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
The present invention relates to technical field of medical instruments, peep the incision knife device in a kind of ERCP of being applicable to intubate visual specifically.
Background technology
ERCP is namely through endoscopic retrograde cholangiopancreatography (Encoscopic Retrograde Cholangio-Pancreatography, ERCP) english abbreviation, under scope, to inject contrast agent through Duodenal papilla cannula, showing pancreaticobiliary shadowgraph technique thereby drive in the wrong direction, is the goldstandard of present diagnosis diseases of pancreaticobiliary duct of generally acknowledging.On the basis of ERCP, can carry out Internal biliary drainage (ERBD) under Endoscopic Sphincterotomy of Duodenal Papilla Attached art (EST), endoscopic bile drainage (ENBD), the scope, Extraction of Biliary Stones, the interventional therapys such as gallbladder ductus pancreaticus tumor stent drainage art, owing to not opening abdomen and Wicresoft, can greatly alleviate patient's misery and shorten the hospital stays.
Key also is that the most difficult technology is the intubate of selectivity bile duct or ductus pancreaticus in the ERCP operation, because if intubate is unsuccessful, follow-up diagnosis and treatment also just can't be carried out.By the improvement of maneuver and the progress of apparatus, the success rate of selectivity gallbladder pancreatic canula is significantly improved, but still lower through the success rate after the improvement, and the incidence rate of complication is also higher.
Conventional gallbladder pancreatic canula adopts the auxiliary pull-type incision knife intubation of seal wire, namely through the duodenoscope accessory passageway, will be with the shallow insertion vater's papilla of the pull-type incision knife opening of hydrophilic superslide seal wire, after under X-ray examination, using the seal wire selectivity to detect bile duct or the success of ductus pancreaticus opening, again incision knife is inserted bile duct or ductus pancreaticus along seal wire.The problem that the method exists is:
1, operation doctor and patient is exposed under the roentgen radiation x for a long time, has a harmful effect to healthy;
2, when intubate, can only the rough alignment bile duct or the direction of ductus pancreaticus (be respectively 11 o'clock and 1 o'clock direction) blindmate, accurate intubate and may damage nipple, bile duct or ductus pancreaticus;
If 3 intubate are unsuccessful, can't judge accurately its concrete reason.
The super choosing of the seal wire at the selective catheterizaiton of selectivity left and right sides common hepatic duct and branch thereof and bile duct stricture of pancreatic duct position is another difficult problem among the ERCP.Conventional method also is to adopt the super choosing of the auxiliary seal wire of the auxiliary pull-type incision knife of seal wire, and therefore above-mentioned problem exists equally.
Summary of the invention
The purpose of this invention is to provide and a kind ofly peep the incision knife device in visual, this device can enter human body by the duodenoscope biopsy channel, can under the direct-view state, seek the opening of opening, left and right sides common hepatic duct and branch thereof of bile duct ductus pancreaticus and the opening of narrow positions, and can carry out conventional Sphincterotomy operation, realize the lower selective catheterizaiton of direct-view.
The present invention is a kind of to peep the incision knife device in visual, comprise incision knife 3, be set as in also comprising picture objective lens unit 2 and optical fiber image transmission beam 4 hard tube 1, be used for receiving optical fiber image transmission beam 4 catoptrical eyepieces 5, be used for gathering and ccd image sensor (Charged Coupled Device) 6 and the electronic computer terminal 7 of the optical signalling that conversion eyepiece 5 focuses on, described incision knife 3 is arranged on nearly image-forming objective lens assembly 2 one ends on the hard tube 1, and described eyepiece 5 is arranged on fine coherent fiber bundle 4 one ends of hard tube 1 outside dipped beam.
Described image-forming objective lens assembly 2 comprises concavees lens 8 and the convex lens 9 that sets gradually, and described concavees lens 8 are arranged near the object end, and convex lens 9 is arranged on thing end far away.
Described image-forming objective lens assembly 2 length are 3-5mm, and the angle of visual field is 40 °-60 °.
The external diameter of described concavees lens 8 and convex lens 9 is 0.6-0.8mm.
Described hard tube 1 external diameter is less than 1mm, and length is less than 10mm.
Described optical fiber image transmission beam 4 external diameters are 0.6-0.8mm.
Peeping the incision knife device in the present invention is visual is achieved in that and will peeps the incision knife device in visual by arrival duodenum top, duodenoscope biopsy hole, focus on optical fiber image transmission beam 4 end faces from the light of object observing 12 surface reflections through based endoscopic imaging objective lens unit 2, optical fiber image transmission beam 4 transfers to eyepiece 5 with reflected light, eyepiece 5 focuses on ccd image sensor 6 surfaces with optical signalling, gather optical signalling with ccd image sensor 6, and transfer optical signal to the signal of telecommunication, process and show by electronic computer terminal 7.
The advantage of peeping the incision knife device in the present invention is visual is: can carry out the ERCP intubate under the direct-view state, can differentiate ductus pancreaticus and bile duct by observing image, therefore can reduce operation doctor and patient and be exposed to time under the X ray, can improve simultaneously the success rate of selective catheterizaiton, reduce simultaneously the generation of some complication.
