Description
Technical field
The present invention relates to technical field of medical instrument, specially a kind of rotary type biliary tract curet.
Background technique
Hepatology doctor is usually scraped the sundries such as calculus in biliary tract using biliary tract curet when treating gall stone,
However existing biliary tract curet design is simply, head is only spoon shape mostly, very not square for directly digging calculus in biliary tract
Just, cricoid biliary tract scrapes key bit and is difficult to dig out calculus into biliary tract, and doctor, which uses, to be inconvenient.
Set forth above in order to solve the problems, such as, in the prior art, application No. is a kind of biliary tracts of " 201720236834.1 "
Curet is related to medical instruments field, and the grip ring side of the biliary tract curet is equipped with two thin connecting rods in 60 ° of angles, two thin connecting rods
Angle is moderate, and work phase is not interfere with each other, wherein one thin interlinking lever end is equipped with cricoid scraping ring, another thin interlinking lever end is set
There is the spatula of hemisphere shell sape, use Shi doctor that can hold grip ring, calculus in biliary tract is first drawn into loosening using scraping ring, recycles spatula
Calculus is dug out, no replacement is required in course of work instrument is easy to operate, improves gall stone procedure efficiency.
But the above-mentioned biliary tract curet is in use, however it remains following more apparent defect: 1, thin connecting rod angle
Degree is fixed, and for various sizes of biliary tract, can not realize compatibility well；2, by the cooperation of spatula and scraping ring, although can
Calculus to be dug out, but every time scraping ring loosen calculus after, it is necessary to calculus is dug out using spatula at once, it is duplicate protrude into and
Curet is taken out, operate cumbersome and removes calculus inefficiency.
Summary of the invention
The purpose of the present invention is to provide a kind of rotary type biliary tract curets, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the invention provides the following technical scheme:

It is twined on the power wheel equipped with connecting rope, the connecting rope is flexibly connected with depending post.
Preferably, more scraping rings are provided between single scraping ring, more scraping rings are fixed in shaft, and more scraping rings include short
Bar and multiple ring bodies are fixedly connected between the ring body by quarter butt.
Preferably, rope groove is offered on the depending post.
Preferably, the rod surface opens up fluted, and crushing block is symmetrically arranged in the groove, and the crushing block is logical
Spring to be crossed to be connected in recess sidewall, the groove bottom wall offers vertical core between crushing block, and the vertical core is connected with cross-drilled hole,
Limit rope is movably set in the cross-drilled hole, the limit rope is fixed on the connecting rod of the other side far from cross-drilled hole one end.
Compared with prior art, the beneficial effects of the present invention are:
1, for the present invention by the setting of crushing block in groove, the length of adjustable limit rope, which is simultaneously clamped, realizes fixation, from
And the angle between two connecting rods of adjustment is played, to realize preferably compatibility；
2, after curet of the invention protrudes into biliary tract, single scraping ring and more scraping rings is driven to be rotated by shaft, to play
The effect for loosening and carrying calculus, it is intracavitary to be transferred directly to calculus for calculus, it is no longer necessary to and the switching of scraping ring and spatula uses,
It no longer needs to repeat the taking-up of curet and protrudes into, substantially increase the efficiency for removing calculus.
The length of the adjustable limit rope of the present invention simultaneously clamps realization fixation, to play the angle between two connecting rods of adjustment
Degree realizes preferably compatibility, also no longer needs to repeat the taking-up of curet and protrude into, substantially increases the effect for removing calculus
Rate, easy to operate, practicability is very strong, highly promotes.
