RF MICRO-NEEDLE FOR GLAUCOMA SURGERY

摘要

A bipolar diathermal micro-needle for creating a micro-canal, said needle comprising a first (11) and a second electrical conductor (10). The first (11) and a second conductor (10) are electrically separated and at least the first conductor (11) comprises a cutting part (4). The micro-needle comprises an orientation mark (7), and the cutting part (4) comprises a peripheral surface (8) and terminates in an end surface (9). The second conductor 10 surrounds the first conductor 11, and an electrically insulating material (12) separates the two conductors. The second conductor (10) terminates in an annular end surface 13, which may have a rounded part (14). The orientation mark may have a visible angle (15).
