Abstract
The utility model discloses an outer hexagonal bone screw which comprises a screw body, and is characterized in that an inner hexagon and an outer hexagon are arranged on a screw cap of the screw body, and the height of the outer hexagon is one to three millimeters. When the bone screw is used, once the inner hexagon of the screw slips off, another tool can be used and the screw can be taken out by making use of the outer hexagon. The outer hexagonal bone screw has the beneficial effects that the outer hexagonal bone screw is simple in structure; the success rate of taking the screw out is increased; pain of the patient, caused by the phenomena that the screw slips off, is reduced; and the work load of the medical staff is reduced.
Description
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of outer-hexagonal bone screw.
Background technology
At present, known orthopaedics is used for fixing the screw of steel plate, and its head of a nail all is a hexagon in the cylindrical; In clinical practice, find, this in hexagonal screw, be very easy to stripped thread; Particularly particularly serious in the taking-up process; Both prolong operating time, increased patient's misery, increased medical personnel's workload again.
Summary of the invention
This utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art, and a kind of simple structure is provided, outer-hexagonal bone screw easy to use.
This utility model solves the technical scheme that its technical problem adopted: a kind of outer-hexagonal bone screw, and it comprises the nail body, it is characterized in that; Hexagonal and outer-hexagonal in the head of a nail on the said nail body is provided with, outer-hexagonal is high 1～3 millimeter.During use,, just can use other instrument instead, utilize outer-hexagonal that screw is taken out at once in case the stripped thread phenomenon appears in hexagonal in the screw.
The beneficial effect of this utility model is: simple in structure, increased the success rate in the taking-up process, and reduced because of the misery that the stripped thread phenomenon causes to the patient occurring, alleviated medical personnel's workload again.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is the structural representation of this utility model embodiment.
Among the figure, 1. nail body, the 2. head of a nail, 3. in hexagonal, 4. outer-hexagonal.
The specific embodiment
In the drawings, a kind of outer-hexagonal bone screw, it comprises nail body 1, it is characterized in that; Hexagonal 3 and outer-hexagonal 4 in the head of a nail 2 on the said nail body 1 is provided with, outer-hexagonal 4 is high 1～3 millimeter.During use,, just can use other instrument instead, utilize outer-hexagonal 4 that screw is taken out at once in case the stripped thread phenomenon appears in hexagonal 3 in the screw.
