Surgical instrument utilizing drive signal to power secondary function
A surgical instrument connectable to a surgical energy module that is configured to provide a first drive signal at a first frequency range for driving a first energy modality and a second drive signal at a second frequency range for driving a second energy modality is provided. The surgical instrument can comprise a surgical instrument component configured to receive power from a direct current (DC) power source, an end effector, and a circuit. The circuit can be configured to convert the first electrical signal to a DC voltage, apply the DC voltage to the surgical instrument component, and deliver the second energy modality to the end effector according to the second drive signal. Alternatively, the circuit can be disposed within a cable assembly configured to connect the surgical instrument to the surgical energy module.
Consolidated user interface for modular energy system
A modular energy system including a header module configured to removably connect to an energy module. The energy module can comprise a port configured to deliver one or more energy modalities to a surgical instrument connected thereto. The header module can comprise a display screen configured to display a user interface. The header module can further include a control circuit configured to detect attachment of energy modules to the modular energy system and control the display of the user interface to display UI portions for each connected module and reconfigure the displayed UI portions to accommodate the new UI portions as additional energy modules are connected to the modular energy system.
IRREVERSIBLE ELECTROPORATION AND THERMAL ABLATION BY FOCAL CATHETER
Examples presented herein generally include a catheter and a system configured to deliver electrical pulses for ablation by IRE and methods for constructing and using the same. The catheter and system can further be configured to delivery RF electrical current for thermal ablation interleaved with ablation by IRE, simultaneously with ablation by IRE, and/or separately from ablation by IRE. The catheter can have a linear distal portion with a tip electrode, a middle ring electrode, and a proximal ring electrode. The electrodes be configured in several combinations to provide unipolar ablation, bipolar ablation, and/or a combination thereof.
POWERED SURGICAL INSTRUMENT WITH INDEPENDENT SELECTIVELY APPLIED ROTARY AND LINEAR DRIVETRAINS
An apparatus includes a body and a shaft assembly. The body includes a rotary drive output, a linear drive output, and a control module. The shaft assembly includes a distal end and a proximal end. The distal end includes a type of end effector configured to operate on tissue. The proximal end is configured to removably couple with the body assembly. The proximal end includes one or both of a rotary drive input configured to couple with the rotary drive output or a linear drive input configured to couple with the linear drive input. The shaft assembly is configured to actuate the end effector in response to movement of one or both of the rotary drive input or the linear drive input.

Robotic surgical pedal with integrated foot sensor
A foot pedal assembly for controlling a robotic surgical system. The foot pedal assembly including a foot pedal base, a foot pedal and a sensor. The foot pedal moves relative to the foot pedal base and has a contact surface extending from a distal end to a proximal end of the foot pedal. The contact surface is to come into contact with a foot of a user during use of the foot pedal assembly for controlling the robotic surgical system and the distal end is farther away from a heel of the foot than the proximal end during use of the assembly for controlling the robotic surgical system. The sensor is coupled to the contact surface of the foot pedal at a position closer to the proximal end than the distal end, and the sensor is operable to sense a target object positioned a distance over the contact surface.
Connector to couple surgical instrument with navigation system
A surgical instrument assembly includes a surgical instrument having an instrument body, an elongate member with a distal end configured to be inserted into an anatomical passageway of a patient, a sensor operable to generate a signal corresponding to a location of the elongate member, and a first electrical connector electrically coupled with the sensor. The assembly further includes a cable assembly having a cable that communicates with a processor, and a coupling that releasably couples with the instrument body. The coupling includes a coupling body having first and second lateral sides that extend parallel to one another and are configured to extend parallel to a side of the instrument body when the coupling is coupled with the instrument body. The coupling includes a second electrical connector that electrically couples with the first electrical connector to transmit the signal from the sensor proximally through the cable and toward the processor.

An apparatus includes a flexible electrically-insulating substrate including an inner surface and an outer surface. The substrate is shaped to define multiple channels passing between the inner surface and the outer surface, at least some of the channels being concave channels. The apparatus further includes an outer layer of an electrically-conducting metal covering at least part of the outer surface, an inner layer of the electrically-conducting metal covering at least part of the inner surface, and respective columns of the electrically-conducting metal that fill the channels such as to connect the outer layer to the inner layer.
Robotic surgical system with safety and cooperative sensing control
A system for controlling a robotic end-effector is disclosed. The system includes a robotic arm, a surgical tool including an end-effector with articulatable arm and a clamp jaw. A tool driver is coupled to the surgical tool and a motor is coupled to the tool driver and is configured to drive the surgical tool. A sensor is configured to sense external forces applied to the end-effector. A central control circuit is configured to control the tool driver. The central control circuit is configured to receive a sensed parameter from the sensor, receive a sensed motor current (I) from the motor, and control the tool driver based on the sensed parameter and the motor current (I).
Systems and methods for selecting, activating, or selecting and activating transducers
Transducer-based systems can be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Selection of a plurality of graphical elements and/or between graphical elements can cause visual display of a corresponding activation path in the graphical representation. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.
Secure cryosurgical treatment system
A method for cryogenically treating tissue. A connection is detected between a probe having a disposable secure processor (DSP) to a handpiece having a master control unit (MCU) and a handpiece secure processor (HSP), the probe having at least one cryogenic treatment applicator. The probe is fluidly coupled to a closed coolant supply system within the handpiece via the connection. An authentication process is initiated between the DSP and the HSP using the MCU. As a result of the authentication process, one of at least two predetermined results is determined, the at least two predetermined results being that the probe is authorized and non-authorized.
