SURGICAL LIPOSUCTION INSTRUMENT WITH RADIANT ENERGY SOURCE

摘要

A cannula for a liposuction device includes an energy source for liquefying, emulsifying or softening fatty tissue near a tip end. The energy source can provide laser energy through a fiber optic cable, or can provide energy such as RF, ultrasound or IR/UV/Vis energy from a laser diode or the like. Fat is emulsified, liquefied or softened by the energy emitted from the cannula and is removed by aspiration through a series of holes disposed in the outside wall and at the distal end of the cannula. In a power assisted embodiment, the openings in the cannula shear or cut neighboring fat tissue. The tip of the cannula can be heated to promote skin tightening.
