Abstract

The invention discloses a multifunctional endoscope catheter. The multifunctional endoscope catheter comprises a first bending adjusting wheel connected with two first bending adjusting wires for adjusting a tail end of the catheter to be bent in a first direction; a second bending adjusting wheel connected with two second bending adjusting wires for adjusting a tail end of the catheter to be bent in a second direction, and an included angle is formed between the first direction and the second direction; a locking block capable of abutting against the first bending adjusting wheel and the second bending adjusting wheel and enabling the first bending adjusting wheel and the second bending adjusting wheel to be locked and fixed; and a pressing pop-up mechanism, after being pressed, the pressing pop-up mechanism can drive the locking block to be separated from contact surfaces of the first bending adjusting wheel and the second bending adjusting wheel. According to the multifunctional endoscope catheter, the first bending adjusting wheel and the second bending adjusting wheel are rapidly locked / unlocked in a mode that the pressing pop-up mechanism is connected with the locking block, and convenience of operating an endoscope by a doctor is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional endoscopic catheter. Background technique [0002] Endoscopic retrograde cholangiopancreatography is one of the main means of minimally invasive treatment of biliary and pancreatic diseases. The endoscope is inserted into the descending part of the duodenum through the mouth, and the special instrument is introduced into the bile duct or pancreatic duct through the duodenal papilla. (Encoscopic Retrograde Cholangio-Pancreatography, ERCP) under X-ray fluoroscopy, injection of contrast medium for imaging, introduction of sub-endoscope / ultrasound probe for observation, completes the diagnosis of biliary and pancreatic diseases. On the basis of ERCP, sphincterotomy (EST), endoscopic nasobiliary drainage (ENBD), endoscopic endobiliary drainage (ERBD), gallstone removal Interventional therapy such as pancreatic duct tumor stent drainage is very popular a...
