Retractor
First Claim
1. A surgical wound retractor comprising:
- —
a distal anchoring member for insertion into a wound opening;
a connecting means having an inner wound engaging portion and an outer portion, the wound engaging portion being mounted to the distal anchoring member, the connecting means having an insertion configuration in which the inner wound engaging portion has a reduced radial dimension and a retracting configuration;
an external guide means for the outer portion of the connecting means;
the external guide means being movable relative to the connecting means to shorten the axial extent of the connecting means and thereby bias the wound engaging portion of the connecting member into the retracting configuration to retract the wound opening laterally; and
external anchoring means for anchoring the connecting means to maintain retraction of the opening.

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.

24. A method for retracting a wound opening using a surgical wound retractor comprising a distal anchoring member, a connecting means having a wound engaging portion mounted to the distal anchoring member and an outer portion, an external guide means for the outer portion of the connecting means and an external anchoring means;
- the method comprising the steps of;
—positioning the distal anchoring member to be retained inside a wound opening with the connecting means extending outwardly therefrom through the opening;
moving the external guide means relative to the outer portion of the connecting means to shorten the axial extent of the connecting means and thereby bias the wound engaging portion into a retracting configuration to retract the wound opening; and
anchoring the connecting means to maintain retraction of the wound opening. - View Dependent Claims (25, 26, 27)
