Abstract
The utility model discloses a proximal femur locking device, which comprises a proximal femur locking plate, locking screws and metal bone screws; two locking screw holes are formed in the proximal femur locking plate; the locking screws pass through the locking screw holes; two locking screws are used for fixing a femoral head in a transverse parallel and longitudinal crossing way; cap parts on the locking screws are provided with screw threads, and the screw threads are matched with the locking screw threads screwed into the locking screw holes; the rod parts of the locking screws are provided with external threads; the locking screws are used for fixing the femoral head through the external threads; and the metal bone screws are matched with the screw holes in the proximal femur locking plate, so that a femur rod is fixed by using a crossed structure. According to the proximal femur locking device, femoral neck fracture is effectively connected, and an anti-rotating effect is achieved, so that a proximal femur bone fracture plate system has the advantages of prevention of the ejection of the screws and prevention of the rotation of the femoral head; and moreover, the design is simple in structure, is easy for operating in surgery, and is safe and stable for use in clinic.
Description
Technical field
This utility model relates to the technical field of bone surgery set, is a kind of near end of thighbone locking device that utilizes the metal bone fracture plate fixed system to reset and fix specifically.
Background technology
Adopt clinically at present metal bone fracture plate fixed system-Lockplate for proximal end of femoral bones to reset, fix in for the bone surgery of fracture of femoral neck.The Lockplate for proximal end of femoral bones of prior art has a key position " screw hole ", and it plays the fixing metal bone screw in this retaining mechanism, relatively the effect of resected femur head.Existing screw hole and lock screw become space parallel after coordinating, lock under normal circumstances after lock screw and to guarantee again not allow the femoral head rotation when screw can resistance to plucking goes out, but two lock screw of space parallel be difficult to when being subject to the axial force repeated action assurance do not produce loosening, if after operation in rehabilitation training screw deviate from or the femoral head rotation can cause operative failure.The structure of therefore existing Lockplate for proximal end of femoral bones exists disadvantage in clinical use.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of near end of thighbone locking device that utilizes the metal bone fracture plate fixed system to reset and fix.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
Near end of thighbone locking device of the present utility model, comprise the Lockplate for proximal end of femoral bones, lock screw and the metal bone screw that are made of metal, lock screw and metal bone screw fix Lockplate for proximal end of femoral bones and femoral head and femur rod respectively, two screw hole are set on Lockplate for proximal end of femoral bones, lock screw is passed screw hole, and two lock screw are with the horizontal structure resected femur head of parallel, vertical intersection; On the pinning screw, cap section is provided with screw thread, and the locking screw that screws in screw hole matches, and the bar section of lock screw arranges external screw thread, and lock screw is by external screw thread resected femur head; Metal bone screw matches with screw hole on Lockplate for proximal end of femoral bones, with staggered structure resected femur bar.
This utility model can also adopt following technical measures:
The head of described Lockplate for proximal end of femoral bones arranges the guide pin locating hole, in the lower end of guide pin locating hole, cartilage pit is set.
The structure of location import tool is set on described screw hole.
Advantage and the good effect that the utlity model has are:
In near end of thighbone locking device of the present utility model, adopt laterally locking parallel, vertical cross modal to coordinate and effectively to connect the neck of femur fracture, and form anti-rotate effect, therefore near end of thighbone bone plate system of the present utility model has advantages of that anti-screw is deviate from, the rotation of anti-femoral head, and this project organization is simple, easy operating is arranged, clinical use safety and stability in operation.
