Abstract
The utility model relates to a medical instrument, in particular to a novel fracture outer fixing device. The technical scheme is that the novel fracture outer fixing device comprises an upper support plate, a wedge-shaped protrusion, a wedge-shaped groove and a lower support plate. The upper support plate and the lower support plate are in a semi-cylindrical shape, the wedge-shaped protrusion is arranged on the outer side of the upper support plate, the wedge-shaped groove is arranged in the inner side of the lower support plate, and the wedge-shaped groove and the wedge-shaped protrusion are matched. The novel fracture outer fixing device has the advantages that through matching of the wedge-shaped groove and the wedge-shaped protrusion, the fixing elasticity of fracture can be adjusted conveniently, and the pains of patients are released. In addition, the wedge-shaped groove and the wedge-shaped protrusion are respectively provided with a positioning groove and a positioning protrusion, and accordingly the sliding displacement of the upper support plate and the lower support plate can be effectively avoided.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of novel external fixation device for fracture.
Background technology
The outer treatment of bone generally is: the doctor sees and treat patients and generally fixedly hinders at first simply limb behind the patient, in case cause the nervus vasculairs damage when moving patient; Postoperative promotes as early as possible recovery and the growth of injury growing point in order to strengthen surgical effect, prevents that inside-fixture from becoming flexible, fractureing or rotation etc., mostly adopts Gypsum Fibrosum fixing outward.But it is as follows that it exposes some defectives: the one, and the operation of reinforcing Gypsum Fibrosum is wet work, very easily pollutes the dressing at the place that binds up a wound, compound fracture, can't fix by Gypsum Fibrosum before the art, and the out-of-flatness of gypsum sets rear surface causes suffering to patient, even Pressure Ulcers; The 2nd, according to patient's wound degree, opportunity of operation and fat or thin different situations, the degree of tightness in the time of fixedly is also thereupon different, and is difficult to grasp during planter cast, and tension causes thrombosis, pine then do not have outer fixation etc. problem.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of novel external fixation device for fracture is provided, and can adjust easily the fracture fixation degree of tightness, has alleviated patient's misery.
Its technical scheme is: comprise mounting plate, wedge shape projection, wedge-shaped impression and bottom plate, described mounting plate and bottom plate adopt half cylindrical structure, the outside of mounting plate is provided with the wedge shape projection, and the inboard of bottom plate is provided with wedge-shaped impression, and wedge-shaped impression matches with the wedge shape projection.
The outside of above-mentioned wedge shape projection is provided with a plurality of positioning convex, is provided with a plurality of detents that match with positioning convex in the wedge-shaped impression.
The beneficial effects of the utility model are: match with the wedge shape projection by wedge-shaped impression, can adjust easily the fracture fixation degree of tightness, alleviated patient's misery; In addition, be respectively equipped with detent and positioning convex at wedge-shaped impression and wedge shape projection, can effectively prevent up and down supporting plate sliding transfer.
Description of drawings
Accompanying drawing 1 is side structure sketch map of the present utility model;
Accompanying drawing 2 is front views of the present utility model;
Among the upper figure: mounting plate 1, wedge shape projection 2, wedge-shaped impression 3, bottom plate 4, detent 5, positioning convex 6.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
This utility model comprises mounting plate 1, wedge shape projection 2, wedge-shaped impression 3 and bottom plate 4, described mounting plate 1 and bottom plate 4 adopt half cylindrical structure, the outside of mounting plate 1 is provided with wedge shape projection 2, the inboard of bottom plate 4 is provided with wedge-shaped impression 3, wedge-shaped impression 3 matches with wedge shape projection 2, can conveniently adjust the up and down fixedly elasticity of supporting plate; The outside of wedge shape projection 2 is provided with a plurality of positioning convex 6, is provided with a plurality of detents 5 that match with positioning convex 6 in the wedge-shaped impression 3.
Match with wedge shape projection 2 by wedge-shaped impression 3, can adjust easily the fracture fixation degree of tightness, alleviated patient's misery; In addition, be respectively equipped with detent 5 and positioning convex 6 in wedge-shaped impression 3 and wedge shape projection 2, can effectively prevent up and down supporting plate sliding transfer.
