Abstract
A surgical instrument includes a base unit, a probe, a stiffener, and an actuation mechanism. The stiffener is formed of a hollow tubular member substantially surrounding at least a portion of a length of the probe. The actuation mechanism is configured to actuate the stiffener along the length of the probe and adjust the stiffness of the probe, thus providing a user better control of the surgical instrument. The actuation mechanism includes a stiffener biasing device configured to apply a first biasing force against the stiffener in the distal direction and, in some embodiments, a control member configured to lock the stiffener in a position along the length of the probe.
