▎ 摘  要

NOVELTY - The tip has a main portion which is provided with a shaft with an insertion end (104). The main portion receives ablation unit from an ablation source. The main portion ablates targeted tissue. The main portion comprises shaft which includes a coaxial antenna, center of ablation located within coaxial antenna near insertion end. A heat transfer layer (130) surrounds coaxial antenna, and spaced from insertion end such that center of ablation is between heat transfer layer and insertion end. A thermal reservoir (134a) partially surrounds heat transfer layer. An ablation zone surrounds center of ablation when ablation unit is provided to ablation probe tip. The heat transfer layer provides ablation zone temperature control. The thermal reservoir is a combination thermal reservoir made from a combination of two materials selected from the group consisting of air, water, ice, aluminum, silver, copper, diamond, boron nitride, graphene, graphene nanotubes, and pyrolytic graphite. USE - Ablation probe tip such as microwave ablation probe tip, radiofrequency ablation probe tip and micro-ablation ablation probe tip (claimed), used in medical industry for removal of problematic such as damaged, diseased, or otherwise undesired tissue, for ablating targeted tissue. ADVANTAGE - The tip enables guided soft tissue ablation procedures that are more precise and predictable. The tip removes or destroys the targeted tissue with less damage to surrounding tissue or structure compared to more invasive conventional surgical methods while restoring normal function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for cooling ablation probe tip. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective side view of the ablation probe tip with fluid thermal reservoir.
