我院现正使用的英国ＤＩＯＭＥＤ／６０型半导体激光刀，在进入临床手术前，以动物为实验体的不开放性手术中，激光纤维头的不锈钢护套温度上升很快，而且随着激光刀输出功率的增大，温度随之升高。当将输出功率调为４０Ｗ时，不超过３０s，护套温度就会上升７０℃左右（用三只 The British DIOMED/60 type semiconductor laser knife currently being used in our hospital, before entering the clinical operation, in the open surgery using animals as the experimental body, the temperature of the stainless steel sheath of the laser fiber head rises quickly, and the output power of the laser knife increases. As the temperature increases, the temperature increases. When the output power is adjusted to 40W, the temperature of the sheath will increase by about 70°C for no more than 30 seconds (with three
