Abstract
A surgical instrument includes an outer tube configured to be gripped by a user, and a needle slidably disposed within the outer tube. The needle includes a needle lumen, a distal needle tip configured to pierce tissue, and an electrode disposed at the distal needle tip. The needle lumen opens to the distal needle tip such that the distal needle tip is configured to deliver fluid from the needle lumen to tissue. The electrode is operable to deliver RF energy to tissue for ablating the tissue. The needle is translatable relative to the outer tube between a proximal retracted position in which the distal needle tip is housed coaxially within the outer tube, and a distal extended position in which the distal needle tip is exposed from the outer tube and configured to pierce tissue.
