Wound retractor
First Claim
1. A surgical wound retracting device, comprising:
- a resilient distal ring;
a proximal ring;
a wound retracting sleeve configured to contact and retract the wound when the device is in use, the wound retracting sleeve extending at least between the proximal ring and the distal ring;
an outer radial member; and
a release member located radially within a portion of the wound retracting sleeve, and extending between the proximal ring and the outer radial member, wherein when the release member is in use, a pulling force on the release member applies a pulling force on the distal ring to assist in removing the device from a patient.

Abstract
A wound retractor (320) comprises a distal ring (3) for insertion through a wound opening (6), a proximal ring (4) for location externally of the wound opening (6), a valve (10) mounted to the proximal ring (4), and a sleeve (2) for retracting laterally the sides of the wound opening (6). The wound retractor (320) also comprises a flexible release member (81) for releasing the distal ring (3) from a retracting configuration for removal of the distal ring (3) from the wound opening (6). A first end (301) of the release member (81) is attached to the valve housing (102), the release member (81) loops around the distal ring (3), and a second end (302) of the release member (81) is movable relative to the proximal ring (4) to release the distal ring (3) from the retracting configuration.

7. A wound retracting device, comprising:
-
a distal ring; a proximal ring; a wound retracting sleeve configured to contact and exert a retracting force on the wound when the device is in use, the wound retracting sleeve extending at least from the proximal ring to the distal ring; a proximal member assisting in controlling the retracting force exerted by the wound retracting sleeve when the device is in use; and a release member, including a cord, extending from the distal ring proximally to the proximal ring, and extending between the proximal ring and the proximal member. - View Dependent Claims (8, 9, 10, 11)
