1. A surgical device, comprising:

  • a wound retractor, comprising;

    a distal ring,a proximal ring, anda wound retracting sleeve extending at least between the distal ring and the proximal ring, wherein the wound retractor is for retracting a wound opening via shortening of an axial extent of the wound retracting sleeve that extends between the distal ring and the proximal ring, and wherein the proximal ring and the wound retracting sleeve are separate elements that are engaged such that positioning of a proximal portion of the wound retracting sleeve relative to the proximal ring is adjustable to shorten the axial extent of the wound retracting sleeve; and

    a sealing assembly coupled to the wound retractor, wherein the sealing assembly comprises;

    an access sleeve having a proximal end, the access sleeve extending proximally from the proximal ring to the proximal end, anda valve member at the proximal end of the access sleeve, the valve member being movable between a first position and a second position, wherein at least a proximal end of the valve member is;

    a first distance from a proximal end of the proximal ring in the first position, anda second distance from the proximal end of the proximal ring in the second position, the first distance being greater than the second distance, andwherein material forming the access sleeve inherently biases the valve member toward moving from the first position to the second position.
