[0002] Rheumatic diseases are a group of extremely common clinical syndromes with joint pain and fear of cold as the main symptoms. Rheumatism is the abbreviation of rheumatic diseases, which generally refers to a large group of diseases that affect bones, joints, muscles and surrounding soft tissues such as bursae, tendons, fascia, blood vessels, nerves, etc.

[0003] Inflammatory exudation within the joints or between soft tissues is the direct cause of local swelling and pain in rheumatic diseases. In particular, the inflammatory factors, immune complexes and enzymes contained in the inflammatory synovial fluid within the joints are the main causes of local immune reactions in the joints. If the inflammatory synovial fluid can be cleared in time, it will help to quickly eliminate local and systemic symptoms and restore the body's functions as soon as possible.

[0004] Among the existing technologies, the following are dedicated to needle innovation: CN201320859276.6 "A joint cavity flushing needle", which includes a flushing needle and a flushing needle core. The flushing needle core is placed in the flushing needle. The flushing needle includes a needle tube, a needle and a needle handle.
