Document Type and Number:
WIPO Patent Application WO/2021/261641
Kind Code:
A1
Abstract:
The present invention relates to a photo-dynamic therapy apparatus for a local target in cancer treatment. More specifically, an endoscope is disposed in the center of an end portion of a probe used for photo-dynamic therapy, and a plurality of optical fibers are arranged along the edge to irradiate a lesion site with a plurality of light beams. Each of the plurality of optical fibers of the probe is configured to receive light from an individual light source and individually emit light. Also, each of the individual light sources confirms a light irradiation region including a lesion site from images provided in real time from the endoscope disposed at the end portion of the probe, and only the individual light source irradiating the confirmed light irradiation region is made to emit light, thus achieving local light irradiation. Thus, the apparatus adjusts the light irradiation region to minimize unnecessary damage to normal tissue. Accordingly, the photo-dynamic therapy apparatus for a local target according to the present invention makes it possible to treat various types of cancer or tumors including cervical cancer, gynecologic cancer (endometrial cancer, ovarian cancer, etc.), breast cancer, skin cancer, brain cancer, and the like, which can be locally treated because the lesion sites thereof are small.
