Abstract
The utility model relates to a two cores meet bone screw, have the pin fin and with the nail pole of a pin fin body coupling, the nail pole comprises thick pole and thin pole, through the frustum transition, set up cortex murices line on the thick pole between thick pole and the thin pole, seted up the spongy bone screw thread on the thin pole, interior hexagonal hole has been seted up on the pin fin top. The utility model discloses a what be close that the head uses is cortex murices line, carries on effectual fixedly in cortex osseous part position. Spongy bone screw thread for the tail end, it is effectively fixed at the spongy bone position. The head top is the design of interior hexagonal, can better faster wrong income operation position.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of twin-core bone screw.
Background technology
Present bone screw is divided into os integumentale screw and cancellous bone screw, and at treatment metaphysis position, fracture cannot be combined fixing by spongy bone with cortical bone, and Post operation screw needs retain a very long time in human body that bone just can be made to grow.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art existence, and providing a kind of can combine fixing twin-core bone screw effectively at fracture site.
The technical scheme realizing this utility model object is: a kind of twin-core bone screw, the nail bar having ailhead and be connected with ailhead one; Described nail bar is made up of thick bar and thin bar; By frustum transition between described thick bar and thin bar, thick bar offers cortical bone screw thread, thin bar offers cancellous threads; Described ailhead top offers inner hexagonal hole.
Described in technique scheme, ailhead is spherical in shape; Described thin bar afterbody is conical.
After adopting technique scheme, this utility model has following positive effect:
(1) of the present utility model is cortical bone screw thread close to head, effectively fixes at cortical bone site.Tail end cancellous threads, effectively fixing at cancellous bone site.Apical head is the design of interior hexagonal, can be screwed into operative site better faster.
(2) nail head spherical designs of the present utility model, can play pressurization after being screwed into blade plate, is healed faster in fracture line position.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Attached number in the figure is: ailhead 1, nail bar 2, thick bar 3, thin bar 4, frustum 5, cortical bone screw thread 6, cancellous threads 7, inner hexagonal hole 8.
Detailed description of the invention
(embodiment 1)
See Fig. 1 and Fig. 2, the nail bar 2 that this utility model has ailhead 1 and is connected with ailhead 1 one; Nail bar 2 is made up of thick bar 3 and thin bar 4; By frustum 5 transition between thick bar 3 and thin bar 4, thick bar 3 offers cortical bone screw thread 6, thin bar 4 offers cancellous threads 7; Ailhead 1 top offers inner hexagonal hole 8.Ailhead 1 is spherical in shape; Thin bar 4 afterbody is conical.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
