Surgical suture and associated anchoring mechanism for tissue retraction
First Claim
1. A tissue retractor for displacing body tissue during surgery, said tissue retractor comprising:
- a tissue piercing member;
a suture line coupled to said tissue piercing member;
a surgical platform;
a fixed element, said fixed element being fixably attached to said surgical platform;
a movable element, said movable element being movable relative to said fixed element between an anchoring configuration wherein said movable and fixed elements are in a substantially proximal relationship relative to each other and a releasing configuration wherein said movable and fixed elements are in a substantially spaced relationship relative to each other;
said fixed and movable elements being configured and sized to be able to mechanically interact with each other for frictionally locking a portion of said suture line therebetween when said movable element is in said anchoring configuration.

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).

26. A suture line anchoring device for anchoring a portion of a suture line to a surgical platform, said anchoring device comprising:
-
a first element, said first element defining a first contact location for contacting said portion of said surgical suture line;
a second element, said second element defining a second contact location for contacting said portion of said surgical suture line;
said first and second elements being configured, sized and coupled to said surgical platform for allowing the distance between said first and second contact locations to vary between an anchoring configuration wherein said first and second contact locations are in a substantially proximal relationship relative to each other and a releasing configuration wherein said first and second contact locations are in a substantially spaced relationship relative to each other;
said first and second contact locations being also configured and sized to be able to mechanically interact with each other for frictionally locking said portion of said suture line therebetween when in said anchoring configuration. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
