CA 2748008

An electrosurgical cutting device and method thereof for incising tissue are disclosed. The electrosurgical cutting device includes an asymmetrical cutting element that is affixed to a distal end of a torque cable. The cutting element is disposed within an end cap and is axially movable between a retracted position and an extended position. Rotation of the torque cable during a procedure allows the cutting element to rotationally align with and hook the target tissue onto the cutting element. An elongate member of the cutting element selectively lifts the target tissue away from surrounding tissue and structures. Having lifted the tissue away the surrounding tissue and structures, incision can occur.

L'invention concerne un dispositif coupant pour électro-chirurgie et son procédé pour inciser un tissu. Ledit dispositif comprend un élément coupant asymétrique fixé à une extrémité distale d'un câble de couple. L'élément coupant, qui est disposé à l'intérieur d'un capuchon d'extrémité, est mobile axialement entre une position rétractée et une position étendue. La rotation du câble de couple pendant une intervention chirurgicale permet que l'élément coupant s'aligne en rotation avec le tissu cible et l'accroche sur l'élément coupant. Un élément allongé de l'élément coupant soulève de façon sélective le tissu cible pour l'éloigner du tissu et des structures environnants. Une fois le tissu soulevé et éloigné du tissu et des structures environnants, l'incision peut être pratiquée.
