[High frequency current in endoscopic surgery and a new bipolar hook for endoscopic surgery].
High frequency current is used in surgery for cutting the tissue and stopping bleeding. Its usage is more frequent in endoscopic than open surgery. "Polarity" (monopolar and bipolar) marks the number of the electrical poles on the application place. Monopolar current has been used more often. With its usage thermal injuries are possible: coagulation outside of the laparoscopic view, direct coupling, capacitive coupling, sparking, skin combustion, activity on the heart rhythm. Because of these complications, the bipolar current is more and more in usage, which reduces the number of complications or avoids them completely. Many bipolar instruments are available today. Bipolar hook for endoscopic surgery is a new instrument which unites the good characteristics of the hook and bipolar current.
