1. A wound retractor system comprising:
- —
a wound retractor includinga retracting member configured for retracting a wound opening,a distal member configured for insertion through the wound opening; and
an insertion tool for deploying the distal member into the wound opening, the insertion tool including a receiver configured to receive a portion of the wound retractor, wherein at least a portion of the receiver is configured to deform the distal member by elongating a dimension of the distal member in a first direction, and shortening a dimension of the distal member in a second direction, wherein the insertion tool includes a rounded distal dip tip.

Abstract
A wound retractor system comprises a retractor having a distal ring 91 and a retracting sleeve 4 extending from the ring. An insertion tool 120 has a distal groove 122 to hold the ring for insertion of the ring through a small incision 90 in the abdominal wall 97. The retractor may be used for retracting an incision to receive an instrument therethrough. A seal or valve may be mounted to the retractor through which an instrument can pass.

16. A method for retracting an incision comprising the steps of:
- —
making a wound opening in a body wall; providing a wound retractor including a distal member, and a retracting member extending from the distal member; providing an insertion tool having a receiver for receiving a portion of the wound retractor, and for deforming opposing sides of the distal member to elongate a dimension of the distal member in a first direction, and shorten a dimension of the distal member in a second direction, the insertion tool including a rounded distal tip; inserting the portion of the wound retractor into the receiver; inserting the insertion tool, with the portion of the wound retractor inserted into the receiver, through the wound opening; deploying the wound retractor in the wound opening; and withdrawing the insertion tool from the wound opening. - View Dependent Claims (17, 18)

19. A wound retractor system comprising:
- —
a wound retractor including a retracting member configured for retracting a wound opening, and including a sleeve configured to line the wound opening, a proximal member for location externally of the wound opening, the proximal member being movable relative to the retracting member to shorten an axial extent of the retracting member to laterally retract the wound opening, a distal member configured for insertion through the wound opening; and an insertion tool for deploying the distal member into the wound opening, the insertion tool including a receiver configured to receive a portion of the wound retractor, wherein at least a portion of the receiver is configured to deform the distal member by elongating a dimension of the distal member in a first direction, and shortening a dimension of the distal member in a second direction.
