The present invention provides, in various embodiments, systems and methods for robotic manipulation of a patient's anatomy, such as the uterus, during surgical procedures.

A robotic system includes a robotic manipulator configured to: manipulate a medical instrument having a basket; open the basket at a first opening speed and a second, faster opening speed; and close the basket at a first closing speed and a second, faster closing speed. The system includes an input device configured to receive one or more user interactions and initiate one or more actions by the robotic manipulator, including directly controlled movement and/or pre-programmed motions. Control circuitry of the robotic system is configured to: in response to receiving a first user interaction via the input device, trigger a first pre-programmed motion of the robotic manipulator to open the basket at the second, faster opening speed; and in response to receiving a second user interaction via the input device, trigger a second pre-programmed motion to close the basket at the second, faster closing speed.

Disclosed are devices and methods for creating a bore in bone. The devices and methods described involve driving a rotating bit in an axial direction such that both rotation and linear movement are controlled and measurable. The instrument is useful for a surgeon to control and simultaneously measure the travel of the tool into the bone and prevent injury to surrounding structures.

Various torque-limiting surgical driver devices, systems, and methods are disclosed. The surgical driver can include a body, a motor that is configured to rotate a drill bit engaged with the surgical driver, and a processor configured to control operation of the surgical driver. The surgical driver can have torque-limiting functionality, such as by monitoring the amount of torque applied to a drill bit and reducing or stopping rotation of the drill bit when certain torque-limiting criteria are met.

This application relates to a method of mitigating a collision of a slave robot for surgery. In one aspect, the method includes obtaining an external torque generated when the slave robot collides with another object or a person and obtaining a joint angle of the slave robot. The method may also include calculating a target joint angle for changing a position of the slave robot based on the obtained external torque and the obtained joint angle, such that the external torque is attenuated. The method may further include controlling the slave robot to change the position thereof from the obtained joint angle to the calculated target joint angle.

Apparatus for measuring a torque, consisting of a probe having a shaft with a shaft distal end. The probe has a distal end assembly, configured to be inserted into an organ of a human subject, and having a distal termination and a proximal termination connected to the shaft distal end. A position sensor assembly is attached to the distal end assembly in proximity to the distal termination, the position sensor assembly being configured to provide signals indicative of a three-dimensional position and orientation of the distal termination with respect to the shaft distal end. A processor is configured to compute a torsion of the distal termination with respect to the proximal termination in response to the signals from the position sensor assembly, and compute the torque on the distal end assembly in response to the torsion and a predetermined correspondence between the torsion and the torque.

A rotary torque releaseor for orthopedic surgery includes an output anvil and a hammer that is capable of imparting linear and rotary force on the anvil. The anvil may be moveable on a leadscrew element to alternately generate energy in an energy storage means and to move along the leadscrew element to torque release the anvil. A viscoelastic mechanism or a dampening mechanism is used to reduce the reflected force and or torque during operation of the rotary torque releaseor. High frequency axial movements by the torque releaseor obviate the need for a surgeon to provide an external push force on the torque releaseor in order to perform a successful surgical operation.

A method for downloading data from a surgical hub to a surgical instrument is disclosed. The method comprises assembling a first shaft assembly to a handle and downloading a first set of operational data from the surgical hub to the handle once the first shaft assembly is attached to the handle. The method further comprises assembling a second shaft assembly to the handle and downloading a second set of operational data from the surgical hub to the handle once the second shaft assembly is attached to the handle, wherein the second set of operational data is different than the first set of operational data.

A surgical robotic arm includes a first link; a second link coupled to the first link at a first joint such that at least one of the first link or the second link is movable relative to each other; and a first actuator configured to move at least one of the first link or the second link. The surgical robotic arm also includes a joint torque sensor disposed within the first joint and configured to measure torque imparted on at least one of the first link or the second link to obtain a measured torque value. The surgical robotic arm further includes a controller configured to: determine an estimated joint torque value; compare the estimated joint torque value to the measured torque value; and determine an environmental torque value based on a comparison of the estimated joint torque value and the measured torque value.

A return pad of an electrosurgical system is disclosed. The return pad includes a plurality of conductive members and a plurality of sensing devices. The conductive members are configured to receive radio frequency current applied to a patient. The sensing devices are configured to detect at least one of the following: a nerve control signal applied to the patient; and a movement of an anatomical feature of the patient resulting from application of the nerve control signal.
