Abstract
The invention discloses a steel plate for fixing a tibial proximal fracture, and particularly relates to a knee joint fusion steel plate. The steel plate is composed of a steel plate head, a plate body and a steel plate tail, wherein the steel plate head, the plate body and the steel plate tail are connected into a whole. The included angle formed between the steel plate head and the plate body is 97-103 degrees. The included angle between the steel plate tail and the plate body is 147-153 degrees. A plurality of protruding steps are arranged on the steel plate head, the plate body and the steel plate tail. Screw holes are formed in the steps. The thickness of the steel plate head, the thickness of the plate body and the thickness of the steel plate tail are respectively 0.9-1.5mm. The edge of the steel plate head and the edge of the steel plate tail are respectively in a circular arc shape. The number of the steps and the number of the screw holes are respectively four. The knee joint fusion steel plate has the advantages that an operative route is simple, the fixing effect is ideal, an operative wound is small, and fracture reduction is easy.
Description
Technical field
The present invention relates to a kind of Proximal tibia fracture fixation steel plate, especially a kind of knee joint fusion steel plate.
Background technology
At present when fracture at nearly knee joint is processed, T-steel plate or L-type steel plate, mostly plate morphology knot are generally used
Structure, and steel plate is mostly all long.When using, the head of T-steel plate or L-type steel plate is close to joint outside, medical people
Member carries out bending so that steel plate can be integrally close at bone according to the bone profile of patient to steel plate, then several connecing of arranging in pairs or groups
Bone screws, by the Interal fixation in affected part.This traditional fracture processing method has many limitation, is first in operation
Need to carry out bending to steel plate, increased operating time, increase operation risk；Next to that the steel plate after bending is easily formed and answered
Power is concentrated, and causes Plate break；Steel plate also after bending can cause to fix bore deformation, cause bone screw to be fixed insecure,
So that the loosening and slippage of postoperative easy generation steel plate；Additionally due to steel plate is general all more long, operation wound is easily caused greatly, no
Easily recover.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of operative approach is simple, fixed effect is preferable, operation wound
The easy knee joint fusion steel plate of the small, reduction of the fracture.
The present invention the used technical scheme that solves the above problems is：The steel plate is by the steel plate head, the plate body that are connected
It is in 97-103 ° of angle between steel plate head and plate body with steel plate tail composition, in 147-153 ° of folder between steel plate tail and plate body
Angle；Steel plate head, plate body and steel plate tail are provided with the step of some projections, and screw hole is equipped with step.
The thickness of steel plate head of the present invention, plate body and steel plate tail is 0.9-1.5mm.
The edge of steel plate head of the present invention and steel plate tail is in circular arc.
The quantity of step of the present invention and screw hole is four.
It is in 100 ° of angles between steel plate head of the present invention and plate body.
It is in 150 ° of angles between steel plate tail of the present invention and plate body.
The thickness of steel plate head of the present invention, plate body and steel plate tail is 1.2mm.
The present invention compared with prior art, has the advantages that：1st, the steel plate when in use only need to slightly bend into
Row is moulding, greatly reduces the situation that steel plate profile is significantly adjusted in performing the operation, and reduces operating time, reduces operation risk；
2nd, the deformation produced because pulling folding can be reduced, it is to avoid the situation that postoperative generation steel plate is released or rocked, bone screw fixation；
3rd, the steel plate compact, thickness is only 0.9-1.5mm, such as opens up screw hole directly above, and bone screw cannot when using
It is fixed, four steps serve the local effect for thickening steel plate, and screw hole is opened up at step can increase thread turns, make
Bone screw is well fixed, while realizing the small Minimally Invasive Surgery effect of wound.

Specific embodiment
Referring to Fig. 1-Fig. 4, the present embodiment is made up of steel plate head 1, plate body 2 and the steel plate tail 3 being connected, steel plate
It is in 100 ° of angles between head 1 and plate body 2, is in 150 ° of angles between steel plate tail 3 and plate body 2.Steel plate head 1, plate body 2 and steel
Plate afterbody 3 is provided with four steps of projection 4, and four steps 4 are respectively positioned at the end of steel plate head 1, steel plate head 1 and plate body
Junction, the end of steel plate tail 2 of 2 junction, steel plate tail 3 and plate body 2, screw hole 5 is equipped with step 4.Steel plate
The thickness of head 1, plate body 2 and steel plate tail 3 is 1.2mm, and its material is titanium alloy or stainless steel material.Steel plate head 1 and steel
The edge of plate afterbody 3 is in circular arc.
When using, slightly bent according to human skeleton face, it is substantially fitted closely with bone face, then use synthetism spiral shell
Nail is by Interal fixation in fracture.
