Abstract
An electrosurgical device having an electrode and an insulating piece such as a ceramic insulator is disclosed. The electrode includes an active surface for ablating and/or coagulating tissue in an electrosurgical procedure. The insulating piece surrounds the active surface and provides a barrier for the intense heat created during ablation. The insulating piece is also electrically nonconductive to prevent unwanted discharge of energy. Electrode has a retaining ledge configured to engage a lip formed on the insulating ring. The insulating ring is secured to the electrosurgical device by connecting the electrode to an electrode seat and capturing the insulating piece in between. The electrode can be connected to the electrode seat by projection welding. The insulating piece is connected to the electrode without the use of an adhesive.
