The invention provides a radio frequency plasma power planing system which comprises a main machine and a handle. The handle is connected with the main machine, and the main machine comprises a radiofrequency plasma generating device and a power controller. The handle includes a handle motor, a tool bit and an electrode. The handle motor is connected with the tool bit, the electrode is connectedwith the tool bit, and they are mutually conductive. According to the radio frequency plasma power planing system, plasma and the tool bit are matched with each other for cutting, sawing, grinding andother treatments on human tissues, and the radio frequency plasma discharge forms a plasma thin layer at the front end of the tool bit, so that the tool bit is sharper, the operation time is shorter,the precision is higher, the pain of a patient is reduced, and the operation risk is reduced; meanwhile, the plasma thin layer decomposes the contacted human tissue cells, the effects of cutting, ablation and hemostasis are achieved, and large amount of blood and a large amount of tissue debris are prevented from being generated in the operation process.
