Abstract
The utility model belongs to the field of medical equipment, and particularly relates to an improved orthopedic screw. The improved orthopedic screw comprises a threaded rod and a hexagonal nut and is characterized in that a triangular groove is formed in the hexagonal nut, and the cross section of the hexagonal nut is a regular hexagon; the cross section of the triangular groove is a regular triangle, and the hexagonal nut and the center of the triangular groove coincide; and the depth of the triangular groove reaches the first lap of thread of the threaded rod from the top face. The improved orthopedic screw has a simple structure and is convenient to operate. As the improved orthopedic screw adopts the hexagonal nut and the triangular groove, a triangular screwdriver can be used, and a wrench can also be used. An appropriate tool can be selected as required, the improved orthopedic screw is conveniently taken out, a skid phenomenon can not occur, the screw-taking time is saved, the smooth performing of operations is ensured, and the pain of a patient is reduced.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of improved orthopaedics screw.
Background technology
Clinically, the doctor uses screw fixedly fracture site or fixation steel plate often to fracture patient operation, and after above even time several years, screw and osseous tissue are combined closely through half a year, and is very difficult when causing after the union of fracture taking-up screw.In addition, the groove of screw afterbody skids when getting nail easily through operation back broadening because wearing and tearing shoal for the first time, has prolonged and has got the nail time, has increased doctor's work difficulty, has also increased patient's misery.
Summary of the invention
For overcoming the shortcoming of prior art, the purpose of this utility model is to provide a kind of improved orthopaedics screw simple in structure, easy to operate, that take out easily when getting nail.
This utility model is that the technical scheme that its technical problem of solution adopts is: a kind of improved orthopaedics screw, comprise threaded rod, hex screw medicated cap, it is characterized in that, on the described hex screw medicated cap triangle groove is arranged, described hex screw medicated cap cross section is regular hexagon, the cross section of described triangle groove is equilateral triangle, and described hex screw medicated cap overlaps with the center of triangle groove, and the through threaded rod of the degree of depth of described triangle groove is from top several first lap screw threads.
The utlity model has following beneficial effect: this utility model is simple in structure, easy to operate, because this utility model adopts hex screw medicated cap and triangle groove, both can use the triangle screwdriver, also can use spanner, can select suitable tools as required, the convenient taking-up skidding can not occur, saves and gets the nail time, guarantee to perform the operation and carry out smoothly, alleviate the patient suffering.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is vertical view of the present utility model.
Among the figure, 1, threaded rod, 2, the hex screw medicated cap, 3, the triangle groove.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is elaborated
A kind of improved orthopaedics screw, comprise threaded rod 1, hex screw medicated cap 2, on the described hex screw medicated cap 2 triangle groove 3 is arranged, described hex screw medicated cap 2 cross sections are regular hexagon, the cross section of described triangle groove 3 is equilateral triangle, described hex screw medicated cap 2 overlaps with the center of triangle groove 3, and the through threaded rod 1 of the degree of depth of described triangle groove 3 is from top several first lap screw threads.
In the operation, can use triangle screwdriver or spanner to get nail, avoid taking place skidding, convenient and swift, alleviate the patient suffering.
