Abstract
A laparoscopic nephrectomy device is disclosed. The device has an upper jaw and a lower jaw designed to clamp a portion of an organ, such as a kidney, so as to cut off blood flow locally to a portion of that organ. The upper jaw includes a mid-jaw piece and a top jaw piece, with each piece separately articulated. The mid-jaw piece is pivotably connected to the lower jaw. A top jaw piece is pivotably connected to the mid-jaw piece. The mid-jaw and top jaw pieces include a mechanism to fix the angular orientation of the mid-jaw and top jaw pieces with respect to one another, including a retractable slide piece that is carried by the mid-jaw piece and received in a slot in the top jaw piece. The jaws have insulated troughs that carry electrode structure for applying coagulative therapies.
