Further, the universal ball structure includes spherical portion, third connecting portion, screw and nut；The spherical portionAnd the third connecting portion is fixed by the screw and nut connection；Second spherical of the spherical portion and instituteThe third spherical for stating third connecting portion is connected；The nut of the screw includes the 4th spherical, the 4th sphericalIt is connected with first spherical；The screw passes through the through-hole and the tapped through hole, and passes through the nutLocking.
Further, the second recess portion of the universal adjustable flipper guide be sliding guide groove, the second of second fixed partThe formation of connecting portion and second recess portion is slidably matched, the threaded portion of the soket head cap screw pass through second recess portion with it is describedThreaded hole is threadedly coupled, and the end of the threaded portion is inserted into the third recess portion；It is set on the nut of the soket head cap screwThere are symmetrical two semicircle orifices, two semicircle orifices are correspondingly arranged respectively with two pin holes, and two fixed pins are dividedIt is not inserted into the pin hole and the corresponding semicircle orifice.
Compared with the existing technology, the features of the present invention and progress are as follows：
1st, the first fixed part of osteotomy guide plate of the invention is connect with universal adjustable flipper guide by universal ball structure, can be made universalAdjustable flipper guide adjusts angle with respect to the first fixed part, by universal ball structure, can simply, conveniently, adjust osteotomy angle rapidlyDegree.
2nd, the second fixed part of osteotomy guide plate of the invention connect cooperation with universal adjustable flipper guide, forms adjustable slidingCooperation, the second fixed part are locked after being determined with universal adjustable flipper guide relative position by soket head cap screw, facilitate adjustmentThe relative position of universal adjustable flipper guide.
3rd, osteotomy guide plate of the invention reduces guide hole, and after determining osteotomy angle, the fixation that only needing 2 holes can stablize is cutBone conduction plate.
4th, osteotomy guide plate of the invention can be assisted using 3D printing bone model, and doctor can be with designed in advance operation plan, in advanceAngle is first set.
5th, osteotomy guide plate of the invention can obviously reduce operating time, reduces sufferer pain, reduces the generation of complications, contractShort average stay.
