Surgical device for retracting and/or sealing an incision
First Claim
Patent Images
1. A wound protector and retractor device, comprising:
- a longitudinal axis;
a distal ring;
a proximal ring;
a sleeve extending at least between the distal ring and the proximal ring and proximal to the proximal ring, the sleeve being axially movable relative to the proximal ring to shorten an axial length of the sleeve located between the distal ring and the proximal ring, wherein a portion of the sleeve is slidingly received about a portion of the proximal ring during shortening of the axial length of the sleeve; and
a securing arrangement configured to substantially fix the axial length of the sleeve located between the distal ring and the proximal ring at a desired length.

Abstract
A wound protector retractor comprises an inner O-ring for insertion through a wound opening and a connecting sleeve extending between the O-ring and outer mounting means. The outer means are provided by rings between which the sleeve is led. The rings are rotated relative to each other and the inner ring to form a centralised lumen of reduced cross section and to shorten the axial extent of the sleeve. A wound is both retracted and protected.

21. A method for retracting an incision comprising:
-
making an incision in a patient; providing a wound retractor comprising a central longitudinal axis, a distal ring, a proximal ring, and a sleeve extending at least between the distal ring and the proximal ring, the sleeve being axially movable relative to the proximal ring and proximal to the proximal ring; inserting the distal ring through the incision such that the sleeve extends through the incision and the proximal ring is located outside of the incision; sliding a portion of the sleeve against a portion of the proximal ring to shorten an axial length of the sleeve located between the distal ring and the proximal ring; and securing the sleeve to maintain the shortened axial length of the sleeve located between the distal ring and the proximal ring. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
