Abstract: A surgical cutting device includes a handle, a shaft assembly extending distally from the handle, a cutting tool extending through the shaft assembly, and a retractable shield. The retractable shield and/or the cutting tool is movable relative to the other between a retracted position, wherein a distal tip of the cutting tool extends through and distally beyond a ring (or other opening) of the retractable shield, and one or more extended positions, wherein the ring (or other portion) of the retractable shield extends distally beyond the distal tip of the cutting tool. In aspects, a sensor is disposed on a distal face of the retractable shield. In aspects, a surgical system including the surgical cutting device includes control circuitry configured to receive sensed data from the sensor and to provide an output based thereon.

Abstract: Disclosed is a system and method for operating an assembly, such as a powered drill assembly. The assembly may be operated to provide feedback to the user regarding a selected position and/or condition of the powered drill system. The powered drill system may be used to power or drive a selected tool, such as a resection or grinding tool.

Abstract: A drill assembly including a cutting tool slidably movable along a longitudinal axis of the drill assembly and drivable to cut an object. In an active configuration, a pressure loaded drive control assembly transfers energy from a motor to the cutting tool to drive the cutting tool. In an inactive configuration, the pressure loaded drive control assembly prevents energy transfer from the motor to the cutting tool. A biasing member of the pressure loaded drive control assembly is configured to bias the pressure loaded drive control assembly in the inactive configuration. Depressing the cutting tool against the object moves the cutting tool along the longitudinal axis and moves the pressure loaded drive control assembly to the active configuration. The biasing member returns the pressure loaded drive control assembly to the inactive configuration when the cutting tool is no longer depressed against the object.

Abstract: A milling apparatus 2 including an articulated cutter 20 and an inverted L-shaped frame 10 for removing a unique geometric volume of bone to receive a prosthetic implant stem. Cutter 20 is housed within frame 10 for rotational movement about its longitudinal axis and lateral movement along a guide 16, which extends laterally from frame 10. Cutter 20 includes a pair of articulated arms 30, 32 each carrying a plurality of cutting blades 40. The proximal end 22 of cutter 20 is seated in an elongated non-radial race 17 formed in guide 16. Articulated arms 30, 32 provide a "scissoring" action which allows cutter 20 to be compressed longitudinally when shifted to one end of race 17 and extended longitudinally when shifted to the opposite end of race 17. The scissoring action of arms 30, 32 also changes the angle of the cutting face of blades 40 carried by arms 30, 32. Consequently, milling apparatus 2 creates a receiving cavity having an egg-shaped cross section.

Abstract: A surgical reamer assembly for cutting a planar bone surface. The surgical reamer assembly enables the angle or the level of the cutting of the planar reamer to be adjusted. This adjustment is advantageously provided by the use of an adaptor which is positioned between the base support and the planar reamer.

Abstract: A set of hip prosthesis components including a plurality of head components and an adaptor component for use in assembling together one of the head components and a femoral stem component. The first head component is an endo head component having a first bore of a first shape or length. The second head component includes a second bore that is of a second shape or length different from the first shape or length. The adaptor includes an axially extending protruding portion wherein the first shape or length of the first bore is sufficient for the bore to accept and frictionally retain therein the protruding portion. The second shape or length of the second bore is insufficient or inappropriate for the second bore to frictionally retain therein the protruding portion.
