Manufacturing of Microsurgery Tools by Micro-electrodischarge machining

摘要

A prototype microsurgery tool consisting of outer and inner tubes and blades fabricated by micro-electrodischarge machining is manufactured. Several techniques are developed to fabricate the tiny cutting edges of the tool. A precise cutting edge of less than 1 micrometer roughness is obtained, which is equivalent to a conventional razor. The tool is proven useful in the study.
