when the joint cavity needs to be washed, referring to fig. 10, the positive pressure switch 1055 is pressed, the finger pressure valve 3 of the flushing cavity 41 is pressed, water enters the flushing connecting pipe 13 from the flushing external connector 9, then enters the flushing channel 43 through the flushing internal connector 17, then enters the flushing cavity 41, and finally is ejected by the needle eye 2011 for flushing, the flushing direction of the needle eye faces the inclined direction of the release head, during flushing, the flushing direction faces the side of the release head, impact force is formed, and the joint cavity adhesion can be better released through matching with the release head.

After the flushing is finished, the finger pressure valve 3 is released, the finger pressure valve 3 automatically resets under the action of the spring, and the water way is cut off; when water absorption is needed, referring to fig. 11, the negative pressure switch 1057 is pressed, the finger pressure valve 3 of the water absorption cavity 42 is pressed, and the accumulated liquid is absorbed into the needle tube 201 through the needle eye 2011, enters the bottom of the water absorption cavity 41 from the tail end of the needle tube 201, then enters the water absorption cavity 42, and then enters the waste liquid recovery bottle through the water absorption inner connector 16, the water absorption connecting tube 14 and the water absorption outer connector 10. The water pressure and the flushing and sucking quantity can be adjusted in the whole flushing and sucking process, after flushing treatment, the needle tool is taken out, no needle needs to be sewed, and sterile dressing is attached.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
