Electrosurgical technical ceramic components

Alumina (aluminum oxide, Al2O3) technical ceramics are commonly used in electrosurgical instruments due to their generally useful properties and good price/performance ratio. Alumina ceramics are commonly subdivided according to their alumina content ranging from 80% to more than 99%. Higher purity alumina demonstrates enhanced wear and corrosion resistance — creating a continuous scale of various alumina grades, compositions, and performance.

Ceramic Ablator Insulator Case Study

Velocity Orthopedics 3.3mm Bipolar Aspirating Ablator

This bipolar aspirating ablator features a CoorsTek ceramic ablator insulator with the unique capability to resect and liberate tissues from boney surfaces. The ceramic insulator is bioinert and provides both electrical insulation and thermal management (see video).

CoorsTek Manufacturing Capabilities

  • Ceramic micro injection molding - Injection molding eliminates the need for secondary operations normally required to produce complex geometrical shapes. The more complex the shape, the more advantageous injection molding will be over other fabrication methods.
  • Sub-assembly & micro-machining
  • Transparent materials available
