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: Surgical tools having a two degree-of-freedom wrist, wrist articulation by linked tension members, mechanisms for transmitting torque through an angle, and minimally invasive surgical tools incorporating these features are disclosed. An elongate intermediate wrist member is pivotally coupled with a distal end of an instrument shaft so as to rotate about a first axis transverse to the shaft, and an end effector body is pivotally coupled with the intermediate member so as to rotate about a second axis that is transverse to the first axis. Linked tension members interact with attachment features to articulate the wrist. A torque-transmitting mechanism includes a coupling member, coupling pins, a drive shaft, and a driven shaft. The drive shaft is coupled with the driven shaft so as to control the relative orientations of the drive shaft, the coupling member, and the driven shaft.

Abstract: A surgical system includes a dynamic preload tension feature for a tensioning element that actuates a distal end comport 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: 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 cartridge of a surgical instrument includes a housing, a lead screw mounted for rotation in the housing, a drive member operatively coupled with the lead screw, and a knife member. The knife member is driven distally by the drive member and is configured to cut when moved distally. During an initial distal movement of the drive member, the knife member is coupled with the housing to restrain the knife member from moving distally. Subsequent to the initial distal movement of the drive member, the drive member drives the knife member toward the distal end.

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.
