1. A surgical system, comprising:
- an introducer device adapted to deliver a plurality of surgical instruments to a site within a patient'"'"'s body;
a first surgical instrument comprising an active electrode probe having a tip and being adapted for connection to an electrosurgical generator for effecting at the tip thereof an electrosurgical procedure within the patient'"'"'s body, the first surgical instrument adapted to be deployed through the introducer device;
a second surgical instrument for performing a non-electrosurgical procedure, the second surgical instrument adapted to be deployed through the introducer device;
a conductive shield surrounding the active electrode probe of the first surgical instrument and connected to a reference potential; and
a cold instrument monitor connected to the second surgical instrument and to the reference potential, whereby any current which flows from the active electrode probe to the second surgical instrument is conducted to the reference potential, wherein the cold instrument monitor comprises;
a sensing tube surrounding at least a portion of the second surgical instrument and;
first and second contact monitors connected to the second surgical instrument, the first and second contact monitors electrically coupled to a connection monitor, the connection monitor adapted to determine one or more of the voltage, current, impedance and resistance generated at the first and second contact monitors.
