Abstract: An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.

Abstract: A device for retracting a patient's tissues. More specifically, a surgical retractor is provided which can be easily inserted through an incision in a closed position, and opened to radially actuate a plurality of fingers in contact with the incision to desirably provide 360 degree access to, and visualization of, an operative field. The surgical retractor comprises a housing, a rotatable adjuster mounted to the housing, and a plurality of dilators received in the housing and operatively connected to the rotatable adjuster. Each dilator includes a scroll gear radially movable in the housing, and a finger extending from the scroll gear.

Abstract: A surgical retractor including a first retractor arm, a second retractor arm, and a third retractor arm coupled with the first retractor arm and the second retractor arm to move in tandem therewith is disclosed. The first retractor arm and the second retractor arm pivot about a single axis of the surgical retractor.

Abstract: An implant extractor for extracting an implant from bone comprising a housing, an adjustment mechanism within the housing, an outer sleeve extending from the housing, an inner shaft within the outer sleeve and having a proximal end operatively engaged with the adjustment mechanism, and a clamp operatively engaged with distal ends of the inner shaft and the outer sleeve.

Abstract: An arthroscopic washer extractor including a handle, an actuator pivotable relative to the handle and movable between a neutral position and a retracted position, a shaft operatively connected to the actuator, and a pair of jaws at least one of which is operatively connected to the shaft, wherein each of the pair of jaws includes a radially outwardly extending flange, and wherein when the actuator is in the retracted position the pair of jaws move to an expanded state operable to engage an arthroscopic washer.

Abstract: A cutter for cutting an implant is provided. The cutter includes a gearbox; a primary milling bit, a secondary milling bit and a lead screw operatively coupled to the gearbox; an input coupling coupled rigidly to the primary milling bit; and an implant coupler coupled rigidly to the lead screw, wherein the gearbox is operable to translate with respect to the lead screw and to drive the secondary milling bit in response to a driving force applied to the input coupling.

Abstract: A tool drive assembly including a flexible drive shaft and a guide. The flexible drive shaft includes a proximal end structured to engage a driver for rotating the flexible drive shaft, and a distal end opposite the proximal end. The guide includes a handle, a shaft extending from the handle, and a hub assembly at a distal end of the shaft. The hub assembly includes a housing, and a hub rotatably mounted within the housing. The hub includes an input connection structured to attach to the distal end of the flexible drive shaft, and an output connection structured to attach to a working tool. The tool drive assembly enables easy manipulation and driving of a working tool to achieve optimum positioning and effectiveness of the working tool.

Abstract: A gouger grasper device including a handle at a proximal end of the device, the handle having a base and a trigger movably connected to the base, a chisel at a distal end of the device, a jaw at a distal end of the device and movable relative to the chisel, and a ratcheting assembly for moving the jaw relative to the chisel between an open position and a clamping position in response to movement of the trigger relative to the base.

Abstract: An intramedullary nail extractor including a central body, a rotatable sleeve and a clamping member. The central body includes a proximal end for attachment to an extractor, a distal end having a hook for engaging an intramedullary nail, and a threaded intermediate portion between the proximal end and the distal end. The rotatable sleeve threadedly engages the threaded intermediate portion of the central body, and the clamping member is operatively engaged by the rotatable sleeve and moveable relative to the central body.

Abstract: A surgical extractor including first and second arms connected to first and second implant-engageable jaws. The first and second arms are connected by first and third links to a stationary screw jack nut and by second and fourth links to a moveable screw jack nut. A driven shaft is rotatably received in the stationary screw jack nut and threadedly received in the moveable screw jack nut, and a drive shaft rotatably drives the driven shaft. Rotation of the drive shaft in a first direction separates the first and second arms and jaws in order to receive an implant. Rotation of the drive shaft in a second direction closes the first and second arms and jaws in order to clamp an implant. A handle assembly engages the drive shaft in order to drive the drive shaft and disengages from the drive shaft to exert a removal force on an implant.

Abstract: A surgical extractor that includes a first arm and a second arm, a linkage assembly connected to the first and second arms, and a driven shaft operatively engaged with the linkage assembly for moving the linkage assembly between first and second positions. The surgical extractor further includes a tensioning shaft engageable with the driven shaft for moving the driven shaft relative to the linkage assembly.

Abstract: A spine rod cutter including a helicopter socket for engaging a spine rod, and a hole saw coaxial with the helicopter socket for operatively engaging the spine rod.
