In order to solve the problem, this utility model provides Medical anchoring nail, comprises bolt body and base, it is characterized in that, described bolt body is in the sharp sample of cone, and described base is cruciate flower shape or double check with a core shape, base edge arranges an aperture, at aperture arranged outside one draw-in groove.
As a preferred version, described base edge arranges a circle projection, and described draw-in groove is arranged in projection.
The utility model has the advantage of, (1) bolt base is cruciate flower shape or double check with a core shape, common medical Phillips screwdriver can be used anchor studs to be screwed into completely in bone, can not give prominence to outside bone.(2) base edge arranges aperture, and for penetrating anchor line, when being screwed into anchor studs, anchor line is placed in the draw-in groove outside aperture, does not affect operation technique.
Accompanying drawing explanation
Fig. 1 is this utility model front schematic view.
Fig. 2 is this utility model base cruciate flower structural representation.
Label in figure is: 1---bolt body; 2---base; 21---draw-in groove; 22---aperture; 23---cruciate flower shape; 24---projection.
Detailed description of the invention
Elaborate to this utility model below in conjunction with accompanying drawing, the purposes of embodiment is only to explain the present invention and non-limiting technical scheme.
Embodiment 1.
Refer to Fig. 1 and Fig. 2, Fig. 1 is this utility model front schematic view, and Fig. 2 is this utility model base cruciate flower structural representation, can see understructure clearly.
Medical anchoring nail comprises bolt body 1 and base 2, described bolt body 1 is in the sharp sample of cone, base 2 is in cruciate flower shape 23, base also can be double check with a core shape, base 2 edge arranges an aperture 22, at aperture 22 arranged outside one draw-in groove 21, base 2 edge arranges a circle projection 24, and described draw-in groove 21 is arranged in projection 24.
The projection of base edge can be a circle, also can be one section, and the object arranging projection is to arrange the draw-in groove placing anchor line.
It should be noted that, Medical anchoring nail adopts titanium material to make, and can ensure its hardness and corrosion resistance.Bolt base is cruciate flower shape or double check with a core shape, common medical Phillips screwdriver can be used anchor studs to be screwed into completely in bone, namely meniscus can be stably fixed at the top that remporomandibular joint condyle is prominent, and base can be screwed in bone completely, can not give prominence at bone outside.Base edge arranges aperture, for penetrating anchor line, first anchor line is put on before using, and without the need to penetrating anchor line again in operation process, saves operating time.When being screwed into anchor studs, anchor line is placed in the draw-in groove outside aperture, does not affect operation technique.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
