  • Angled rotary tissue cutting instruments and inner members therefor having flexible couplings
    Patent number: 8029524
    Abstract: A flexible inner tubular member for rotation within an angled outer tubular member of a rotary tissue cutting instrument includes a distal end having a cutting element, a proximal end connectible with a powered surgical handpiece, and a flexible coupling between the distal end and the proximal end for transmitting torque to rotate the cutting element while conforming to the angled configuration of the outer member. The flexible coupling comprises inner, middle and outer spiral members, each formed of a flat strip of material, alternately wound in opposite rotational directions. The strips of material that form the inner and outer spiral members have a width intentionally and measurably different from the width of the strip of material that forms the middle spiral member.
