Abstract
The present invention provides a tissue retractor (2) for displacing body tissue during surgery consisting of a tissue piercing member such as a surgical needle (20), a wire-like filament such as a suture line (23) affixed to the surgical needle (20), a fixed element such as an anchoring port (90) being associated with a stable surgical platform such as a sternum retractor (1), and a movable element such as an anchoring plug (25) cooperating with anchoring port (90) to engage a portion of suture line (23) after the suture line (23) is threaded through the body tissue with the surgical needle (20) and after the suture wire (20) is tension to effect a predetermined displacement of the body tissue. The predetermined displacement of body tissue is maintained by retention of the engaged portion of suture line (23) by the fixed anchoring portion (90) and the movable anchoring plug (25).
