An endoscopic surgical instrument includes an insertion section which is inserted into a body cavity, and a surgical section which is disposed on a tip of the insertion section and treats an object. The surgical section includes a body section, and a first electrode, a second electrode, and a third electrode which are disposed on the body section. The surgical section coagulates and cuts the object by using a combination of not less than two of the first electrode, the second electrode, and the third electrode.

Endoscopic surgical instrument

A ring dissector/harvester device for dissecting and harvesting a vessel has a capture tool that is co-axially positioned around the vessel to at least temporarily hold the vessel. A sealing tool is coaxially positioned within the capture tool and is axially movable with respect to the capture tool. The sealing tool and the capture tool are engaged to cauterize a branch from the vessel and to seal the cauterized branch and vessel.

Ring vessel dissector/harvester device

A cutter for a blood vessel tissue harvesting instrument is disposed at the distal end of an insertion member. A cutter body projecting from the distal end of the insertion member includes a slit that extends from the distal end toward a base edge. High-frequency electrodes are disposed along the sides of the slit. A feeding mechanism has rotating surfaces which are rotated as a result of being pressed by the tissue, and which feed the tissue toward the base edge of the slit. The rotating surfaces are provided by two rotary members disposed opposite each other along the two side edges of the slit, respectively, so that the first and second rotating surfaces move in a direction from the opening of the slit toward the base edge of the slit.

Body tissue incision apparatus

A blunt dissector for separating a blood vessel from surrounding tissues in a body comprises a longitudinal rod having a proximal end, a distal end, and an internal passage for conducting insufflation gas between the proximal and distal ends. An interior sleeve is mounted within the longitudinal rod for receiving an endoscope at the proximal end. A transparent tip is mounted to the distal end of the longitudinal rod. A handle is mounted to the proximal end of the longitudinal rod. The longitudinal rod has an outer surface along substantially all of the longitudinal rod between the proximal and distal ends consisting essentially of a fluoropolymer.
