    Abstract: Sealing assemblies and methods are disclosed for sealing a surgical instrument having an internal drive shaft subject to lateral displacement. A sealing assembly includes a rigid portion shaped to interface with an instrument shaft of the surgical instrument. A laterally oriented slot is open at a radially perimeter location and configured to receive an o-ring seal via the perimeter location. Apertures are disposed on opposing sides of the slot and open to the slot. The apertures are configured to receive the drive shaft there through and are larger than the drive shaft to accommodate lateral displacement of the drive shaft. The slot includes opposing internal sides spaced to interface with opposed axial surfaces of the o-ring seal. The seal inhibits axial transmission of an insufflated gas and/or bodily fluids while accommodating lateral displacement of the drive shaft.

    Abstract: A surgical instrument with a stowing knife blade includes an elongated shaft, an end effector coupled to the shaft and including two opposed jaws, a housing included in one of the jaws, a first member mounted in the housing and movable distally, a knife pivotally coupled with the first member, and a second member. The knife is configured to cut when advanced distally. The first and second members are moved distally at the same rate during a cutting motion of the knife and the second member blocks a rotation of the knife relative to the first member during the cutting motion of the knife. After moving through the first distance, relative movement between the first and second members occurs so as to permit or induce the previously blocked rotation of the knife so that the knife can be stowed.

    Abstract translation: 具有收纳刀片的手术器械包括细长轴，连接到所述轴并且包括两个相对的钳口的端部执行器，包括在一个钳口中的壳体，安装在壳体中并可向远侧移动的第一构件，可枢转地联接的刀 与第一个成员和第二个成员。 刀具配置为在远端进行切割。 在刀的切割运动期间，第一和第二构件以相同的速度向远侧移动，并且在刀的切割运动期间第二构件阻挡刀相对于第一构件的旋转。 在移动第一距离之后，发生第一和第二构件之间的相对运动，以允许或引起先前阻止的刀的旋转，使得刀可以被收起。

    Abstract: A motor assembly is presented. A motor assembly can include at least one motor; a memory to store calibrated parameters related to the at least one motor; and electronics coupled to the memory, the at least one motor, the electronics including interfaces to couple with a clamping device and a system to control the operation of the at least one motor. The calibrated parameters are determined for the at least one motor with a procedure that includes performing an initial calibration of the at least one motor; wearing in the at least one motor; performing a final calibration of the at least one motor; and storing calibration data in the memory. In some embodiments, the at least one motor can include a clamping motor and/or a firing motor. In some embodiments, lifetime parameters are stored in the memory.
