Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The bone fracture plate for wrist joint fracture shown in fig. 1 and 2 is the best embodiment of the present invention, and comprises a fixing plate, wherein the fixing plate comprises a palm finger supporting plate 7, a palm wrist connecting plate 6 and a radius supporting plate 4, and the palm finger supporting plate 7, the palm wrist connecting plate 6 and the radius supporting plate 4 are of an integrally formed structure. The palm and finger supporting plate 7 and the radius supporting plate 4 are both of a flat structure, and the palm and wrist connecting plate 6 is adapted to the connection between the palm and the wrist and the shape of the palm center is of an upward convex cambered surface structure.
4 front ends of radius layer board be connected with palm wrist connecting plate 6, the rear end has spout 8, spout 8 sliding connection have regulating plate 2, regulating plate 2 also be flat structure, and the articulated spacing support 3 that has of regulating plate 2 rear end, 4 lower surface intervals of radius layer board have and supply spacing support 3 to rotate the draw-in groove 5 that the card was gone into. The U-shaped limiting support 3 is of a U-shaped structure, and two ends of the U-shaped interface in the opening direction are respectively hinged with the rear end of the adjusting plate 2 through the torsion spring 1. The torsion of the torsion spring 1 presses the limiting bracket 3 in the clamping groove 5, so that the limiting bracket 3 is locked with the clamping groove 5. In the adjustment process, overcome the elasticity of torsional spring 1, pull spacing support 3 and make spacing support 3 break away from with draw-in groove 5, then can push and pull regulating plate 2 as required, adjust the overall length of regulating plate 2 and radius layer board 4 to suitable position, later with spacing support 3 rotate with draw-in groove 5 cooperation, under the effect of torsional spring 1, spacing support 3 and draw-in groove 5 locking, the length adjustment of accomplishing the coaptation board is fixed.
Meanwhile, in order to effectively improve the overall strength of the bone fracture plate and prevent the adjusting plate 2 from falling off the radius supporting plate 4 from the upper side, the sliding groove 8 in the surface of the radius supporting plate 4 is an embedded groove arranged in the radius supporting plate 4, and the adjusting plate 2 is embedded in the sliding groove 8 and slides in the sliding groove 8 in a pushing and pulling manner. The clamping grooves 5 are arranged at the position, close to the front end, of the lower surface of the radius supporting plate 4 at intervals, and the length, from the front end of the radius supporting plate 4, of the clamping groove 5 at the position farthest from the front end does not exceed 1/3 of the total length of the radius supporting plate 4, namely the maximum adjustable distance of the adjusting plate 2 does not exceed 1/3 of the total length of the radius supporting plate 4. The length of the adjusting plate 2 is consistent with that of the radius supporting plate 4, the setting of the maximum adjustable length limits the adjustable range of the adjusting plate 2, and at least 2/3 of the position of the adjusting plate 2 can be matched with the sliding groove 8 in the adjusting process, namely, the adjusting plate is embedded into the radius supporting plate 4, so that the adjusting plate is prevented from excessively falling out of the radius supporting plate 4 to generate angle deflection with the radius supporting plate 4, and the influence on normal fixation is avoided.
