翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Plasma Surgical ： ウィキペディア英語版 Plasma Surgical Plasma Surgical is a privately held medical device company with headquarters in suburban Atlanta, Georgia with operations in the UK and France. The company was founded based on the work of plasma physics professor Nikolay Suslov , who developed a technology to apply plasma energy to surgically treat live tissue with minimal thermal damage. == Plasmas in surgery == Cold plasmas are extensively used in industry for critical surface cleaning and have been proposed for multiple applications in Plasma Medicine, including sterilization or decontamination processes. Thermal plasmas are characterized as being macroscopically hot and have widespread industrial use in materials cutting, and more recently broad use in surgical procedures. The origins of a thermal plasma with the ability to both cut and coagulate tissue lie in the early studies by the late John Glover and his colleagues at the University of Indiana in the mid 1970s. Glover and his team described the first plasma scalpel and compared this to the use of the steel scalpel and electrosurgery. Although effective as a surgical tool, this relatively simple two electrode handpiece device involved a relatively high gas flow and in early pre-clinical and clinical use there was evidence of argon gas in the circulation with the concomitant risk of gas embolism. No subsequent development ensued and no commercially available system arose from this early work. In the mid 1990s, Nikolay Suslov invented a multielectrode system that generated plasma with a higher power density using a very low level of current.〔Suslov N, Inventor; Plasma Surgical InvestmentsLtd., assignee. Device to stop bleeding in living human and animal tissue. United States Patent No 5,843,079, 1998.〕 This design used a low level DC current to generate a spectrally pure plasma flow in a small electrode group that facilitated the design of small diameter handpieces capable of generating a high power density of plasma flow using a very low argon flow of typically 0.2 - 0.6 l/min. This approach was developed further in 1999–2008 to create the company's flagship prodcut. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Plasma Surgical」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
