Patent ID: 8808320

Claim:
A device, comprising: a rotatable shaft having a proximal end, a distal end and a distal opening about the distal end; an extension mechanism having a distal end, the extension mechanism configured to extend and retract in the distal opening of the rotatable shaft; a support mechanism having a proximal attachment to the rotatable shaft, the proximal attachment of the support mechanism having a first attachment and a second attachment, the support mechanism configured to extend from the first attachment to the second attachment; a cutting mechanism coupled to the extension mechanism and the support mechanism; and a control at the proximal end of the rotatable shaft, wherein the control is configured to manipulate the extension mechanism, wherein the support mechanism comprises a distal attachment to at least one of the extension mechanism and the cutting mechanism and wherein the support mechanism comprises a generally fixed length between its proximal attachment and distal attachment, such that the distal end of the extension mechanism deflects as the extension mechanism extends in the distal opening of the rotatable shaft.
