背景技术Background technique
膝骨关节炎是一种危害老年人健康的慢性进行性骨关节病，随着社会人口的老龄化，该病的发生也越来越多，主要症状表现为关节肿胀、疼痛、活动障碍，严重影响人们的工作和生活质量。目前对此病尚无满意的治疗方法。Knee osteoarthritis is a chronic progressive osteoarthritis that endangers the health of the elderly. With the aging of the social population, the occurrence of this disease is increasing. The main symptoms are joint swelling, pain, and mobility impairment. Affect people's work and quality of life. There is currently no satisfactory treatment for this disease.
目前对于伴有关节积液的膝骨关节炎多采用关节反复穿刺抽液治疗，对能取得一定效果但易复发、易感染，且不能彻底清洗干净关节内的代谢废物；而关节冲洗术以其痛苦小、疗程短、疗效好等优点被许多康复科及骨科医生所接受，目前关节冲洗多以进出口分开的方式进行膝关节内侧和外侧的穿刺，常因多次穿刺而增加患者痛苦，同时多个穿刺点也增加了术后感染的机会。因此如何在实际操作中，既能保证患者的疗效、安全又能减少患者的痛苦和花费成为了医生及患者必须考虑的重要问题。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. Therefore, in actual operation, how to ensure the curative effect and safety of patients and reduce the pain and cost of patients has become an important issue that doctors and patients must consider.
