Abstract: An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft extending between the body and the end effector. The end effector includes a pair of jaws and at least one electrode operable to deliver RF energy to tissue clamped between the jaws. The cutting member is operable to cut tissue clamped between the jaws. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. The articulation section may include beads, segments, asymmetric features, preformedly bent features, an integral hinge, a helical cutout or spring, clevis features, an angled joint, a beaded actuation linkage, and/or an offset pivot, among other things. The device may also include a crimped cutting member, a retroacting cutting member, dual pivoting jaws, and/or a wire tensioning assembly.

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.

Abstract: In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.
