ABSTRACT:
A push-type hand-held surgical retractor definable in terms of an xyz Cartesian coordinate system, includes a substantially flat retaining element having a primary surface in a yz plane and a secondary surface, substantially normal thereto, in an xy plane. The retractor also includes a curved elongated rigid shaft having first and second ends and having a gradual x-axis curve in both the xy plane and an accentuated y-axis curve in the xy and yz planes, the curved shaft having, at the first end, an arched portion having the y-axis curve, in which the first end integrally depends from an upper side of the secondary surface of the retaining element. The retractor further includes an ellipsoidal loop-like gripping element integrally depending from the second end of the curved elongate shaft.
