Method and apparatus for soft tissue retraction
Abstract:
A soft tissue retractor includes a retractor body and a proximal projection extends generally perpendicular to the proximal end of the retractor body. An illumination waveguide engages a slot in the retractor blade to provide illumination to a surgical site while maintaining total internal reflection in the waveguide. An illumination input is formed into the proximal end of the illumination waveguide for conducting light from a source to the illumination waveguide. The proximal projection is configured for application of counter traction without the need for squeezing the retractor body. The proximal projection may be weighted to balance the soft tissue retractor as well as enabling the retractor to provide counter traction by itself. The configuration of the proximal projection further enables self-retraction by including a flat foot to prevent rolling and sliding of the retractor when it is providing self-retraction.
