ABSTRACT:
An internal retraction system for use in minimally-invasive surgical procedures includes, among other features, an elongated applicator that has proximal and distal ends. The distal end of the applicator includes a grasper and the proximal end includes a mechanism or actuator for moving the grasper from an open position to a closed position. A plurality of anchor clips are slidably mounted on the elongated applicator and are initially in a stored position. Each clip includes spring biased upper and lower jaws for grasping tissue. The internal retraction system also includes a structure associated with the applicator for deploying the anchor clips from the stored position to a deployed position at a desired location. Moreover, the internal retraction system includes a mechanism associated with the applicator for removing the anchor clips from the deployed position and returning the clips to the stored position.
