Visualization endoscopic incision knife device

Abstract

The invention discloses a visualization endoscopic incision knife device which comprises an incision knife (3), further comprises a hard tube (1) which is internally provided with an imaging objective lens component (2) and an optical fiber image transmission beam (4), an eye lens (5) for receiving the reflected light of the optical fiber image transmission beam (4), a charge coupled device (CCD) image sensor (6) for acquiring and converting an optical signal focused by the eye lens (5), and an electronic computer terminal (7), wherein the incision knife (3) is arranged at one end of the hard tube (1) near the imaging objective lens component (2); and the eye lens (5) is arranged at one end outside the hard tube (1) near the optical fiber image transmission beam (4). The visualization endoscopic incision knife device has the advantages that endoscopic retrograde cholangiopancreatography (ERCP) intubation can be carried out at a visual state, and the pancreatic duct and the bile duct can be distinguished by observing the image, so that the time that doctors and patients are exposed to the X-ray is reduced; and meanwhile the success rate in selective intubation is improved, and the happening of complications is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a visual endotomy knife device suitable for ERCP intubation. Background technique [0002] ERCP is the abbreviation of Encoscopic Retrograde Cholangio-Pancreatography (ERCP). Currently recognized as the gold standard for the diagnosis of pancreaticobiliary disease. On the basis of ERCP, sphincterotomy (EST), endoscopic nasobiliary drainage (ENBD), endoscopic endobiliary drainage (ERBD), common bile duct stone removal, bile duct and pancreas can be performed. Interventional treatment such as tube tumor stent drainage can greatly reduce the suffering of patients and shorten the length of hospital stay because it does not require laparotomy and is minimally invasive. [0003] The key and the most difficult technique in ERCP operation is the selective intubation of the bile duct or pancreatic duct, because if the intubation is unsuccessful, subsequent diagnosis and trea...

AI Technical Summary

Problems solved by technology

[0005] 1. The operator and the patient are exposed to X-ray radiation for a long time, which will have adverse effects on their health;

[0006] 2. When intubating, it can only be inserted roughly in the direction of the bile duct or pancreatic duct (11 o’clock and 1 o’clock directions respectively), and can not be accurately intubated and may damage the nipple, bile duct or pancreatic duct;

[0007] 3. If the intubation is unsuccessful, the specific reason cannot be accurately judged

The conventional method is also to use the guide wire to assist the pull-type incision knife to assist the guide wire superselection, so the above-mentioned problems also exist.
