Instrument access device
First Claim
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.

Abstract
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.

12. An instrument access device, comprising:
-
a wound retractor, including; a proximal member, a distal member, and a retractor sleeve extending proximally from the distal member toward the proximal member for retracting laterally the sides of a wound opening, wherein the wound retractor is configured such that retraction is increased by shortening an axial extent of the retractor sleeve between the proximal member and the distal member, and decreased by lengthening the shortened axial extent; 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 proximal section having a first width, a middle section extending distally from the proximal section, the middle section having a second width, the first width being greater than the second width, and a distal section, a proximally facing surface of the distal section having a third width, the third width being greater than the second width and less than the first width, the at least one instrument seal assembly being insertable into the cap and retained to the cap by at least the width difference between the middle section and the distal section and contact between the cap and the middle section. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method of performing a surgical procedure, comprising:
-
inserting a wound retractor into a wound opening, the wound retractor including; a proximal member, a distal member, and a retractor member extending proximally from the distal member toward the proximal member, retracting sides of the wound opening laterally by shortening an axial extent of the retractor member between the proximal member and the distal member, wherein shortening the axial extent includes moving a portion of the retractor member proximal to the proximal member; coupling a cap to the wound retractor; and coupling at least one instrument seal assembly to the cap by; inserting a distal end of the at least one instrument seal assembly into the cap, the distal end including a flange and a distally extending taper, moving a proximal end of the at least one instrument seal assembly toward the cap, at least a portion of the proximal end being wider than a widest part of the flange, and bringing an intermediate portion of the instrument seal assembly into contact with the cap, the 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. - View Dependent Claims (19)
