Question

An electrosurgical unit (ESU) is integrated into the vision cart. It provides monopolar and bipolar energy to dV Xi energy instruments. Can it also be used with laparoscopic instruments if needed?

Answer 1

Yes, an ESU that provides monopolar and bipolar energy can be used with traditional laparoscopic instruments as well as dV Xi energy instruments.

Step-by-step explanation:

The electrosurgical unit (ESU) you're asking about can be used with both dV Xi energy instruments and, as needed, with traditional laparoscopic instruments. The key is that the ESU provides both monopolar and bipolar energy suitable for diverse surgical procedures. Regarding the flow of current from a scalpel, electric fields are more concentrated at the sharp edges of conductors, which results in most current flowing from these points.

Electrosurgical procedures concentrate current at the scalpel's sharp edges using high-frequency AC to enhance precision.This concept is crucial in electrosurgery to help with precision cutting and coagulation. Moreover, high-frequency alternating current (AC) is typically used in electrosurgery because it cuts and coagulates tissue effectively while minimizing heat spread and collateral damage.
