Instrument access device
First Claim
1. An instrument access device, comprising:
- a wound retractor, including;
a proximal ring,a distal ring, anda retractor sleeve extending proximally from the distal ring to the proximal ring, wherein at least a portion of the retractor sleeve is configured to extend proximally of the proximal ring; and
a proximal assembly, including;
an instrument seal assembly mounted to the proximal ring, wherein the instrument seal assembly includes a plurality of tubular portions, each of the plurality of tubular portions having a single and distinct sealing element at an end of each of the plurality of tubular portions, wherein a distal end of the instrument seal assembly includes at least one surface that faces radially outwardly away from a central longitudinal axis of the wound retractor, and wherein the instrument seal assembly includes a flexible base mounted to the proximal ring, and the plurality of tubular portions extend proximally from the flexible base; and
an outer ring mounted to the proximal ring, wherein the outer ring includes at least one surface that faces radially inwardly toward the central longitudinal axis of the wound retractor, wherein the at least one surface of the outer ring faces the at least one surface of the distal end of the instrument seal assembly.

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.

8. An instrument access device, comprising:
-
a wound retractor, including; a proximal ring, a distal ring, and a retractor sleeve extending proximally from the distal ring to the proximal ring; and a proximal assembly mounted to the proximal ring, the proximal assembly including; an instrument seal assembly, wherein the instrument seal assembly includes a plurality of tubular portions, each of the tubular portions having a sealing element at an end thereof, and wherein the sealing elements are laterally spaced from each other and do not overlap in an axial direction, and an outer ring extending radially around;
(i) an outer periphery of the proximal ring, and (ii) an outer periphery of a distal end of the instrument seal assembly,wherein a portion of the retractor sleeve is configured to extend into a region between (i) a radially outermost edge of the proximal ring, and (ii) the outer ring. - View Dependent Claims (9, 10, 11, 12, 13)

14. An instrument access device, comprising:
-
a wound protector, including; a proximal ring, a distal ring, and a sleeve extending proximally from the distal ring to the proximal ring for protecting lateral sides of a wound opening; and an instrument seal assembly mounted to the proximal ring, the instrument seal assembly including; a first elongate tubular portion having a free end, a first sealing element coupled to the first elongate tubular portion, the first sealing element having a central longitudinal axis extending therethrough, a second elongate tubular portion having a free end, and a second sealing element coupled to the second elongate tubular portion at the free end of the second elongate tubular portion, the second sealing element having a central longitudinal axis extending therethrough, wherein the central longitudinal axis of the first sealing element is parallel to the central longitudinal axis of the second sealing element, wherein the wound protector includes a central longitudinal axis, and the central longitudinal axes of the first sealing element and the second sealing element are offset from the central longitudinal axis of the wound protector. - View Dependent Claims (15, 16, 17, 18, 19)
