Retractor
First Claim
1. A medical device, comprising:
- a wound protector, including;
a proximal ring,a distal ring, anda sleeve extending between the proximal ring and the distal ring, wherein the distal ring and a distal portion of the sleeve are configured for insertion into an incision, and the proximal ring and a proximal portion of the sleeve are configured for positioning outside of the incision; and
a proximal assembly coupled to the proximal ring, the proximal assembly including;
an outer member coupled to the proximal ring,an inner member, wherein at least part of the inner member is received by the outer member, and the inner member slidably engages the outer member, andan access portion providing a passageway through the proximal assembly.

Abstract
A retractor (101) for retracting the margins of a wound opening (103) comprises an inner anchoring O-ring (105) attached to a cylindrical sleeve (106) at a distal end and a reinforcing O-ring (109) attached to a proximal end of the sleeve (106). The sleeve (106) is led between an inner ring part (110) and a corresponding recess (116) in an outer ring part (111). The outer ring part (111) has anchor formations (120) over which the proximal end of the sleeve (106) is attached to anchor the sleeve (106). To retract the wound opening (103) the sleeve (106) is pulled while the guide rings (110, 111) are moved against the tissue surrounding the wound opening (103). This pulls the inner O-ring (105) against the inside of the tissue adjacent the wound opening (103), and retracts the wound opening (103). The sleeve (106) is manipulated locally for maximum retraction efficiency.

12. A medical device, comprising:
-
a wound protector, including; a proximal ring, a distal ring, and a sleeve extending between the proximal ring and the distal ring, wherein the distal ring and a distal portion of the sleeve are configured for insertion into an incision, and the proximal ring and a proximal portion of the sleeve are configured for positioning outside of the incision; and a proximal assembly coupled to the proximal ring, the proximal assembly including; a base coupled to the proximal ring, the base having a proximal surface and a distal surface, and an access portion configured to provide passage through the base, wherein the access portion extends proximally from the proximal surface of the base, the access portion has a proximal end with a proximal aperture, and the proximal aperture is spaced in a proximal direction from the proximal surface of the base. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method of retracting and sealing an incision for laparoscopic procedures, comprising:
-
making an incision in a patient; positioning a wound retractor system proximate the incision, the wound retractor system including; a distal ring, a proximal ring, a sleeve extending between the distal ring and the proximal ring and fixedly coupled to both the proximal ring and the distal ring, and a proximal receiver including a recess; inserting the distal ring through the incision such that the sleeve extends through the incision and the proximal ring is located outside of the incision; retracting the incision with the sleeve; coupling a portion of the proximal ring to the recess of the proximal receiver so that the receiver restricts movement of the proximal ring and an actual length of the sleeve between the distal ring and the proximal receiver is shortened; and coupling an access device to the proximal receiver. - View Dependent Claims (19, 20)
