SURGICAL STAPLING INSTRUMENT COMPRISING A MAGNETIC ELEMENT DRIVER
First Claim
1. 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; and
an anvil movably coupled to said staple cartridge channel; and
a solenoid, comprising;
a housing mounted to said shaft;
windings configured to generate a magnetic field; and
a magnetic element mounted to said end effector, wherein said magnetic field is configured to displace said magnetic element and articulate said end effector relative to said shaft.

Abstract
In various embodiments, a surgical stapling instrument can comprise a plurality of magnetic elements configured to articulate an end effector of the surgical instrument. The surgical instrument can comprise at least one electromagnet which can be selectively activated, or polarized, to generate a magnetic field sufficient to motivate a second magnetic element, such as a permanent magnet and/or an iron core, for example, mounted to the end effector. In certain embodiments, a surgical stapling instrument can comprise a plurality of magnetic elements configured to open and/or close an end effector of the surgical instrument. In at least one embodiment, a surgical stapling instrument can comprise a plurality of magnetic elements configured to advance and/or retract a firing bar, cutting member, and/or staple sled within the surgical instrument in order to incise and/or staple tissue positioned within an end effector of the surgical instrument.
