Abstract:
1. A device comprising an electrosurgical system for morcellating tissue within a body cavity of a patient, the system comprising: an electrosurgical generator, a morcellating device, and a tissue-pulling device, the morcellating device comprising: the tissue-pulling device being locatable within the tube, and including a third connection by which the tissue-pulling device is connected to the electrosurgical generator so that the tissue-pulling device is an additional electrode, the electrosurgical generator supplying an electrosurgical cutting voltage to the electrode assembly, such that when the tissue-pulling device is moved to pull tissue against the distal end of the tube, the electrosurgical cutting voltage supplied to the bipolar electrosurgical electrode assembly and/or tissue pulling device severs the tissue to form a core of tissue within the tube, which can then be further moved in order to remove the severed tissue from the body cavity of the patient.
