Dear Sir I am Dr Snehlata your Student from Jalandhar. I want to know what is the principle of Versapoint and how it works. It is bipolar but how come it cuts in fluid environment? |

The Versapoint is a product of Ethicon and it is used in hysteroscopy with bipolar energy system which is used in operative minimally invasive procedure that allows the treatment of uterine lesions in the outpatient setting. It is a system that uses bipolar electrosurgical energy with small caliber electrodes (1.7 mm). The VersaPoint® technology is based on the basic principles of electrosurgery. It has been a breakthrough in hysteroscopic surgery, because although theoretically it is a monopolar system, the arrangement of the electrodes allows it to behave like a circuit of bipolar energy offering the versatility of the monopolar energy (cut and coagulation) and bipolar security. To this the small size of its electrodes, which allows performing outpatient procedures that previously, could only be performed in the operating room. The design of the electrodes is special in that the active electrode is located at the tip, and the return electrode on the handle. They are placed in separate with an insulating line. The required distension medium is normal saline, which does not alter the sodium concentration of cells as occurs with hypotonic solutions such as sorbitol or glycine thus avoiding the risk of fluid overload. Also provides a low resistance path that allows the energy generated to go back to the return electrode, without becoming part of the electrical circuit the patient's body. Currently there are 5 bipolar electrodes available on the market, three electrodes with different terminals for use with hysteroscopes with working channel of 1.6 to 2 mm each of which is designed for a specific task: spring (for vaporization), Twizzle (for cut) and ball (to coagulate), and two electrodes which can only be used with a resectoscope. (bipolar handle). |

Can I use 5% Dextrose if I am using versapoint for hysteroscopic myomectomy? |

Versapoint is Bipolar so it need normal saline or Ringer Lactate. It will not work in Glycine or Dextrose environment. |

Thanks Alisha for your answer but in my opinion versapoint does not cut as good as normal monopolar resectoscope. |
