Abstract
The invention relates to a cable locking plate, in particular to an orthopedic internal fixing apparatus. An elongated block of the cable locking plate is provided with at least four screw holes passing inner and outer surfaces. At least one cable hole passing left and right sides of the block is formed between each two adjacent screw holes in the block. Through the cable holes in the cable locking plate, cable fixing traces are reduced and cable positioning is achieved; cable loosening after surgery is avoided, so that main sections on two sides of a fracture can more firmly fixed to the cable locking plate, and failure of internal fixation is prevented.
Description
Technical field
The present invention relates to a kind of orthopedics internal fixing appliance.Internal fixation apparatus especially for the treatment Periprosthetic fracture.
Background technology
When the treatment Periprosthetic fracture, at fracture site, use the lockplate (claiming again steel plate) of strip to connect the backbone of fracture both sides clinically at present.This lockplate is provided with at least four screw holes that run through the inside and outside surface of plate body, and several pieces of bone screw are locked, are fixed on the backbone of fracture both sides through screw hole corresponding on this lockplate respectively.Then use several cable that lockplate and backbone are stopped up, to being reinforced backbone and being connected of lockplate of fracture both sides.Due to many reasons, the postoperative phenomenon that easily occurs that cable is loosening, cause the constant intensity of the backbone of fracture both sides and lockplate inadequate, causes interior fixedly failure.
Summary of the invention
The present invention aims to provide a kind of cable lockplate, solves cable and becomes flexible and the inadequate difficult problem of constant intensity.
Technical scheme of the present invention is: the cable lockplate, and the plate body of strip is provided with at least four screw holes that run through inside and outside surface; At least be provided with the cable hole that laterally runs through together the plate body left and right side on plate body between every two adjacent screw holes.
During use, several pieces of bone screw are locked, are fixed on the backbone of fracture both sides through screw hole corresponding on this cable lockplate respectively.Then use several cable through cable hole corresponding on this cable lockplate, the backbone of this cable lockplate and fracture both sides to be stopped up respectively, to being reinforced backbone and being connected of cable lockplate of fracture both sides.Reduce cable fixedly incisura and cable positioning action because the cable hole on this cable lockplate has, postoperatively not there will be the loosening phenomenon of cable, thereby improved the backbone of fracture both sides and the constant intensity of cable lockplate, prevented interior fixing unsuccessfully.
Implement structure preferred: an end of described plate body is established bandy head and is formed two aduncate hooks at the free end of this head.This structure, can directly be connected this cable lockplate head portion point hook with the osteoarthrosis that prosthese is installed, fixing more firm.
In preferred enforcement structure: described head longitudinally axis has the Long Circle hole of running through inside and outside surface.Utilize the Long Circle hole to slacken the flexural strength of this cable locking wrench section, the doctor can carry out bending process to head in art, so that the head of this cable lockplate meets the surface of bone physiologic radian, closely reclines the femoral greater trochanter of prosthese is installed, reduce whole fixedly incisura.
In preferred enforcement structure: described head longitudinally axis is offered the guide pinhole that runs through the inside and outside surface of head between Long Circle hole and free end.The guide pin that the guide pinhole arranged like this makes the doctor to utilize and arranges in art is installed location to this cable lockplate, improves the quality of operation.
Particularly: the position in the corresponding Long Circle of described head hole at least is provided with the head cable hole that laterally runs through together the head left and right side.Utilize the head cable hole to wear cable and tie up this cable locking wrench section and the femoral greater trochanter that prosthese is installed, can effectively improve the femoral greater trochanter of installation prosthese and the constant intensity of this cable lockplate, improve whole stability.
Cable lockplate of the present invention, by cable hole reduce cable fixedly incisura and cable positioning action utilize cable to be fixed together lockplate and bone, form an integral body, prevent that cable is loosening, fracture end is formed strong fixing.Effectively solve cable and become flexible and inadequate this difficult problem of constant intensity, realized desirable fixing.
