An instrument access device comprises first, second and third instrument seals for sealing around instruments extended through the device. The seals have respective connector sleeves. Each sleeve connects a base to one of the instrument seals. The device also comprises two insufflation/desufflation ports. Each of the ports comprises a connector extending from the base, a tube extending from the connector, a luer connector and a removable cap. The luer connector is used for connection to any suitable supply line for insufflation gas or for discharge if insufflation gas. In use, the insufflation/desufflation ports facilitate independent control of insufflation and desufflation as may be required during a surgical procedure. Access sleeve at the proximal end is cut-off, folded over the inner proximal ring and is held in place between the base and the inner proximal ring when the base is fitted. The proximal end of the sleeve that is generated when the sleeve is pulled upwardly to retract an incision is removed from the field of use. |

1. An instrument access device, comprising:
a wound retractor, including:
a proximal member,a distal member, anda retractor sleeve extending proximally from the distal member toward the proximal member for retracting laterally the sides of a wound opening, wherein the retractor sleeve is configured such that the retraction is applied by shortening an axial extent of the retractor member between the proximal member and the distal member; a cap removably coupled to the wound retractor; and at least one instrument seal assembly removably coupled to the cap, the at least one instrument seal assembly including:
a distal end including a flange and a distally extending taper,a proximal end, at least a portion of the proximal end being wider than a widest part of the flange, andan intermediate portion extending between the flange and the portion of the proximal end, the intermediate portion having a narrower width than each of the widest part of the flange and the portion of the proximal end, wherein the intermediate portion contacts the cap for removably coupling the at least one instrument seal assembly to the cap. |
