Abstract
An improved external fixation device composed of a plurality of fixation rings, multiple tie rods, and pin holders which cooperate to immobilize a bone fracture. An improved composite fixation ring having a core of a resin matrix reinforced with fibers is covered with a braided sleeve with resin impregnating the sleeve and the core.
Claims
AMENDED CLAIMS
[received by the International Bureau on 18 September 1997 (18.09.97); original claims 1-11 cancelled; new claims 13-18 added; remaining claim unchanged (2 pages)]
12. In an external fixation device for immobilizing a bone fracture that includes a plurality of external fixation rings, a plurality of pins anchored to the bone and clamped to the fixation rings and lockable adjustment rods interconnecting the fixation rings, the improvement comprising: said fixation rings being a unitary composite structure that includes a core of a resin matrix reinforced with fibers, a fiber material covering said core and a resin impregnating said fiber material.
13. The external fixation device of claim 12, the fixation rings being unitary composite structures wherein the core fibers are oriented in transverse and non-transverse directions with respect to the longitudinal axis of the article.
14. The external fixation device of claim 12, wherein said fiber material covering said core is a braided sleeve.
15. The external fixation device of claim 13, wherein said fiber material covering said core is a braided sleeve.
16. The external fixation device of claim 12, wherein said core comprises a curved I-beam cross- section having flanges and a web and a longitudinal axis said core fibers include unidirectional fibers within said flanges and further include layers of material forming said web, said unidirectional fibers being aligned generally parallel to the longitudinal axis of the core and to said layers of material, and wherein said layers of material include fibers, said fibers within said layer being oriented between about ± 45 degrees ± 15 degrees relative to the longitudinal axis of the core, the angles being balanced in the positive and negative directions.
17. The external fixation device of claim 16, wherein said fiber material covering said core
comprises braided or wound continuous filament tow and wherein the braid or winding angles are between about ± 45 degrees ± 15 degrees relative to the tangent of the longitudinal axis through the centroid of the core. 18. The external fixation device of claim 12, wherein said fiber material are carbon fibers said resin material is epoxy resin.
