ELECTROSURGICAL SMOKE EVACUATION FOR SURGICAL PROCEDURES

摘要

Various examples of the disclosed subject matter include systems and methods to control a flowrate of a smoke evacuation system. In one example, a smoke-evacuation system includes an electrosurgical unit (ESU) to provide electrical power to an electrosurgical tool within a surgical site. A monitoring device measures one or more electrical parameters from the electrosurgical tool and a controller estimates an amount of generated smoke within the surgical site based on the electrical parameters. The controller sets a flowrate of a suction device to remove gases within the surgical site. The flowrate of the removed gases produced is based on the estimated amount of generated smoke. The controller further controls a flowrate of an insufflation gas produced by an insufflation device where the flowrate of the insufflation gas is substantially equal to the flowrate of the gases produced by the suction device. Other systems and methods are disclosed.
