Description
Technical field
This utility model belongs to medical instruments field, is specifically related to one slidably clipping fracture fixation guider.
Background technology
Two parts fracture relating to articular surface in clinical is comparatively common, as fracture of the tibial plateau, fracture of femoral condyle, fracture of humeral condyle and carpal fracture of the scaphoid bone etc., principle for this type of fractures two parts fracture first need be converted into part fracture, at present fixing means mostly clinically is blind under X-ray examination and wears Kirschner wire, through repeatedly confirming that Kirschner wire position pierces cannulated compression screw along Kirschner wire again and gives fracture end and fix after satisfied.Mainly there are two large technical problems in it: one is for different parts, dissimilar fracture, the needle track of selected Kirschner wire is difficult to accurate location, X-ray examination repeatedly certainly will add the ray exposed amount of medical worker, and destructible sclerotin and affect the fixing fixing of fracture end; Two is current conventional towel forceps clamp fracture line two ends clinically, because jaw span is limited and be endless clamp, and may form interference to Kirschner wire entry point and exit points, therefore to maintenance after bone block reset and thread a needle and fixedly bring larger difficulty.
Utility model content
For the technical problem that background technology proposes, this utility model provides one slidably clipping fracture fixation guider, for solving the problem.
The purpose of this utility model can be achieved through the following technical solutions:
One is clipping fracture fixation guider slidably, it comprises arc fixed handle and is located at the first fixed muffle and second fixed muffle at described arc fixed handle two ends respectively, the the first slidably pilot sleeve matched with it is provided with in the first described fixed muffle, be provided with the second slidably pilot sleeve matched with it in the second described fixed muffle, inside described arc fixed handle, be provided with tie-strut.This tie-strut is fixed in fractured bones process at both sides slide-and-guide sleeve clamping, prevents the distortion of described arc fixed handle and arc fixed handle two ends fixed muffle to be subjected to displacement.
Screw thread is equipped with inside described first fixed muffle and the second fixed muffle, the outer surface of the described first slidably pilot sleeve and second slidably pilot sleeve is provided with screw thread, be located at screw thread inside the first fixed muffle and the second fixed muffle to match with the screw thread being located at the first slidably pilot sleeve and second slidably guiding sleeve outer surface respectively, by rotating the first slidably pilot sleeve and second slidably pilot sleeve, the adjustment first slidably distance of pilot sleeve and second slidably between pilot sleeve.Be convenient to the fixing of dissimilar, different parts two parts fracture.
The afterbody of the described first slidably pilot sleeve and second slidably pilot sleeve is zigzag.One is contribute to the accurate location to Kirschner wire entry point, exit points and nail road; Two is form strong occlusion and stable fixation by the sawtooth of its afterbody to bone surface.
The internal diameter of the described first slidably pilot sleeve and second slidably pilot sleeve is 2 ~ 4mm, and external diameter is 4 ~ 6mm, and length is 20 ~ 40mm.
The internal diameter of described first fixed muffle and the second fixed muffle is 4 ~ 6mm, and external diameter is 6 ~ 8mm, and length is 10mm.
Spacing (W value) between described first fixed muffle and the second fixed muffle is 40 ~ 60mm.
The beneficial effects of the utility model:
Designed by said structure, the slidably clipping fracture fixation guider of this utility model design has following construction features: be equipped with screw thread inside described first fixed muffle and the second fixed muffle, the outer surface of the described first slidably pilot sleeve and the second movable pilot sleeve is provided with the screw thread matched with it, can free adjustment in fixed muffle by slidably sleeve, coordinate the slide-and-guide sleeve of different length simultaneously, be convenient to its use in Different Diameter long bone block is fixed, and certain pressurization can be played to the bone block end resetted.The afterbody of the described first slidably pilot sleeve and second slidably pilot sleeve is zigzag, zigzag being designed with helps form strong occlusion to bone surface, play anti-skidding effect, improve the slidably clipping structural compatibility of fracture fixation guider use and the stability of use dramatically; A tie-strut is designed with inside described arc fixed handle near-end, fix in bone block process at both sides slide-and-guide sleeve clamping, effectively prevent the elastic deformation of described arc fixed handle and the risk of arc fixed handle far-end both sides fixed muffle generation skew.According to different parts fracture and the direction of different fracture line, fixed muffle can be utilized as required to determine Kirschner wire entry point and the exit points of two side seam block end cortex surface, slidably clipping fracture fixation guide structure is simple, easy to use, quick, fracture fixation is firm for this, x-ray exposed amount in art can be reduced, effectively prevent the generation of the complication such as postoperative fixation failure, the loss that resets.

Detailed description of the invention
As shown in Figure 1 and Figure 2, one is clipping fracture fixation guider slidably, it comprises arc fixed handle 1 and is located at the first fixed muffle 2-1 and the second fixed muffle 2-2 at described arc fixed handle 1 two ends respectively, the the first slidably pilot sleeve 4-1 matched with it is provided with in the first described fixed muffle 2-1, be provided with the second slidably pilot sleeve 4-2 matched with it in the second described fixed muffle 2-2, inside described arc fixed handle 1, be provided with tie-strut 3.
Screw thread is equipped with inside described first fixed muffle 2-1 and the second fixed muffle 2-2, the outer surface of the described first slidably pilot sleeve 4-1 and second slidably pilot sleeve 4-2 is provided with screw thread, be located at screw thread inside the first fixed muffle 2-1 and the second fixed muffle 2-2 to match with the screw thread being located at the first slidably pilot sleeve 4-1 and second slidably pilot sleeve 4-2 outer surface respectively, by rotating the first slidably pilot sleeve 4-1 and second slidably pilot sleeve 4-2, the adjustment first slidably distance of pilot sleeve 4-1 and second slidably between pilot sleeve 4-2.
The afterbody of the described first slidably pilot sleeve 4-1 and second slidably pilot sleeve 4-2 is zigzag.
The internal diameter of the described first slidably pilot sleeve 4-1 and second slidably pilot sleeve 4-2 is 2 ~ 4mm, and external diameter is 4 ~ 6mm, and length is 20 ~ 40mm.
The internal diameter of described first fixed muffle 2-1 and the second fixed muffle 2-2 is 4 ~ 6mm, and external diameter is 6 ~ 8mm, and length is 10mm.
