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.

Instrument chirurgical unique capable de servir alternativement d'instrument de résection à moteur ou de canule de liposuccion classique. L'instrument est allongé et peut servir aux interventions de lipectomie ouverte ou fermée (endoscopique), avec ou sans visualisation. Il comprend un tube externe fixe allongé muni d'une fenêtre latérale près de son extrémité distale, et un tube interne rotatif allongé situé à l'intérieur du tube externe et équipé d'une lame juxtaposée à proximité de la fenêtre du tube externe. On utilise l'instrument soit en mode de résection motorisé (les surfaces profilées uniques de la lame interne et la fenêtre externe fonctionnent alors ensemble pour retrancher le tissu), soit comme une canule de liposuccion (la section interne est alors stabilisée en face de la fenêtre externe).
