Abstract:
1. Surgical apparatus thr liposuction comprising: a microwave energy source arranged to Output a controllable power level of microwave radiation; a probe for inserting to a treatment region in biological tissue, the probe including: a suction pump connected to the conduit; a detector arranged to detect forward microwave power delivered to the probe; and a controller for adjusting the controllable power level of microwave radiation, wherein the detector is arranged to detect microwave power reflected back from the treatment region; the controller is arranged to select an energy delivery profile from a plurality of predetermined energy delivery profiles based on changes in the detected reflected microwave power based on the detected forward and reflected microwave power to deliver microwave energy according to a predetermined energy delivery profile; and the apparatus further comprises: wherein the plurality of predetermined energy delivery profiles include energy delivery profiles in which the frequency of the microwave radiation and the controllable power level are selected such that the emitted microwave radiation field automatically adopts a first configuration when emitted into fat and a second configuration when emitted into blood, the microwave energy delivered by first configuration being for liquefying the fat and the microwave energy delivered by the second configuration being for coagulating the blood.
