Abstract
The utility model relates to an automatic pressurizing cross-fixation bone-setting steel-plate, composed of a middle edge 1, side edges 2 and a bottom edge which form an arc-shaped cross-section. The middle edge 1 is provided with a pressurizing screw hole 4. Two side edges 2 are provided with crossing screw-fixing holes 5. The bottom edge of the bone-setting steel plate forms a riding and straddling shape and is fixedly contacted with the bone-trunk. The screws are arranged in a crossing form and are fastened to the bone-trunk, so that screw pulling can be prevented and intensity of bending resistance and stiffness of the steel plate and stability of both ends of the fractured bone can be enhanced. Accelerating fracture healing, shortening the treatment course, the utility model has the advantages of simple structure and convenient operation of the surgical operation, and is particularly suitable for thighbone fracture.
Description
This utility model belongs to medical apparatus and instruments, is a kind of internal fixation steel plate that is used for synthetism.
So far, hospital adopts square-section equal thickness steel plate and square-section not to wait two kinds of steel plates always, these two kinds of steel plates all are that the monoplane is fixed, fixed screw position all in one plane, the direction of its power is also consistent, so poor stability, easy nail pulling, rigidity is poor, easily bent plate, disconnected plate, postoperative are suffered from the limb braking time, and length, healing time prolong.
The purpose of this utility model is that a kind of nail pulling that prevents will be provided, bent plate and disconnected plate, the stability of raising fracture segment, the synthetism internal fixation steel plate of accelerating union of bone fracture.
Solution of the present utility model is a kind of arch of design cross section equal thickness steel plate, with middle edge, two arris and bipod limit constitute the arch cross section, and two arris are provided with the cross screws hole, middle edge is provided with the forcing screw hole, and two arris form the subtend angle that equates with middle edge.
Below in conjunction with accompanying drawing this utility model is specified:
Fig. 1 is this utility model sketch map;
Fig. 2 is this utility model cross section cut-away view that is fixed on the backbone.
This utility model is by middle edge 1, the arris 2 and the arm of angle 3 constitute, two arris 2 form the subtend angle that equates with middle edge 1, the edge of two arris 2 has foot limit 3 respectively, make this synthetism steel plate form the arch cross section, middle edge 1 is provided with forcing screw hole 4, two arris 2 and is provided with intersection fixing screw hole 5.Make like this by intersecting the screw of fixing screw hole 5 and be staggered form and be fixed on the backbone, the screw of intersection is in shearing condition mutually, antagonism nail pulling power, there is automatic slippage pressurization in two forcing screw holes 4 on the middle edge 1, screw wherein and middle edge 1 are fixed on the backbone in vertical direction, also with two arris 2 on screw be the staggered form fixed position, obviously increased the bed knife between steel plate and the backbone.Two foot limits 3 of steel plate directly are straddle-type with the surface of bone of Jinyuan Garden shape and contact fixing, make semiorbicular hold of steel plate and key generation, increased the stability of steel plate and two fracture segments, because bipod limit 3 is the angle steel spline structure with plate body, obviously the improving of bending strength with rigidity.Middle edge 1, two arris 2 of steel plate does not contact with surface of bone, has reduced the osteanabrosis area that steel plate contacts with surface of bone, helps knitting, shortens the course of treatment.
This utility model is simple in structure, and is easy to operate during operation, is specially adapted to the thigh bone fracture.
