Abstract
An electrosurgical flux supply unit includes a first terminal configured to deliver a first electrical flux, the first terminal being configured to be electrically coupled with a first electrode of a first electrosurgical instrument, a second terminal configured to receive a second electrical flux; the second terminal being configured to be electrically coupled with a second electrode of the first electrosurgical instrument, and an electrical switching mechanism selectively configurable between a first state and a second state. In the first state, the electrical switching mechanism electrically couples the first electrode with the first terminal and, in the second state, the electrical switching mechanism electrically isolates the first electrode from the first terminal. The electrosurgical flux supply unit is configured to maintain the electrical coupling of the second terminal with the second electrode in both the first state and the second state of the electrical switching mechanism.
