Description
Technical Field
The utility model belongs to the technical field of medical equipment, and particularly relates to a laser therapeutic apparatus.
Background
The photodynamic therapy apparatus is a physical therapy apparatus for treating some diseases by utilizing light, and the mechanism of the photodynamic therapy of the diseases mainly utilizes the photobiological effect. Human tissue cells respond to light of specific wavelengths, such as: mitochondria in cells are most absorbed by red light, and can improve local blood circulation and enhance local immune function in a relatively short time. Can also accelerate the metabolism of local tissues to cause a series of benign reactions, such as promoting the regeneration of local squamous epithelium, repairing skin lesions, enhancing the absorption of local inflammatory exudates, relieving local muscular tension, and promoting the healing of wounds.
The photodynamic therapy apparatus is used in combination with a medicament (the medicament contains a photosensitizer or a metabolite is the photosensitizer), so that photodynamic therapy for directionally killing abnormal cells can be realized. For example: after entering into somatic cells, exogenous ALA can be enriched in abnormal cells (tumor cells, HPV infected cells, inflammatory cells and the like) and is converted into porphyrin substances such as protoporphyrin IX and the like in the cells, the protoporphyrin IX is a strong photosensitizer, and active oxygen is generated after being irradiated by light with specific wavelength to destroy a biological membrane structure in the cells and lead target cells to be necrotic and apoptotic, so that the purpose of directionally killing the abnormal cells is realized, and the specific photosensitizer can treat the following diseases: beriberi, periodontitis, skin ulceration, herpes, dermatitis, etc.
Photosensitizers are generally sensitive to light wavelengths and require a certain light intensity to undergo a photosensitizing reaction, resulting in effective photodynamic therapy. The conventional photodynamic therapy apparatuses on the market can be roughly divided into two types: one uses a thermal light source or an LED as a light source, and has wide spectrum range, low actual effective energy, light spot divergence, low illumination intensity and general actual treatment effect; the other type uses laser as a light source, has the advantages of narrow spectral range, high efficiency, concentrated light spots, high illumination intensity and the like, wherein the semiconductor laser light source is used in batch by virtue of the advantages of low cost, no maintenance and the like. However, the semiconductor laser light source has a disadvantage that the wavelength shifts with temperature, and the output wavelength becomes longer with increasing temperature, and the effective energy decreases, for example: the photoacid generator can play a photodynamic role on the laser of 630 +/-3 nm, and the AlGaInP semiconductor laser tube can drift from 632nm to 641nm along with the rise of temperature, so that the treatment effect is reduced.
The semiconductor laser therapeutic apparatus has the defect that the wavelength drifts along with the temperature, and the therapeutic effect of external application or oral administration medicine related to photodynamic therapy is unstable (the photosensitizer selectively absorbs the wavelength); the optimal effect can not be achieved by controlling the output wavelength in a small range according to different used medicines. The output part adopts simple lens coupling, the illumination range and the intensity can not be directly adjusted, and the treatment effect is also reduced.
