Expandable surgical access port

An expandable surgical access port comprising:

• an activation assembly defining an activation assembly opening surrounding a longitudinal axis;
• activation arms arranged around the longitudinal axis, wherein each activation arm comprises:
• an inner arm surface facing towards the longitudinal axis and extending from a proximal arm end to a distal arm end, and
• an outer arm surface facing away from the longitudinal axis and extending from the proximal arm end to the distal arm end, wherein a distal portion of the outer arm surface located at the distal arm end comprises a first inward bend towards the longitudinal axis;
• wherein the respective proximal arm end of each activation arm is connected to the activation assembly to move between a respective first arm position in which each respective distal arm end is spaced a respective first distance from the longitudinal axis, and a respective second arm position in which each respective distal arm end is spaced a respective second distance from the longitudinal axis, wherein each respective second distance is greater in magnitude than each respective first distance;
• and
• a membrane interconnecting the activation arms to form a passage extending along the longitudinal axis, the membrane extending from a proximal membrane end to a distal membrane end, with the distal membrane end being proximate to the distal arm ends, wherein the membrane comprises a flexible material that is expandable to permit the activation arms to move from the respective first positions to the respective second positions.
