Surgical tool guard

A surgical system comprising:

• a rotary tool comprising an elongated member and an energy applicator disposed at a distal end of the elongated member;
• a surgical device configured to receive and rotatably drive the rotary tool;
• and
• a guard for the rotary tool, the guard comprising:
• a body including:
• a proximal end and a distal end opposite the proximal end, the proximal end configured to connect to the surgical device, and a longitudinal portion located between the proximal end and the distal end;
• an interior surface defining a bore extending between the proximal end and the distal end and the bore adapted to receive a friction reduction element configured to retain the elongated member therethrough, and the friction reduction element defining a first longitudinal length;
• an exterior surface extending between the proximal end and the distal end and encompassing the interior surface between the proximal end and the distal end;
• and
• at least one thermal mitigation channel located between the interior surface and the exterior surface adjacent to the friction reduction element and extending a second longitudinal length spanning at least the first longitudinal length, the at least one thermal mitigation channel opening through a plurality of ports arranged as an array on the exterior surface, the array being located on the longitudinal portion and being arranged within the second longitudinal length, wherein the at least one thermal mitigation channel and the plurality of ports are configured to dissipate heated air or gas from the body in response to the surgical device rotatably driving the rotary tool and wherein the longitudinal portion includes a segment adjacent to and non-overlapping the at least one thermal mitigation channel, the segment comprising solid material fully extending between the interior and exterior surface.

A robotic system comprising:

• a rotary tool comprising an elongated member and an energy applicator disposed at a distal end of the elongated member;
• a surgical device configured to receive and rotatably drive the rotary tool;
• and
• a surgical robot configured to support and move the surgical device;
• and
• a guard for the rotary tool, the guard comprising:
• a body including:
• a proximal end and a distal end opposite the proximal end, the proximal end configured to connect to the surgical device, and a longitudinal portion located between the proximal end and the distal end;
• an interior surface defining a bore extending between the proximal end and the distal end and the bore adapted to receive a friction reduction element configured to retain the elongated member therethrough, and the friction reduction element defining a first longitudinal length;
• an exterior surface extending between the proximal end and the distal end and encompassing the interior surface between the proximal end and the distal end;
• and
• at least one thermal mitigation channel located between the interior surface and the exterior surface adjacent to the friction reduction element and extending a second longitudinal length spanning at least the first longitudinal length, the at least one thermal mitigation channel opening through a plurality of ports arranged as an array on the exterior surface, the array being located on the longitudinal portion and being arranged within the second longitudinal length, wherein the at least one thermal mitigation channel and the plurality of ports are configured to dissipate heated air or gas from the body in response to the surgical device rotatably driving the rotary tool and wherein the longitudinal portion includes a segment adjacent to and non-overlapping the at least one thermal mitigation channel, the segment comprising solid material fully extending between the interior and exterior surface.
