Providing a multi-character material as part of a coating of an electrosurgical instrument. The multi-character material includes molecular chains having a hydrophobic characteristic or charged unit that bonds to a metallic substrate and/or a base material coating layer of the tip, and a hydrophilic characteristic that provides desired properties to the coated surface, such as the ability to attract water to assist in cooling and/or lubricating an electrosurgical tip, to create a low shear, sacrificial layer that protects and enhances eschar release characteristics, to supply a radical scavenger or inhibitor that reduces damage at the tip, and/or to deposit factors, such as healing factors, from the tip onto one or more contact surfaces of the patient's body. Optionally, an additional covering layer of a hydrophilic material may be applied over the multi-character material coating layer to increase the desired properties at the coated surface.
提供一种多特性材料,作为电外科器械涂层的一部分。多特性材料包括具有疏
水特性或带电单元的分子链,可与
金属基底和/或针尖的基底材料涂层结合,还具有亲
水特性,可为涂层表面提供所需的特性,如吸
水能力,以帮助冷却和/或润滑电外科手术针尖、形成低剪切力的牺牲层,以保护和增强焦痂释放特性;提供自由基清除剂或
抑制剂,以减少针尖的损伤;和/或将因子(如愈合因子)从针尖沉积到患者身体的一个或多个接触面上。可选择在多特性材料涂层层上再覆盖一层亲
水性材料,以增加涂层表面所需的特性。
