US Patent 10327765 Drive systems for surgical instruments

A surgical instrument for use with a remotely actuatable system capable of generating control motions is disclosed. The surgical instrument comprises an elongate shaft assembly and an end effector extending from the elongate shaft assembly. The elongate shaft assembly is configured to be coupled to the remotely actuatable system. The end effector comprises an elongate channel configured to receive a staple cartridge, an anvil movably coupled to the elongate channel, and an actuating member operably supported within the elongate shaft assembly. The actuating member is configured to effect at least one motion at the end effector in response to the control motions. The actuating member is advanceable from an initial position a first distance in response to the control motions. The actuating member is retractable a second distance through the initial position in response to the control motions. The second distance is greater than the first distance.
