Robotically-controlled shaft based rotary drive systems for surgical instruments
View Patent ↗A stapling system comprising a housing is disclosed. The housing comprises a first rotatable drive disk. The stapling system further comprises a closure member configured to transmit a closing motion from the first rotatable drive disk to an anvil to move the anvil into a closed position. The stapling system further comprises a second rotatable drive disk, wherein the second rotatable drive disk is operable independently of the first rotatable drive disk and is configured to transmit a second operative motion. The stapling system further comprises a firing member configured to perform a firing stroke in response to the second operative motion. The stapling system further comprises a control system that assures that the closing motion and the firing stroke are separate and distinct and that prevents the firing stroke from occurring prior to the completion of the closing motion.
1. A stapling system, comprising:
a housing comprising a first rotatable drive disk, wherein said first rotatable drive disk is rotatable about an axis to complete a rotation about said axis;
an elongate shaft extending from said housing;
an end effector, comprising:
a jaw configured to support a staple cartridge; and
an anvil rotatable relative to said jaw between an open position and a closed position;
a closure member configured to transmit a closing motion from said first rotatable drive disk to said anvil to move said anvil into said closed position;
a second rotatable drive disk, wherein said second rotatable drive disk is operable independently of said first rotatable drive disk and is configured to transmit a second operative motion;
a firing member configured to perform a firing stroke in response to said second operative motion; and
a control system that assures that said closing motion and said firing stroke are separate and distinct and that prevents said firing stroke from occurring prior to the completion of said closing motion.
2. The stapling system of claim 1 , wherein said axis is transverse to a longitudinal axis defined by said elongate shaft.
3. The stapling system of claim 1 , further comprising said staple cartridge.
4. The stapling system of claim 3 , wherein said staple cartridge is removably replaceable within said jaw.
5. The stapling system of claim 1 , further comprising a rotary motion generator configured to rotate said first drive disk.
