Surgical stapling instrument comprising a magnetic element driver

A surgical stapler, comprising:

• a shaft;
• an end effector movably coupled to said shaft, said end effector comprising:
• a staple cartridge channel configured to receive a staple cartridge;
• a first gear portion;
• and
• an anvil movably coupled to said staple cartridge channel;
• and
• a motor, comprising:
• a housing mounted to said shaft;
• windings configured to generate a magnetic field;
• a magnetic element configured to be rotated by the magnetic field produced by said windings;
• and
• a second gear portion configured to be rotated by said magnetic element, wherein said second gear portion is operably engaged with said first gear portion such that the rotation of said magnetic element is transferred to said end effector.

A surgical stapler, comprising:

• a shaft, comprising:
• a frame;
• and
• a driver rotatable relative to said frame;
• an end effector, comprising:
• a staple cartridge channel configured to receive a staple cartridge;
• an anvil movably coupled to said staple cartridge channel;
• and
• a gear portion, wherein said driver is operably engaged with said gear portion;
• and
• a motor, comprising:
• a first magnetic element mounted to said frame;
• and
• a second magnetic element mounted to said driver, wherein said first magnetic element is configured to generate at least one magnetic field sufficient to displace said second magnetic element relative to said frame and rotate said driver.
