Surgical retractor systems, illuminated cannulae, and methods of use

摘要

Abstract A surgical retractor includes a first base component having a first blade coupled thereto and a first connector arm extending therefrom; a second base component having a second blade coupled thereto and a second connector arm extending therefrom, the second base component being coupled to the first connector arm for translating motion with respect to the first base component; and a third base component having a third blade coupled thereto, the third base component being coupled to the second connector arm for translating motion with respect to the base component; the first, second, and third base components being configured to define a major plane and to define an access portal through the major plane through which surgery can be performed.
