Abstract
The utility model relates to an adjustable radius board that resets belongs to the medical instrument field, is applicable to among the bone surgery. This adjustable radius board that resets includes radius wrench (1), radius plate body (2) and rotation axis (3), adjustable radius board that resets designs into split typely, it is rotatory that rotation axis (3) can be wound in radius wrench (1), the elder generation opens little incision at the position of fracturing during the operation, implant adjustable radius board that resets, with radius plate body (2) with the fix with screw to the radius, again with radius wrench (1) with fix with screw to the radius distal end that sinks or fracture, draw the screw to reset the damage position of radius distal end through carrying, in passing round hole (9) and U type groove (7) screw in bone with the screw at last fix a position the coaptation board.
Description
Technical field
This utility model relates to adjustable reset radius plates, belongs to medical instruments field, is applicable in bone surgery.
Background technology
Radius far-end fracture is a kind of multiple fracture, and the method for the treatment of radius far-end fracture at present still resets with traditional operation method, Gypsum Fibrosum extenal fixation is in the majority.The method can obtain comparatively satisfied curative effect to the abarticular Fracture Simple of most of distal radius, but to the comminuted fracture of distal radius of instability, especially intra-articular fracture, simple Gypsum Fibrosum extenal fixation is difficult to accomplish the good para-position of articular surface and firm fixing, and then cause the requirement of oar wrist and articulatio radioulnaris osteoarthritis, median nerve and Ulnar nerve compression, the rehabilitation of intractable wrist joint function, in recent years internal fixation operation treatment is come into effect to radioulnaris distalis comminuted fracture.Many directions according to distal radius displacement of the selection of radius far-end fracture operative incision in the past and determine, the displacement of distal radius thenad side adopts Volar approach, and distal radius is to dorsal displacement employing dorsal part otch.The fracture far-end of radius far-end fracture is common to dorsal displacement, and the fracture far-end docile of steel plate far-end and displacement therefore can be utilized in above-mentioned operation to fix, at sled laminated steel near-end to reach reduction of the fracture effect.This technology is very effective.We are referred to as " steel plate sled pressure resets "
But above-mentioned distal radial palmar tube sheet technology exists to be damaged the cut-out of pronator quadratus, and the pronator quadratus after damage is difficult to sew up.A kind of novel internal fixtion placement technique of recent appearance is exactly do not cut off the technology that pronator quadratus inserts steel plate, because the obstruct " steel plate sled pressure technology " of pronator quadratus is difficult to realize.
Therefore new steel plate is designed to solve this contradiction.
Summary of the invention
The purpose of this utility model is: for prior art Problems existing, provides adjustable reset radius plates, can realize minimal incision * and implant fixing head, not need to reset in advance before implanting adjustable reset radius plates.
To achieve these goals, this utility model provides adjustable reset radius plates, meet physiological anatomic architecture, described adjustable reset radius plates comprises radius wrench, radius plate body and rotating shaft, radius wrench there is the double thread hole of seven band taperings, lower end part has concave surface and through hole, and concave surface has U-type groove; Radius plate body left end head matches with the concave surface of radius wrench, head has circular hole and through hole, there is the double thread hole of band tapering at the position that raises up of radius plate body, and middle part is the oblong slots of band ball-and-socket, and there is the double thread hole of two band taperings radius plate body tail end position.

Detailed description of the invention
For making the purpose of this utility model, technical scheme clearly, below in conjunction with accompanying drawing, this utility model is described in further detail.
Shown in Fig. 5, this utility model provides adjustable reset radius plates, comprises radius wrench 1, radius plate body 2 and rotating shaft 3, radius wrench 1 has the double thread hole 4 of seven band taperings, and lower end part has concave surface 5 and through hole 6, concave surface 5 has U-type groove 7; Radius plate body 2 left end head 8 matches with the concave surface 5 of radius wrench 1, head has circular hole 9 and through hole 10, there is the double thread hole 12 of band tapering at the position 11 that raises up of radius plate body 2, middle part is the oblong slots 13 of band ball-and-socket, and there is the double thread hole 15 of two band taperings radius plate body tail end position 14.
The exterior contour of described radius wrench 1 meets physiological anatomic architecture, and double thread hole 4 increases the fixing stability of sclerite by angulation, and compared with the screwed hole be parallel to each other with traditional axis, angulation is fixing more firm.
Described adjustable reset radius plates is designed to split type, radius wrench 1 can rotate around rotating shaft 3, first minimal incision * is opened at fracture site during operation, implant adjustable reset radius plates, radius plate body 2 is screwed on radius, again radius wrench 1 is screwed the distal radius subsiding or fracture, by lift screw, the damage location of distal radius is resetted, finally screw is screwed in bone through circular hole 9 and U-type groove 7 and blade plate is located.
