Abstract: A method of manufacturing a surgical instrument includes charging a first component to a first voltage, charging a second component to a second voltage such that a pre-determined voltage differential is established between the first and second components, axially moving at least one of the first and second components relative to the other, monitoring an electrical characteristic to determine whether an axial distance between the first and second components is equal to a target axial distance, and retaining the first and second components in fixed position relative to one another once the axial distance between the first and second components is equal to the target axial distance.

Abstract: The present disclosure includes an electrosurgical generator that controls treatment energy to be provided in a coagulation mode, where the treatment energy has an adjustable voltage ramp rate which can be set to a ramp rate in a range of voltage ramp rates. The generator receives signals from an instrument over time relating to load impedance. When the load impedance is above a threshold, the generator sets the adjustable voltage ramp rate to a ramp rate in the range of voltage ramp rates, and decreases, at the adjustable voltage ramp rate, a voltage of the treatment energy. When the load impedance is below the threshold, the generator sets the adjustable voltage ramp rate to a ramp rate in the range of voltage ramp rates, and increases, at the adjustable voltage ramp rate, the voltage of the treatment energy.

Abstract: A method of treating tissue includes clamping tissue between an ultrasonic blade and a jaw member and simultaneously: transmitting ultrasonic energy to the ultrasonic blade to vibrate the ultrasonic blade at a first blade velocity thereby heating the clamped tissue; and supplying electrosurgical energy, at a constant voltage, to the jaw member and the ultrasonic blade at different potentials such that the electrosurgical energy is conducted therebetween and through the clamped tissue to heat the clamped tissue. An impedance of the clamped tissue is monitored and the simultaneous transmission of ultrasonic energy and supply of electrosurgical energy is terminated and/or a notification is output once the clamped tissue is sealed, as indicated by the impedance of the clamped tissue being equal to or greater than a threshold impedance. Surgical instruments and end effectors thereof for treating tissue in this manner are also provided.

Abstract: An electrosurgical generator includes a processor and a memory storing instructions executable by the processor. The instructions when executed, cause the generator to provide an indicated treatment energy to the instrument, where the indicated treatment energy is set by a user and having a corresponding current limit, receive signals from the instrument over time relating to a load impedance between the active electrode and the return electrode of the instrument, determine based on the signals that the active electrode and the return electrode are currently shorted together, and prior to the short, the instrument was grasping tissue between the active electrode and the return electrode, and based on the determination, reduce a current limit of treatment energy being provided to the instrument to below the corresponding current limit.

IPC: A61B18/12
Abstract: In accordance with aspects of the present disclosure, an adaptor assembly includes a plug, a selector assembly, and a connector. The plug is coupled to an electrosurgical generator and is configured to receive electrosurgical energy from the electrosurgical generator. The selector assembly includes a first position and a second position. The first position is configured to indicate a first setting of the electrosurgical generator. The second position is configured to indicate a second setting of the electrosurgical generator. The selector assembly, when actuated, indicates the selected position to the electrosurgical generator to initiate the corresponding setting. The connector is configured to couple to a surgical instrument and convey the electrosurgical energy to the surgical instrument. The electrosurgical energy, when based on the first setting, is different from the electrosurgical energy, when based on the second setting.

Abstract: An ablation probe is provided. The ablation probe includes a housing that is configured to couple to a microwave energy source. A shaft extends distally from the housing and includes a radiating section at a distal end thereof. A sensor assembly is operably disposed on the housing and includes a pair of sensor contacts. One or more sensors are positioned adjacent the radiating section and extend along the shaft. The sensor(s) have a pair of sensor contact pads that are positioned on the shaft for contact with the pair of sensors such that during transmission of microwave from the radiating section into target tissue at least one electrical parameter is induced into the at least one sensor and detected by the pair of sensor contacts.
