Novel reflecting laser microsurgery adapter

The utility model relates to a novel reflecting laser microsurgery adapter. The adapter is characterized in that a main lens cylinder is disposed at the front end of a cavity of a laser adapter body, a small hole is formed in the center of the main lens cylinder, a hand wheel is sleeved on the laser adapter body, a spiral groove is formed between the hand wheel and the laser adapter body, the front end of a connection protective cover is fixedly connected with the rear end of the laser adapter body through a lock nut, a connection seat is fixedly connected with the outer wall of the connection protective cover, and a microscopy interface and an auxiliary lens seat are fixedly connected with the rear end of the connection protective cover. A main lens small hole is formed in the center of a concave main lens a which is fixedly connected with the main lens cylinder through a main lens compression ring, and a protruding auxiliary lens b is connected onto an auxiliary lens seat through an auxiliary lens compression ring. By means of the adapter, CO2 laser can be transmitted to disease positions to treat the positions, the function of laser beam focusing and steering is provided, the adapter is simple in structure, easy to operate, low in production cost, free of aberration and capable of guaranteeing the consistency between indication red light and the CO2 laser focus.
