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

TL;DR: In this paper, an end effector is disclosed comprising a cartridge channel, a staple cartridge positionable in the cartridge channel and a firing assembly configured to lock itself if the staple cartridge is not positioned in the chamber.
Patent
Surgical tool assemblies with closure stroke reduction features
TL;DR: In this paper, a surgical tool assembly that includes a surgical end effector that has first and second jaws that are movable between a fully open position and a fully closed position relative to each other is configured to move through a first closure stroke distance upon application of a closure input motion.
Patent
Closure members with cam surface arrangements for surgical instruments with separate and distinct closure and firing systems
TL;DR: In this article, a surgical instrument with separate closure and firing systems is presented, where the hollow closure member is configured to move axially between an unactuated position and closure positions and the firing member is supported for axial travel between a starting position in hollow closure and an ending position in the surgical end effector.
Patent

Patent
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.
