Abstract
The utility model relates to a steel plate for internal fixation used in orthopaedics. The utility model includes a steel plate and a bolt. The steel plate is provided with a terraced chute. Back of the steel plate is provided with a plurality of supporting points. The utility model has the advantages that the period of treatment is short, the curative effect is good, and the structure is simple, the operation is convenient, as well as the fixation is tight.
Description
This utility model relates to the orthopaedics internal fixation steel plate.
The limited contact dynamic compression plate of a kind of LC-DCP comprises steel plate and screw, is provided with ellipsoid shape chute on steel plate, and screw head is hemispherical, and the side between two chutes in the steel plate back side is provided with arc groove.During use, behind the screw-driving, can only once pressurize, can't realize persistent pressure, thereby prolong the fractures healing time, reduce sclerotin intensity; Secondly, steel plate and surface of bone contact area are bigger, are unfavorable for the growth of callus, also have the shortcoming of radially rotating.Chinese patent CN2404491Y discloses " a kind of orthopaedics internal fixation compression steel plate ", it comprises with the steel plate of a plurality of spherical elliptical apertures and lag screw, be a threaded connection hole at least respectively to be arranged at the two ends of steel plate, what match with threaded connection hole is supporting screw, the head periphery of supporting screw has the screw thread that is connected with steel plate, near screw head the cylinder step is being arranged, the forcing screw lower head that matches with elliptical aperture also has one section cylinder step, and the lag screw between compression steel plate and cortical bone layer and each forcing screw both sides have respectively and can be used for the pressurization cushion block that pressurizes and take out in fixing back.Shortcoming is to realize the persistent pressure effect, so the course of treatment is longer, curative effect is relatively poor.Chinese patent CN2201902Y disclosed " non-equal strength pressurize automatically fixing head ", described plate body (1) is to reduce gradually to the two ends area of section from a centre, and the bottom surface of plate body (1) becomes the arcual non-equicohesive cambered surface stripe board of concave surface at horizontal direction.Shortcoming is to have stress shielding between hold-down screw, causes the sclerotin intensity at this place less; Secondly steel plate is that face contacts with surface of bone, influences growth of spur; And structure is complicated, is awkward.
It is that face contacts with surface of bone that the purpose of this utility model is to solve prior art invar plate, thereby has influenced the regeneration of callus; And, cause the fractures healing rate slow, the problem that intensity is low because of screw and steel plate can not continue to slide the mutually stress shielding that causes and can't realize persistent pressure.
A kind of some contact persistent pressure internal fixation steel plate comprises steel plate and screw, and steel plate is provided with the step chute, and the steel plate back side is provided with several strong points.
Above-mentioned internal fixation steel plate, screw are shoulder screw, and the shoulder lower end of shoulder screw is concordant with strong point lower end.
Above-mentioned internal fixation steel plate, the shoulder chamfering of shoulder screw.
Above-mentioned internal fixation steel plate, the strong point are hemispherical, round table-like or cylindric.
Because of the steel plate of the present utility model back side is provided with the strong point, original steel plate contacted with the face of surface of bone change a contact into, enlarged space between steel plate and surface of bone, be beneficial to callus regeneration, on the other hand, reduced the friction area of steel plate and surface of bone, be beneficial to key fine motion, especially endwisely slip along steel plate, thereby be beneficial to persistent pressure and reduce stress shielding, improved the speed and the sclerotin intensity of fractures healing.If screw is a shoulder screw, reduced pressure between screw and steel, be beneficial to screw and in chute, slide, and then avoided stress shielding, realized persistent pressure simultaneously, further improved curative effect and shorten the course of treatment, made fractures reach a state near physiological healing.This utility model also has simple in structurely tightly to be played, is convenient to operate and the advantage of fixation.
Below in conjunction with accompanying drawing this utility model is described in detail.
Fig. 1 is the structural representation of present embodiment.
With reference to Fig. 1, present embodiment comprises steel plate 3 and shoulder screw 1, and steel plate is provided with step chute 2, the steel plate back side is provided with eight cylindric strong points 4, columnar stays point head is hemispherical, and the strong point is positioned near the chute sideline, and shoulder 5 lower ends of shoulder screw are concordant with strong point lower end.
The above-mentioned strong point can be hemispherical or round table-like, above-mentioned step chute and can be ellipsoid shape or taper.
Claims (4)
1, a kind of some contact persistent pressure internal fixation steel plate comprises steel plate and screw, it is characterized in that steel plate is provided with the step chute, and the steel plate back side is provided with several strong points.
2, internal fixation steel plate as claimed in claim 1 it is characterized in that screw is a shoulder screw, and the shoulder lower end of shoulder screw is concordant with strong point lower end.
3, internal fixation steel plate as claimed in claim 2 is characterized in that the shoulder chamfering of shoulder screw.
4,, it is characterized in that the strong point is hemispherical, round table-like or cylindric as the described internal fixation steel plate of the arbitrary claim of claim 1-3.
