Abstract: A computer-assisted device include an actuator and one or more processors. The computer-assisted device is configured to support an instrument having an end effector located at a distal end. To perform an operation with the instrument, the one or more processors are configured to operate the end effector according to a state machine having a first state and a second state. In the first state a velocity set point of the actuator is set to a first velocity. In the second state the velocity set point of the actuator is set to a second velocity lower than the first velocity. The state machine transitions from the first state to the second state when a force or torque applied by the actuator is above a first threshold and transitions from the second state to the first state when the force or torque applied by the actuator is below a second threshold.

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 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 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: Surgical devices, systems, and related methods provide automated assessment of the status of a surgical instrument. A surgical device is configured to staple tissue via a replaceable stapler cartridge. The surgical device includes a pusher member configured to articulate the stapler cartridge to deploy staples. The surgical device includes an actuation mechanism that articulates the pusher member and a control unit configured to control operation of the actuation mechanism to attempt move the pusher member from a first position to a second position subject to an output limit for the actuation mechanism and determine an attribute of the stapler cartridge based on an amount of movement of the pusher member achieved. The determined attribute can indicate a type of the stapler cartridge selected from different stapler cartridges, whether the stapler cartridge has already been fired, or that no stapler cartridge is mounted to the surgical device.

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.
