Embodiments of the present invention address deficiencies of the art in respect to facet joint ablation needles and provide a novel and non-obvious ablation cannula kit with an insert. The kit includes a trocar and a hollow shaft defining a longitudinal lumen. The shaft has a proximal segment and a distal segment, such that the distal segment includes a distal tip substantially aligned with the shaft to permit passage of the trocar within the hollow shaft. The distal tip also is configured with a tissue-gripping surface in as much as a plane of the tissue-gripping surface is substantially perpendicular to a longitudinal axis of the shaft. The shaft also includes an auxiliary port extending from an exterior surface of the hollow shaft, the auxiliary port defining a hollow passageway into the hollow shaft.
