The above purpose is realized by the following technical scheme:

a hepatobiliary surgery stone extraction device comprises: medical tweezers and tighten up the sleeve, medical tweezers's first half set up tighten up inside the sleeve, the branch mouth department of the lower half of medical tweezers set up and be in tighten up telescopic outside, medical tweezers's top about the junction welding of splint have the rectangular pipe, the terminal surface and the perpendicular fixed connection of fixed holding rod on top of rectangular pipe, the face of fixed holding rod on be provided with the otic placode, the otic placode with fixed holding rod structure as an organic whole, the otic placode on seted up the jack, and the interpolation has the optical axis in the jack, the both ends of optical axis rotate between being connected with left arc bull stick and right arc bull stick respectively.

Hepatobiliary surgery get stone device, left arc bull stick with the inboard of right arc bull stick pass through the connecting rod and connect perpendicularly, and will left arc bull stick with right arc bull stick be parallel structure, left arc bull stick with the tip processing of one side of right arc bull stick has the push pedal, just the push pedal on paste and have the one deck rubber pad, work as left arc bull stick with right arc bull stick pass through the optical axis when rotating, the push pedal on the rubber pad with tighten up the cambered surface contact at sleeve top.

The stone device is got in hepatobiliary surgery, the inboard welding of the left splint of medical tweezers and the right splint have the calculus splint of slice structure, just calculus splint on process and have the same tooth's socket of a set of structure, left arc bull stick with right arc bull stick rotate during the maximum distance, medical tweezers on left and right calculus splint closely laminate.

The length of the tightening sleeve is the same as that of the medical forceps, and the inner diameter of the tightening sleeve is larger than the thickness of the closed opening of the medical forceps and smaller than the maximum opening width of the medical forceps.

The utility model has the advantages that:

1. the utility model has simple structure and convenient operation, when clamping the calculus at the affected part of a patient, the left and right clamp plates on the disinfected medical tweezers are placed at two ends of the calculus to be taken out, then medical personnel hold the fixed holding rod, the left arc rotating rod and the right arc rotating rod with fingers, when holding the left arc rotating rod and the right arc rotating rod with fingers, because the left arc rotating rod is vertically connected with the right arc rotating rod by adopting a connecting rod, the left arc rotating rod and the right arc rotating rod rotate together through an optical axis, when the left arc rotating rod and the right arc rotating rod rotate clockwise, the push plates at the end parts of the left and right arc rotating rods rotate together with the arc rotating plates, when the push plates rotate, the push plates can push the tightening sleeve to move downwards, when the sleeve moves downwards, the barrel mouth at the bottom of the tightening sleeve can fold the left and right clamp plates of the medical tweezers, when the left and right clamp plates are folded, the calculus clamping plates on the left plate surface and the right plate surface of the medical forceps firmly clamp the calculus, and the calculus is taken out of the body of a patient to finish the calculus taking-out work.

2. The utility model discloses avoided traditional stone forceps getting when getting the calculus, it is too big to take place the action range, avoided causing the drawback of accidental injury to the human body when the calculus takes out, tighten up two splint of medical tweezers through tightening up the sleeve simultaneously, can make the calculus that takes out firmly the centre gripping between two splint, can not cause the calculus to drop from splint, this device adopts the mode of holding simultaneously, prevent to use medical tweezers to get the calculus in the past, need two fingers to nip in two splint of tweezers all the time, cause medical personnel's finger ache for a long time.
