International ClassA61N 005/06AbstractA method for carrying out surgical procedures using a laser and a laser surgical tool includes the provision of a temperature control device associated with the laser which monitors the temperature of the surgical tool and delivery system and governs the laser power output to achieve a desired temperature level. The temperature control device may be used either to prevent heating of the surgical tool and delivery system beyond it structural tolerance, or to maintain a predetermined temperature level which is optimized for a particular surgical or medical procedure. The delivery system may comprise an optical fiber, and the surgical tool may comprise the output end of the optical fiber which is free of any additional surgical cutting implement. | |
