| 摘要 |
<p>The invention relates to an improved unilateral telescopic external fixator (10) comprising a telescoping unit (11) which includes telescopically engaging inner and outer parts (12, 13) arranged for limited axial reciprocal movement relative to one another along the longitudinal axis of the unit, the outer part (12) having a central bore extending therethrough, the inner part (13) engaging with sliding fit in the bore and extending the full length thereof, the inner part (13) being non-rotatable about said axis, wherein the bore comprises hard polymeric material whilst the inner part (13) is preferably formed of metal, a pair of orthopaedic pin clamp assemblies (20), one of which is carried by the inner part (13) adjacent its proximal end, the other being adjustably carried on the outer part (12) for selective positioning along the length thereof, and releasable locking means (60) for releasably locking said parts (12, 13) against said axial movement.</p> |
