Background technology
Incidence of fracture is very high, and health and the living standard of the mankind in serious threat.Traditional Therapeutic Method has: (1) expectant treatment: by Gypsum Fibrosum, clamping plate or continuous traction or etc. treatment maintain the position of fracture end until union of fracture.(2) operative treatment: be generally internal fixation, to the cross-section folding of the patella that two sclerites are larger, conventional stainless steel silk is as inside-fixture.The defect of above Therapeutic Method easily produces multiple complications: (1) ankylosis suffering limb is fixed for a long time, vein and lymphatic return are not smooth, and in articular cavity, pulp fibers is oozed out and fibrin deposition, and fiber adhesion occurs, and with periarticular soft tissues contracture, cause joint movement disorder.(2) after the capable manual reduction plaster fixing of Gypsum Fibrosum compressing Fracture Simple, because limb swelling increases the weight of gradually, there will be Gypsum Fibrosum compressing, cause acrally occurring the situations such as obvious tumefaction, silt be blue or green, numb as the position such as finger, toe, medical institutions should be arrived in time and unclamp decompression, avoid limbs to oppress downright bad.(3) amyotrophy limbs are once fix or lack motion and amyotrophy will occur.
Summary of the invention
In order to solve in existing fractures method in technology arthrodesis mode, the problem of the various complication that the limbs one of fracture are stiff and cause, a kind of Combined type joint mobilizer of extenal fixation formula is provided, to a place or fracture fixation can be had more, the joint motion of the limbs of fracture can be realized again, avoid the generation of complication.
The technical solution used in the present invention is:
A kind of Combined type joint mobilizer, comprise two carbon fiber bars, multiple contiguous block and multiple folder needle assembly, the head of two carbon fiber bars is respectively connected with a contiguous block, connect through a screw between head two contiguous blocks of described two carbon fiber bars, the body of rod of two carbon fiber bars is also respectively arranged with more than one contiguous block, each contiguous block on the body of rod is all connected with more than one folder needle assembly, described folder needle assembly is connected with Kirschner wire.
Further, described contiguous block comprises the upper connecting rod folder, lower link folder and two clamp screw that are respectively arranged with two tapped through holes.
Further, described folder needle assembly comprises the upper clip and lower clamping piece that are respectively arranged with a through hole, and described upper and lower intermediate plate is installed on contiguous block through screw element.
Further, the circular arc type groove described upper and lower connecting rod folder is respectively arranged with.
Further, the circular arc type groove described upper and lower connecting rod folder surrounded is connected with carbon fiber bar.
Further, the upper and lower intermediate plate of described folder needle assembly is provided with circular arc type groove.
Again further, described upper and lower intermediate plate surrounds circular arc type groove and is connected with Kirschner wire.
The present invention takes the beneficial effect of above technical scheme to be:
1. the contiguous block of two carbon fiber club heads is connected in series through screw, in around screw 5 axially free rotary state or lock-out state between the first carbon fiber bar and the second carbon fiber bar, is association of activity and inertia, is convenient to the activity in joint, prevents the smooth or amyotrophy of blood circulation.
2. adopt Kirschner wire to thrust fixing from outside, minimally-invasive treatment is fractured, without the need to second operation, postoperative can movable joint, fracture more and after do not affect function of joint.
