Abstract: A surgical clamp assembly for clamping tissue and supporting a navigation tracker. The assembly includes a clamp body. Clamp arms are coupled to the clamp body to grip tissue. At least one of the clamp arms includes a distal portion having a clamp surface to grip tissue and a proximal portion that is pivotable relative to the clamp body about a first pivot. A linear displacement mechanism and a carrier are coupled to the clamp body. The carrier is moveable relative to the clamp body along a carrier axis in response to movement of the linear displacement mechanism. The carrier is coupled directly to the proximal portion of the clamp arm. The clamp arm is also pivotable relative to the carrier about a second pivot in response to movement of the carrier.

Abstract: A guard for a tool. The tool is actuatable by a surgical device and has an elongated member and an energy applicator disposed at a distal end of the elongated member. The guard may have a monolithic body including a proximal end and a distal end opposite the proximal end. The proximal end connects to the surgical device. The body further has an interior surface defining a bore extending between the proximal and distal end and the bore adapted to receive the elongated member therethrough and an exterior surface extending between the proximal and distal end and encompassing the interior surface between the proximal and distal end. The body has at least one thermal mitigation channel located between the interior and exterior surfaces and opening through at least one port in the exterior surface.

Abstract: A clamp assembly fixes a navigation tracker to a bone. The assembly includes first and second clamp jaws. The second clamp jaw is pivotal about a first fixed pivot. A linear driver includes a shaft. A first linkage is pivotal at one end about a second fixed pivot and coupled at an opposing end to the shaft at a first moving pivot. A second linkage is coupled at one end to the shaft at the first moving pivot and coupled at the other end to the second clamp jaw at a second moving pivot. The linear driver linearly translates the shaft to apply force to the first moving pivot in a first direction to pivot the second clamp jaw towards the first clamp jaw and in a second direction opposite to the first direction to pivot the second clamp jaw away from the first clamp jaw.
