Abstract
The invention discloses the fixing steel plate of a kind of fracture of the tibial plateau, especially a kind of knee joint plateau steel plate.This steel plate entirety, in Z-shaped, is made up of steel plate head, plate body and steel plate tail, and steel plate head becomes the anglec of rotation to be the Rotational Symmetry of 180 degree with steel plate tail, steel plate head and steel plate tail are respectively equipped with several through holes; The thickness of plate body is greater than the thickness of steel plate head and steel plate tail; The thickness of steel plate head and steel plate tail is 1.2 ± 0.3mm, and the thickness of plate body is 6.0 ± 0.3mm; The both sides of plate body are provided with groove; Described number of openings is three; The edge of steel plate head and steel plate tail is circular arc.The present invention has that operative approach is simple, operation wound is little, can prevent subside displacement and lateral displacement, and need not be moulding, the advantage that fixed effect is desirable.
Description
Technical field
The present invention relates to the fixing steel plate of a kind of fracture of the tibial plateau, especially a kind of knee joint plateau steel plate.
Background technology
At present when processing nearly knee joint plateau place fracture, usually adopt T-steel plate, L-type steel plate or A0 steel plate, the thickness of these steel plates is mostly thicker, is difficult to realize Minimally Invasive Surgery, and easily cause operation wound large, wound not easily recovers.During use, the longitudinal holding power of T-steel plate or L-type steel plate is limited, be difficult to control longitudinal collapse displacement, and holding strength is limited, and the phenomenon of disconnected plate easily occurs; A0 steel plate is then difficult to moulding, and support strength is also more general.Traditional fracture processing method, also needs to pre-bend and cutting to steel plate in operation, and complicated operation can not complete docile skeletogenous shape.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of operative approach is simple, operation wound is little, can prevent subside displacement and lateral displacement, and need not be moulding, the knee joint plateau steel plate that fixed effect is desirable.
The present invention's adopted technical scheme that solves the problem is: this steel plate entirety is in Z-shaped, be made up of steel plate head, plate body and steel plate tail, steel plate head becomes the anglec of rotation to be the Rotational Symmetry of 180 degree with steel plate tail, steel plate head and steel plate tail are respectively equipped with several through holes; The thickness of plate body is greater than the thickness of steel plate head and steel plate tail.
The thickness of steel plate head of the present invention and steel plate tail is 1.2 ± 0.3mm, and the thickness of plate body is 6.0 ± 0.3mm.
The both sides of plate body of the present invention are provided with groove.
Number of openings of the present invention is three.
The edge of steel plate head of the present invention and steel plate tail is circular arc.
The thickness of steel plate head of the present invention and steel plate tail is 1.2mm, and the thickness of plate body (2) is 6.0mm.
The present invention compared with prior art, there is following beneficial effect: the head of this steel plate becomes the anglec of rotation to be the Rotational Symmetry of 180 degree with afterbody, steel plate head and afterbody adopt very thin slab construction, plate body then thickeies, gain in strength, and the groove being conducive to fracture location is provided with in plate body both sides, this steel plate does not need moulding when using, the situation significantly adjusting hone lamella profile in operation can be greatly reduced, reduce operating time, reduce operation risk, be conducive to patient and just carry out joint exercise in early days after surgery, the song recovering joint stretches function, reduce the generation of the complication such as traumatic arthritis.

Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the front view of the embodiment of the present invention.
Fig. 2 is the right view of the embodiment of the present invention.
Fig. 3 is the top view of the embodiment of the present invention.
Fig. 4 is the axonometric chart of the embodiment of the present invention.
Detailed description of the invention
See Fig. 1-Fig. 4, the present embodiment entirety is in Z-shaped, and be made up of steel plate head 1, plate body 2 and steel plate tail 3, steel plate head 1 and the steel plate tail 3 one-tenth anglec of rotation are the Rotational Symmetry of 180 degree, and namely steel plate head 1 is revolved turnback around central point and overlapped with steel plate tail 3.Steel plate head 1 and steel plate tail 3 are 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 tail 3, and the thickness of steel plate head 1 and steel plate tail 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 tail 3 is circular arc.
The material of steel plate head 1, plate body 2 and steel plate tail 3 is titanium alloy or stainless steel material.
During use, steel plate and skeleton face are fitted, then at through hole 4 place bone screw by Interal fixation at fracture.
