Abstract: Inserts and features to reduce or prevent spline crash in surgical staplers and/or to minimize damage resulting from spline crash in surgical staplers. An insert for a surgical stapler includes a body and spline covers. The body is configured to fit within a bore of a shell assembly and the spline covers extend inward from the body. Each of the spline covers are sized and dimensioned to cap a distal portion of splines of the shell assembly. A shell assembly for a surgical stapler includes shell splines that are disposed on an inner wall of an inner housing portion that defines a bore. The shell splines include a lead spline that has a leading end positioned distal of a leading end of each of the other shell splines.

Abstract: A powered surgical device includes a power source and a motor coupled to the power source. The device may include a reload having a plurality of staples. The device may also include a transmission assembly movable by the motor. The device may also include a sensor configured to monitor operation of the transmission assembly and output sensor data. The device may also include a controller configured to: determine a position of the transmission assembly, and operate the motor based on the position of the transmission assembly to advance the transmission assembly to eject the plurality of staples from the reload. The controller is further configured to stop the motor once the plurality of staples is ejected from the reload for a preset period of time.
