Description

The miniature stones in intrahepatic bile duct dislodger of not damaged

This utility model belongs to the miniature stones in intrahepatic bile duct dislodger of not damaged of operation on biliary tract apparatus.

For a long time, retained calculus problem behind the operation on biliary tract is that surgeon is felt thorny thing always, because the stones in intrahepatic bile duct muddy stone is constantly sinked into common bile duct or left and right sides common hepatic duct, when surgeon clamps with general biliary tract stone extraction, think to exhaust the very difficult really thing of calculus as far as possible.Such as Chinese patent " laparoscopic surgery gall stone-removing clippers " (referring to calendar year 2001s 17 29 pages of No. 5, volumes), and " lithotomy forceps " (referring to 36 pages of No. 27,2000 16 volumes), though improve to some extent to getting stone structure, its effect of exhausting calculus is still satisfied inadequately.

The purpose of this utility model design, be to adopt silica gel catheter, the soft bar of rustless steel push-and-pull, rustless steel top guide and plastic handle, be designed to the novel miniature stones in intrahepatic bile duct dislodger of not damaged, make its flexible calculus of intrahepatic duct position of going deep into, promoting to get stone folder spoon by handle control stretches out to open and catches stone, or pulling is got stone folder spoon withdrawal and is closed the taking-up calculus, requirement can import left and right sides common hepatic duct safely or II-III level stones in intrahepatic bile duct is exhausted calculus, and have simple in structure, easy to use and do not damage the advantage of bile duct.

The technical essential of this utility model design: as shown in Figure 1,1) head is got stone structure and is got stone folder 1 by rustless steel top guide 2 cover card, and promotes to get stone folder 1 by the soft bar of push-and-pull (4,5) and stretch out, and opens stone taking-out spoon 9 and catches and make calculus, or pulling gets stone folder withdrawal, closes stone taking-out spoon and takes out calculus; 2) the flexible conduit structure by silica gel catheter 3 two ends respectively with top guide 2 right connectors and handle 10 left fitting sleeve stressed joints, interior pipe and the soft bar of push-and-pull (4,5) pine cover is connected, and makes conduit go deep into the gallbladder pipe agley with top guide; 3) the soft bar structure of push-and-pull is by stainless steel silk 4 outer casing stainless steel spiral silk braids 5, two ends are affixed mutually, and respectively with get stone and press from both sides 1 handle and pilot pin 7 covers and be solidly connected, can move forward and backward by sliding sleeve ring 6, promoting to get stone folder 1 stretches out or spur and get the stone folder and withdraw, and 4) the handle control structure is connected with handle 10 sliding sleeves by sliding sleeve ring 6, and move forward and backward along handle 10 guide grooves by pilot pin 7, driving the soft bar of push-and-pull (4,5) moves forward and backward, the controlled stone folder 1 of producing stretches out, open stone taking-out spoon 9 and catch and make calculus, or withdrawal is closed stone taking-out spoon 9 and taken out calculus.

Also in conjunction with the accompanying drawings project organization of the present utility model is described in detail as follows with embodiment below:

Fig. 1 is the structure chart of the miniature stones in intrahepatic bile duct dislodger of not damaged;

The location drawing that Fig. 2 is the miniature stones in intrahepatic bile duct dislodger of not damaged when getting stone folder spoon and close.

As Fig. 1, shown in 2, the miniature stones in intrahepatic bile duct dislodger of this not damaged is by rustless steel top guide 2, silica gel catheter 3, rustless steel is got stone folder 1, the soft bar (4 of rustless steel push-and-pull, 5), plastics sliding sleeve ring 6, rustless steel pilot pin 7 and plastic handle 10 are formed, it is characterized in that having 1 to tighten up with the level and smooth sleeve of conduit 3 left ends by top guide 2 right-hand member joints and to be connected, interior guide hole with get stone and press from both sides 1 handle pine cover and be connected, and press with the mouth part card and to be connected, left end lead ring hole is fit to stone taking-out spoon 9 and closes contact, get stone and press from both sides 1 right-hand member delthyrium and the soft bar (4 of push-and-pull, 5) left end passes and tightens up connection, and by the soft bar (4 of push-and-pull, 5) promoting to get stone folder 1 left stretches out, open stone taking-out spoon 9, or pulling to the right gets 1 withdrawal of stone folder, closes the head that stone taking-out spoon 9 forms and gets stone structure; 1 is tightened up with the level and smooth sleeve of top guide 2 right-hand member joints by silica gel catheter 3 left ends and to be connected, and right-hand member tightens up with handle 10 left end joint sleeves and is connected, and interior pipe is fit to the soft bar of push-and-pull (4,5) and passes the flexible conduit structure that loose sliding sleeve connects to form; 1 by stainless steel silk 4 outer casing stainless steel spiral silk braids 5, and steel wire about 4 ends are fixedlyed connected respectively with spiral silk braid about 5 ends, its left end is fit to pass to be got stone and presss from both sides 1 delthyrium and tighten up connection, right-hand member is fit to pass handle 10 endoporus and pilot pin 7 tightens up the soft bar structure of the push-and-pull that connects to form, and be connected with handle 10 sliding sleeves by sliding sleeve ring 6 endoporus, the collar tightens up with pilot pin 7 two ends sleeves and is connected, and by pilot pin 7 and the soft bar (4 of push-and-pull, 5) right-hand member tightens up connection, handle 10 left end joints tighten up with conduit 3 right-hand member sleeves and are connected, endoporus is fit to the soft bar (4 of push-and-pull, 5) right-hand member pine sliding sleeve passes, guide groove 8 is dynamically connected with pilot pin 7 slippages, pilot pin 7 is moved to the left with sliding sleeve ring 6, by the soft bar (4 of push-and-pull, 5) promote to get stone folder 1 and stretch out, open stone taking-out spoon 9, or the pulling that moves right gets 1 withdrawal of stone folder, closes the handle control structure that stone taking-out spoon 9 is formed.This utility model is got the miniature stones in intrahepatic bile duct dislodger of not damaged of stone structure, flexible conduit structure, the soft bar structure of push-and-pull and the combination of handle control structure by head, be fit to press top guide, the required external diameter size of conduit work, can make multiple model, its minor diameter is fit to children's or stones in intrahepatic bile duct is got calculus, and major diameter is fit to common bile duct or left and right sides common hepatic duct is got calculus.

In a word, the miniature stones in intrahepatic bile duct dislodger of not damaged that manufactures and designs according to present embodiment, the flexible stone location that gos deep into safely of its top guide and conduit, promoting to get the stone folder with the soft bar of handle control structure manipulation push-and-pull stretches out, opening stone taking-out spoon catches and makes calculus, or pulling gets stone folder withdrawal, closes stone taking-out spoon and takes out calculus.This utility model is simple in structure, and easy-to-operate can be exhausted the calculus that retains in biliary system, and don't the advantage of damage bile duct, is worth of widely use.
