How to Judge the Quality of a ESU

How to judge the quality of a Electrosurgical Unit

      Electrosurgical Unit has a wide range of applications in surgery. In addition to being widely used in general surgery, brain surgery, chest surgery, facial features, etc., it is also increasingly used in endoscopic minimally invasive surgery. Its advantages are fast cutting speed and coagulation effect. Compared with traditional scalpels, it can greatly reduce operation time and intraoperative bleeding.

      A  Electrosurgical Unit generally has several functions: (1) output power indication; (2) power preset and adjustment; (3) patient plate detection alarm; (4) working audio indication; (5) output port Anti-misplug function; (6) Hand control and foot control functions.

     For a high-quality electrosurgical Unit, the allowable error in output power under different workloads is 20% according to the testing technical specifications. Adjust the following parameters: the power of bipolar, electrocution, and electrocoagulation are 50, 100, and 100 W respectively; the delay is generally set to 300 to 500 ms. After the above parameters are adjusted, set the load to 10,100, 200, 500, 1 000 Ω in sequence according to the original record requirements, wait about half a minute after each change to stabilize the test data, and record the tester monitoring data. According to the testing technical specifications of the military trial, the allowable error of the output power is plus or minus 20%, and Pmax is less than or equal to 400 W. The high-frequency leakage current must be less than 150ma, and it must have various error and alarm functions.

     Through the testing of Electrosurgical Unit quality control, not only the reliability of its clinical application is guaranteed, but also the safety of patient treatment and surgery is guaranteed, and the performance of the equipment itself is guaranteed.
