Abstract
The utility model discloses a medical spinal bone screw. The medical spinal bone screw comprises a screw rod and a screw cap, wherein the screw cap is arranged at the tail of the screw rod, and the screw rod is provided external threads; and the external threads of the screw rod are double start threads. The external threads of the screw rod of the medical spinal bone screw are double start threads, so that the structure can save half of nailing time, increase the operation efficiency, and cause less pain for patients.
Description
Technical field
This utility model relates to a kind of medical spinal screw.
Background technology
When carrying out spinal operation, need use nail-stick system, and spinal screw is used for steel plate is fixed on the vertebral body.The method of the treatment of this internal fixation was used a lot of years clinically.Be used for the spinal screw that spinal operation uses, the head of a nail of screw is thicker.For screw is screwed into desired area, must on this position, carry out operative incision earlier, tool using is screwed into spinal screw then.The last nail time of spinal screw has directly influenced operation efficient; The thick head of a nail of screw makes that the incisura of operative incision is bigger simultaneously, thereby brings misery to sufferer.
The utility model content
This utility model first technical problem to be solved provides a kind of few medical spinal screw of misery that the nail time is short, cause to sufferer of going up.
In order to solve the problems of the technologies described above, the technical scheme that this utility model provided is: a kind of medical spinal screw, comprise the nail bar and the head of a nail, and the head of a nail is arranged on the afterbody of nail bar, and the nail bar is provided with external screw thread; The external screw thread of said nail bar is a double thread.
The said head of a nail adopts with the junction of nail bar and seamlessly transits.
The said head of a nail is provided with the U type groove that laterally runs through, and the both sides of U type groove are provided with relative hole.
After having adopted technique scheme, the utlity model has following beneficial effect: the external screw thread of the nail bar of (1) this utility model is a double thread, and this structure can be saved the half the last nail time, improves operation efficient.
(2) head of a nail of this utility model adopts with the junction of nail bar and seamlessly transits, and this structure can effectively reduce incisura, makes screw more like a cork in the implantable bone, reduces operating time, alleviates the misery of sufferer.
Description of drawings
For the content that makes this utility model is expressly understood more easily,, this utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the structural representation of this utility model.
Label in the accompanying drawing is:
The specific embodiment
(embodiment 1)
See Fig. 1, present embodiment comprises the nail bar 1 and the head of a nail 2.
The head of a nail 2 is arranged on the afterbody of nail bar 1, and nail bar 1 is provided with external screw thread 11.The external screw thread 11 of nail bar 1 is a double thread.Double thread can be saved the half the last nail time, improved operation efficient.The said head of a nail 2 adopts with the junction of nail bar 1 and seamlessly transits, and this structure can effectively reduce incisura, makes screw more like a cork in the implantable bone, reduces operating time, alleviates the misery of sufferer.The head of a nail 2 is provided with the U type groove 21 that laterally runs through, and the both sides of U type groove 21 are provided with relative hole 22.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to this utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of this utility model; Be not limited to this utility model; All within the spirit and principle of this utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of this utility model.
