Problems solved by technology
[0003] At present, for knee osteoarthritis accompanied by joint effusion, repeated joint puncture and fluid extraction are often used for treatment, which can achieve certain effects but is prone to recurrence and infection, and cannot thoroughly clean the metabolic waste in the joint; The advantages of less pain, short course of treatment, and good curative effect have been accepted by many rehabilitation departments and orthopedic surgeons. At present, joint irrigation is mostly performed by puncturing the inner and outer sides of the knee joint in a way of separating the inlet and outlet, which often increases the pain of the patient due to multiple punctures. Multiple puncture points also increase the chance of postoperative infection
