Abstract
A physical retractor apparatus and method for retracting anatomy during surgery wherein the apparatus includes a handle rod, a body portion, a retractor blade and a mechanism which allows the retractor blade to be angularly adjusted, and secured, to one of any number of angular positions. The handle rod may be attached to an extension arm of a surgery support frame via a standard joint clamp. Once secured, the retractor blade may be manually positioned to the desired angular position and secured in place. The adjustment mechanism includes a notched push bar which engages a brace member of the retractor blade thereby effecting movement of the retractor blade when the push bar is moved by the user. A releasable engagement member then engages one of several notches in the push rod to inhibit any further movement of the retractor blade. Pursuant to the preferred embodiment of the present invention, the retractor blade may be precisely adjusted to its desired angular position with respect to the retracted anatomy without having to also adjust the position of the handle rod itself.
