Content of the invention
In order to solve in technology in existing fractures method to arthrodesis mode, the problem of the various complication that the limbs of fracture one are stiff and lead to, a kind of outer fixed Combined type joint mobilizer is provided, can be at one or have more fracture fixation, the joint motion of the limbs of fracture can be realized, it is to avoid the generation of complication again.
The technical solution used in the present invention is：
A kind of Combined type joint mobilizer, including 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, through a mode connects for screw between two contiguous blocks of the head of described two carbon fiber bars, more than one contiguous block is also respectively provided with the body of rod of two carbon fiber bars, more than one folder needle assembly is respectively connected with each contiguous block on the body of rod, described folder needle assembly is connected with Kirschner wire.
Further, described contiguous block includes upper connecting rod folder, lower link folder and two clamp screw being respectively arranged with two tapped through holes.
Further, described folder needle assembly includes upper clip and the lower clamping piece being 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 being respectively arranged with.
Further, the circular arc type groove described upper and lower connecting rod folder surrounding 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.
Yet further, described upper and lower intermediate plate is surrounded circular arc type groove and is connected with Kirschner wire.
The present invention takes having the beneficial effect that of above technical scheme：
1. the contiguous block of two carbon fiber club heads concatenates through screw, is in around the axially free rotary state of screw 5 or lock-out state, is association of activity and inertia, is easy to the activity in joint between the first carbon fiber bar and the second carbon fiber bar, prevents blood circulation not smooth or amyotrophy.
2. adopt Kirschner wire to fix from outside piercing, minimally-invasive treatment is fractured, without second operation, postoperative can with movable joint, fracture more and after do not affect function of joint.
