Working principle: When treating the popliteal fossa cyst at the joint, in the initial state, open the tube clip I8, and the gas is sucked into the chamber I6b and the chamber II6c by the trachea into the chamber I6b and the chamber II6c, so that the entire pressing sphere 6 is all bulged. (Add gas), then close the tube clamp I8, the tube clamp II10a prevents the alcohol from the liquid tank 10 from flowing out, the tube IV3b is not inserted into the tube II2e, and then puncture under the guidance of B ultrasound; the puncture tube 1 is punctured, because the puncture tube 1 is an "L"-shaped metal tube with a sharp tip, which is convenient for puncturing. When it is confirmed that the popliteal cyst is successfully punctured, the tube IV3b is inserted into the tube II2e, and the fluid in the popliteal cyst will not flow out. At this time, press and press it with your thumb. The inwardly concave arc-shaped groove at the top of the sphere 6, the remaining fingers (or part) press the inwardly concave arc-shaped groove at the bottom of the sphere 6, and then squeeze it hard, while opening the tube clamp III9b, the gas in the chamber I6b is directed to the popliteal fossa. The cyst flows away, and the one-way valve I4a conducts the chamber II6c to gradually discharge the gas in it through the collecting tank 9. When the pressing ball 6 is completely collapsed, the air pressure at the popliteal cyst is slightly higher than the negative pressure of the chamber II6c. Open the one-way valve II5a, and the liquid from the popliteal cyst will drain out. Repeatedly add air to the pressing ball 6. After several times, open the pipe clamp II10a. It means that the alcohol has completely filled the popliteal cyst, and the liquid in it has been drained. Due to the high alcohol content, it can cause cautery damage to the cyst wall tissue, causing the cyst wall tissue to adhere, shrink the cyst cavity, and then close, and finally disappeared. After the treatment, the puncture tube 1 was removed. Because the puncture wound was small, it had no effect on the joint, and there was no wound scar after healing. If the popliteal cyst recurs, this device can be used repeatedly to treat the recurring popliteal cyst. The invention has the characteristics of small trauma, light pain, quick recovery and repeatability, and has no influence on the work and life of the patient during use.

A single tube, that is, except the puncture tube 1, is used to puncture the popliteal cyst, drain the fluid in the popliteal cyst after puncture, and inject alcohol into the popliteal cyst after the fluid has been drained. The operation is simple and does not require a tube. The extraction and insertion between the body and the puncture tube 1 saves the operation time, simplifies the operation process, does not cause the contact between the wound and the air, and avoids infection. It is only 0.6 times the sum of the diameters of the two puncture tubes, so that the operation time is shorter, the puncture trauma is smaller, the pain is lighter, and the recovery is faster, and a mesh bag 9a is set in the liquid collecting tank 9, and the mesh bag 9a is filled with acetic acid. Calcium granules or powder can let the doctor know whether the fluid in the popliteal cyst has been drained.
