A surgical port includes an end face with a channel extending through the end face. The channel has a cross section shaped to receive a surgical instrument cannula. A lateral wall extends around a perimeter of the end face. The lateral wall and end face enclose an open volume. A rim extends radially inward from the lateral wall and projects into the open volume. An apron portion extends radially outward from the lateral wall and in a direction axially away from the end face. Surgical systems may include surgical ports. Methods relate to using surgical ports.
