摘要:
A method for performing an electrosurgical procedure at a surgical site on a patient, the method including the steps of providing a current restricting circuit operatively coupled between a source of electro surgical energy and an electrode, the current restricting circuit including: a switch configured to direct the flow of electrosurgical energy; and a plurality of current restrictive devices arranged in an H-Bridge arrangement, wherein the switch is disposed between adjacent current restrictive devices of the plurality of current restrictive devices; restricting the flow of electrosurgical energy wherein the current restricting circuit is configured to restrict a flow of electrosurgical energy when the switch is in a first position; enabling the flow of electrosurgical energy when the switch is in a second position; and dynamically controlling the electrosurgical energy delivered to the electrode with the current restricting circuit.
