Abstract: A single surgical instrument capable of being used as a powered resection instrument or a conventional liposuction cannula. The instrument is elongated and may be used in either open or closed (endoscopic) lipectomy procedures, with or without visualization. The instrument comprises a stationary elongated outer tube having a side-facing window near its distal tip and a rotatable elongated inner tube situated within the outer tube and having a cutting edge juxtaposed adjacent the window of the outer tube. The method of using the device comprises the steps of utilizing it as a powered resecting instrument, in which the uniquely shaped surfaces of the inner edge and outer window cooperate to resect tissue, or as a liposuction cannula in which the inner member is stopped in alignment with the outer window.
