Abstract: A powered surgical instrument is disclosed comprising a motor, a shaft extending from the housing, an end effector extending from the shaft, a power source, a processor, a motor controller, and a control circuit. The control circuit comprises a first segment configured to supply the processor with a first voltage from the power source, and a second segment configured to supply the motor controller with a second voltage from the power source. The second voltage is different than the first voltage. The powered surgical instrument further comprises means for shifting power to the first segment when the second segment experiences a power drop due to high power demand from the motor.

Abstract: Various embodiments of tool assemblies are provided having at least one rotary input coupling and at least one linear input coupling for allowing either a rotary output or a linear output (e.g., from a tool driver on a surgical robot) to activate at least one mechanism of the tool assembly. For example, mechanisms of the tool assembly can include a clamping assembly, a firing assembly, an articulation assembly, and a roll assembly. The clamping assembly can open and close jaws of an end effector, the firing assembly can translate a knife assembly through the end effector to fire staples and cut tissue, the articulation assembly can articulate the end effector, and the roll assembly can rotate the elongate shaft and/or the end effector.

Abstract: Surgical instruments and control systems therefor are disclosed. A surgical instrument can comprise: a power circuit comprising a power source and a switch, a microcontroller coupled to the power circuit, a handle comprising an attachment portion, and a control circuit in signal communication with the microcontroller. The attachment portion can comprise a first electrical contact in signal communication with the microcontroller. The control circuit can comprise a sensor configured to detect an attachment state of the attachment portion. The control circuit can communicate the detected attachment state to the microcontroller, and the microcontroller can ignore signals from the first electrical contact when the control circuit communicates a detached state. The attachment portion can comprise a second electrical contact coupled to a second power circuit, and the second power circuit can decouple the second electrical contact and the second power source when the sensor detects the detached state.

Abstract: A robotic surgical tool is disclosed. The robotic surgical tool can comprise an end effector comprising a firing member; a drive system responsive to a motor-driven input; and a proximal housing comprising a retraction mechanism. The retraction mechanism can comprise a control responsive to a manual input. The control can be rotatable in a first direction through a retraction motion and rotatable in a second direction through a reset motion. The retraction mechanism can further comprise a clutch coupled to the control. The clutch can be configured to drivingly engage the drive system as the control rotates through the retraction motion to supply a proximal retraction stroke to a firing bar and drivingly disengaged from the drive system as the control rotates through the reset motion to prevent any displacement of the firing bar by the retraction mechanism until the control is reset for a subsequent retraction motion.

Abstract: An apparatus includes a body, a shaft, a stapling head assembly, and an anvil. The body includes a motor, a first user input feature, and a second user input feature. The first user input feature is operable to activate the motor. The shaft extends distally from the body. The stapling head assembly is positioned at a distal end of the shaft. The stapling head assembly includes an anvil coupling feature, at least one annular array of staples, and a staple driver. The second user input feature is operable to drive the anvil coupling feature longitudinally. The staple driver is operable to drive the at least one annular array of staples. The motor is operable to drive the staple driver. The anvil is configured to couple with the anvil coupling feature. The anvil is further configured to deform the staples driven by the staple driver.

Abstract: A surgical tool includes a drive housing, a closure tube that extends from the drive housing, an end effector arranged at an end of the closure tube and having opposing jaws, and a closure yoke mounted to the closure tube and having a projection extending therefrom. A gearing assembly includes one or more spur gears attached to a corresponding one or more drive shafts such that rotation of the one or more drive shafts correspondingly rotates the one or more spur gears, and a closure cam gear positioned to intermesh with the one or more spur gears and defining a profile that receives the projection. Rotating the one or more spur gears causes the closure cam gear to rotate, which causes the projection to traverse the profile, and the projection traversing the profile urges the closure yoke and the closure tube to linearly displace and thereby actuate the jaws.

Abstract: A robotic surgical system that comprises a closure system. The closure system comprises a first pinion drivingly coupled to a first motor, a second pinion drivingly coupled to a second motor, and a closure gear selectively driven by the first pinion and the second pinion. The robotic surgical system further comprises a control circuit configured to implement a motor crosscheck operation. The control circuit is configured to receive a first parameter indicative of a first torque generated by the first motor, receive a second parameter indicative of a second torque generated by the second motor, compare the first parameter to the second parameter, and transmit a signal to a communication device, wherein the signal is based on the comparison and indicative of a status of the closure system.

Abstract: A robotic surgical system includes a robotic arm, a surgical device coupled with the robotic arm and configured to extend through a body wall of a patient, and a controller in communication with the robotic arm. The controller is configured to determine a position of the surgical device relative to the patient. The controller is also configured to acknowledge a maximum allowable metric associated with the body wall at the determined position, and determine a metric associated with the body wall at the determined position. The controller is furthermore configured to drive the robotic arm to manipulate the surgical device such that the determined metric does not exceed the maximum allowable metric.

Abstract: A surgical instrument for use by an operator in a surgical procedure includes an elongate shaft, an end effector extending from the elongate shaft, and a control system. The end effector is articulatable relative to the elongate shaft between a home state position and an articulated position. The control system includes a processor and a memory coupled to the processor to store program instructions. The processor can alert the operator when the end effector reaches the home state position from the articulated position.
