Semiconductor laser therapeutic instrument power correction system and method

Abstract

The invention relates to a semiconductor laser therapeutic instrument power correction system and method, and belongs to the technical field of medical instruments. The system comprises a man-machineinteraction module, a 32-bit ARM microcontroller, a DA conversion module, a laser output control module, a power feedback module, and a laser device module, wherein after the man-machine interaction module selects a laser tube needing to be corrected and presets a power value, an actual laser device output power value is tested, and when the actual measurement value is inconsistent with a preset value, the required power value is adjusted and corrected through a key for correction. According to the invention, accurate correction of the laser power of the semiconductor laser therapeutic instrument can be realized only through human-computer interface adjustment without opening equipment, so that the problem of inaccurate and inconvenient correction of the laser power of the semiconductor laser therapeutic instrument in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a power correction system and method for a semiconductor laser therapeutic instrument. Background technique [0002] Laser is a new type of light source that appeared in the 1960s. It has the characteristics of strong directionality, high brightness, monochromaticity and good coherence. In 1961, the United States used a ruby ​​laser to weld the peeled retina, which opened the prelude to the use of lasers in biology and medicine. At present, laser has been widely used in medical diagnosis and treatment. It can treat more than 300 diseases including ophthalmology, gynecology, dermatology, internal medicine and oncology. Laser therapy can generally be divided into three categories: laser surgery, weak laser therapy, and photodynamic therapy. Laser therapy has light effects and thermal effects, which can promote the diffusion and absorption of inflammation. Local irradiation...
