Background technology
The homemade fiber endoscopy of present clinical use and the fibrescope choledochoscope of import; Be mainly used in and detect biliary tract in the art; To be diagnosed as the master; Extrahepatic bile ducts calculus and part I and II calculus of bile duct are had therapeutical effect, but it is low to get stone efficient, and to diagnosis of the hepatobiliary calculus below the diameter 4mm and treatment difficulty.Basket is got stone the lower common bile duct calculous obstruction is got the stone difficulty under the choledochoscope in addition.Calculous obstruction and reservation gallbladder take out the weak curative effect of calculus in the gallbladder under clinical treatment stones in intrahepatic bile duct, the common bile duct at present, and remnant gallstone rate is high, and operability is high once more.
Summary of the invention
Main purpose of the present invention is to overcome the shortcoming of prior art; A kind of biliary tract stone extraction mirror is provided, and efficiently the calculus of one, two, three bile duct of fast processing even part level Four calculus of bile duct and common bile duct (hypomere especially), reservation gallbladder take out calculus in the gallbladder.
The present invention adopts following technical scheme:
The biliary tract stone extraction mirror; Comprise a shank; First end of this shank forms the mirror point; Second end of this shank is connected with cold light source interface, water inlet interface, utilizing camera interface and operating walk way inlet, and the rear portion of this shank is the cavity structure, and this cavity structure is communicated with this cold light source interface, water inlet interface, utilizing camera interface and operating walk way inlet.
Preferably, said operating walk way inlet is on the same straight line with said cavity structure.
Preferably, said utilizing camera interface and said shank have an angle, 120 °＜this angle＜160 °.
Preferably, also include the water outlet interface.
Preferably, said shank is tapered from its rear portion to its mirror point.
Preferably, the external diameter of said mirror point is 2-4mm.
Preferably, second end of said shank also is provided with a finger fixed handle.
Preferably, said shank front end is arc-shaped bend to the left or to the right, and angle of bend is 10-25 °; Promptly the length of inlet is 35-45cm to said shank from the mirror point to operating walk way.
Preferably, promptly the total length of inlet is 45-62cm to said shank from the mirror point to operating walk way, and this shank has certain suppleness, can realize 10-15 ° bending.
Can know by the above-mentioned description of this invention; Compared with prior art; Biliary tract stone extraction mirror of the present invention connects photographic head by utilizing camera interface; Can be efficient down in the direct-view of TV or computer screen, the calculus in one, two, three bile duct of fast processing even part level Four calculus of bile duct, common bile duct (hypomere especially in) and the reservation gallbladder taking-up gallbladder, get stone efficient height; Secondly, have utilizing camera interface and can under TV or computer screen, know the demonstration stones in intrahepatic bile duct, make that to get stone simple to operate; The 3rd; Be provided with the operating walk way inlet; Lithotomy forceps presss from both sides calculus through this operating walk way inlet clamp calculus or with pliers that broken (most of hepatic calculus are soft; Clamp is broken easily), the calculus harder or bigger to quality can smash calculus through this operating walk way inlet through rock crushing plants such as pneumatic ballistic lithotripsy bar, ultrasonic rubble bars; The 4th, be provided with into water interface,, equipment such as hydraulic pressure charge pump pass through this passage under assisting; With having pressed from both sides broken calculus in the hepatic duct or the microlith water washes out; Perhaps will press from both sides broken calculus sucking-off through the water outlet interface, and have rubble, get stone and carry out synchronously, high efficiency is taken out the function of calculus; The shank front end can be convexly curved, and perhaps shank has certain suppleness, to biliary tract variation calculus, complicated better the handling of gallbladder tube structure, makes biliary tract stone extraction mirror of the present invention have wide range of applications; The 5th, the present invention is simple in structure, and the sterilization of several different methods such as available high temperature or medicining liquid dipping is durable in use.
