Abstract

The invention discloses a gallbladder polypus cutter which is characterized by comprising a cylindrical outer sleeve pipe, an operating end, a limiting plate, a metal lead and a pair of V-shaped tongs; the operating end is installed on the limiting plate; the limiting plate is installed in a groove at the bottom end on the inner wall of the cylindrical outer sleeve pipe, and the limiting plate can move up and down or rotate in the groove; the metal lead is installed in the cylindrical outer sleeve pipe, one end is connected with the limiting plate, and the other end is connected with the pair of V-shaped tongs; the pair of V-shaped tongs is installed at the outer side of the cylindrical outer sleeve pipe, and the bottom of the pair of V-shaped tongs is connected with the metal lead; when the operating end is pulled, the limiting plate which is installed in the groove and connected with the operating end moves therewith, and the metal lead is driven to move; and while the metal lead moves, the pair of V-shaped tongs is driven to be retracted to the inside of the cylindrical outer sleeve pipe. Because the installation design of the limiting plate is adopted by the invention, the angles of the gallbladder polypus cutter can be freely adjusted for cutting the gallbladder polypus in an obstructed direction, and the gallbladder polypus cutter is convenient to clamp, thereby avoiding repeated adjustment.

Description

Gallbladder polypus cutter

Technical field

The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of device that is used for human gall bladder polypectomy or excising operation.

Background technology

It is optimum that cystic polyp mostly is greatly, ratio adenoma in the specimen of gallbladder removal has only 1.1%, and its rate of cancerating is 1.5%, be considered to the precancerous lesion of carcinoma of gallbladder, so cystic polyp is pernicious rarely found, and what take clinically at present is the gallbladder removal operation, is unscientific and all go gallbladder removal for benign pathological changes.Consider for the protection gallbladder function, avoid taking place the complication at a specified future date of postcholecystectomy, for the also not necessarily all capable cholecystectomy of processing of cystic polyp." scope Wicresoft protects gallbladder and gets polyp " method, its relapse rate only is 1%, under the direct-view of choledochoscope, extract in the breath in the art, at once send freezing pathological biopsy for contentious polyp, if the pernicious gallbladder removal of then going effects a radical cure, if the optimum gallbladder that then keeps has so avoided most benign polypus to be excised the misfortune of gallbladder.This method is that whether decision excises gallbladder according to the pathology character of cystic polyp, is considered to the Therapeutic Method of the most reasonable in clinical, the science of present biliary surgery.

At the existing apparatus that is used for this type of operation, biopsy forceps more commonly, biopsy forceps exist a lot of weak points in use with on the Clinical Application:

1, in extracting to cystic polyp, need adjust the position repeatedly, not only influence surgical field of view, the also artificial to a certain extent difficulty that grasps that increases;

2, in the process of carrying out polypectomy, need partly carry out long gripping to cystic polyp, after needing to wait for the blood coagulation of folded polyp part after the energising, just unclamp;

3, according to the difference of user body constitution, the process of after blood coagulation, unclamping, the hemorrhage situation of secondary can appear in the patient who has, and just need stop blooding again, has increased the time of operation;

Summary of the invention

The present invention is directed to the proposition of above problem, and develop a kind of new gallbladder polypus cutter, be intended to solve problems of the prior art.

Technical solution of the present invention is achieved in that

A kind of gallbladder polypus cutter, its feature comprises cylindrical jacket pipe, operating side, limiting plate, plain conductor, " V " clamp; Described operating side is installed on the limiting plate; Described limiting plate is installed in the groove of cylindrical jacket inside pipe wall bottom, and limiting plate can move up and down in groove or rotate; Described plain conductor is installed in the cylindrical jacket pipe, and an end is connected with limiting plate, and the other end is connected with " V " clamp; Described " V " clamp is installed in the cylindrical jacket pipe outside, and " V " clamp bottom is connected with plain conductor; The pull operation end is installed in the limiting plate that is connected with the operating side in the groove, movement therewith, and the drive plain conductor moves; In the plain conductor motion simultaneously, driving " V " clamp regains in the cylindrical jacket pipe.

Described cylindrical jacket pipe sidewall is equipped with the high frequency generator socket, and the high frequency generator socket is connected with plain conductor in the cylindrical jacket pipe by lead.

Described cylindrical jacket pipe lower end is the hard part, and front end is a soft section.

Described cylindrical jacket pipe lower end hard partly is equipped with Handleset.

Described " V " clamp can be completely integrated and take in the cylindrical jacket pipe after regain the operating side.

Because it is conspicuous having adopted above technical scheme advantage of the present invention:

1, the present invention adopts the clamp-type design, uses all available effective gripping in different affected parts;

2, the present invention adopts the installation design of limiting plate, can freely adjust angle on the cystic polyp that solves obstructed direction, makes things convenient for gripping, has avoided adjusting repeatedly;

3, the present invention is provided with circumscription socket, can be used with the high-frequency electronic generator, is issued to effect more easily in present medical condition;

4, the present invention utilizes the drawing and pulling type structure on operability, and is simple in the operation, saves operating time and increases work efficiency.
