Abstract:
1. A method of transluminal surgery, comprising the steps of: providing an endoscopic surgery apparatus including a tubular member having a plurality of channels along its longitudinal axis, wherein at least one of the channels of said tubular member is an optical channel for the transmission of images and at least one other of the channels is an illumination channel for the transmission of light, a handle located on a proximal end of the tubular member, two or more arms pivotably connected to a distal end of the tubular member and having guiding channels passing therethrough adapted to receive endoscopic surgical tools, wherein each of the two or more arms having a guiding channel are pivotably connected to the distal end of the tubular member by a single hinge, and wherein when the arms are in a closed position an opening is defined allowing for viewing of an area adjacent to the distal end via the optical channel and illumination of the area adjacent to the distal end via the at least one illumination channel; inserting the distal end of the tubular member through a natural body orifice with the arms in a closed position; advancing the distal end of the tubular member into a body cavity using the optical channel to view the body cavity; creating an incision in the body cavity wall sized to accommodate the tubular member using at least one endoscopic surgical tool; advancing the distal end of the tubular member through the incision into the abdominal cavity; advancing the distal end of the tubular member to a desired surgical site using the optical channel to view the abdominal cavity; pivoting the arms about the hinges into an open position using a mechanism on the handle such that the guiding channels passing through the arms create a desired degree of triangulation for endoscopic surgical tools disposed in the guiding channels; performing at least one surgical task at the surgical site; and pivoting the arms about the hinges into a closed position using a mechanism on the handle.
