Abstract
The utility model relates to a direct vision biliary tract lithotomy forceps used for biliary tract stone removal (gall stone) in a human body and belongs to the field of medical devices. The direct vision biliary tract lithotomy forceps comprise a fixed handle, a movable handle, a forceps rod, a forceps holder base, a pull rod, a connecting plate, forceps holders, a rotating wheel, a ball sleeve, a connecting sleeve and a rotating wheel sleeve. One end of the forceps rod at which the forceps holder base is fixed is bent; and an arc-shaped groove is formed on each forceps holder. Because one end of the forceps rod is bent, and the arc-shaped groove is formed on each forceps holder, a bent forceps head has convenient application in the biliary tract stone removal operation; the arc-shaped groove closed on each forceps holder is in the shape of an arc-shaped body and has a compact structure; and the lithotomy forceps absolutely can not randomly fall off in the arc-shaped body.
Description
Technical field
This utility model relates to a kind of direct-view biliary tract stone extraction pincers, is used for biliary tract stone extraction (cholelithiasis) in the human body, belongs to medical instruments field.
Background technology
In the human body body, in the laparoscopic surgery, under the laparoscopically visual field, need carry out biliary tract stone extraction to the cholelithiasis disease.Prior art is with common nipper, carrying out of separating is pressed from both sides out after the gripping external, and its defective is: common nipper is difficult to enter biliary tract, at gripping process and the middle calculus utmost point to come off, the gripping instability, it is slow to get stone speed, does not satisfy ideal surgical effect.
The utility model content
The technical problems to be solved in the utility model overcomes above shortcomings in the existing structure exactly, and provides a kind of reasonable in design, operation to use convenient, effective, safe direct-view biliary tract stone extraction pincers.
The technical scheme in the invention for solving the above technical problem is: a kind of direct-view biliary tract stone extraction pincers comprise fixed handle, flexible handle, claw beam, clamp seat, pull bar, connecting plate, clamp, runner, ball cover, adapter sleeve and rotaring wheeling sleeve; Fixed handle and flexible handle are rotationally connected; The clamp seat is fixed on the claw beam; Connecting plate is rotatably connected on the clamp seat; Clamp is fixed on the connecting plate; Pull bar one end is rotatably connected on the connecting plate, and the other end is connected on the flexible handle; Adapter sleeve is fixed on the fixed handle; Rotaring wheeling sleeve is fixedlyed connected with claw beam with runner respectively; The ball cover is sleeved on outside the rotaring wheeling sleeve, and is fixed on the adapter sleeve; It is characterized in that: the end that described claw beam is fixed with the clamp seat is bending; Have arcuate groove on the described clamp.
Pull bar one end described in the utility model is fixed with spheric draw-bar seat, and described pull bar is connected on the flexible handle by draw-bar seat.
This utility model compared with prior art has following advantage and effect: 1, reasonable in design; 2, an end of claw beam is bending, and the clamp design has arcuate groove; In the biliary tract stone extraction operation, sweeping binding clip is used convenient; Clamp folder close the curved body of arcuate groove and structure tight, calculus is clipped in the arc body and can never arbitrarily comes off.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
The specific embodiment
