  • Patent number: 9173649
    Abstract: Embodiments of low profile distractor apparatuses are disclosed. The distractor apparatuses generally comprise a mounting body, a tensioning mechanism coupled to the mounting body and a distractor arm coupled to the tensioning mechanism and pivotally coupled to the mounting body for rotation relative to the mounting body. The tensioning axis of the tensioning mechanism is non-coaxial with an effector axis of the distractor arm and a distraction force applied with the distractor arm is translated to the effector axis. This enables the distractor apparatus to be positioned relative to a patient such that the tensioning mechanism is offset from the long axis of the limb of the patient thereby facilitating improved access to the distal portions of the limb.

  • Patent number: 8845568
    Abstract: Distractor straps for use with distractor apparatuses are disclosed. In one embodiment, a distractor strap includes a cinch strap having a free end and a second end. The second end of the cinch strap includes an adjustment mechanism receiving the free end of the cinch strap such that the cinch strap forms a closed loop. A diameter of the closed loop is adjustable with the adjustment mechanism. The distractor strap further includes a cross strap comprising a first loop, a second loop, and strapping connecting the first loop and the second loop. The cinch strap is positioned in the first loop and the second loop such that the cross strap extends across the diameter of the closed loop formed by the cinch strap and the cross strap and the cinch strap are slidable with respect to one another.
