Wound retractor device
First Claim
1. A wound retractor device comprising:
- a distal member for insertion into a wound opening;
a proximal member for location externally of the wound opening; and
a connecting member extending at least between the distal member and the proximal member;
at least part of the connecting member being movable relative to the proximal member to shorten the length of the connecting member located between the distal member and the proximal member and thereby retract laterally the sides of the wound opening.

Abstract
A wound retractor device (1) comprises a distal ring member (2) for insertion into a wound opening (3), a proximal ring member (4) for location externally of the wound opening (3), and four strap members (5) extending between the proximal ring member (4) and the distal ring member (2). The four separate strap members (5) are axially movable relative to the distal ring member (2) and relative to the proximal ring member (4). The distal ring member (2) comprises four slots (6), with each strap member (5) positioned extending through a slot (6). The slots (6) thus act as passageways through which the strap members (5) may extend, and in this manner the slots (6) guide movement of the strap members (5) relative to the distal ring member (2). The proximal ring member (4) also comprises four slots (7) which act as passageways to guide movement of the strap members (5) relative to the proximal ring member (4). In use, the distal ring member (2) is inserted into the wound opening (3), and the proximal ring member (4) is located externally of the wound opening (3). The second end (10) of each strap member (5) is then gripped, and a pulling force is exerted to retract laterally the sides of the wound opening (3).

54. A method of retracting a wound opening, the method comprising the steps of:
-
providing a wound retractor device comprising a distal member, a proximal member, and a connecting member extending at least between the distal member and the proximal member;
inserting the distal member into the wound opening, and locating the proximal member externally of the wound opening; and
moving at least part of the connecting member relative to the proximal member to shorten the length of the connecting member located between the distal member and the proximal member and thereby retract laterally the sides of the wound opening. - View Dependent Claims (55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)
