Abstract
The cutting surfaces of electrosurgical instruments are provided with an electroconductive coating of an inorganic silicon-containing non-stick material such as amorphous silica deposited thereon by plasma enhanced chemical vapor deposition.
Claims16
An electrosurgical cutting instrument comprising a stainless steel body having a cutting edge, said stainless steel body having a non-stick, electroconductive coating of substantially pure amorphous silica deposited on at least the cutting edge by plasma enhanced chemical vapor, said coating being of a thickness that provides electroconductivity when subjected to electrical source generated hemostatic and cauterizing currents during surgery.
An electrosurgical cutting instrument comprising a stainless steel body having a cutting edge, said stainless steel body having a non-stick, electroconductive coating of an inorganic disilicide deposited on at least the cutting edge of said instrument, said coating being of a thickness that provides electroconductivity when subjected to electrical source generated hemostatic and cauterizing currents during surgery.
A process for the manufacture of an electrosurgical instrument comprising coating at least the cutting edge of a stainless steel electrosurgical instrument with substantially pure amorphous silica, said coating imparting non-stick characteristics to the cutting edge and being of a thickness that provides electroconductivity when subjected to electrical source generated hemostatic and cauterizing currents during surgery.
A process for the manufacture of an electrosurgical instrument comprising coating at least the cutting edge of a stainless steel electrosurgical instrument with an inorganic disilicide, said coating imparting non-stick characteristics to the cutting edge and being of a thickness that provides electroconductivity when subjected to electrical source generated hemostatic and cauterizing currents during surgery.
