The role of vessel sealing technologies in laparoscopic surgery

With the advent of new technology, it is crucial to understand the mechanics of how instruments work to fully be able to utilize them and prevent injury. One of the cornerstones which makes laparoscopy possible is the use of vessel sealing instruments. Cutting, coagulation, and dissection are some paramount qualities of vessel sealing instruments; however, knowledge of the type of energy being used on tissue is of utmost importance. The various forms of energy vessel sealing instruments have advantages and disadvantages depending on the task. In the following text, monopolar, bipolar, and ultrasonic vessel sealing instruments for laparoscopic surgery are discussed at length. From how these instruments work to their cost, a detailed look at the available and most widely used laparoscopic vessel sealing instruments is reviewed. The accompanying illustrations are to aid in recognition and understanding of their use.
