Abstract

The present invention discloses a rectal cancer photodynamic therapy mini-type LED illumination source based on wireless power supply. The source comprises bullet-shaped housing, the housing is internally provided a voltage regulator module and a LED light source with the wavelength range of 630-650nm, the housing is internally provided with a LC resonance matching receiving coil and a first rectification filter circuit, the LC resonance matching receiving coil is 20*5*2mm, and the inductance value is 60[Mu]H; the mini-type LED illumination source also comprises an electric power emission unit consisting of a current generation current and a LC resonance matching sending coil; and the current generation circuit is configured to generate alternating current to allow the LC resonance matching sending coil to generate resonance. The Rectal cancer photodynamic therapy mini-type LED illumination source based on the wireless power supply can obtain electric energy at any moment so as to solve the power supply problem in the rectal suppository therapy and enhance the reliability of the rectal suppository. The contradictions of the mini-type implantable medical device power supply and the small size, and the attention of medical staff to the rectal suppository electric quantity is saved, and a condition is created for the product clinical expansion.

Description

technical field [0001] The invention belongs to the field of laser irradiation light source design in photodynamic therapy research, and relates to a miniature LED irradiation light source based on wireless power supply technology that can be implanted in the rectum. Background technique [0002] Rectal cancer (colorectal cancer, CRC) is a malignant tumor originating from the rectal mucosa. It is one of the most common malignant tumors of the digestive system. Its mortality rate is high and its incidence is increasing year by year. Early diagnosis is difficult due to atypical symptoms in the early stage. Most patients are already in the middle and late stage when clinical symptoms appear. In recent years, with the advances in molecular biology research of colorectal cancer, its treatment is not limited to traditional methods such as surgery, radiotherapy, and chemotherapy. The treatment model of rectal cancer is changing, but its 5-year survival rate is still not high . W...
