Description
Technical field
This utility model relates to a kind of orthopedic medical device bone fracture internal fixing device, is a kind of inside-fixture in the fractures, is used for the treatment of near end of thighbone, distal femur, tibial plateau and proximal humeral fracture.
Technical background
Though the internal fixation method of treatment bone fracture is a lot of at present, but there do not have a kind of method method that the coxa vara incidence rate of intertrochanteric fracture is reduced to be very low, also there is very high complication to take place after the existing inside-fixture treatment of supracondylar fracture of the femur, generally acknowledge the best hip power screw of effect both at home and abroad, its coxa vara and genu varum incidence rate are still 10 ‰～20 ‰, and this difficult problem is that existing inside-fixture is difficult to solve.
Summary of the invention
The purpose of this utility model is to solve in very difficult intertrochanteric fracture that solves of existing inside-fixture and the supracondylar fracture of the femur to turn over a difficult problem, and it is minimum that the wound that makes operation reaches, realize that the stability in the large behind Wicresoft's internal fixation is maximum, a kind of inner fixer that is used for the treatment of near end of thighbone, distal femur, tibial plateau and proximal humeral fracture is provided.
This utility model bone fracture internal fixing device content Description:
This utility model bone fracture internal fixing device, by: steel plate, self tapping spongy bone soket head cap screw, self tapping cortical bone soket head cap screw, the threaded broken cortical bone soket head cap screw of self tapping tail end, allen screw are formed, and it is characterized in that: the bone fracture internal fixing device overall structure is to constitute triangle combined crosswise or the three-dimensional interleave interlocking of antarafacial form by steel plate, self tapping spongy bone soket head cap screw, self tapping cortical bone soket head cap screw, the threaded broken cortical bone soket head cap screw combination of self tapping tail end back; Steel plate adopts parallel inclined hole steel plate, intersection inclined hole steel plate and snakehead inclined hole steel plate.
This utility model bone fracture internal fixing device can solve between the treatment rotor and supracondylar fracture of the femur a coxa vara and the domestic and international at present difficult problem that does not all have fine solution of genu varum occur because of device design defective postoperative.By nail needle plate triangle combined crosswise, the three-dimensional interleave of nail pin antarafacial, the interior heavy burden system that has rebuild femoral intertrochanteric and condyle of femur has improved stability in the large.Absorbed the advantage of hip power screw, overcome its shortcoming, the inclined hole steel plate promptly is the guider of nail pin, is again holder, guaranteed to thread a needle accurately, optimize nail pin steric configuration and fixing after stability.The utlity model has operation technique simple, can realize mini-incision insert, damage little, go out advantages such as insufficiency of blood, stability in the large are big, especially be fit between osteoporosis human femur rotor at advanced age, the internal fixation treatment of on the condyle of femur or lower end, tibial plateau, humerus lateral condyle neck fracture.
