A method for controlling a user interface of a modular energy system. The modular energy system comprises a header module and a display screen on which the user interface is displayed. The modular energy system can detect attachment of a first module thereto, control the user interface to display one or more first user interface elements corresponding to the first module, detect attachment of a second module to the modular energy system, control the user interface to resize the one or more first user interface elements to accommodate display of one or more second user interface elements corresponding to the second module, and control the user interface to display the one or more second user interface elements. The various UI elements can correspond to the particular module type that is being connected to the modular energy system.

A method of operating a modular surgical system including a control module, a first surgical module, and a second surgical module is disclosed. The method includes detachably connecting the first surgical module to the control module by stacking the first surgical module with the control module in a stack configuration, detachably connecting the second surgical module to the first surgical module by stacking the second surgical module with the control module and the first surgical module in the stack configuration, powering up the modular surgical system, and monitoring distribution of power from a power supply of the control module to the first surgical module and the second surgical module.

A surgical instrument includes a housing, a shaft extending from the housing, an end effector assembly extending from the shaft and configured to rotate and/or articulate relative to the housing, a motor disposed within the housing and operably coupled to the end effector assembly to rotate and/or articulate of the end effector assembly relative to the housing, and a sensing assembly configured to sense movement of the housing relative to a reference position and to drive the motor to rotate and/or articulate of the end effector assembly relative to the housing based upon the sensed movement. The sensing assembly is configured to operate in each of a standard mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in a similar direction, and a reversed mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in an opposite direction.

An ultrasonic transducer assembly of an ultrasonic surgical instrument includes a piezoelectric stack, an ultrasonic horn secured to and extending distally from the piezoelectric stack and including a body and a nose extending distally from the body, an overmold seal formed about the body of the ultrasonic horn, and a casing disposed about the piezoelectric stack, the body of the ultrasonic horn, and the overmold seal. The casing defines a distal opening through which the nose of the ultrasonic horn extends. The overmold seal establishes a hermetic seal with the casing to define a hermetically sealed interior enclosing the piezoelectric stack and the body of the ultrasonic horn therein.

Various surgical systems are disclosed. A surgical system comprises a robotic tool, a robot control system, a surgical instrument, and a surgical hub. The robot control system comprises a control console and a control unit in signal communication with the control console and the robotic tool. The surgical hub comprises a display. The surgical hub is in signal communication with the robot control system. The surgical hub is configured to detect the surgical instrument and represent the surgical instrument on the display.

A surgical instrument is disclosed. The surgical instrument comprises an end effector comprising an ultrasonic blade and a clamp arm. The clamp arm is movable relative to the ultrasonic blade to transition the end effector between an open configuration and a closed configuration to clamp tissue between the ultrasonic blade and the clamp arm. The surgical instrument further comprises an ultrasonic transducer configured to generate an ultrasonic energy output and a waveguide configured to transmit the ultrasonic energy output to the ultrasonic blade. The surgical instrument further comprises a control circuit, configured to detect an immersion of the end effector in a liquid and compensate for heat flux lost due to the immersion of the end effector in the liquid.

An end effector assembly of a surgical system includes a blade and a jaw member movable relative to the blade between a spaced-apart position and an approximated position for clamping tissue. The blade defines a first width and the jaw member defines a second width wider than the first width. The jaw member defines a first side facing the blade and a second side facing away from the blade. A marking is formed on the second side of the jaw member facing away from the blade. The marking defines a third width substantially equal to the first width of the blade to allow a surgeon to visualize a width of the blade when the blade is not visible.

A method of controlling the temperature of an ultrasonic blade includes applying a power level to an ultrasonic transducer to achieve a desired temperature at an ultrasonic blade coupled to the transducer via an ultrasonic waveguide, inferring a temperature of the blade based on a voltage V.sub.g(t) signal and a current I.sub.g(t) signal applied to the transducer, comparing the inferred temperature of the blade to a predetermined temperature; and adjusting the power level to the transducer based on the comparison. In some aspects, the method includes measuring a phase angle φ between the voltage V.sub.g(t) and the current I.sub.g(t) and inferring the temperature of the blade from the phase angle φ. In some aspects, the method includes measuring an impedance Z.sub.g(t) equal to a ratio of the voltage V.sub.g(t) to the current I.sub.g(t) and inferring the temperature of the blade from the impedance Z.sub.g(t).

A method for adjusting the operation of a surgical suturing instrument using machine learning in a surgical suite is disclosed. The method comprises gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical suturing instrument comprising a suturing needle configured to be mechanically advanced through a suturing stroke, analyzing the gathered data to determine an appropriate operational adjustment of the surgical suturing instrument, and adjusting the operation of the surgical suturing instrument to improve the operation of the surgical suturing instrument.

An ultrasonic surgical instrument comprises a cylindrical shaft and a blade at a distal or free end of the shaft, the blade being unitary and continuous with the shaft, without an intervening joint. The shaft has a longitudinal axis and the blade includes a flat or planar blade body with a proximal end eccentrically disposed relative to the shaft axis. Thus, the blade body or at least a proximal end portion thereof is disposed eccentrically relative to the shaft. The blade in its entirely may be inclined relative to the shaft axis or extend parallel thereto.
