<P>PROBLEM TO BE SOLVED: To provide a hemostatic electrosurgical instrument which can efficiently provide hemostasis in tissue of varying impedances, thickness and vascularity. <P>SOLUTION: An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedances, thicknesses and vascularity especially in the performance of endoscopic procedures. The instrument compresses the tissue between the first pole 52 of a bipolar energy source located on one interfacing surface 33, and a second interfacing surface 35. A second pole 18 is located on one of the two interfacing surfaces 33, 35. In a preferred embodiment, the second pole 18 is located on the same interfacing surface 52 as the first pole and an insulator 55 electrically isolates the two poles 52, 18. The device is used along with a cutting instrument wherein a hemostatic line is formed along a cut line using RF energy. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
