Abstract:
1. A method of removing a portion of a lung from other portions of the lung, the method comprising: providing a surgical instrument with a source of work energy that is coupled to a dissecting member extending at a forward portion of the instrument, the forward portion of the instrument comprising a plurality of grooves having groove widths; activating the source to induce a cyclical motion of the dissecting member; contacting the forward portion of the instrument to a lung tissue and to a lung structure so that the dissecting member contacts the lung structure, the lung structure comprising an artery, a vein, or an airway having an outer diameter; and selectively dissecting lung tissue away from the lung structure with the cyclical motion of the dissecting member while the contact between the lung structure and the forward portion of the instrument inhibits damage to the lung structure, the groove widths being less than the outer diameter of the artery, the vein, or the airway so as to inhibit damage by the cyclical motion of the dissecting member to the artery, the vein, or the airway.
