Abstract: An orthopedic instrument in the form of an acetabular cup extractor for reliably and efficiently extracting an acetabular cup implant from an acetabulum. The acetabular cup extractor includes a handle assembly and a quick connect coupling extending from the handle assembly. The acetabular cup extractor further includes a blade having a first quick connect for connecting with the quick connect coupling and a second quick connect. In addition, the acetabular cup extractor includes a guide configured to be received within an acetabular cup, the guide including a quick connect coupling for connecting with the second quick connect of the blade.

Abstract: A cutter for cutting an implant is provided. The cutter includes a handle; a handle coupler coupled to the handle; a drill guide coupled to the handle coupler and including at least one window; a mill extending through the handle coupler and the drill guide and disposed to rotate freely therein; and a catch cup circumscribing the drill guide to maintain chips of the implant removed by the mill.

Abstract: A surgical tool assembly having a striking assembly is disclosed. The surgical tool assembly includes a handle for attachment to a tool, and a striking assembly for attachment to the handle. The striking assembly includes a frame, an impact plate extending from the frame, and a guard attached to the frame and movable between a first position adjacent the frame and a second position. The second position may be distal to the frame, e.g., adjacent the handle.

Abstract: A locking grip extraction tool has plier handles with jaws having sharp beveled edges for moving in a direction so that an axis perpendicular to the plane of movement is oriented at an acute angle to the handles; the axis intersecting the plane of jaw movement at a point midway between the jaws. A locking link coupled to the handles is adapted to releasably lock the jaws onto an orthopedic implant. A connection rod can be threaded into a hole in one of the handles near the jaws, so that a force applying tool such as a slap hammer can be connected to the rod to apply force to remove the implant. The rod is in alignment with the axis, which alignment makes it easier to remove the implant.

Abstract: An osteotome guide is provided. The osteotome guide includes a handle, a shaft within the handle and slidable to a selected longitudinal position with respect to the handle, a tool coupler attached to a distal end of the shaft for receiving a working tool, and a lock assembly to lock the shaft into the selected longitudinal position with respect to the handle.

Abstract: A trephine is provided. The trephine includes a hole saw sized to accommodate an implant, the hole saw having: a cylindrical body having a proximal end, a distal end and an outer surface, a plurality of circumferentially spaced cutting teeth at the distal end of the cylindrical body, and a plurality of helical grooves on the outer surface of the cylindrical body; and a quick connect coupled to the proximal end of the cylindrical body for releasably connecting to a cooperating quick connector of a tool.

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 including a shaft body and a telescoping push rod extending from the shaft body. An adjustor is engaged with the telescoping push rod for adjusting a length of the telescoping push rod. A support arm extends laterally away from the shaft body and a jaw assembly extends from the support arm. The jaw assembly includes a jaw moveable between a locking position and an unlocking position, and a rocker arm operatively engaged with the telescoping push rod and the jaw. The implant extractor provides a line of force spaced from and substantially parallel to an implant to be extracted. As a consequence, there is substantial clearance for an extension handle such as a C-frame or the like which is oftentimes needed to dislodge the implant from surrounding bone. In addition, the implant extractor is capable of gripping a wide range of sizes of hip stem implant trunnions.

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 chuck assembly for a medical device is provided. The chuck assembly includes a mounting base structured to couple to a tool; a housing coupled to the mounting base; and a cam sleeve within the housing and movable with respect to the housing between a locked position and an unlocked position, the cam sleeve having an annular base, an arm extending from the annular base, and a cam extending laterally from the arm.
