The invention relates to a topical targeting photodynamic therapy device for the treatment of cancer. More specifically, an endoscope is disposed at the center of the end of a probe for photodynamic therapy, and a plurality of optical fibers are disposed along the edge to irradiate a lesion site with a plurality of light beams, the plurality of optical fibers of the probe receiving light from independent light sources to independently irradiate the light beams. The present invention is a device for minimizing unnecessary damage to normal tissue by adjusting a light irradiation region, in which each of the independent light sources specifies a light irradiation region including a lesion site in an image provided in real time by an endoscope disposed at an end of a probe, and only the independent light source that irradiates the specified light irradiation region emits light. Therefore, local light irradiation and the like are realized. The photodynamic therapy device for local targeting according to the present invention can treat various types of cancers or tumors, which have small diseased regions such as cervical cancer, female cancers (endometrial cancer, ovarian cancer, breast cancer), skin cancer, brain cancer, and the like and can be locally treated.
Description
technical field [0001] The present invention relates to a photodynamic therapy device for local targeting and a control method thereof for treating cancer. In more detail, an endoscope is arranged at the center of the end of the probe used for photodynamic therapy, and a plurality of optical fibers are arranged along the edge to irradiate a plurality of lights to the lesion. The light source receives light to perform light irradiation independently. Furthermore, it relates to a device for minimizing unnecessary normal tissue damage by adjusting a light irradiation area and a control method thereof: each independent light source is determined to include In the light irradiation area of the lesion, only the independent light source that irradiates the determined light irradiation area emits light, thereby realizing partial light irradiation and the like. Therefore, the photodynamic therapy device for local targeting and its control method of the present invention can achieve...
