Title: Expanding seal anchor for single incision surgery

Abstract: The present disclosure relates to a surgical anchoring apparatus for use during a minimally invasive surgical procedure. The surgical anchoring apparatus includes a body member and a dilator element at least partially positionable therein. The body member includes a grip segment adapted for manual engagement by a user and an expandable section having a plurality of expandable segments and a plurality of cam surfaces. The grip segment resiliently transitions between a first or normal state and a second state in which the grip segment is at least partially inverted. The expandable section's cam surfaces are configured to engage a distal end of the dilator element upon its insertion such that the expandable section may transition from an initial condition to an expanded condition in which the body member is secured or anchored within an incision in tissue.
