Abstract
The utility model discloses a hollow screw locking plate, which comprises a plate body, wherein a plurality of threaded holes and a plurality of through holes are arranged on the plate body, the threaded holes penetrate through the front and back sides of the plate body, in addition, axial lines of the threaded holes are in non-parallel arrangement, the through holes penetrate through the front and back sides of the plate body, the diameter of each threaded hole is greater than the diameter of each through hole, and a hollow locking screw is respectively connected into each threaded hole. The hollow screw locking plate has the advantages that the locking plate adopts the plate and screw integration, the anti-rotation capability can be improved, the bone fracture end can be pressed, the screw cutting out from the caput femoris and the screw unscrewing after the operation can be prevented, and the firm internal fixation can be realized.
Description
Technical field
This utility model relates to a kind of hollow nail lockplate, particularly a kind of hollow nail lockplate that is used for the treatment of fracture of femoral neck.
Background technology
At present clinically, be used for the treatment of the hollow nail of fracture of femoral neck, it has following deficiency: treatment is during fracture of femoral neck, and the postoperative screw cuts out and after screw withdraws from, causes phenomenons such as neck of femur cripetura easily from femoral head, influences therapeutic effect.
The utility model content
This utility model provides a kind of hollow nail lockplate, and it has overcome the existing deficiency of hollow nail lockplate in the background technology.
The technical scheme that is adopted that this utility model solves its technical problem is:
A kind of hollow nail lockplate, it has a plate body, offer a plurality of screwed hole and a plurality of through holes that run through the positive back side of plate body that run through the positive back side of plate body and the non-parallel layout of axis on the described plate body, described screwed hole diameter all is connected with a hollow lock screw greater than through-hole diameter within described each screwed hole.
Among one preferred embodiment: described screwed hole number is four, and described four screw hole arrangement become Y shape.
Among one preferred embodiment: described through hole number is two, and described two through holes all are located between adjacent two screwed holes.
Among one preferred embodiment: a described through hole is located between two screwed holes of the opening part of Y shape layout.
Among one preferred embodiment: described another through hole is located between two screwed holes on the bifurcated limit of Y shape layout.
The technical program is compared with background technology, and it has following advantage:
1, it is integrated that lockplate adopts the plate nail, then can improve anti-rotational ability, can pressurize to fracture site, can prevent that the postoperative screw from cutting out and screw withdraws from from femoral head, can realize strong internal fixation;
2, the non-parallel layout of a plurality of screwed hole axis can realize that multi-angle fixes, and prevents collapse of the femoral head, can realize that many planes fix, and increases hold, effectively prevents to become flexible, move back nail;
3, four screw hole arrangement become Y shape, through hole be located between two screwed holes of the opening part of Y shape layout, another through hole is located between two screwed holes on the bifurcated limit of Y shape layout, can realize strong internal fixation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated the schematic perspective view of hollow nail lockplate.
The specific embodiment
Please refer to Fig. 1 to Fig. 3, a kind of hollow nail lockplate, it has a plate body 100, offers four screwed hole 110 and two through holes 120 that run through the plate body 100 positive back sides that run through the plate body 100 positive back sides and the non-parallel layout of axis on the described plate body.Described screwed hole 110 diameters are greater than through hole 120 diameters.The shape of described plate body 100 designs as required.
Described four screwed holes 110 are arranged to Y shape, and, all be connected with a hollow lock screw within described each screwed hole 110.
Described two through holes 120 all are located between adjacent two screwed holes 110.Among one preferred embodiment: a described through hole 120 is located between two screwed holes 110 of the opening part of Y shape layout; Described another through hole 120 is located between two screwed holes 110 on the bifurcated limit of Y shape layout.
Among the present embodiment, adopt the step of hollow nail lockplate clinical treatment followingly to describe:
1, user should read over " orthopaedics internal fixation " and other related datas that AO organizational technology is recommended before using this product.And the skillfully operating process of this product.
2, patient body position: generally taking dorsal position, is principle to make things convenient for operation technique, the patient is not had sense of discomfort.
3, operative incision: longitudinal cut, the otch size should be able to be put into implant, obtains surgical field of view clearly.
4, separate subcutaneous tissue and muscle, expose femoral trochanteric.
5, plate is positioned over the femoral trochanteric outside after fracture end is resetted, after electric drill boring, the depth measurement, selects the hollow lock screw of appropriate length, be screwed into the locking of nail road with torsion screwdriver.
The above, it only is this utility model preferred embodiment, so can not limit the scope that this utility model is implemented according to this, i.e. the equivalence of doing according to this utility model claim and description changes and modifies, and all should still belong in the scope that this utility model contains.
