surgical carbon dioxide laser knife

University of Tokyo in 1992, according to Research and Development Institute T ? Fujioka reported that the Japanese CO2 laser processing machine for the 55.8 billion yen sales, YAG laser processing machine with annual sales of 177 billion yen, a total of 73.5 billion yuan on. CO2 laser processing machine is mainly used in cutting and punching (94.8% of total number of units), welding (2.8%); and YAG laser processing machine is mainly used markers (34.5%), welding (27.7%), fine (10% ) and cutting, drilling (8.9%). Japan's production of CO2 laser manufacturers have 60, producing mainly CO2 laser processing machine manufacturer Mitsubishi Electric, Matsushita Electric, Amada and Mazak and other companies, accounting for 70% of the Japanese market around the laser processing. Another German company, and Rofin-Sinar Laser and Nippei Toyama Japanese company Marubeni joint venture; German company Trumpf laser technology and Ishikawajima-Harima Heavy Industries of Japan joint venture, which indicates that Germany's CO2 laser processing machine laser processing has entered the Japanese market. YAG laser produced in Japan Japanese Electric, Fuji TV, Toshiba 30 manufacturers. About 70-80% of the CO2 laser for cutting, about 70% of the YAG laser for the electronics industry. In addition, according to statistics, in 1995, Japan has so far set up 1,500 laser processing station. Recent years, at an annual rate of new homes increased 200-300. Japan began in Ar laser retinal laser coagulation of medical, surgical carbon dioxide laser knife, medical Nd: YAG laser endoscopy ushered in the first medical laser thermal energy generation. The net weight of this kind of laser pointer is only 100g.
With the advances in laser technology, laser therapy was born chemical efficiency, opening up the broad road of medical laser, Today, Japan are all in the medical field of laser applications. Japan's use of Nd: YAG SHG laser (532 nm) of medical lasers, the fundamental power of 60W, tone harmonic power of about 20W, through the KTP wavelength conversion has been widely used in health care. Er: YAG laser light compared with the 2.94-micron to 10.6 micron carbon dioxide laser is more susceptible to water, Ca, P, etc. are absorbed, used for cutting, removal of more water body incision of soft tissue and bone, the performance is much better than carbon dioxide laser knife .
