A Self-Limiting Electrosurgical Return Electrode

摘要

A self-limiting electrosurgical return electrode includes a semi-insulating member for limiting the density of electrosurgical current flowing through the electrode to less than a predetermined level to prevent a patient burn and a conductor member coupled to the semi-insulating member, the conductor member having a split plate configuration and coupleable to circuitry for monitoring the contact area between the electrode and a patient.
