Abstract
The utility model relates to the field of medical instrument technology, especially a kind of cannulated bone screws that can inject bone cement are made of head, bar portion and self tapping slot, hollow hole is equipped among screw, head is equipped with interior hexagonal turn slot, is external screw thread below bar portion, and external screw thread is equipped with thread groove.This design structure is simple, and cooperation bone cement also enhances the intensity of human limb bone using the intensity for not only enhancing nail itself.
Description
Technical field
The utility model relates to the field of medical instrument technology, especially a kind of cannulated bone screws that can inject bone cement.
Background technique
The cannulated bone screws sold currently on the market only have the function of individually fixed sclerite, and such fixation takes completely
Certainly in the intensity of cannulated bone screws, therefore the intensity of cannulated bone screws does not reach requirement the failure for being likely to result in operation.
Utility model content
In order to overcome the shortcomings of existing cannulated bone screws intensity, the utility model, which provides one kind, can inject bone cement
Cannulated bone screws.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of cannulated bone that can inject bone cement
Screw is made of head, bar portion and self tapping slot, and hollow hole is equipped among screw, and head is equipped with interior hexagonal turn slot, bar portion lower section
For external screw thread, external screw thread is equipped with thread groove, improves the fixed stability of cannulated bone screws.
Another embodiment according to the present utility model further comprises that thread groove is equipped with bone cement hole, bone cement hole
It is connected with hollow hole, realizes the possibility for injecting bone cement in screw, improve the intensity of cannulated bone screws, increase simultaneously
The intensity of strong skeleton.
The utility model has the beneficial effects that this design structure is simple, cooperation bone cement uses not only enhancing nail itself
Intensity, also enhance human limb bone intensity.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
1, head in figure, 2, bar portion, 3, self tapping slot, 4, interior hexagonal turn slot, 5, hollow hole, 6, external screw thread, 7, helicla flute,
8, bone cement hole.
Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of cannulated bone screws for injecting bone cement, by head 1,
Bar portion 2 and self tapping slot 3 form, and hollow hole 5 is equipped among screw, and it is outer spiral shell below bar portion 2 that head 1, which is equipped with interior hexagonal turn slot 4,
Line 6, external screw thread 6 are equipped with thread groove 7, improve the fixed stability of cannulated bone screws.Thread groove 7 is equipped with bone cement hole
8, bone cement hole 8 is connected with hollow hole 5, realizes the possibility for injecting bone cement in screw, improves cannulated bone screws
Intensity, while enhancing the intensity of skeleton.
In use, first with bone drill the good screw way of adjacent sclerite preboring, then in the insertion of turn bottle opener six
Angle turn slot 4 is screwed in along screw way, is compressed until adjacent sclerite, finally uses Cement fixation device bone cement in
Emptying aperture 5 injects, until bone cement fills up helicla flute 7.
