Zusammenfassung:A rotary tissue-cutting instrument forming a laryngeal blade (3) includes an outer tubular member (14) having a hub (4), a proximal portion (150) having a longitudinal axis and extending distally from said hub to a proximal bend (151) curving in a first direction. An intermediate portion (152) extends distally at an angle to the longitudinal axis of said proximal portion (150) in a first plane. The intermediate section extends from the proximal bend (151) to a distal bend (153) curving in a second direction, and a distal portion (154) extends distally from the distal bend (153) in a second plane. The distal portion (154) extends to a distal end having an opening (16) therein. An inner member (15) is rotatably disposed in the outer tubular member (14) and has a proximal end for mounting to a powered handpiece and a distal cutting tip (17) disposed adjacent the opening (16), the inner member being flexible adjacent said distal and proximal bends.
