Abstract

The invention provides a combined light source system for photodynamics therapy. The system comprises a therapy head front cover and a therapy head back cover; a transmittance protection glass plate,an optical shaping lens array, an optical shaping lens array mounting plate, an irradiation light source integration plate and an irradiation light source cooling device are mounted between the therapy head front cover and the therapy head back cover in sequence; as the optical shaping lens array is adopted, the irradiation power density is high, the irradiation area is large, the output energy isstable, the irradiation surface energy density uniformity is good, and the irradiation light wavelength is stable; a laser distance measuring probe is provided for measuring the distance from the combined light source system to a therapy part, so that the therapy quality is guaranteed, and the problems of burn of the patient skin due to nearer distance and influence on the therapy effect due to farther distance are prevented; the irradiation light source cooling device is provided for cooling to prevent burnout of an irradiation light source; and a laser is indicated to emit converted indication light rays for precisely positioning the therapy part.

Description

technical field [0001] The invention relates to a light source system, in particular to a combined light source system for photodynamic therapy. Background technique [0002] With the progress and development of medical science, the use of specific wavelengths of light and matching photosensitizers is used to treat diseases by light irradiation: Photodynamic Therapy is called photodynamic therapy, referred to as (PDT) therapy. It has been widely used in the treatment of dozens of diseases such as dermatology, gynecology, venereal diseases, and oncology. It has unique advantages such as non-invasive, non-toxic and side effects, significant curative effect, and low treatment risk, and is well received by doctors and patients. [0003] The light source for photodynamic therapy is the core and key of photodynamic therapy. The existing light source has low irradiation power density, small irradiation area, and unstable output energy, which cannot meet the needs of treatment. C...
