ADJUSTABLE STIFFENER FOR SURGICAL INSTRUMENTS

Abstract:

The present disclosure generally relates to microsurgical instruments having variable stiffness such as microsurgical instruments having variable stiffness for ophthalmic surgical procedures. In one embodiment, a surgical instrument includes a probe and a stiffener assembly. The stiffener assembly further includes a stiffener formed of a hollow tubular member substantially surrounding at least a portion of a length of the probe. Actuation of the stiffener along the length of the probe adjusts the stiffness of the probe, thus providing a user better control of the surgical instrument.
