Description

Green laser intravascular irradiation treatment instrument

Technical field

The present invention relates to a medical instrument for introducing a laser into a human body to treat a disease, and particularly to a green laser mound tube irradiation treatment instrument for irradiating blood with a green laser to treat certain diseases that only respond to green light. Background technique

Low-energy laser intravascular irradiation has been used to treat a variety of difficult conditions. Clinically, significant results have been achieved. However, the existing laser treatment instruments generally use near-infrared light for treatment. Therefore, for some diseases that only respond to green light, It seems helpless, and its scope of application and treatment targets are limited. The present invention is a Chinese patent application 93114809.X filed by the applicant on November 19, 1993, with the invention name "Visible Semiconductor Laser Intravascular Irradiation Therapy" and the Chinese application filed by the applicant on October 1, 1994 Patent application 94116657. 0, the invention name is based on "Dynamic Monitoring Semiconductor Laser Intravascular Irradiation Therapy Apparatus", the above two Chinese patent applications can already be cited. The previous patent application discloses a laser intravascular irradiation treatment instrument, which uses a semiconductor generator capable of generating near-infrared light ^ as a laser source, and introduces an optical needle through an optical fiber coupling · and an optical fiber ^ laser to directly irradiate blood with a laser to achieve treatment The purpose of the disease; the latter patent application discloses a laser intravascular irradiation treatment instrument capable of dynamically monitoring the output of laser power on a fiber optic needle, which also uses a semiconductor laser ^ as a laser source, including a DC power supply and is arranged in the housing of the host computer. Timing controller, power test display, power conditioner, alarm, various function switches, and treatment head connected with laser power output socket by wire. The purpose of the present invention is to provide a laser intravascular irradiation therapy capable of generating green light to meet the needs of demonstration applications. An object of the present invention is to provide a laser intravascular irradiation treatment instrument capable of generating green light on the basis of the foregoing prior art, so as to meet the needs of practical applications. In order to achieve the above-mentioned object of the present invention, the laser generation of the present invention is sequentially assembled in a laser generator chamber by a semiconductor laser tube and a pump, a frequency doubling crystal, a focusing lens, and a correction lens in order of light path transmission. Therefore, the semiconductor laser tube generates infrared light with a wavelength of 808 nm, which is converted into green light with a wavelength of 532 nm by pumping and frequency doubling, and is then coupled into an optical fiber through a fiber coupler, and then output by a fiber pin. Brief Description of the Drawings FIG. 1 is a schematic diagram of a semiconductor laser intravascular irradiation treatment apparatus in the prior art. FIG. 2 is a schematic diagram of the optical fiber needle fitted on the laser generator and the optical fiber output end of the present invention. The best technical solution for implementing the present invention The green laser intravascular irradiation treatment instrument of the present invention is composed of a driving power source, a host and a treatment head. As shown in FIG. 1, the key component different from the prior art is that it serves as a laser source. The semiconductor laser (4) uses an ordinary infrared light semiconductor laser tube with a wavelength of 808 nm, and a pump and a frequency doubling crystal (5) are arranged at the front end. In this way, the 808 nm laser emitted by the ordinary infrared light semiconductor laser ^ is pumped. , The frequency doubler can be converted into a green laser at 532nm, and the green laser is then focused and corrected by the focusing lens (6) and the correction lens (7) set at the front of the optical path, and can be efficiently collected into the laser generator ( 4) The optical fiber coupling on the output terminal (8) is transmitted through the optical fiber to the optical fiber pin (10) in the quick-change connector (9) fitted on the optical fiber output terminal. Industrial Applicability This semiconductor green laser intravascular irradiation treatment instrument has a compact, compact, and lightweight structure, and its parts are highly versatile. It can be injected into the blood vessels of the human body with the frequency-doubling green laser emitted by it, and it can be irradiated with blood. Some special germs and viruses in the blood have obvious therapeutic effects on the treatment of certain special diseases. At the same time, due to the different absorption of green laser by various cells in the human body fluid, the activity of super tritide dismutase is enhanced. Causes significant changes in cell membrane metabolism, thereby improving the body's immune function and achieving the purpose of enhancing physical fitness.
