摘要： A surgical dissection tool for cutting bone and other tissue includes a cutting head having an outer surface having non-paired or an odd number of flutes formed therein. Each flute includes a rake surface intersecting with the outer surface to form a cutting edge, and a relief surface opposite the rake surface. The relief surface and the rake surface form a first angle. Each flute also includes a leading angled surface extending from the relief surface to a distal end portion of the cutting head, the leading angled surface and the rake surface forming a second angle substantially the same as the first angle.

摘要： A surgical bur includes a body and a drill point. The body includes flutes and lands. Each of the flutes includes a cutting edge, a rake face, and a clearance surface. Each of the lands is convex-shaped and disposed between a pair of the flutes. The drill point includes axial relief surfaces. Each of the axial relief surfaces has a planar area, is distinct from the lands and borders (i) a distal portion of one of the cutting edges, (ii) one of the lands, and (iii) one of the clearance surfaces.

摘要： 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.
