Surgical generators are medical devices capable of producing a cutting and coagulating clinical effect on tissue by the use of alternating current at high frequency. Voltages and currents can vary depending on the desired clinical effect. Surgical generators are also known as power supply or waveform generators. Advances in the past few years have led to electrosurgical generator unit circuitry capable of monitoring changes in voltage that occur during the delivery of electrosurgical energy. These electrosurgical generator units are capable of keeping voltage constant while power fluctuates to the lowest effective output, based on impedance within the circuit. This facilitates reproducible and consistent target tissue effects during electrosurgery.
Surgical generator is a part of electrosurgical instrument. There are two type of electrosurgical instruments: monopolar and bipolar. In monopolar instrument, the current leaves the generator and is conducted to the active electrode. Then the active electrode conducts it to the body. The conductive adhesive grounding pad is attached to a patient's body and will conduct the current back to the generator. In bipolar instrument, the current after leaving the generator goes to the active electrode then goes to patient's body and comes back for the other tip of the device, to the return electrode. The return electrode leads the current back to the generator.
Growing preference for minimally invasive procedures and increasing prevalence of chronic diseases such as cancer and kidney diseases are likely to fuel the global Surgical Generators Market. According to the World Health Organization, cancer is a leading cause of death worldwide, accounting for 8.8 million deaths in 2015. Increasing number of surgical procedures, growing awareness among people, rapid geriatric population growth, technological advancement, health care insurance coverage, and rapid population growth are the other drivers of the global surgical generators market. On the other hand, factors such as thermal damage or scar formation are likely to restrain the surgical generators market.
