摘要：
A surgical instrument configured to deliver electrical energy to tissue of a patient includes a handle, a first conductor, and a second conductor. The surgical instrument further includes a first electrode with a first distal portion, a second electrode with a second distal portion, and a third electrode with a third distal portion, wherein each distal portion is configured to contact the tissue. The second distal portion surrounds the first distal portion and the third distal portion surrounds the second distal portion. A first gap is defined between the first distal portion and the second distal portion. A second gap is defined between the second distal portion and the third distal portion. The first electrode includes a sharp end configured to penetrate the tissue and the second distal portion includes a plurality of projections extending toward third distal portion.
