Further, the fore-stock is identical with after-poppet structure, is separating stent-graft；The fore-stock and after-poppet
Include damping sponge and end cap；Integrally formed with the groove for accommodating sponge in the damping sponge.
Further, described sleeve pipe includes pars contractilis and is shaped in the connector portions at pars contractilis two ends；On the end cap
The butt tube being engaged integrally formed with connector portions；The connector portions be sheathed on on butt tube；Described sleeve pipe and fore-stock and
After-poppet is equipped with anchor ear in junction.
Further, the diameter of the through hole on the sponge is slightly less than the diameter of External fixation screw；In the minimum of described sleeve pipe
Footpath is slightly larger than the diameter of External fixation screw；Diameter of the fixed pin perforation slightly larger than External fixation screw on the fore-stock and after-poppet.
Beneficial effect：The present invention it is a kind of applied to orthopedic external fixation needle it is anti-lose sterile sleeve device by sleeve and
The sponge for being impregnated with thimerosal carries out proofing dust and protecting and Quick disinfection to External fixation screw, and the guiding of after-poppet is realized simultaneously by guide rod
And fixed support can integrally be reinforced, the sliding support and fore-stock on guide rod coordinate the water ensured between guide rod
Pingdu, the effective outside torsion of resistance is finally provided with the anti-of effect to External fixation screw and loses protection on support bracket fastened influence.
