A method for reducing damage caused by dispersed liquid nitrogen spraying of a laser therapeutic apparatus is characterized in that the device for dispersing liquid nitrogen spraying of the laser therapeutic apparatus is the device for dispersing liquid nitrogen spraying of the laser therapeutic apparatus according to any one of claims 1 to 7, and comprises a guide plate (8), wherein the bottom of the guide plate (8) is supported by two support columns (7), a plurality of auxiliary tubes (9) are arranged at the top end of the guide plate (8) at equal intervals, so that the flow rate of liquid nitrogen can be effectively reduced, the liquid nitrogen with the reduced flow rate is continuously conveyed into a rubber sleeve (18) through a buffer frame (6), the flowing speed of the liquid nitrogen is further reduced, and the skin damage caused by the overlarge impact force of the liquid nitrogen with the excessively high speed on the skin is avoided.
9. The method for reducing damage by dispersing liquid nitrogen of a laser therapeutic apparatus according to claim 8, wherein the plurality of circular holes (10) are used for changing large liquid nitrogen drops into a plurality of small liquid nitrogen drops and dispersing the liquid nitrogen drops, and the rubber sleeve (18) is clamped by the limiting hook (16) to limit the rubber sleeve (18) on the same straight line, so that the phenomenon that the flowing speed of the liquid nitrogen drops is influenced by overlarge bending between the rubber sleeve (18) and the supporting tube (1) is avoided.
