A retractor used to assist in cuff implantation, cuff removal, retracting soft tissue, and nerve repositioning comprising:
- (a) a passive grip handle that is rounded and comfortable to fit in the hands of the user;
- said handle has a lower convex surface and a lowest point (H) on said lower convex surface from a side elevational view;
- (b) a main shaft extending upwardly from said handle comprising a shape having a three degrees of freedom bend along three axial planes and two finger rests, one finger rest on an upper surface of said main shaft and the other finger rest on a lower surface of said main shaft;
- (c) an integral supporting shaft extending downwardly from said main shaft and gradually transitioning to a more flat and narrow profile along three axial planes;
- said supporting shaft has a lower surface and a lowest point (F) on said lower surface from a side elevational view;
- and
- (d) a non-cutting, nontraumatic retracting end extending gently upward from a distal end of said supporting shaft at an angle, said angle specified by a first angle (R1) and a second angle (R2);
- wherein said retractor does not have a longitudinal axis.
