Optical power therapentic equipment

Abstract

The invention provides a photodynamic treatment device, which includes a treatment light source, a fluorescence exciting light source, a light-coupling module, an optic fiber interface, a fluorescence analyzing module, and a core control module. The treatment light source and the fluorescence exciting light source are both connected to the light-coupling module, the light-coupling module couples the obtained two routes of light to the optic fiber interface for outputting, the light-coupling module sends the fluorescence which is sent back by the optic fiber interface and is filtered to the fluorescence analyzing module. The fluorescence analyzing module transmits analysis data to the core control module at real time, the core control module sends off prompt signal or control instruction after comparing the analysis data with preset data, the core control module is connected with the treatment light source and the fluorescence exciting light source. The photodynamic treatment device can conduct real-time automatic monitoring during the photodynamic treatment on the target area, can make timely objective assessment on the curative effect, and is helpful for improving the effect of photodynamic treatment on tumour.

Description

【Technical field】 [0001] The invention relates to the technical field of medical devices, in particular to a photodynamic therapy device for tumor photodynamic diagnosis and photodynamic therapy. 【Background technique】 [0002] When the photosensitizer is irradiated by light with a shorter wavelength, it will produce fluorescence with a longer wavelength. This phenomenon is called the fluorescence effect of the photosensitizer. The method of diagnosing diseases by utilizing the fluorescence characteristics of photosensitizers is called Photodynamic Diagnosis (PDD). In photodynamic diagnosis, blue-violet light is usually chosen as the excitation light source to obtain higher fluorescence quantum yield and richer fluorescence information. [0003] When the living tissue that ingests the photosensitizer is irradiated by light of appropriate wavelength, singlet oxygen and free radicals will be generated due to the excitation of the photosensitizer, which will attack the target ...

AI Technical Summary

Problems solved by technology

[0006] In the traditional photodynamic therapy scheme, photodynamic diagnosis and photodynamic therapy are carried out separately depending on different equipment, so the guiding role of diagnosis to treatment will be weakened due to the difficulty of information docking and the error of human judgment. It is impossible to conduct real-time automatic monitoring of the photodynamic therapy process in the target area, and it is also impossible to conduct timely and objective evaluation of the treatment effect
