Further, the end of the delivery line second sets multiple-way valve, and the delivery line is described respectively by the multiple-way valveAt least two are connected in negative pressure device, the argon gas device, the water delivery device.
Further, dissector also includes lighting device in the art of the interchangeable bit, and the lighting device is arranged onThe handle front end.
Further, the lighting device is rotatable, and its focus is mutually chain with the position of the electrode, described when in useLighting device illuminates the electrode cutting position all the time.
Further, the lighting device is powered by the way of external power supply, be not provided with internal battery, it is to avoid built-inBattery causes secondary pollution to dissector in the art of the interchangeable bit.
Further, the lighting device is controlled by two pieces of control panels respectively with the electrode.The illuminationDevice and the electrode use one piece of control panel, and signal can be produced to disturb, and cause electrode letter in useNumber mistake.
The beneficial effects of the present invention are it is following some：
1. draw-in groove is set, and supporting multiple electrodes, can in operation quick-replaceable difference purposes electrode, only use oneIon radio-frequency electrode can just be completed an operation, reduces cost facilitates doctor to operate simultaneously.
2. lighting device is set, and lighting device illuminates the electrode cutting position all the time when in use, can facilitate doctorObservation.Lighting device is not provided with battery and can effectively prevent pollution of the battery to dissector in the art of interchangeable bit, it is also possible toEliminate electromagnetic interference of the lighting device to control panel.
3. set and lead smoke pipe, can realize extracting out flue gas by external distinct device, extract diffusate out, be passed through argon gas, logicalEnter various functions of cleaning fluid, while being conducive to doctor to observe, protect that doctor's is healthy；
4. set multiple control panels to control respectively, eliminate signal interference, make operation more accurate.
