A rotary to linear actuator, comprises a drive crankarm that rotates in a first axis of rotation; a first and second gearset connected to the drive crankarm through a second crankarm; and a piston captured between the first gearset and the second gear set, wherein the first and second gearsets rotate a crankarm connected to one end of the piston, wherein the piston is caused to move linearly upon rotation of the crankarm.

Rotary drive arrangements for surgical instruments

In various embodiments, a surgical instrument for use with a robotic surgical system is disclosed. The surgical instrument comprises a mounting portion, an elongate shaft, and an end effector. The end effector comprises a first jaw, a second jaw, a staple cartridge, a closure member, a drive screw, a thrust bearing, a coupling member, and a sled. The closure member is configured to move the second jaw from an open position toward a closed position in response to an output motion. The drive screw is configured to apply a distal force to the coupling member when the drive screw is rotated. The coupling member is configured to engage the second jaw and retain the second jaw at a distance relative to the first jaw during a firing stroke. The sled ejects staples from the staple cartridge when the sled is moved by the coupling member during the firing stroke.

Stapling assembly comprising a firing lockout

A stapling assembly comprising a first jaw, a second jaw, an elongate channel configured to receive a staple cartridge, a firing member, a biasing member, and a lock member movable between locked and unlocked positions is disclosed. One of the first jaw and the second iaw is movable relative to the other of the first jaw and the second jaw between an open position and a closed position. The staple cartridge comprises staples and a sled configured to be advanced by the firing member during a firing stroke. The firing member comprises a cutting edge, a first camming member configured to engage the first jaw during the firing stroke, and a second camming member configured to engage the second jaw during the firing stroke. The firing member is prevented from performing the firing stroke when the stapling assembly is in one of a plurality of lockout states.
