Abstract

The invention discloses a nevus flammeus photodynamic precise treatment system, which comprises a three-dimensional position adjusting device. The three-dimensional position adjusting device is provided with an imaging CCD, a 45-degree 510 nm mirror and an imaging lens group along a horizontal coaxial optical path. The imaging lens group is provided with a focal length adjusting device. An infrared temperature measuring probe is arranged on the right side of the three-dimensional position adjusting device. A 510 nm LED array is arranged on the front side of the 45-degree 510 nm mirror. An optical power detecting probe and an optical power detecting lens are arranged on the rear side of the 45-degree 510 nm mirror. The optical power detecting lens is disposed between the optical power detecting probe and the 45-degree 510 nm mirror. The system determines the shape and color distribution of the nevus flammeus on the surface of the skin, accurately outputs the spot size and the spot shape, and can adjust the light output power of different parts of the spot to achieve precise treatment, can detect the optical power density in real time, can monitor the surface temperature of the focusin real time, ensures the safety of treatment, has a data upload function capable of uploading system parameters to the cloud server in real time.

Description

technical field [0001] The invention belongs to the field of medical equipment, and more specifically relates to a photodynamic precise treatment system for port wine stains. Background technique [0002] Port wine stain, also known as port wine nevus or telangiectatic nevus, is a congenital telangiectatic malformation of the papillary dermis. [0003] When photodynamic therapy is used to treat port wine stains, the photosensitizer (Fumeta) will form a peak concentration in the blood after intravenous injection, and be quickly absorbed by vascular endothelial cells, while the absorption by epidermal cells is still very small, so the distribution of the photosensitizer A significant concentration difference is formed between vascular endothelial cells and epidermal cells. At this time, laser irradiation of a specific wavelength that penetrates the superficial surface and can be selectively absorbed by vascular endothelial cells is given, so that the photosensitizer produces ...
