Description
Technical field
This utility model relates to field of medical technology, particularly relates to a kind of medical bone nail.
Background technology
At present, in operation, the screw being similar to and general industry uses or self threading pin etc. is all adopted to carry out the operations such as bone connection or fixation implant.Nail fixing operation of the prior art, needs to carry out in two steps, the first step: boring, namely gets out bottom outlet and locate for nail on bone; Second step: be screwed into nail.But due to reasons such as bony structure, boring is operated in the trouble operated very in some operations.So, use nail of the prior art to be fixed or attended operation not only operating time is long, and the bad grasp of operation skill, and fixing easily generation the after fixing loosens, the later stage that can affect bone like this recovers, and nail is fixed on after in bone, when nail and bone contact tight, when needing to take out, existing nail not easily takes out, and wastes time and energy.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of medical bone nail.
This utility model is achieved through the following technical solutions:
A kind of medical bone nail, comprise the nail body in helicitic texture, described nail body upper end is provided with the head of a nail, what described head of a nail inside was provided with certain depth is polygonal dismounting groove, be provided with the removal rod be mated in described dismounting groove, described removal rod upper end is provided with dismounting cap, and described nail body is provided with several through holes, and the diameter of through hole increases after first reducing gradually gradually from top to bottom, the both sides, lower end of described nail body are provided with broken sword.
As preferably, described dismounting groove is pentagon or hexagon.
As preferably, described removal rod is formed in one with dismounting cap.
As preferably, the shape of described through hole is circular.
Compared with prior art, the beneficial effects of the utility model are: this utility model structure is simple, reasonable in design, this utility model is by arranging dismounting groove, removal rod and dismounting cap, like this when inner nail needs to take out, insert in dismounting groove with removal rod, adopt larger screwdriver to turn dismounting cap, nail can be taken out easily like this, time saving and energy saving; By arranging multiple circular hole, like this after nail is fixing, such nail and bone contact more closely, more firmly; By arranging broken sword, can cut bone, hole by broken sword so when mounted, be convenient to like this install with fixing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. nail body; 2. the head of a nail; 3. dismantle groove; 4. removal rod; 5. dismantle cap; 6. through hole; 7. broken sword.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Refer to Fig. 1, a kind of medical bone nail, comprise the nail body 1 in helicitic texture, described nail body 1 upper end is provided with the head of a nail 2, and what the described head of a nail 2 inside was provided with certain depth is polygonal dismounting groove 3, and described dismounting groove 3 is in pentagon or hexagon, be convenient to like this dismantle nail, be provided with the removal rod 4 be mated in described dismounting groove 3, described removal rod 4 upper end is provided with dismounting cap 5, and described removal rod 4 is formed in one with dismounting cap 5.Like this when inner nail needs to take out, insert in dismounting groove 3 with removal rod 4, adopt larger screwdriver to turn dismounting cap 5, nail can be taken out easily like this, time saving and energy saving.
Described nail body 1 is provided with several through holes 6, and the shape of described through hole 6 is circular, and the diameter of through hole 6 increases after first reducing gradually gradually from top to bottom, like this after nail is fixing, such nail and bone contact more closely, more firmly.The both sides, lower end of described nail body 1 are provided with broken sword 7, can be cut, be holed by broken sword 7 pairs of bones so when mounted, are convenient to like this install with fixing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
