Abstract: Disclosed is a device for resecting an organ in a cavity of a living body. The device includes a guide with a tube and a tube, both cylindrical, the tube being mounted in the first tube; an electrical conductor surrounded by an electrically insulating sheath, the tube being a cylinder of revolution with an inner radius of value R1, the tube including a part which is a cylinder of revolution with an outer radius of value R2<R1 and with an angle at the center of a value Ac, and a part which is not a cylinder of revolution and has an angle at the center of value “360°?Ac”; the insulated conductor contacts the part of the tube, between the outer and inner walls of this tube; and a unit for keeping this insulated conductor in contact with the part of the tube.

Abstract: Disclosed are laparoscopy forceps, including a yoke with a hole, two jaws; a unit for mounting the jaws to pivot relative to the yoke about an axis; a control rod mounted to move in translation in the hole; a pantograph connecting the rod and two jaws using links mounted to pivot on the rod about an axis, two cams secured to the jaws, a mount for each link to pivot relative to a respective one of the two cams about axes, the four pivot axes being parallel, the outside diameter of the yoke being 2D, the width of the links being 2E, the distance between the axes when the two grip faces of the jaws are in contact being 2C, the angle under such circumstances between the axes being 2A, and the values D, E, C, and A being substantially associated by the following equation: D=C+E/cosA.

Abstract: The present invention relates to laparoscopy forceps.
