1. An instrument comprising:
- a handle having a handle distal end and a handle proximal end;
a piston having a piston distal end and a piston proximal end, the piston distal end and the piston proximal end disposed within an inner bore of the handle;
a spring configured to provide a force having a spring distal end and a spring proximal end, the spring disposed within the inner bore of the handle;
an inner sleeve having an inner sleeve distal end and an inner sleeve proximal end, the inner sleeve having a first stiffness;
a support sleeve having a support sleeve distal end and a support sleeve proximal end wherein the support sleeve proximal end is fixed within the piston, the support sleeve having a second stiffness wherein the second stiffness is greater than the first stiffness and wherein a portion of the support sleeve is configured to decrease a flexibility of a portion of the inner sleeve; and
a protected portion of the inner sleeve, the protected portion of the inner sleeve disposed within the piston and the support sleeve.

Abstract
A surgical instrument may have a handle, a support sleeve, and an inner sleeve. Illustratively, the support sleeve may be configured to actuate relative to the inner sleeve to protect the inner sleeve before and after a surgical procedure and to expose a portion of the inner sleeve during the surgical procedure. In one or more embodiments, an application of a force to a distal end of the support sleeve may be configured to retract the support sleeve relative to the inner sleeve. Illustratively, a reduction of a force applied to the distal end of the support sleeve may be configured to extend the support sleeve relative to the inner sleeve.
