<p>An improved stabilizer or retractor or other surgical tool having an elongated distal arm (20) carrying a tissue-contacting mechanism (21) at its distal end and a tensioning mechanism (27) at its proximal end for locking functional components of the tool in a desired position or configuration. The tensioning mechanism is mounted to a turret or other structure attaching the distal arm to a base (24) by means of a shorter, proximally extending flexible arm (20A). The flexible proximal arm allows the tensioning mechanism to be moved relative to the base so that it can be placed more conveniently in the operative field.</p> |
