Abstract
A surgical instrument includes a deflectable cutting element extending from the distal end of the instrument. The deflection of the cutting element is controllable based on a user operating a moveable member of the instrument. The deflectable cutting element is normally disposed within a circumferential region defined by the distal end of the instrument. The moveable member can be moved in relation to the instrument to deflect the deflectable cutting element, such that the cutting element is at least partially outside of the circumferential region. The extent that the cutting element is outside of the circumferential region is a function of the position to which the moveable member is moved in relation to the instrument. The instrument further includes direct imaging of the distal end, such that the deflection of the cutting element for selective removal of bone tissue at the distal end of the instrument can be controlled in real-time.
