Abstract
A tissue retractor device within the scope of the present invention generally includes a frame, an actuating mechanism, and a plurality of blades. The actuating mechanism generally includes at least one cam that encourages automatic toe-out of the blades. The tissue retractor eliminates the need for bulky secondary blade mechanisms to prevent undesired blade deformation at the surgical site. The toe-out motion occurs simultaneously along with the opening of the blades. The present invention further provides for depth adjustment of the blades by means of an adjustable screw assembly.
