ELECTROSURGICAL BLADE WITH DIRECT ADHESION OF SILICON COATING

摘要

A stainless steel electrosurgical blade has a single uniform layer of release material comprising substantially silicone (polysiloxane) applied directly onto the stainless steel blade portion without the necessity of one or more coatings of primer material(s), or multiple layering of the release material or mechanical roughening of the metallic blade body. Adherence of the release coating is achieved by thermally oxidizing the blade body, after cleaning it. The uniform layer is created by dipping the blade body. The release material is preferably thermally cured and non-blooming.
