A surgical instrument comprising a shaft, an end effector, a housing, a drive assembly, and a manually-driven actuator is disclosed. The end effector comprises a first jaw and a second jaw rotatable relative to the first jaw between an open position and a clamped position. The housing comprises a rotary input movable by a motor. The drive assembly is operably engaged with the rotary input. The drive assembly is movable by the motor in a motorized mode of operation to transition the second jaw toward the clamped position. The drive assembly is movable in a non-motorized mode of operation by the manually-driven actuator to permit a transition of the second jaw toward the open position to release tissue between the first jaw and the second jaw.

Various surgical systems are disclosed. A surgical system can include a surgical robot and a surgical hub. The surgical robot can include a control unit in signal communication with a control console and a robotic tool. The surgical hub can include a display. The surgical hub can be in signal communication with the control unit. A facility can include a plurality of surgical hubs that communicate data from the surgical robots to a primary server. To alleviate bandwidth competition among the surgical hubs, the surgical hubs can include prioritization protocols for collecting, storing, and/or communicating data to the primary server.

A generator, ultrasonic device, and method for controlling a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency. The control circuit controls the temperature of the ultrasonic blade based on the inferred temperature.

A surgical instrument comprising a staple cartridge and at least two independent antenna arrays configured to communicate with the staple cartridge.

Methods and systems for determining and mapping a location of a distal end region of an elongate shaft. An illustrative method may comprise obtaining data from an accelerometer located in the elongate shaft adjacent a distal end thereof, determining a length of the elongate shaft inserted into a body from a reference point, merging the accelerometer data and the length of the elongate shaft to localize the distal end region of the elongate shaft, reconstructing a line of travel of the medical device within the body, and superimposing the reconstructed line of travel over an image of an anatomy of the patient.

An apparatus for mixing bone cement for use in orthopedic surgeries includes a mixing region and an agitator for mixing the cement ingredients. The apparatus can be operated or acted on by a power tool for the mixing of the bone cement. The agitator may act as a generator to charge embedded electronics of the apparatus such as with a magnet in the agitator that interacts with a wire coil outside of the agitator. A timer of the apparatus may be started by a sensor of the apparatus, in response to a mechanical torque value, or by a magnetic sensor that can sense a start state of the apparatus. When the timer is complete, a cue by the apparatus signals to the user that the mixed cement is ready and able to be applied.

Relatively non-invasive devices and methods for heating or cooling a patient's body are disclosed. Devices and methods for treating ischemic conditions by inducing therapeutic hypothermia are disclosed. Devices and methods for inducing therapeutic hypothermia through esophageal cooling are disclosed. Devices and methods for operative temperature management are disclosed.

Aspects of embodiments pertain to an intraoperative ophthalmic tissue monitoring system, comprising at least one sensor configured to sense a physical quantity relating to an ophthalmic tissue characteristic of an eye. The system is further configured to provide, responsive to sensing the physical quantity, a sensor output relating to the sensed physical quantity. The system additionally comprises a processor, and a memory comprising for storing software executable by the processor for enabling the following: controlling, based on the sensor output, a characteristic of ultrasound energy for performing phacoemulsification of a lens of the eye.

A surgical end effector includes a cartridge. The cartridge includes first and second sensor arrays disposed in the cartridge. The first sensor array is configured to sense a function of a first component located within the cartridge and the second sensor array is configured to sense a function of a second component located within the cartridge. The first and second sensor arrays are electrically coupled to an electronic circuit. The electronic circuit includes a control circuit configured to receive signal samples from the first sensor array, receive signal samples from the second sensor array, and process the signals samples received from the first and second sensor arrays to determine a status of the cartridge.

A medical instrument includes a first device (108) including shape-sensed flexible instrument, a second device (102) disposed over the first device and a third device (109) disposed over the first device and a portion of the second device. The second and third devices include a geometric relationship such that a position of the second device and the third device is determined from shape sensing information of the first device and the geometric relationship.
