Systems and methods for kinematic optimization with shared robotic degrees-of-freedom are provided. In one aspect, a robotic medical system includes a base, an adjustable arm support coupled to the base, and at least one robotic arm coupled to the adjustable arm support. The at least one robotic arm is further configured to be coupled to a medical tool that is configured to be delivered through an incision or natural orifice of a patient. The system further includes a processor configured to adjust a position of the adjustable arm support and the at least one robotic arm while maintaining a remote center of movement of the tool.

A surgical suturing tracking system configured for use with a suturing needle is disclosed. The surgical suturing tracking system comprises a spectral light emitter, a waveform sensor, and a control circuit coupled to the waveform sensor. The control circuit is configured to cause the spectral light emitter to emit spectral light waves toward a suturing needle and a tissue structure, receive an input corresponding to the spectral light waves reflected by the needle and the tissue structure and determine a distance between the needle and the tissue structure based on the received input.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. A coupling device driven by a plurality of drive disks corresponds to a first motor and a second motor. One or more processors are configured to send a low torque command to a first motor, send the low torque command to a second motor, determine whether the first motor and the second motor meet one or more hold engagement criteria, send a high torque command to the first motor in response to the first motor and the second motor meeting the one or more hold engagement criteria, and send the high torque command to the second motor in response to the first motor and the second motor meeting the one or more hold engagement criteria.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. An end effector of the surgical tool is coupled to a tool driver. An actuator is driven by a motor of the tool driver and configured to drive a degree of freedom of the end effector. One or more processors are configured to receive a position command describing a desired position for the end effector, translate the desired position to a command for a joint associated with the end effector, calculate a compensation term to compensate for a source of hysteresis for backlash and/or compliance, and send a motor command for the motor coupled with the actuator based on the compensation term and the command for the end effector.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. A tool driver is coupled to a distal end of a robotic arm and includes a roll drive disk driven by a rotary motor. One or more processors are configured to detect an attachment of a surgical tool to the tool driver. The surgical tool includes a roll tool disk to be engaged with the roll drive disk of the tool driver, actuate of the roll drive disk through the rotary motor, determine that a measured torque of the rotary motor exceeds a preset torque threshold for a preset period of time since the actuation, and report a successful engagement between the roll drive disk and the roll tool disk.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. An actuator or a motor of a tool driver is configured to operate a joint of a tool. One or more processors are configured to receive an initial joint command for the joint of the tool, determine a joint torque based on motor torque of the motor or actuator as well as motor to joint torque mapping, calculate a tip force based on an effective length associated with the joint and based on the joint torque, compare the tip force to a predetermined threshold, calculate an admittance control compensation term in response to the tip force exceeding the predetermined threshold, and generate a command for the motor or actuator based on the admittance control compensation term and the initial joint command.

A robot-assisted surgical system includes a robotic manipulator for robotic positioning of a surgical instrument, and a user input device moveable by a user to cause the robotic manipulator to move the surgical instrument. The system is configured to define virtual boundaries in a workspace of the user input device, based on range limits or user ergonomic limits of the user input device. The system alerts the user if the user input device is moved into proximity of the virtual boundary. This cues the user that it would be useful to clutch and reposition the user input device.

For kinetic sizing, the dynamic torque to be provided by a robotic system may be based off of, in part, a maximum acceleration. Rather than trying to extract maximum acceleration from many samples, a relationship of velocity to acceleration from repetitive user inputs relative to a non-surgical target in different situations (e.g., accurate, fast, or balance tracing of the target movement) is established. The velocity for any given situation may be used to estimate the acceleration from the relationship. Rather than using many trajectory samples from many users, a synthetic trajectory may be used. The synthetic trajectory may be fit to user data while maintaining high-coverage properties for direction of movement for any given pose of the robot. Alternatively, a virtual trajectory decoupled from time is used. The virtual trajectory samples the directions at any given pose in a global high-coverage manner, without specifically using a time-dependent sequence of poses.

An approach is provided for image guided procedures. The approach includes acquiring image data of at least one object of a subject, in which the acquired image data is registered to one or more coordinate systems. The approach includes receiving the acquired image data. The approach includes displaying, on one or more smartglasses, one or more superimposed images over a portion of the subject. The one or more superimposed images may be related to the acquired image data. The approach includes aligning the one or more superimposed images to correspond with a position of the at least one object.

A method for removing an implant attached to a bone during revision joint replacement surgery includes a library of implant models. A series of surface points are collected on the implant with a digitizer. A best match is computed between the collected surface points and an implant model in the library of implant models to register the position of the implant model to the implant. A location is computed of a material-implant interface based on the geometry of the implant model and the registered position of the implant model. Material is removed at the material-implant interface to separate the implant from the bone. A computer-assisted surgical system is provided for performing the method.
