Patent ID: 11648046

Abstract:
An electrode assembly for use with an electrosurgical instrument includes a base portion, a return lead adapted to be electrically coupled to a return terminal of an electrosurgical generator, an electrical insulator supported on a distal portion of the return lead, a tensioning mechanism, and an active lead adapted to be electrically coupled to an active terminal of the electrosurgical generator. The tensioning mechanism includes a slider slidably disposed in the base portion, a rotation rod threadably coupled to the slider, and a spring proximally biasing the slider. The active lead having a first end portion securely fixed to the base portion and a second end portion slidably coupled to the rotation rod of the tensioning mechanism. A portion of the active lead extends around the electrical insulator. Rotation of the rotation rod causes axial displacement of the second end portion of the active lead to tension the active lead about the electrical insulator.
