③ lifting the pushing clamping fixed seat upwards, then unloading the pushing clamping rod, then making the pushing clamping fixed seat descend under the gravity action of the weight, simultaneously lifting the pushing tube upwards for a certain height and keeping stable, and further making the ring electrode separate from the esophageal tube and match with the tumor part;
④, inflating the opening air bag through the air pump to make the ring electrode generate certain deformation, and further make the ring electrode touch the tumor part of the esophagus wall;
⑤, generating high voltage direct current by the power distribution controller to form a strong electric field around the ring electrode, thereby completing the inactivation of the tumor part of the esophageal wall.
The invention has the beneficial effects that:
1. the annular electrode is used as a working part, the push pipe is used as a feeding medium, and the tumor cells in the wall of the peripheral esophagus can be inactivated by an electric field generated by direct-current high voltage in an equipment using mode with characteristics.
2. The design of the insulating weight can not only ensure that the annular electrode is pushed to the inner wall of the esophagus along with the pushing pipe, but also generate relative displacement with the pushing pipe, so that the annular electrode directly acts with the tumor part.
3. The design of the air bag is opened, so that the annular electrode can deform to a certain degree, the annular electrode can directly contact with tumor tissues in the esophageal wall, and the inactivation treatment effect is improved.
4. The structural design of propelling movement screens cover and propelling movement screens pole can ensure to make annular electrode can with the propelling movement pipe synchronous propelling movement in the propelling movement, has ensured the efficiency of propelling movement, does not influence the subsequent relative motion of the two simultaneously.
