Laser Medical: The application of laser in medicine is divided into two categories: laser diagnosis and laser treatment, the former uses laser as the information carrier, and the latter uses laser pointer as the energy carrier. Over the years, laser technology has become an effective means of clinical treatment and a key technology for the development of medical diagnosis. It solves many problems in medicine and contributes to the development of medicine. At present, it has maintained a sustained and strong development momentum in many aspects such as basic research, new technology development and new equipment research and production.
The current outstanding application research of laser medicine is mainly manifested in the following aspects: photodynamic therapy for cancer; laser treatment of cardiovascular disease; excimer laser keratoplasty; laser treatment of benign prostatic hyperplasia; laser cosmetology; laser fiber endoscopic surgery; laser Laparoscopic surgery; Laser thoracoscopic surgery; Laser arthroscopic surgery; Laser lithotripsy; Laser surgery; Laser application in anastomosis; Laser application in oral, maxillofacial surgery and dentistry; Weak laser therapy, etc.
The recent research focuses of laser medicine include: (1) Studying the relationship between laser and biological tissue, especially the relationship between laser and biological tissue that has been used in many effective therapies; studying different green laser pointer parameters (including wavelength , Power density, energy density and operation mode, etc.) the relationship between different biological tissues, human organ tissues and diseased tissues to obtain system data;
(2) Study the cell biological effects and mechanism of weak laser, including: the relationship between weak laser and cell biology phenomena (gene regulation and apoptosis), the molecular biological mechanism of weak laser analgesia, and the relationship between weak laser and cells The relationship and mechanism of immunity (antibacterial, antitoxin, antiviral, etc.); (3) In-depth research on the mechanism of photodynamic therapy, laser interventional therapy, laser cardiovascular angioplasty and myocardial revascularization, and actively explore other new lasers medical technology.
(4) Conduct developmental research on important and novel photonic devices and instrument settings in medical photonics technology, such as: development of medical semiconductor laser systems, excimer laser equipment for corneal shaping and angioplasty, laser cosmetic (skin replacement, wrinkle removal, Hair transplantation) equipment or other new laser equipment, develop new working band medical laser systems and develop Ho: YAG and Er: YAG laser scalpels.
Ultra-fast ultra-strong laser: The ultra-fast ultra-strong red laser pointer is mainly based on the research and application of femtosecond laser. As a unique scientific research tool and means, the main application of femtosecond laser can be summarized in three aspects. That is the application of femtosecond laser in the ultra-fast field, the application in the ultra-strong field and the application in ultra-fine processing.
