Optical power therapentic equipment with fluorescence diagnostic function and operation method

Abstract

A photodynamic therapy device with the function of the fluorescence diagnosis comprises a host and an operating head which is connected with the host. The interior of the host comprises a core control module which controls the operating head. The interior of the operating head aggregates LED array treatment light source, LED array fluorescence excitation light source and an image acquisition module. The host is set into the treatment mode or the diagnosis mode through controlling the open and close of the LED array fluorescence excitation light source and the LED array treatment light source. The host analyzes a fluorescence image which is collected by the image collecting module and issues a cue signal or a control command after the comparison of the analytic data and the presetting data. The photodynamic therapy device has the diagnosis module and the treatment module which can realize the site confirmation of the light scope before the treatment and the individual design of the light dose, the real-time detection of the response in the treatment and the automatic adjustment, the follow-up assessment of the lethal effect and early detection of the residual tumor after the treatment. The photodynamic therapy device also provides an operation method of the photodynamic device with the function of the fluorescent diagnosis.

Description

【Technical field】 [0001] The invention relates to the technical field of optoelectronic medical devices, in particular to a photodynamic therapy device with fluorescence diagnosis function for tumor photodynamic diagnosis and photodynamic therapy and an operating method thereof. 【Background technique】 [0002] In the medical field, when the living tissue that has absorbed the photosensitizer is irradiated with light of the appropriate wavelength, the photosensitizer will be excited to generate singlet oxygen and free radicals to attack the target tissue. This phenomenon is called the photodynamic effect. The method of using photodynamic effect to treat diseases is called photodynamic therapy (Photodynamic Therapy, PDT). After the photosensitizer is injected into the body of a tumor patient, it will form a high concentration in the tumor tissue and maintain it for a long time. Therefore, choosing the right time to irradiate the tumor with therapeutic light will cause strong p...
