Getting an edge on super-robust surgical blades

Hutchinson Technology has counted super-precise photochemical etching as a core technology in its evolution over the decades. The company is now preparing to use the same technology to produce thousands of tiny stainless-steel surgical blades less than an inch in length. An undisclosed major medical device company recently received FDA approval for a surgical device that uses Hutchinson’s blades, and the company is working on securing more major customers. Hutchinson would not divulge details of the process, but the blades are created not through grinding but through a modified version of the photochemical etching process. The process can result in serrated blades with only about 25 microns between each tooth. Source :  http://www.twi-global.com/news-events/industry-updates/medical-industry/
