With the crotch front end of cross tube point-blank, the other end of sheer pole is vertical with the lower end of pilot sleeve to be fixedly connected, gram
Family name's pin passes through pilot hole, and the front end of Kirschner wire is relative with the crotch front end center of cross tube, and pilot sleeve is square tube sleeve, is oriented to
The body of rod section of bar is rectangle, and behind the body of rod of guide post and two sides are slip with pilot sleeve inner chamber rear wall and two side
Contact, is longitudinal tooth bar before the body of rod of guide post, gear be arranged on before the body of rod of guide post with before pilot sleeve inner chamber
In gap between wall, gear is meshed with the tooth bar before the body of rod of guide post, gear shaft through pilot sleeve side wall with
Rotate handle coaxially connected.
Above-mentioned orthopaedics Minimally Invasive Surgery guider, the sophisticated end face of the cross tube leading hook has blind hole, in blind hole
The center line at heart line and crotch tip overlaps, the external diameter phase of aperture of the blind hole at crotch tip inlets and Kirschner wire front end
Match somebody with somebody, the front end of blind hole is sharp.
Above-mentioned orthopaedics Minimally Invasive Surgery guider, is provided with sleeve pipe at the pilot hole of the sheer pole, sleeve pipe has multiple, many
The external diameter of individual sleeve pipe matches with the internal diameter of pilot hole, the internal diameter of multiple sleeve pipes respectively with the external diameter of the Kirschner wire of various outer diameter
Match, there is screw thread on the inwall of the pilot hole of sheer pole, have screw thread on the outer wall of multiple sleeve pipes respectively with pilot hole inwall
Screw thread matches.
Above-mentioned orthopaedics Minimally Invasive Surgery guider, is set with ratchet, the fairlead of ratchet side in the rotation Handle axis
Ratchet is installed on the outer wall of cylinder, ratchet is meshed with ratchet.
The invention has the beneficial effects as follows：
The Kirschner wire of the present invention can be oriented to by the pilot hole of the crotch of cross tube and sheer pole, and guide post can be along
Guide thimble is moved, and the distance between cross tube adjustment and sheer pole is driven, so as to the bone piece between cross tube and sheer pole
Pressure.Clinical efficacy of the present invention is definite, and quickly control is difficult the bone piece tissue for clamping can to help patient, substantially reduces operation
Time, the radiation of x-ray is reduced, reduce operation wound, while guaranteeing well to reset, healing for fracture is realized to a greater extent
Close.Fix, the squeezing into of elbow joint deformity osteotomy lag screw, the fixation of fracture of ulna coronoid process, close fracture of wing of ilium is implemented
Section around inside-fixture insert wait operation in more uniqueness convenient part.
The present invention is pioneering in orthopaedics Minimally Invasive Surgery, solves some positions in orthopaedics Minimally Invasive Surgery and is difficult to be accurately positioned
Problem, be particularly conducive to help patient that quickly control is difficult the bone piece tissue for clamping, to shorten operating time and reduce x-ray spoke
Penetrate the injury to human body, it is ensured that operation is smoothed out.
