The cooperation of the head is more conducive to the release of the joint cavity adhesion.

After flushing, loosen the finger pressure valve 3, the finger pressure valve 3 will automatically reset under the action of the spring, and the water circuit will be cut off; when it is necessary to absorb water, see Figure 11, press the negative pressure switch 1057, and press the finger of the water suction chamber 42. Pressure valve 3, the effusion is sucked into the needle tube 201 by the needle eye 2011, enters the bottom of the flushing chamber 41 from the end of the needle tube 201, and then enters the water suction chamber 42, and then enters the waste liquid recovery through the water suction internal connection 16, the water suction connection pipe 14, and the water suction external connection 10. bottle. During the entire flushing process, the water pressure and the amount of flushing can be adjusted. After the flushing treatment, the needles are taken out, and there is no need for sutures, and sterile dressings are attached.

The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited by the above-mentioned embodiments.
