Abstract
An end effector assembly for use with an electrosurgical instrument is provided. The electrosurgical instrument includes a handle having a shaft that extends therefrom, an end effector disposed at a distal end of the shaft, at least one electrode operably coupled to the end effector and adapted to couple to a source of electrosurgical energy, a titanium nitride coating covering at least a portion of the electrode, a chromium nitride coating covering at least a portion of the electrode and/or titanium nitride coating, and a hexamethyldisiloxane plasma coating covering at least a portion of the chromium nitride coating.
Claims20
A surgical instrument, comprising:
- a shaft;
- an end effector disposed adjacent a distal end of the shaft, the end effector including a support base and at least one sealing plate coupled to the support base;
- at least one nitride physical vapor deposition coating covering at least a portion of the at least one sealing plate;
- and
- a hexamethyldisiloxane plasma coating covering the support base and at least a portion of the at least one nitride physical vapor deposition coating.
An end effector assembly, comprising:
- a jaw member including a support base and a sealing plate coupled to the support base;
- a nitride physical vapor deposition coating disposed on at least a portion of the jaw member;
- and
- a hexamethyldisiloxane plasma coating disposed on the support base and at least a portion of the nitride physical vapor deposition coating.
A method of manufacturing a surgical instrument, comprising:
- applying at least one nitride physical vapor deposition coating to at least a portion an electrode;
- coupling the electrode to a support base of the surgical instrument;
- and
- applying a hexamethyldisiloxane plasma coating to the support base and at least a portion of the electrode having the at least one nitride physical vapor deposition coating.
