ABSTRACT:
A retractor for use in invasive surgery. The retractor includes a superelastic or shape memory alloy shaft having proximal and distal ends. A handle is attached to the proximal end, while the distal end has a shape trained into it adapted to grasp animal tissue. The distal end is designed to release at an amount of force lower than that which would cause tissue damage. Thus, should excessive force inadvertently be applied, the retractor will safely release before tissue damage occurs. A further advantage of the retractor is its ability to safely maintain retraction from a more remote location.
