Hemostatic thermal sealer

A hemostatic sealer, comprising:

• a cordless handpiece having a source of energy, a handle, and a thermal assembly including:
• an electrically insulative and thermally insulative smooth and blunted substrate, and
• an electrically resistive material plated as a smooth exposed plating surface along a length of the substrate,
• the thermal assembly comprising a blunted rectangular prism having a top generally planar face and an opposing bottom generally planar face;
• the handle having a binary activation switch to activate the source of energy, the handle configured to be held in a user's hand and operated to control one function of the hemostatic sealer
• a rigid shaft extending axially and distally from the handle, the shaft including a distal end;
• and
• the thermal assembly coupled to the distal end of the rigid shaft via a first tab projecting proximally from the top face, and a second tab projecting proximally from the bottom face, wherein the first and second tabs are couplable to electrical conductors within the rigid shaft such that electrical current is passed through the resistive material between the first and second tabs to heat the thermal assembly, the thermal assembly having a length from the distal end, the substrate having a width, the resistive material operably extending from the width of the substrate and coupled to the switch to receive energy from the source of energy, the hemostatic sealer not including a fluid outlet port such that the thermal assembly is configured to provide hemostatic sealing of bone or tissue without application of fluid.
