1. A thermal surgical instrument comprising:
- a body comprising a body housing, a first conduit disposed in the body housing, and a fluid connection site disposed in fluid communication with the first conduit;
a surgical tip comprising a tip housing and a hollow thermal element extending from the tip housing;
wherein the surgical tip is in communication with the body housing such that at least a portion of the surgical tip is in fluid communication with the first conduit; and
wherein the first conduit, the body housing, and the hollow thermal element form a coolant flow pathway for cooling the thermal surgical instrument.

Abstract
A cooling system for a surgical handpiece may provide fluid flow to the surgical tip and to the internal electronic components to prevent temperatures that may damage or make the patient or surgeon uncomfortable. Tip directed gas further controls the tip-tissue interface by displacing blood or serum from the incision point, increasing precision and diminishing coagulum build-up. In the alternative, cooling fluid may be used to quench tissue being treated.

13. A method of cooling a thermal surgical instrument comprising the steps of:
-
selecting a thermal surgical instrument comprising a ferromagnetic thermal element, a housing having a coolant flow pathway, and a fluid connection site, the housing having a tip housing and the ferromagnetic thermal element extending outwardly from the tip housing; connecting the fluid connection site to a device to provide a cooling fluid to the thermal surgical instrument; and directing cooling fluid through the coolant flow pathway to remove heat from the thermal surgical instrument. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method of cooling a surgical handpiece comprising:
-
causing a coolant to flow through an inside first portion of a tip; reversing the direction of the coolant flow adjacent the first portion of the tip; and causing the coolant to flow through an inside second portion of the tip.
