Title
(EN) NEEDLE INSTRUMENT FOR POSTERIOR NASAL NEURECTOMY ABLATION
(FR) INSTRUMENT À AIGUILLE POUR ABLATION DE NEURECTOMIE NASALE POSTÉRIEURE
Abstract
(EN)
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.
(FR)
L'invention concerne un instrument chirurgical comprenant un tube externe configuré pour être saisi par un utilisateur, et une aiguille disposée de façon coulissante à l'intérieur du tube externe. L'aiguille comprend une lumière d'aiguille, une pointe d'aiguille distale configurée pour percer un tissu, et une électrode disposée au niveau de la pointe d'aiguille distale. La lumière d'aiguille s'ouvre sur la pointe d'aiguille distale de telle sorte que la pointe d'aiguille distale est configurée pour distribuer un fluide depuis la lumière d'aiguille vers un tissu. L'électrode peut fonctionner pour délivrer de l'énergie RF au tissu pour l'ablation du tissu. L'aiguille peut être déplacée par rapport au tube externe entre une position rétractée proximale dans laquelle la pointe d'aiguille distale est logée coaxialement à l'intérieur du tube externe, et une position étendue distale dans laquelle la pointe d'aiguille distale est exposée à partir du tube externe et configurée pour percer un tissu.
