  • Patent number: 5443464
    Abstract: An external fixation system for stabilizing bone fractures is provided, having a hexagonal rod as the primary support mechanism with a plurality of fixation components adjustably secured thereto. The fixation components preferably include at least one pin secured to the hexagonal rod by a clamping mechanism which provides multiple degrees of adjustability for enhanced pin placement. The clamping mechanism comprises a clamp member and ball collet having a hexagonal opening formed therein, wherein the ball collet fits within a cavity in the clamp member with the rod extending therethrough, and a retaining nut used to compress the ball collet thereby grippingly engaging the rod and securing the clamp member to the rod. The clamp member is adjustable to any desired position both longitudinally and peripherally about the rod. Each pin is secured within a clamp member through the use of similar ball collets and retaining nuts, and is angularly adjustable relative to the clamp member.

  • Patent number: 5360020
    Abstract: The pin site shield having a separate sponge and retainer removably securable to an orthopedic pin, wire, or similar implement. The retainer comprises a body having a slot form therein for receiving the orthopedic pin and a clamping member hingedly secured thereto. The clamping member is selectively moveable between open and closed positions, with interlocking surfaces on the body and clamping member engaging one another when the retainer is in its closed position to secure the retainer at its appropriate position on the pin. Protrusions on the body and clamping member allow installation of the retainer by squeezing the protrusions between a thumb and forefinger, with removal of the retainer being effected by spreading the protrusions apart.
