Abstract
The utility model provides a bone screw of screw in fast, relates to an orthopedic medical equipment. Including screw cap (1), threaded rod (2), its characterized in that, the screw thread on threaded rod (2) be double thread (5), the head of threaded rod (2) is equipped with more than the sword self tapping groove (3). The utility model discloses screw thread on the threaded rod is the double thread for operation shi doctor very reduces twisting or back -out time of bone screw, the head of threaded rod is equipped with self tapping groove more than the sword, can directly twist bone screw in fracture department, and the time of attacking fracture department screw thread when adopting current bone screw operation with surgical instruments has been removed from to this structure, simultaneously, the control power of bone screw on bone very strengthens, has reduced the internal fixation inefficacy that brings because of bone screw is not hard up.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, particularly a kind of bone screw that can screw in fast.
Background technology
At present, fracture repair operation is very general clinically, and bone screw becomes a part indispensable in fracture repair operation.But, in traditional operation, can be very loaded down with trivial details when screw twisted by bone screw, especially closely-pitched bone screw, because the pitch of screw is little, the number of turns is many, doctor needs the expensive time usually in the process being screwed into screw, and, when after union of fracture, need knockout screw equally, a lot of time can be expended equally.Because operating time lengthens, add the operating time of doctor, meanwhile, add the misery of patient.
Summary of the invention
The purpose of this utility model is that overcoming traditional bone screw is screwed into or screws out the large problem of time consumption, for clinical operation provides a kind of bone screw that can screw in fast, it can reduce doctor and be screwed into or screw out time spent by screw, decreases the misery of performing the operation and bringing patient.
Above-mentioned goal of the invention is achieved through the following technical solutions, and a kind of bone screw that can screw in fast, comprises screw cap, threaded rod, and its main points are, the described screw thread on threaded rod is double thread, and the head of threaded rod is provided with the above self tapping groove of a sword.
As preferably, the double thread on described threaded rod is cortical bone screw thread or cancellous threads or fine thread.
As preferably, described screw cap is provided with Flos Mume groove.
Compared with prior art, this utility model has following beneficial effect: the screw thread on threaded rod is double thread, and the operation time that Shi doctor had been screwed into or was screwing out bone screw is greatly reduced; The head of threaded rod is provided with the above self tapping groove of a sword, can directly be screwed into bone screw in fracture, and this structure eliminates the time of attacking fracture screw thread when adopting the operation of existing bone screw by operating theater instruments; Meanwhile, the hold of bone screw on bone greatly strengthens, and decreases the fixation failure because bone screws loosen brings.

Fig. 3 is A-A sectional view of Fig. 1
Fig. 4 is 3 dimensional drawing of the present utility model
In Fig. 1-4,1-screw cap, 2-threaded rod, 3-self tapping groove, 4-Flos Mume groove, 5-double thread.
Detailed description of the invention
Embodiment below just represented by Fig. 1-4 is further described this utility model: comprise screw cap 1, threaded rod 2, the described screw thread on threaded rod 2 is double thread 5, and the head of threaded rod 2 is provided with three sword self tapping grooves 3; Double thread 5 on described threaded rod 2 is cortical bone screw thread; Described screw cap 1 is provided with Flos Mume groove 4.
During operation, the Flos Mume groove 4 of bone screw is connected with operation spanner, bone is first used drill bit bottoming hole, then, double thread bone screw with self tapping groove 3 is screwed into bone along bottom outlet, due to the existence of double thread 5, be screwed into the number of turns and compare and decrease half with conventional threads, save the time being screwed into screw; Now, self tapping groove 3 plays the effect of tapping, and bone screw is screwed in process, good directionality, and rate of penetration is fast; The design of Flos Mume groove 4, prevents spanner and Flos Mume groove from occurring skidding, makes transmission more effective, stable.Above-described embodiment structure is simple, easy to use, and while guarantee surgical quality, saves operating time.
