Patent ID: 7341558

Claim:
A surgical retractor for use within a body cavity, comprising: a) an elongate swivel having a first end and a second end, said first end of said swivel having a non-circular keyway means for engaging a key on a deployment tool; b) a first length of string extending from said first end of said swivel; c) a second length of string extending from a point substantially midway between said first end and said second end, said second length of string having a free end which does not re-enter the swivel, said first and second lengths of string having sufficient length such that either may be pulled from outside the body cavity, such that pulling on said second length of string causes said swivel to swivel off the key on the deployment tool and be oriented substantially perpendicular to said second length of string, and pulling on said first length of string causes said swivel to be oriented substantially coaxial to said first length of string.
