Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of cross driver fixing for Universal screw nail in spinal column.
Background technology
Universal screw nail is the conventional internal fixation device of spinal column section, because its nail tail can adjust to all directions, thus solves uni-axial screws in the past and can not adapt to the shortcoming of connecting rod.Therefore, Universal screw nail is widely used in internal fixation of spine.But because before non-locking, its nail tail is movable, when carrying out with traditional anistree bottle opener putting nail or moving back nail, its nail tail is usually to all directions activity, therefore perturbation operation; Further, when assistant transmits screw to patient, screw often comes off from bottle opener, affects in art and operates.
Utility model content
For solving the technical problem of existing existence, this utility model embodiment provides a kind of cross driver fixing for Universal screw nail in spinal column, can avoid putting nail, move back in nail operating process follow closely tail activity to such an extent as to perturbation operation and screw easily from the generation that bottle opener comes off.
For achieving the above object, the technical scheme of this utility model embodiment is achieved in that
This utility model embodiment provides a kind of cross driver fixing for Universal screw nail in spinal column, this cross driver comprises: screwdriver rod, handle, described screwdriver rod is connected with handle, the end of described screwdriver rod is octagonal projection, described octagonal projection lateral symmetry is provided with a pair pin, on described screwdriver rod, cover is provided with fixed muffle, and the end of described fixed muffle is provided with screw thread.
In such scheme, the afterbody of described fixed muffle is provided with the turnbarrel that diameter is greater than fixed muffle.
In such scheme, the end of described screwdriver rod and Universal screw nail follow closely the recessed fit of tail, and a pair pin of described screwdriver rod is arranged in the breach of Universal screw nail nail tail, and the end of described Universal screw nail nail tail is connected with fixed muffle by the screw thread of fixed muffle end.
In such scheme, described screwdriver rod and handle are rapid plug structure.
Compared with prior art, the beneficial effects of the utility model:
This utility model is rational in infrastructure, can avoid putting nail, move back in nail operating process and follow closely tail movable to such an extent as to perturbation operation and screw easily from the generation that bottle opener comes off, and is easy to tightening of Universal screw nail in performing the operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
This utility model embodiment provides a kind of cross driver fixing for Universal screw nail in spinal column, as shown in Figure 1, this cross driver comprises: screwdriver rod 1, handle 2, described screwdriver rod 1 is connected with handle 2, the end of described screwdriver rod 1 is octagonal projection, described octagonal projection lateral symmetry is provided with a pair pin 5, described a pair pin 5 forms a cross with screwdriver rod 1, described a pair pin 5 can be stuck in Universal screw nail 6 and follow closely in the breach of tail, play the effect of staple tail, thus avoid the movable interference to operation technique of nail tail in operation, on described screwdriver rod 1, cover is provided with fixed muffle 3, the end of described fixed muffle 3 is provided with screw thread.
The afterbody of described fixed muffle 3 is provided with the turnbarrel 4 that diameter is greater than fixed muffle 3, can increase by turnbarrel 4 screw thread that the arm of force is beneficial to manual rotation fixed muffle 3 end, and fixed muffle 3 is connected and fixed with the nail tail of Universal screw nail 6.
As shown in Figure 2, the end of described screwdriver rod 1 and Universal screw nail 6 follow closely the recessed fit of tail, a pair pin 5 of described screwdriver rod 1 is arranged on Universal screw nail 6 and follows closely in the breach of tail, and the end that described Universal screw nail 6 follows closely tail is connected with fixed muffle 3 by the screw thread of fixed muffle 3 end.
Described screwdriver rod 1 is rapid plug structure with handle 2, is convenient to change screwdriver rod 1, uses other instruments.
Work process of the present utility model: as shown in Figure 2, the octagonal projection of described screwdriver rod 1 end extend into Universal screw nail 6 and follows closely in the depression of tail, then a pair pin 5 is stuck in the breach that Universal screw nail 6 follows closely tail, finally rotating fixed muffle 3 makes the screw advancement of end in nail tail, like this, Universal screw nail 6 and cross driver form an entirety, cross driver would not come off, be beneficial to the transmission of apparatus, also make Universal screw nail 6 become uni-axial screws putting nail or move back in nail process simultaneously, operate so more convenient; After being inserted completely by Universal screw nail 6, rotate the screw thread that fixed muffle 3 exits its end, pull up cross driver, nail tail has just recovered mobility, thus can adapt to connecting rod by adjustment direction.
The above; be only preferred embodiment of the present utility model; be not intended to limit protection domain of the present utility model, all do in 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.
