Multipurpose medical light source system

Abstract

The invention discloses a multipurpose medical light source system. The medical light source system comprises a core control device, an optical convergence component, a combiner, a multiple wavelength LED light source, an execution mechanism and a selective light source, wherein the multiple wavelength LED light source, the execution mechanism and the selective light source are controlled by the core control device, and the multiple wavelength LED light source comprises a fixed plate and at least one LED light-emitting substrate fixed on the fixed plate; the execution mechanism drives the fixed plate to move under the control of the core control device so that the central point of the emitting light of the LED light-emitting substrate moves to an incident light axial line of the optical convergence component; light beams of the LED light-emitting substrate are aligned and output to the input end of the combiner through the shaping and the focusing of the optical convergence component, and the selective light source is connected with the other end of the combiner. The light emitted by the LED light-emitting substrate and the selective light source can be output in time share through the combiner, or a combined beam formed by the light emitted by the LED light-emitting substrate and the selective light source can be output to really realize the multipurpose of one machine.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a multipurpose LED light source system. Background technique [0002] Photodynamics is a treatment and diagnosis method that combines light and photosensitizer drugs, and its application range in the treatment and diagnosis of tumors and non-tumor diseases in the human cavity or on the surface of the body is becoming wider and wider. A large number of experimental studies and clinical applications have proved that photodynamic therapy has broad application prospects in treatment and diagnosis. [0003] Photodynamic therapy (PDT) is a new method to treat tumors by exciting intracellular photosensitizers in target cells under aerobic conditions. The principle is that photosensitizers produce reactive oxygen species (reactive oxygen species, ROS) to directly damage tumor cells, and damage microvessels, resulting in reduced blood perfusion of cancer tissues, which in turn leads to a...

Problems solved by technology

The current medical light sources are all independent light sources. Therefore, if the above-mentioned treatment light sources, excitation light sources and illumination light sources need to be used comprehensively during a treatment process, the doctor needs to connect the required light sources to appropriate interfaces during different treatment periods. , which is not only inconvenient for doctors to operate, but also cannot strictly guarantee the continuity of treatment, thus prolonging the treatment time and possibly affecting the treatment effect
