Abstract
An apparatus (650) for inserting a distal ring (9) of a wound retractor device (2) through a wound opening comprises a bladeless tip (641) for creating the wound opening by forcing tissue apart, and a conveying device (5) for conveying the distal ring (9) through the wound opening. The conveying device (5) comprises a hook element (6) for engaging the distal ring (9) to convey the distal ring (9) through the wound opening, and a receiver housing (651) for receiving a seal (652) and a proximal ring (653) of the wound retractor device (2) to hold the seal (652) and the proximal ring (653) externally of the wound opening, and thus maintain a sleeve portion of the wound retractor device (2) in tension, during conveying of the distal ring (9) through the wound opening.
