    Abstract: Surgical systems and related methods for detecting whether a surgical instrument lacks a surgical cartridge in an unfired condition. A method of detecting that a surgical instrument lacks a surgical cartridge in an unfired condition mounted to the surgical instrument includes commanding a movement of the actuation output in a direction opposite to a firing direction for the surgical cartridge, detecting that an actuation amount of the actuation output as a result of the commanded movement is at or above a threshold actuation amount, and in response to detecting that the actuation amount of the actuation output is at or above the threshold actuation amount, determining that the surgical instrument lacks a surgical cartridge in the unfired condition mounted to the surgical instrument.

    IPC: A61B34/00

    Abstract: A surgical system includes a dynamic preload tension feature for a tensioning element that actuates a distal end component of a surgical instrument. The surgical instrument includes a chassis at a proximal end of the surgical instrument, drive components mounted in the chassis, a distal end component at a distal end of the surgical instrument, a flexible tensioning element coupled between a first of the drive components and the distal end component, and a dynamic preload tensioner mounted in the chassis and coupled to a second of the drive components. The flexible tensioning element extends along a path. The dynamic preload tensioner is configured to be driven by the second of the drive components to be moved relative to the chassis and is positioned to change the path of the flexible tensioning element as the dynamic preload tensioner moves relative to the chassis.

    Abstract: Surgical systems and related methods verify the presence of an unfired surgical cartridge mounted to a surgical instrument. The cartridge includes an input that is actuated in a firing direction to operate the cartridge. An actuation input that is limited to less than or equal to a predetermined magnitude is generated. The actuation input includes at least one of a torque or a force. The actuation input is transferred to an output of a surgical instrument to attempt to actuate the output opposite to the firing direction by a predetermined amount. The output is drivingly coupled with the cartridge input when the cartridge is mounted to the surgical instrument. The resulting actuation of the output is measured and compared with a threshold actuation amount. A determination is made that the cartridge is present and unfired when the resulting actuation of the output is less than the threshold actuation amount.

    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。
