Abstract
The utility model discloses a steel plate used for tibial plateau fracture fixation, and particularly relates to a knee joint plateau steel plate. The steel plate is integrally in a Z shape, and consists of a steel plate head part, a plate body and a steel plate tail part, wherein the steel plate head part and the steel plate tail part are in rotational symmetry with the rotation angle being 180 degrees, and are provided with a plurality of through holes respectively, the thickness of the plate body is greater than the thickness of the steel plate head part and the steel plate tail part, the thickness of the steel plate head part and the steel plate tail part is 1.2+/-0.3mm, the thickness of the plate body is 6.0+/-0.3mm, grooves are arranged at the two sides of the plate body, the number of the through holes is three, and the edge of the steel plate head part and the steel plate tail part is in an arc shape. The knee joint plateau steel plate has the advantages of simple operation approach, small operation wound, capability of preventing collapsed displacement and lateral displacement, no need of shaping and ideal fixation effect.
Description
Technical field
It is fixing with steel plate that this utility model relates to a kind of fracture of the tibial plateau, especially a kind of knee joint platform steel plate.
Background technology
In the time processing nearly knee joint platform place fracture, conventionally adopt T-steel plate, L-type steel plate or A0 steel plate at present, the thickness of these steel plates is mostly thicker, is difficult to realize Minimally Invasive Surgery, easily causes operation wound large, and wound is difficult for recovering.When use, the longitudinal holding power of T-steel plate or L-type steel plate is limited, is difficult to control longitudinal collapse displacement, and holding strength is limited, and the phenomenon of disconnected plate easily occurs; A0 steel plate is difficult to moulding, and support strength is also more general.Traditional fracture processing method also needs steel plate to pre-bend and cutting in operation, and complicated operation can not completely docile skeletogenous shape.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of operative approach is simple, operation wound is little, can prevent from subsiding displacement and lateral displacement, and need not be moulding, the knee joint platform steel plate that fixed effect is desirable.
The technical scheme in the invention for solving the above technical problem is: this steel plate entirety is Z-shaped, formed by steel plate head, plate body and steel plate afterbody, steel plate head becomes the anglec of rotation with steel plate afterbody be the Rotational Symmetry of 180 degree, on steel plate head and steel plate afterbody, is respectively equipped with several through holes; The thickness of plate body is greater than the thickness of steel plate head and steel plate afterbody.
The thickness of steel plate head described in the utility model and steel plate afterbody is 1.2 ± 0.3mm, and the thickness of plate body is 6.0 ± 0.3mm.
The both sides of plate body described in the utility model are provided with groove.
Number of openings described in the utility model is three.
The edge of steel plate head described in the utility model and steel plate afterbody is circular arc.
The thickness of steel plate head described in the utility model and steel plate afterbody is 1.2mm, and the thickness of plate body (2) is 6.0mm.
This utility model compared with prior art, there is following beneficial effect: the head of this steel plate becomes the anglec of rotation with afterbody be the Rotational Symmetry of 180 degree, steel plate head and afterbody adopt slab construction as thin as a wafer, plate body is thickeied, gain in strength, and be provided with the groove that is conducive to fracture location in plate body both sides, this steel plate does not need moulding while use, can greatly reduce the situation of significantly adjusting hone lamella profile in operation, reduce operating time, reduce operation risk, be conducive to patient and just carry out joint exercise at early postoperative period, recover the song in joint and stretch function, reduce the generation of the complication such as traumatic arthritis.

Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the front view of this utility model embodiment.
Fig. 2 is the right view of this utility model embodiment.
Fig. 3 is the top view of this utility model embodiment.
Fig. 4 is the axonometric chart of this utility model embodiment.
The specific embodiment
Referring to Fig. 1-Fig. 4, the present embodiment entirety is Z-shaped, is made up of steel plate head 1, plate body 2 and steel plate afterbody 3, and 3 one-tenth anglecs of rotation of steel plate head 1 and steel plate afterbody are the Rotational Symmetry of 180 degree, and steel plate head 1 overlaps with steel plate afterbody 3 around central point Rotate 180 degree.On steel plate head 1 and steel plate afterbody 3, be respectively equipped with three through holes 4.The thickness of plate body 2 is greater than the thickness of steel plate head 1 and steel plate afterbody 3, and the thickness of steel plate head 1 and steel plate afterbody 3 is 1.2mm, and the thickness of plate body 2 is 6.0mm.The both sides of plate body 2 are provided with groove 5.The edge of steel plate head 1 and steel plate afterbody 3 is circular arc.
The material of steel plate head 1, plate body 2 and steel plate afterbody 3 is titanium alloy or stainless steel material.
When use, by steel plate and the laminating of skeleton face, then with bone screw, steel plate is fixed on to fracture at through hole 4 places.
