Abstract
A surgical ablation system features a source of ablation energy, a handle adapted to operably couple to the source of ablation energy, and an ablation probe adapted to operably couple to the handle. The handle includes a housing having a proximal end and a distal end, a hub included within the housing having a plenum defined therein, and a proximal feedline in fluid communication at a proximal end thereof with the plenum and joined at a distal end thereof to a first coupling member. The ablation probe includes a probe hypotube shaft having a proximal end and a distal end, a second coupling member disposed at a proximal end of the probe hypotube shaft adapted to operably couple with the first coupling member, a distal tip adapted to penetrate tissue. Ablation energy is deliverable by the ablation probe when the source of ablation energy is operably coupled to the handle and the handle is operably coupled to the ablation probe.
