Abstract

The invention relates to a picosecond laser therapeutic machine laser output detection and laser termination device and method. A man-machine operation interface is connected with an RS232 communication circuit; the RS232 communication circuit is connected with a single-chip microcomputer and a peripheral control circuit; the single-chip microcomputer and the peripheral control circuit are connected with a photoelectric coupled isolate circuit, a Hall sensor and a laser; the photoelectric coupled isolate circuit and the Hall sensor are connected with a photoelectric coupled isolate circuit; the photoelectric coupled isolate circuit is connected with a laser termination circuit; and the laser termination circuit is connected with the photoelectric laser. The method comprises the following steps of detecting the laser output state by the photoelectric laser output detection circuit through the Hall sensor; judging whether the photoelectric laser output state is correct or not through treatment by the single-chip microcomputer and the peripheral control circuit; and if abnormal state is generated, directly stopping laser output through the photoelectric laser output detection circuitand the laser termination circuit, so that the using safety of the user is guaranteed. Through the adoption of the photoelectric laser therapeutic machine laser output detection and laser terminationdevice disclosed by the invention, under the photoelectric laser out-of-control state, the laser output circuit can be cut off.

Description

technical field [0001] The invention relates to a laser output detection and laser termination device and method of a picosecond laser treatment machine, in particular to an automatic laser output protection device for a picosecond laser treatment machine, which can cut off the laser output circuit when the picosecond laser is out of control . Background technique [0002] Before the present invention was made, the equipment and instruments that used picosecond laser for treatment on the market could not satisfy the closed-loop control of picosecond laser, but only controlled the opening and closing of picosecond laser. Once the picosecond laser was out of control, the picosecond laser would always output , causing harm to users.
