INSTRUMENT FOR ENDOSCOPIC POSTERIOR NASAL NERVE ABLATION

摘要

A surgical instrument includes an elongate shaft having a proximal shaft portion and a malleable distal shaft portion. The elongate shaft is configured to be secured to a supporting surgical instrument. An ablation head is coupled to the malleable distal shaft portion and includes at least one electrode operable to deliver RF energy to tissue for ablating the tissue. The ablation head is sized to fit within the nasal cavity of a patient with a distal end of the supporting surgical instrument. The proximal shaft portion is configured to operatively couple with an RF energy source operable to energize the at least one electrode with RF energy. The malleable distal shaft portion is configured to bend relative to a longitudinal shaft axis defined by the proximal shaft portion for selectively orienting the ablation head relative to the longitudinal shaft axis.
