An input control device is disclosed. The input control device can be configured to operate in different modes depending on proximity data provided by a proximity detection system. The input control device can include a feedback generator configured to generate feedback in response to the input control device switching between operational modes, the proximity data provided by the proximity detection system, and/or other conditions of the surgical procedure, robotic surgical tool, surgical site, and/or patient. The input control device can include a variable resistance assembly for resisting input control motions applied to an actuator thereof. Additionally or alternatively, the input control device can include an end effector actuator assembly for repositioning the end effector actuator based on feedback from a paired robotic surgical tool.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. One example method includes providing a redundant degree of freedom (DoF) for an end effector joint of one DoF by driving the joint with two actuators, calculating a position displacement of the joint to effect a desired end effector movement in response to an input command, calculating a first movement of the two actuators based on the position displacement of the joint and a second movement of the two actuators based on a second control objective in a null space corresponding to the redundant DoF, and driving the joint according to the first movement and the second movement to effect the desired end effector movement while accomplishing the second control objective in the null space.

A surgical instrument drive system is configured to actuate functions of a surgical end effector. The surgical instrument drive system includes a first rotary input drive gear configured to be driven by a corresponding first rotary output drive gear of a surgical robot interface; a second rotary input drive gear configured to be driven by a corresponding second rotary output drive gear of a surgical robot interface; and a shifter.

A method for generating and updating a three-dimensional representation of a surgical site based on imaging data from an imaging system is disclosed. The method comprises the steps of generating a first image of the surgical site based on structured electromagnetic radiation emitted from the imaging system, receiving a second image of the surgical site, aligning the first image and the second image, generating a three-dimensional representation of the surgical site based on the first image and the second image as aligned, displaying the three-dimensional representation on a display screen, receiving a user selection to manipulate the three-dimensional representation, and updating the three-dimensional representation as displayed on the display screen from a first state to a second state according to the received user selection.

Methods and systems for detecting, monitoring, and accounting for anatomical motion is provided. An initial contact between a first robotic arm and an anatomical element of a patient may be detected based on information received from at least one internal sensor of the first robotic arm. A position of the anatomical element may be determined based on the information. The determined position may be compared to an expected position of the anatomical element. A tool trajectory of a second robotic arm may be updated when the determined position is offset from the expected position.

One embodiment relates to a handheld surgical instrument that comprises a rotary surgical end effector and a coupler configured to cause rotation of the same. The handheld surgical instrument further comprises a motor, which is configured to drive a motor output region. The handheld surgical instrument further comprises a transmission, which defines a transmission input region that interfaces with the motor output region and a transmission output region coupled to the transmission input region. The transmission output region is operably coupled to the coupler, and the transmission is configured to alter the speed of the coupler relative to the motor output region. The motor output region and the transmission input region interface one another at a motor-transmission interface, and the motor-transmission interface comprises a motor-transmission backlash such that drive of the motor output region within the motor-transmission backlash does not cause rotation of the rotary surgical end effector.

A surgical hub for prioritizing data on a display using situational awareness of a medical instrument may be provided. A first surgical task that uses a medical instrument during a medical procedure may be determined based on a contextual data. A second surgical task that uses the medical instrument may be determined based on the first surgical task and the contextual data. A message may be sent that may instruct a display to prioritize a display data associated with the second surgical task.

Methods and systems of placing a medical fastener at a predetermined depth in a bone are described. A surgical tool can include an attachment assembly configured to interchangeably engage a medical fastener and a cutting element or bone removal tool and a drive assembly coupled to the attachment assembly. The attachment assembly can be configured to automatically release the medical fastener in response to the drive assembly reaching its end or distal-most position to place the medical fastener at a predetermined depth within the bone.

A portable neck strength testing device includes a support member securable to the body of a subject, a measurement unit coupled to the support member and a head mount adjustably connected to the measurement unit. The head mount includes a first portion configured to engage the head of the subject and the head mount is displaceable in response to motion of the first portion. The measurement unit is configured to detect displacement of the head mount and measure therefrom at least a force or a torque exerted on the head mount.

A computer-assisted system comprises a manipulator configured to support a tool, a lockable joint, and a controller. The manipulator extends distally from a base and comprises a distal portion. The lockable joint is coupled to the base and located proximally relative to the base. The controller is operably coupled to a powered joint. The powered joint is located distally relative to the base. The controller is configured to perform operations. The operations comprise: driving the powered joint to move the distal portion while the lockable joint is locked, and driving the powered joint to move the base while the lockable joint is unlocked and a position of the distal portion is externally maintained. A method includes processes for operating a computer-assisted system. A method includes determining a desired motion envelope for a tool supported by a manipulator, and positioning a base of the manipulator based on the desired motion envelope.
