Abstract

An improved lipectomy device, or cannula, is disclosed having inner and outer tubes. The outer tube has an elongated aspiration aperture, and the inner tube has a spiral slot. A mechanism inside the handle of the device causes the inner tube to rotate, creating a traveling hole effect along the aspiration aperture. This obviates the necessity of the surgeon repeatedly pushing the cannula in and out.
