Self-contained gas powered surgical stapler
TLDR
In this paper, a surgical stapler powered by a relatively low pressure gas supply contained in the staplers is described, which has a mechanical linkage between the pneumatic actuator and the staple driver with a differential mechanical advantage to match the substantially constant force provided by the pNE to the different forces required to first advance and then form the staple.Abstract:
A surgical stapler powered by a relatively low pressure gas supply contained in the stapler. The stapler has a mechanical linkage between the pneumatic actuator and the staple driver with a differential mechanical advantage to match the substantially constant force provided by the pneumatic actuator to the different forces required to first advance and then form the staple. This mechanical linkage allows use of a relatively small low pressure actuator and also substantially increases the efficiency with which the gas supply is utilized.read more

Surgical instrument comprising an articulation system ratio
TL;DR: In this paper, a shaft assembly is disclosed comprising a shaft including a proximal end, a distal end and a longitudinal axis extending between the proximal and distal ends.
Patent
Surgical instruments with open and closable jaws and axially movable firing member that is initially parked in close proximity to the jaws prior to firing
TL;DR: In this paper, a surgical instrument comprising an articulatable end effector that is selectively articulated about an articulation axis is described. And each jaw engagement feature is configured such that a portion thereof is positioned between the jaw pivot axis and the articulation axes when the axially movable firing member is in the starting position.
Patent
Surgical instruments with articulatable end effector with axially shortened articulation joint configurations
TL;DR: In this article, the second jaw is pivotable relative to the first jaw about a pivot axis by an axially movable closure member, and a first distance between the pivot axis and an area of camming contact between a closure member cam surface on the closure member and a jaw cam surface is divided by a second distance from the articulation axis to the proximal most fastener location.

TL;DR: A staple having a crown, a deformable leg extending from the crown, and a spring that compresses tissue between the spring and the deformable member is described in this paper. But this is not the case in this paper.
Patent
Surgical end effectors with improved jaw aperture arrangements
TL;DR: In this article, a surgical end effector that includes a first jaw and a second jaw that is pivotally attached to the first jaw for pivotal travel between a fully open position and a fully closed position is described.

Cartridge and powering instrument for stapling skin and fascia
TL;DR: In this paper, a disposable staple cartridge is used to insert a plurality of staples on a flexible belt and adapted to inject and form the staples, singly, into the disunited skin or fascia of a patient.
Patent
Surgical stapler for skin and fascia
TL;DR: In this article, a gas-powered instrument for applying surgical staples to effect the joining of disunited skin or fascia is presented, which is powered by a gas under pressure originating from a gas filled tank.
Patent
Surgical stapling instrument
TL;DR: A pusher bar and knife assembly including a pair of pusher bars and a central knife carrier moves longitudinally relative to the jaws to eject staples sequentially from the magazine and form laterally spaced staple rows in tissue gripped between the jaws while the knife cuts the tissue along a line between the staple rows.
Patent
Three-stage surgical instrument
TL;DR: In this article, a shifter dog mechanism is used to ensure the completion of a ligating, suturing and dividing cycle to avoid jamming the staple-carrying cartridge.
Patent
Surgical instrument for intraluminal anastomosis
TL;DR: An instrument for use by surgeons particularly in cases involving resection and anastomosis of vascular and digestive tract organs is described in this paper.The instrument is dimensioned for insertion of the principal parts of the instrument into the open ends of or through stab wounds in the lumena after resection by stapling the tissue entirely around the stoma which is formed by an endless knife, illustrated as annular.
