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 plurality of straps,each strap extending from the proximal member to the distal member and from the distal member to the proximal member to form a double layer configuration,each strap being movably connected to the distal member, andeach strap being movable relative to the proximal member to shorten the length of the strap located between the distal member and the proximal member to 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).

12. A method of retracting a wound opening with a wound retractor device comprising a distal member, a proximal member, and a plurality of straps, each strap extending from the proximal member to the distal member and from the distal member to the proximal member to form a double layer configuration, the method comprising:
-
inserting the distal member into the wound opening, and locating the proximal member externally of the wound opening; and moving each strap relative to the proximal member and the distal member to shorten the length of the strap located between the distal member and the proximal member to retract laterally the sides of the wound opening. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A wound retractor device comprising:
-
a distal ring for insertion into a wound opening; a proximal ring for location externally of the wound opening; and a plurality of straps, each strap including a first end and a second end, the first end being fixedly connected to the proximal ring and the second end being slidably connected to the proximal ring, each strap extending from the proximal ring to the distal ring and from the distal ring to the proximal ring to form a double layer configuration, each strap being slidably connected to the distal ring, and sliding a strap relative to the proximal ring shortens the length of the strap located between the distal ring and the proximal ring to retract laterally the sides of the wound opening. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
