Abstract
This utility model belongs to medical instruments field, a kind of self-taped type screw with ring gauges, be provided with the nail head (2) that the nail tip (1) of band self tapping groove and threaded length are fixed, be carved with nail bar (3) and the prismatoidal nail tail (4) of ring gauges, it is characterized in that nail tip (1) can along the tapping guide nail head (2) to be screwed in bone voluntarily of pre-bore bone hole, nail bar (3) scale is made up of three groups of camber lines that the length being uniformly distributed in nail bar (3) Zhou Jing is alternate, can reading numerical values from different perspectives, nail tail (4) is prismatic, conveniently firmly be connected with bone drill, self tapping is utilized to be screwed into fixing, ring gauges is measured, formed the direct Measurement accuracy of the degree of depth being screwed into bone inner bolt, it is simple that it has structure, easy to operate, measure the advantages such as accurate.
Description
Technical field
This utility model belongs to medical instruments field, relate in Orthopedic Clinical the exterior fixation bracket self-taped type hold-down screw having and directly measure and be screwed into the degree of depth in bone, especially can be screwed into the accurate relative location of Cortex Lycii particle for support and hold-down screw junction point distance when orthopedist provides exterior fixation bracket to fix fracture.
Background technology
Exterior fixation bracket is the apparatus that treatment fracture is commonly used, the most screw for metal material of part that itself and bone directly contact or connect, and the structure primitive form of screw can be divided into threadless stylus structure and threaded screw-type structure, and screw-type structure becomes the most frequently used form because it is combined firmly with sclerotin.The polygon staple tail that the exterior fixation bracket screw basic structure applied in current Orthopedic Clinical comprises threaded ailhead, columniform nail bar and can clamp for drill bit.Its mode entered in bone can be divided into screw-in type, in advance drilling self-tapping screw-in type, the self-drilling self-tapping screw-in type again of tapping in advance, and nail bar majority is cylindrical, follows closely tail and mostly is triangle, and minority is tetragon, hexagon, cylindrical.All exterior fixation bracket hold-down screws have not all marked scale, directly can not enter the distance of length in bone and exterior fixation bracket and screw junction point astragalus matter by measuring bolt.Usually, determine that exterior fixation bracket and screw junction point are screwed into the accurate distance of sclerotin position apart from screw, need the length of measuring bolt the position of the good exterior fixation bracket of labelling and screw junction point in advance, to be fixed get well after carry out survey calculation again.This measuring method exist measure inaccurate and exterior fixation bracket readjust after cannot the problem of Measurement accuracy again.
Summary of the invention
For solving above-mentioned technical deficiency, this utility model provides a kind of self-taped type screw with ring gauges, this screw is the utensil that conventional exterior fixation bracket screw combines with dip stick, the length of sclerotin, exterior fixation bracket and screw fixing point to sclerotin can be screwed into be screwed into distance a little by Measurement accuracy screw, for orthopedist accurately locates and the foundation adjusting exterior fixation bracket and provide known.The technical scheme that the present invention solves is: a kind of self-taped type screw with ring gauges, be provided with the nail head (2) that the nail tip (1) of band self tapping groove and threaded length are fixed, be carved with nail bar (3) and the prismatoidal nail tail (4) of ring gauges, it is characterized in that nail tip (1) can along the tapping guide nail head (2) to be screwed in bone voluntarily of pre-bore bone hole, nail bar (3) scale is made up of three groups of camber lines that the length being uniformly distributed in nail bar (3) Zhou Jing is alternate, can reading numerical values from different perspectives, nail tail (4) is prismatic, conveniently firmly be connected with bone drill.
accompanying drawing illustrates:
Fig. 1,2 is structural representation of the present utility model.
This utility model is specifically described by example below in conjunction with accompanying drawing 1,2.
Detailed description of the invention
Self-taped type screw with ring gauges is provided with the nail tip 1 of band self tapping groove and the fixing nail head 2 of threaded length, be carved with the nail bar 3 of ring gauges and prismatoidal nail tail 4, it is characterized in that nail tip 1 can along the tapping guide nail head 2 to be screwed in bone voluntarily of pre-bore bone hole, nail bar 3 scale is made up of three groups of camber lines that the length being uniformly distributed in nail bar 3 weeks footpaths is alternate, can reading numerical values from different perspectives, nail tail 4 is prismatic, is conveniently firmly connected with bone drill.Utilize self tapping to be screwed into fixing, ring gauges measurement, formed the direct Measurement accuracy of the degree of depth being screwed into bone inner bolt.
This utility model has and can be screwed into the length of sclerotin, exterior fixation bracket and screw fixing point to sclerotin and be screwed into distance a little by Measurement accuracy screw, for orthopedist accurately locates and the foundation adjusting exterior fixation bracket and provide known, its have structure simple, easy to operate, measure the advantages such as accurate.
