A surgical apparatus includes a seal anchor member. The seal anchor member includes a leading end, a trailing end, and at least one longitudinal port extending between the two ends. The at least one longitudinal port is dimensioned for reception of a surgical object. One end of the at least one longitudinal port is closed by a membrane, which can be pierced through by a sharp-pointed device. The at least one longitudinal port further includes at least one lip therein. The at least one lip is configured to establish a substantially sealed relation with the surgical object entered therethrough, thereby inhibiting the loss of insufflation gas between the at least one longitudinal port and the surgical object.
