Surgical saw blade and thermal management system
A surgical saw blade thermal management system including a saw blade and blade mount. The saw blade including a cutting edge, a proximal portion, and a body portion. The cutting edge has teeth and is substantially formed of a first material having a first thermal conductivity. The proximal portion includes a blade hub. The body portion disposed between and connecting the cutting edge and the proximal portion and including a thermal transit core formed of a second material having a second thermal conductivity at least twice the first thermal conductivity and the core having at least two opposed longitudinally extending first core surfaces extending across a width of the core, and at least two longitudinally extending flanking members with each disposed over the longitudinally extending first core surfaces. The blade mount including a heat sink and is configured to receive the blade hub.
1 . A surgical saw blade thermal management system comprising:
a surgical saw blade comprising:
a cutting edge including a plurality of teeth substantially entirely formed of a first material having a first thermal conductivity,
a proximal portion including a blade hub, and
a body portion disposed between and connecting the cutting edge and the proximal portion and including a thermal transit core formed of a second material having a second thermal conductivity at least twice the first thermal conductivity the thermal transit core having at least two opposed longitudinally extending first core surfaces extending across a width of the thermal transit core, and
at least two longitudinally extending flanking members with each disposed over the longitudinally extending first core surfaces; and
a blade mount in receipt of the blade hub and connected to a saw hand piece and including a heat sink.
2 . The surgical saw blade thermal management system of claim 1 , wherein the heat sink is a passive heat sink including a plurality of fins extending from a heat sink base.
3 . The surgical saw blade thermal management system of claim 2 , wherein the heat sink further comprises a fan configured to move air across the fins.
