Abstract
Abstract A laser-powered surgical device with a vibrating crystalline tip for directly engaging the tissue to be treated. The device comprises a hollow handle, a laser energy transmitting conduit received in the handle and having first and second ends extending out of the handle, the first end engaging the tissue to be treated and the second end coupled to a laser energy generator, and a vibration assembly for vibrating the conduit's first end relative to the handle. The vibration assembly is driven mechanically or ultrasonically. The conduit's first end comprises the crystalline tip which is formed of sapphire, glass, quartz or ruby.
