Non-stick coated electrosurgical instruments and method for manufacturing the same

An end effector assembly including a pair of opposing jaw members, each of the jaw members comprising:

• a support base;
• an electrical jaw lead;
• a sealing plate coupled to the electrical jaw lead and the support base, the sealing plate having a stainless steel layer;
• a titanium nitride coating disposed over at least a portion of the stainless steel layer;
• a chromium nitride coating disposed over at least a portion of the stainless steel layer;
• and
• a hexamethyldisiloxane plasma coating disposed over an entirety of an outer surface of the jaw member including an outer surface of the support base and the sealing plate including the chromium nitride coating.

A method of manufacturing an electrosurgical instrument, comprising:

• applying a titanium nitride coating to at least a portion of an electrically conductive surface;
• applying a chromium nitride coating to at least a portion of an electrically conductive surface to form a coated electrically conductive surface;
• assembling the coated electrically conductive surface to a treatment member by affixing the coated electrically conductive surface to a support base to form an assembled treatment member;
• and
• applying a hexamethyldisiloxane plasma coating over at least a portion of the assembled treatment member including both of the electrically conductive surface and the support base.
