<p>Apparatus and software for controlling an intraoperative temperature at a wound site is described. The apparatus comprises a control system having, i) a control console (14,114,214,314,414,514,714) having a control module including the central processing unit (16,116,216,316,416,516,716); ii) a handpiece power supply (20,120,220,320,420,520,720) and iii) a means for measuring infusion fluid flow (22,122,222,322,422,522,722). In order to control an intraoperative temperature at a wound site means are provided for; a. selecting a desired intraoperative wound site temperature; b. providing infusion fluid flow information to the control module; c. providing handpiece power information to the control module from the handpiece power supply; d. calculating a current temperature at the would site based on current and previous values of infusion fluid flow and handpiece power; e. comparing the calculated current temperature at the wound site with the selected desired intraoperative wound site temperature; and f. varying the operation of the handpiece power supply based on the comparison between the calculated current temperature at the wound site with the selected desired intraoperative wound site temperature. <IMAGE></p> |
