Description

This invention relates to an electrosurgical generator designed to output a high-frequency AC voltage to an electrosurgical instrument. The electrosurgical generator comprises a main control unit and a high-voltage inverter that generates a high-frequency voltage having a variable frequency and amplitude, which is supplied to an output socket for connection to the electrosurgical instrument. In electrosurgery or radiofrequency surgery, high-frequency alternating current is applied to human tissue using electrosurgical instruments such as electrosurgical scalpels. Typically, high frequencies in the radio frequency range of approximately 200 kHz to a maximum of 4,000 kHz are used. The high-frequency alternating current locally heats the tissue. This causes the tissue to be cut or separated by heat, and the tissue is removed by thermal excision. The main advantage of this method is that bleeding can be stopped simultaneously with the cut by closing the affected blood vessels, allowing the electrosurgical instruments to be used for other purposes such as coagulation. To provide electrosurgical generators for various medical fields, different types of electrosurgical generators are required, each with different components and distinct functionalities. These are used for various tasks in different surgical fields, such as urology, gynecology, gastroenterology, respiratory medicine, ENT (ear, nose, and throat), venology, and visceral surgery, to name a few. The function of an electrosurgical generator varies depending on the medical field and the task at hand. In particular, these functions differ in how power is supplied to the electrosurgical instrument. The various methods of supplying power to the electrosurgical instrument are typically referred to as "modes" by those skilled in the art. If only tissue cutting should be achieved, a cutting mode is selected, continuously supplying a medium voltage to the electrosurgical instrument. If coagulation is more important, a different mode is selected, such as a spray or coagulation mode using a considerably higher voltage with a low duty cycle. Many more different modes exist for other types of applications. Therefore, different types of electrosurgical instruments are provided, each requiring different output sockets depending on the desired functionality. For example, there are monopolar and bipolar instruments that require monopolar and bipolar output sockets. Furthermore, there are also universal output sockets specifically configured to accept monopolar and bipolar electrosurgical instruments. All of this is managed by the main control unit of each electrosurgical generator. The main control unit controls the actual operation of the electrosurgical generator, including the high-frequency voltage applied to the output sockets and electrosurgical instruments, manages the user interface that displays the necessary data to the user, and processes user input. To facilitate user operation and avoid confusion about the function being used and what is actually supplied to the instrument by the output socket, it is common to use different presentation styles depending on the actual function used by the output socket. Therefore, the visual, acoustic, and functional representations of the standard "CUT" mode are yellow-based, and the visual, acoustic, and functional representations of the standard "COAG" (coagulation) mode are blue-based, but other modes are in different systems. This is a collaborative system that has the advantage of providing perceptual feedback to the user. However, collaborative systems are also closed systems that are difficult to expand or upgrade.
