Abstract
The utility model provides a thighbone locking plate which comprises a locking plate body. The two ends of the thighbone locking plate are the triangle-like ends. The two ends of the thighbone locking plate are provided with locating holes. The thighbone locking plate is provided with a locking hole and a locking and pressurizing combined hole in the axial direction. The locking hole and the locking and pressurizing combined hole are symmetrically distributed in a left-right mode. One side of the thighbone locking plate is provided with a pressure reduction groove. The thighbone locking plate has the advantages of being capable of resisting the strong shearing force and pressurizing broken bones, fixing the broken bones firmly, and quickening healing of the broken bones. Moreover, the shape design is suitable for the minimally invasive surgery, and therefore the surgical wound surface of patients can be reduced. Pressure on periosteum from the thighbone locking plate is reduced, influence on blood supply to the broken bones is reduced, and the broken bones can be healed fast.
Description
Technical field
This utility model belongs to medical instruments field, especially relates to a kind of femur lockplate.
Background technology
In bone surgery, need to utilize femur lockplate and screw to implement fracture site fixing, there is following technical problem in present femur lockplate: oppress periosteum, affect the fracture end blood supply, extend recovery time; Simultaneously, the conventional pressurized screw has lighter resistance for shearing force, under the effect of shearing force, easily occurs loosening; Although lock screw has stronger resistance for shearing force, can not pressurize to the knochenbruch face, knochenbruch is in released state, is unfavorable for the knochenbruch healing; The profile of femur lockplate is not suitable for Minimally Invasive Surgery.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of femur lockplate, especially is suitable for fixing knochenbruch in bone surgery.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of femur lockplate, described femur lockplate two ends are class triangle termination, described femur lockplate two ends are provided with locating hole, described femur lockplate is axially arranged with lock hole and locking compress combination bore and described lock hole and described locking compress combination bore left-right symmetric along it arranges, and described femur lockplate one side is provided with relief groove.
Preferably, described lock hole has two at least, and described locking compress combination bore has two at least.
Preferably, described locking compress combination bore comprises arcuation counterbore and conical screw hole.
Preferably, described arcuation counterbore is provided with and adds pressure slope.
Preferably, the pressure slope gradient that adds of described arcuation counterbore is 30 °～50 °.
Preferably, the angle of thread of described conical screw hole is 15 °～25 °.
Preferably, the tapered screw thread of described conical screw hole is double thread.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, the femur lockplate can not only be resisted stronger shearing force and can pressurize to knochenbruch, and more firmly fixation of bone fragments, accelerate the healing of knochenbruch; Configuration design is more suitable for Minimally Invasive Surgery, reduces patient's surgical wound surface; Alleviate the pressure of femur lockplate to periosteum, reduce the impact on the knochenbruch blood supply, accelerate the knochenbruch healing.

The specific embodiment
As Figure 1-4, this utility model main body two ends are class triangle termination 5, and this design can be used for Minimally Invasive Surgery; Two ends are provided with locating hole 4, and are can be for Kirschner wire temporary fixed or sew up soft tissue; Along it, being axially arranged with lock hole 1 and locking compress combination bore 2 and lock hole 1 and locking compress combination bore 2 left-right symmetric arranges; Main body one side is provided with relief groove 3, alleviates the pressure of femur lockplate to periosteum, reduces the impact on the knochenbruch blood supply, accelerates the knochenbruch healing; Lock hole 1 has two at least, and locking compress combination bore 2 has two at least; Locking compress combination bore 2 comprises arcuation counterbore 7 and conical screw hole 8, and this hole can be according to practical situation choice for use forcing screw or lock screw; Arcuation counterbore 7 is provided with and adds pressure slope 6; Adding pressure slope 6 gradients is 40 °, and this adds pressure slope 6 can improve the pressurization effect; The angle of thread of conical screw hole 8 is 20 °; Tapered screw thread is double thread, increases locking intensity.
The work process of this example: while carrying out bone surgery, the femur lockplate is fitted in to the fracture that resets, select forcing screw and lock screw to position knochenbruch according to practical situation.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to this utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
