A hand access port device of the present invention for use in minimally invasive surgery and in particular hand assisted laparoscopic surgery is provided. Reliable and atraumatic anchoring of the device to the patient's abdominal wall in such a surgery is desired and solved by the hand access device of the present invention. For example, the proximal end of the device (10) is sealed by the outer sleeve (11) being inflated by gas and the distal end is sealed by the walls of the inner sleeve (12) being collapsed by gas pressure within a patient's body cavity acting on the walls of the inner sleeve (12). The device (10) is fitted with an internal ring (15) attached with an apron (16) to the inner sleeve (12). The internal ring (15) anchors the device below the abdominal wall of the patient and the apron (16) acts as a wound protector around the site of the incision in the patient's body.
