    Abstract: A medical device system can include a surgical tool, and a one-way input, and a drive system operatively coupled to the surgical tool and the oneway input device. The drive system can be rotatable in a first direction to effectuate a first operation of the surgical tool, and rotatable in a second direction to effectuate a second the operation of the surgical tool. The one-way input device can be operable to rotate the rotatable drive system in the second direction but not the first direction.

    Abstract: A medical device can include a housing, a first seal structure, and a seal expander. The first seal structure can have a proximal end and a distal end, and a side wall surrounding and defining an interior chamber. A seal wall can be connected to the side wall and include an expandable opening. A seal expander can be coupled to the housing, and can be at least partially in the interior chamber of the first seal structure. The seal expander can include an expandable neck portion and a seal interface portion, the seal interface portion being near an intersection of the side wall and the seal wall.

    Abstract: A surgical instrument is provided that includes a first jaw having a first jaw axis and that includes a proximal portion pivotally mounted to the base to be pivotable about a pivot axis between an open and a closed positions and including a distal portion; a second jaw having a second jaw axis and including a proximal portion secured to the base and including a distal portion; a first side edge secured to the first jaw a second side edge secured to the second jaw; a third side edge secured to the first jaw; a drive member including a cross-beam, which is sized to slideably engage the first, second and third side edges, a first transverse beam portion, and a second transverse beam portion; and a lead screw configured to advance the drive member in a distal direction parallel to the second jaw axis while engaging one or the other of the first and second side edges and the second side edge.

    Abstract: A knife member that can have a blade portion configured operation within a surgical stapling device. A first frame portion can extend from the blade portion to a first connection portion. A second frame portion can extend from the first frame portion to a second connection portion. At least one of the first and second frame portions can include a fused portion. The fused portion can be configured to fail when a predetermined amount of force is applied to the fused portion.

    Abstract: A system and method of variable velocity control of a surgical instrument in a computer-assisted medical device including an end effector located at a distal end of the instrument, an actuator, and drive mechanisms for coupling force or torque from the actuator to the end effector. To perform an operation with the instrument, the computer-assisted medical device sets a velocity set point of the actuator to an initial velocity, monitors force or torque applied by the actuator, reduces the velocity set point when the applied force or torque is above a first threshold, increases the velocity set point when the applied force or torque is below a second threshold, decreases the velocity set point to zero when the applied force or torque is above a maximum threshold, and drives the actuator based on the velocity set point. The first and second thresholds are lower than the maximum threshold.

    Abstract: A medical device drive system including a lever body having portions defining a lever body cavity, a nut housing in the lever body cavity, and a first nut at least partially in the first nut cavity. The first nut is slideable in the first nut cavity between an engaged position in which the lead screw interface is engaged with the engagement portion of the lead screw, and a disengaged position in which the lead screw interface is not engaged with the engagement portion of the lead screw. The lead screw interface of the first nut is selectively engageable with the engagement portion of the lead screw by sliding the lever body and pin relative to the first nut housing.
