Abstract
A surgical access device includes a proximal end portion configured to support a seal assembly having an insufflation port. The device includes a cannula tube extending distally from the proximal end portion and having an inner surface that defines a lumen extending longitudinally through the cannula tube. The cannula tube is configured to be inserted distally through a body cavity wall of a patient, and the lumen is configured to guide a surgical instrument shaft distally through the cannula tube for accessing a body cavity of the patient. The device includes a channel formed in the inner surface of the cannula tube. The channel extends longitudinally between a proximal end of the lumen and a distal end of the lumen, and the channel is configured to direct a gas therethrough to or from the insufflation port of the seal assembly while a surgical instrument shaft is disposed within the lumen.
