast catheter from the biopsy hole to the opening of the papilla, and inject the contrast agent through X-ray fluoroscopy Or radiography to retrogradely display the angiography of the pancreaticobiliary duct. [0003] The stone removal balloon is a commonly used accessory device in the implementation of ERCP stone removal surgery. The stone extraction balloon is a catheter-shaped medical device, and the inflatable balloon is fixed...

AI Technical Summary

Problems solved by technology

Restricted by the direction of the duodenal papilla and the opening of the bile duct, direct transoral cholangioscopy is often difficult to insert into the bile duct, and it is impossible to visually observe the location, scope, nature, etc. of the lesion. The method of blind biopsy forceps is used to solve the problem, so the diagnosis and treatment efficiency of ERCP is low, and there is also a risk of perforation and bleeding when taking diseased tissue blindly
