Retractor extensions and methods of use

摘要

A retractor extension is provided comprising a body having a distal end and a proximal end extending longitudinally from the distal end, the distal end of the body comprising a first set of engagement members comprising a first projection configured for attaching the body to a first end surface of the retractor, the proximal end of the body comprising a second set of engagement members comprising a second projection configured for attaching the body to a second end surface of the retractor. In some embodiments, the retractor extension holds tissue away from the surgical incision to enhance the surgeon's field of vision. Methods of attaching the retractor extension to the retractor are also described.
