A surgical retractor apparatus (10) having one or more independent, removabl e extension members (20) adapted to be mounted at the distal end (13) of the retractor (10), or between the blades of a spreadable retractor (10), after the retractor (10) has been positioned in the patient, such that a significa nt portion of the extension member (20) extends beyond the distal end (13) of t he retractor (10) to preclude or minimize intrusion of tissue into the access area created by the retractor (10). The extension members (20) may vary in size and shape so that the most appropriate extension member (20) can be chosen to address the intrusion problem, and the extension members (20) may be mounted at various fixed locations, using clips (33), mechanical interlockin g structures or the like. |
