Multifunctional fluorescence diagnosis and photodynamic therapy endoscopic diagnosis and treatment system

Abstract

The invention relates to a multifunctional fluorescence diagnosis and photodynamic therapy endoscopic diagnosis and treatment system which is characterized by comprising a computer, a light source control device, an endoscope and an imaging device, wherein the computer is connected with the light source control device; the light source control device comprises a red-ray semiconductor laser, a blue-ray semiconductor laser and a white-ray light source; the red-ray semiconductor laser and the blue-ray semiconductor laser output laser respectively through a two-in-one fiber coupling module; the endoscope is connected with the computer through the imaging device; and the main body of the endoscope is connected with the light source control device. The invention has the advantages that the system integrates the three functions of ordinary celiac diagnosis, a tumor fluorescence diagnosis image system and tumor photodynamic therapy into a whole; the system not only can be used for ordinary diagnosis by adopting a white-ray light source, but also can be used for carrying out fluorescence diagnosis by adopting a blue-ray light source, and also can be used for carrying out photodynamic therapy by adopting a red-ray light source; and the three light sources can be simply and conveniently switched.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a multifunctional fluorescence diagnosis and photodynamic therapy endoscopic diagnosis and treatment system. Background technique [0002] Traditional endoscopes can enter human tissues for visual inspection in vivo, which improves the diagnosis level of tumor tissues in vivo. However, due to the limitation of resolution and other technical indicators, it is still impossible to identify small lesions that cannot be recognized by naked eyes. At present, endoscopes with fluorescence diagnostic functions have appeared in the world. Laser fluorescence diagnosis uses laser light to excite the affinity fluorescent agent in tumor cells, which produces a fluorescence effect different from that of surrounding normal tissues, and can clearly show the shape of tumor tissue. And location, so that doctors can easily distinguish and diagnose tiny tumor tissues invisible to the naked eye. There have been l...
