Abstract
Surgical instruments and cartridges for cutting and fastening tissues and organs such as vessels are disclosed. In various non-limiting forms, the surgical instrument includes a first jaw that operably supports a substantially flexible elongated tissue closure assembly therein. A second jaw is movably supported relative to the first jaw and is selectively movable between open and closed positions in response to opening and closing motions applied thereto. A closure retraction assembly is configured to selectively apply cinching motions to the substantially flexible elongated tissue closure assembly.
Claims23
A surgical fastening instrument, comprising:
- a first jaw operably supporting a substantially flexible elongated tissue closure assembly therein comprising a first suture strip including a first end and a second end, wherein the first suture strip comprises an aperture in the first end, and wherein the second end is configured to be pulled through the aperture in the first end;
- a second jaw movably supported relative to the first jaw and being selectively movable between open and closed positions in response to opening and closing motions applied thereto;
- and
- a closure retraction assembly configured to selectively pull the second end of the first suture strip through the aperture in the first end of the first suture strip to cinch the first suture strip around tissue received between the first and second jaws.
A surgical fastening instrument, comprising:
- a first jaw operably supporting a substantially flexible elongated tissue closure assembly therein, said substantially flexible elongated tissue closure assembly comprising:
- a first absorbable suture comprising a first substantially U-shaped flexible first body portion terminating in a first locking end that defines a first locking aperture and a first hook-shaped end spaced from said first locking aperture and in substantial registration therewith;
- and
- a second absorbable suture comprising a second substantially U-shaped flexible second body portion terminating in a second locking end that defines a second locking aperture and a second hook-shaped end spaced from said second locking aperture and in substantial registration therewith, and wherein said surgical fastening instrument further comprises:
- a second jaw movably supported relative to said first jaw and being selectively movable between open and closed positions in response to opening and closing motions applied thereto;
- and
- a closure retraction assembly configured to selectively apply cinching motions to said substantially flexible elongated tissue closure assembly.
A surgical fastening instrument, comprising:
- a first jaw operably supporting a tissue securing assembly therein comprising a first strip including a first end and a second end, wherein the first strip comprises an aperture in the first end, and wherein the second end is configured to be pulled through the aperture in the first end;
- a second jaw, wherein one of the first jaw and the second jaw is movable between an open position and a closed position;
- and
- a closure assembly configured to selectively pull the second end through the aperture in the first end to cinch the tissue securing assembly around tissue received between the first and second jaws.
A surgical fastening instrument, comprising:
- a first jaw operably supporting a tissue securing assembly therein, the tissue securing assembly comprising:
- a first suture comprising a first flexible body portion terminating in a first locking end that defines a first locking aperture and a first hook-shaped end spaced from the first locking aperture;
- and
- a second suture comprising a second flexible body portion terminating in a second locking end that defines a second locking aperture and a second hook-shaped end spaced from the second locking aperture;
- a second jaw, wherein one of the first jaw and the second jaw is movable between an open position and a closed position;
- and
- a closure retraction assembly configured to selectively apply a cinching motion to the tissue securing assembly.
