定义
A precision-engineered cylindrical component designed for high-frequency electrosurgical electrodes that provides both structural integrity and electrical insulation between the active electrode tip and the surgical instrument handle. It prevents current leakage and ensures patient safety during electrosurgical procedures by maintaining dielectric isolation while withstanding mechanical stresses during surgical manipulation.
工作原理
The insulated shaft operates by creating a dielectric barrier between the conductive electrode tip and the instrument body, preventing unintended electrical current flow to non-target tissues. It maintains the high-frequency current path exclusively through the active electrode while providing mechanical stability for precise surgical control.

Medical-grade ceramic (Alumina 99.5% or Zirconia)PEEK (Polyether ether ketone)or PTFE (Polytetrafluoroethylene) with dielectric strength >15 kV/mmbiocompatibility per ISO 10993and autoclavable properties.
Length
150-300 mm
Diameter
3-6 mm
Surface Roughness
Ra < 0.8 μm
Dielectric Strength
