Abstract
The utility model discloses a temporary fixer for diaphyseal fracture of a lower limb. The temporary fixer comprises pincers parts, a clamping stop and handles. The temporary fixer is characterized in that: a 1/3 arc-shaped steel plate adapting to the length and the width of a human lower limb backbone is arranged at the end of the upper pincers part; two balls with pointed tops are arranged at the end of the lower pincers part; the upper pincers part, the lower pincers part, the 1/3 arc-shaped steel plate and the balls with the pointed tops surround a steel plate insertion position; the strip clamping stop is vertically arranged on the upper handle; and a clamping stop screw cap capable of moving along the clamping stop is arranged on the clamping stop. The temporary fixer solves the problem about temporary stabilization of two fractured ends in the steel plate placing process after the fracture is reset, reduces the operation time and the probability of injury and infection of soft tissues such as bone membranes and the like, and is suitable to be used in the diaphyseal fracture operation of the lower limb.
Description
Technical field
This utility model relates to field of medical appliances, is a kind of temporary fasteners that is used for the key fracture operation of lower limb specifically.
Technical background
The fracture temporary fasteners is an apparatus commonly used in the bone surgery, when fracture of the lower limb is carried out the steel plate internal fixation, need be after the reduction of the fracture with temporary fixed apparatus auxiliary fixing two broken ends of fractured bone of fracturing, fracture is stablized temporarily, so that place steel plate and be screwed into hold-down screw.But mostly present fracture temporary fasteners is two pawls or three-jaw bone holder, after the lower limb shaft fracture resets, need unclamp two pawls or three-jaw bone holder; Place steel plate again; Fracture displacement more easily particularly to unstable fracture, needs the repeatable operation reduction of the fracture and fixing like this in the middle of this process; Make troubles to operation, increased the probability of complication such as infection and bone does not connect.
The utility model content
This utility model provides a kind of lower limb shaft fracture temporary fasteners for solving the interim stable problem of two broken ends of fractured bone of in placing the steel plate process, fracturing after the reduction of the fracture in the Lower limb bone cadre operation.
The technical scheme of this utility model is; A kind of lower limb shaft fracture temporary fasteners; Comprise pincers portion, block, handle; Its special character is: the upper clamp part end is equipped with the 1/3 camber steel plate that all adapts with key length of human body lower limbs and width, and following pincers portion end is equipped with two top band point spheroids, and upper clamp part, pincers portion, 1/3 camber steel plate, top band point spheroid be around formation steel plate insert division down; The stripe shape block vertically is installed on the up knob, the block nut that can move along block is installed on the block.
During use, at first fracture is resetted, be clamped in fracture site with this holder then with reduction of the fracture pincers; 1/3 curved plate places key two broken ends of fractured bone top, and two top band point spheroids place fracture two broken ends of fractured bone below, clamp up knob and following handle; 1/3 curved plate can make fracture two broken ends of fractured bone stable, and top band point spheroid is little to soft tissue destruction, and fracture site upper and lower point, face combine; For fracture provides interim firm fixing, tighten the block nut, keep the accurate para-position of fracture site.Withdraw reduction forceps this moment, insert steel plate from the steel plate insert division, be screwed into screw and fix.Unclamp the block nut, withdraw this utility model.
Technique effect
The technique effect of this utility model is that it is a kind of simple in structure, easy to use, safe to adopt technique scheme to realize, can avoid fracture displacement repeatedly in placing the steel plate process in the art effectively, problems such as the difficult placement of steel plate.This temporary fasteners can shorten operating time, effectively avoids resetting repeatedly in the operation and waits operation, the probability of minimizing soft tissue and fracture site wound and infection.
Description of drawings
Fig. 1 is the structural front view of this utility model, and the accompanying drawing that makes an abstract.
In the drawings, 1,1/3 curved plate, 2, top band point spheroid, 3, the steel plate insert division, 4, the block nut, 5, up knob, 6, handle down, 7, upper clamp part, 8, pincers portion down, 9, block.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, this utility model is further specified.
As shown in the figure; Upper clamp part 7 ends are equipped with the 1/3 camber steel plate 1 that all adapts with key length of human body lower limbs and width; Following pincers portion 8 ends are equipped with two top band point spheroids 2; Upper clamp part 7, down pincers portion 8,1/3 camber steel plate 1, top band point spheroid 2 vertically are equipped with stripe shape block 9 around forming steel plate insert division 3 on the up knob 5, and the block nut 4 that can move along block is installed on the block 9.
During use, at first fracture is resetted, be clamped in fracture site with this holder then with reduction of the fracture pincers; 1/3 curved plate 1 evenly places shaft fracture two broken ends of fractured bone top, and two top band point spheroids 2 place fracture two broken ends of fractured bone below respectively, clamp up knob 5 and following handle 6; 1/3 curved plate 1 adds top band point spheroid 2, forms point, face combination at the fracture site upper and lower, for fracture provides interim firm fixing; Tighten block nut 4, keep fracture and continue accurate para-position.Withdraw reduction forceps this moment, and 3 insert steel plate from the steel plate insert division, are screwed into screw and fix.Unclamp block nut 4, withdraw this utility model.
