摘要：
An apparatus, a system and a method of dissipating an electrical charge are provided. The apparatus is a cannula for receiving a surgical instrument to perform a surgical operation on a body. The cannula includes a hollow elongated structure having a proximal end opening and a distal end opening leading to a hollow interior passage dimensioned to receive a surgical instrument. The hollow elongated structure includes a polymer material and an electrically conductive material. The electrically conductive material is disposed to achieve electrical capacitive coupling with the surgical instrument and to dissipate an electrical charge received via the electrical capacitive coupling. The system and method utilize the cannula to dissipate the electrical charge through the surgical instrument.
