A surgical instrument assembly comprising an end effector, a shaft assembly, a closure drive system, and a firing drive system is disclosed. The surgical instrument assembly further comprises a dual lock configured to engage a closure member and a firing member to prevent the firing member from being advanced distally from a proximal firing stroke position before the closure member is in a distal closure stroke position. The dual lock is further configured to prevent the closure member from being retracted from the distal closure stroke position before the firing member is returned to the proximal firing stroke position after the firing stroke.

Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft assembly extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft assembly including a reciprocating driveshaft disposed within the elongated shaft assembly. The driveshaft may include an internal channel and at least one guide surface shaped and arranged to maintain an orientation of at least one fastener in the channel of the driveshaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft assembly for displacing one or more fasteners within the elongated shaft assembly towards a distal fastener deployment position.

A method for producing a surgical instrument is disclosed. The method comprises obtaining a handle, wherein the handle comprises a distal end comprising a shaft interface surface and a first set of magnetic elements. The method further comprises obtaining a shaft, wherein the shaft comprises a proximal end comprising a handle interface surface, a second set of magnetic elements, and a third set of magnetic elements. The method further comprises attaching the shaft to the handle, wherein the shaft interface surface is configured to engage the shaft at the handle interface surface, wherein an attractive magnetic force is configured to pull the handle towards the shaft when the first set of magnetic elements interact with the second magnetic elements, and wherein a repulsive magnetic force is configured to repel the handle from the shaft when the first set of magnetic elements interacts with the third set of magnetic elements.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.

A method for adjusting the operation of a clip applier using machine learning in a surgical suite is disclosed. The method comprises gathering data during surgical procedures, wherein the surgical procedures include the use of a clip applier comprising a crimping drive configured to be mechanically advanced through a crimping stroke. The method further comprises analyzing the gathered data to determine an appropriate operational adjustment of the clip applier and adjusting the operation of the clip applier to improve the operation of the clip applier.

A method for downloading data from a surgical hub to a surgical instrument is disclosed. The method comprises assembling a first shaft assembly to a handle and downloading a first set of operational data from the surgical hub to the handle once the first shaft assembly is attached to the handle. The method further comprises assembling a second shaft assembly to the handle and downloading a second set of operational data from the surgical hub to the handle once the second shaft assembly is attached to the handle, wherein the second set of operational data is different than the first set of operational data.
