摘要：
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 (940a,b) which can be selectively activated, or polarized, to generate a magnetic field sufficient to motivate a second magnetic element, such as a permanent magnet (949) and/or an iron core, for example, mounted to the end effector (906). 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.
