摘要

An instrument access port comprises a retractor ( 811 ) for retracting the sides of an incision ( 813 ) and a valve ( 829 ) for sealing around an instrument ( 814 ) inserted through the retracted incision ( 813 ). The retractor ( 811 ) comprises a distal member for insertion into the incision ( 813 ), a proximal member for location externally of the incision ( 813 ) and a retracting member for extending between the distal member and the proximal member. The valve ( 829 ) is coupled to the retractor ( 811 ) to define a low profile sealed instrument access port.
