Abstract
A surgical stapler for applying a suture to tissue includes a first jaw and a second jaw configured to receive a cartridge. An actuation mechanism translates a drive member distally through the first and second jaws to apply staples to tissue such that a suture, in combination with the staples, forms a purse string when the stapler activated. The cartridge includes a first upper portion and a second lower portion.
Claims21
A surgical stapler for applying a suture to tissue, the surgical stapler comprising:
- an elongated shaft having a distal end and a proximal end;
- an end effector having a first jaw with a first distal opening and a second jaw with a second distal opening;
- a cartridge removably coupled to the end effector and having a first upper portion sized to fit into the first distal opening of the first jaw and having a first channel for receiving a suture and a second lower portion sized to fit into the second distal opening of the second jaw and having a second channel for receiving the suture, wherein the first and second channels are configured to form the suture into a loop;
- a drive member configured to translate distally through the end effector to apply staples and the suture to tissue;
- and
- an actuation mechanism configured to translate the drive member distally through the end effector.
A surgical stapler for applying a suture to tissue, the surgical stapler comprising:
- an elongated shaft having distal and proximal ends;
- a cartridge having an upper portion and a lower portion, the upper portion comprising a central channel, a first lateral channel disposed laterally outward from a first side of the central channel and a second lateral channel disposed laterally outward from a second opposing side of the central channel, the cartridge further comprising a first shuttle configured to translate longitudinally through the central channel and the first and second lateral channels of the upper portion;
- an end effector having a first jaw configured to receive the upper portion of the cartridge and a second jaw configured to receive the lower portion of the cartridge;
- a drive member configured to translate distally through the central channel of the cartridge to apply staples and a suture to tissue;
- an actuation mechanism configured to translate the drive member distally through the end effector;
- and
- wherein the first and second jaws are movable between an open position, wherein the jaws define an angle therebetween, to a partially closed position, wherein the jaws are substantially parallel with each other and have a first gap therebetween, to a closed position, wherein the jaw are substantially parallel to each other and have a second gap therebetween, wherein the second gap is smaller than the first gap.
