Abstract
Aspects of the present disclosure are presented for managing simultaneous outputs of surgical instruments. In some aspects, methods are presented for synchronizing the current frequencies. In some aspects, methods are presented for conducting duty cycling of energy outputs of two or more instruments. In some aspects, systems are presented for managing simultaneous monopolar outputs of two or more instruments, including providing a return pad that properly handles both monopolar outputs in some cases.
Claims20
A method of a surgical system for providing simultaneous activation of a first electrosurgical unit and a second electrosurgical unit on a patient, the method comprising:
- generating, by the surgical system, a first energy output having a first frequency from the first electrosurgical unit;
- simultaneously, generating, by the surgical system, a second energy output having a second frequency from the second electrosurgical unit;
- wherein the second frequency is different than the first frequency;
- measuring, by the surgical system, a magnitude of impedance arising from the simultaneous generation of the first energy output and the second energy output, wherein the magnitude of impedance is proportional to the difference in frequency between the second frequency and the first frequency;
- determining that the magnitude of the impedance exceeds a predetermined threshold;
- and
- based on the determination, performing an adjustment to correct for the impedance exceeding the predetermined threshold.
An electrosurgical system comprising:
- a first electrosurgical unit configured to generate a first energy output having a first frequency;
- a second electrosurgical unit configured to generate a second energy output having a second frequency different from the first frequency;
- a control circuit communicatively coupled to the first electrosurgical unit and the second electrosurgical unit, and configured to:
- measure a magnitude of impedance arising from the simultaneous generation of the first energy output and the second energy output, wherein the magnitude of impedance is proportional to the difference in frequency between the second frequency and the first frequency;
- determine that the magnitude of the impedance exceeds a predetermined threshold;
- and
- based on the determination, perform an adjustment to correct for the impedance exceeding the predetermined threshold.
