Abstract: An implant extractor that includes an elongated body having a proximal end for attachment to an extraction device, a first arm extending from the elongated body, and a second arm pivotably connected to the first arm. The second arm includes a moment arm for generating a torque about a distal end of the second arm. The implant extractor further includes a force applicator operatively connected to the first arm and the moment arm to apply a force to one or more of the first and second arms.

Abstract: A surgical hammer that includes a handle, a shaft extending from the handle and a hammer head connected to the shaft. The hammer head includes a slot extending through the hammer head and in fluid communication with a distal end of the hammer head, a first internal cavity within the hammer head spaced laterally from the slot, and a second internal cavity within the hammer head spaced laterally from the slot.

Abstract: An implant extractor assembly that includes a handle, and a mount connectable to the handle. The mount includes a main body, a quick connect about a proximal end of the main body, and an L-shaped connector about a distal end of the main body. The L-shaped connector includes a through hole having a longitudinal axis transverse to a longitudinal axis of the main body.

Abstract: A handle for a surgical tool including a shaft having a proximal end and a distal end with a gripping handle affixed to the proximal end of the shaft. A bushing is attached to the distal end of the shaft, the bushing including a plurality of flexible members circumferentially spaced apart. The handle further includes a sleeve circumscribing the shaft and the bushing. The sleeve is moveable between a first position substantially covering an entirety of the bushing and a second position spaced from a most distal end of the bushing.

Abstract: An implant extractor for use in orthopedic surgeries. The implant extractor provides a line of force substantially parallel to an implant to be extracted. The implant extractor includes a curved body having a curved jaw track configured to slidingly receive a correspondingly curved jaw for clamping a trunnion of an implant, e.g., a hip stem implant. A push rod urges the curved jaw into clamping engagement with the trunnion under the influence of a cam handle having a continuously curved cam surface.

Abstract: A handle assembly for a surgical tool including a handle having a distal end, and a first retaining mechanism attached to the distal end of the handle. The retaining mechanism includes a first retaining housing having a first central cavity for receiving a surgical tool, and a first locking mechanism moveable between first and second positions relative to the housing, the locking mechanism including a through hole for receiving the surgical tool. The handle assembly further includes a second retaining mechanism attached to a proximal end of the handle. The second retaining mechanism includes a second retaining housing having a second central cavity for receiving a handle extension, and a second locking mechanism moveable between first and second positions relative to the second retaining housing, the second locking mechanism having a through hole for receiving the handle extension.

Abstract: An implant extractor tool including first and second pivotably connected arms having jaws at their distal ends adapted to engage an implant. The tool further includes an adjustment mechanism having an adjuster and a biasing member biasing one of the first and second arms, and an actuator operatively engageable with the adjustment mechanism. The actuator is movable between a first position locking the adjustment mechanism in a fixed position and a second position spaced from the adjustment mechanism permitting movement of the adjustment mechanism relative to the actuator. The implant extraction tool can be operated using one hand to engage an implant to be extracted.

Abstract: A modular jaw for attachment to an orthopedic implant extraction tool that includes an elongated body, a claw about a distal end of the elongated body for engaging an object, and a locking mechanism about a posterior end of the elongated body for engaging the orthopedic implant extraction tool. The locking mechanism includes a dovetail lock, a detent mounted to the dovetail lock, and a distally facing surface about a proximal end of the elongated body.
