Abstract

Provided is a simplified combined device used for knee joint cavity lavage. The invention relates to the field of medical instruments. The structure comprises a puncture needle, a guide wire, two irrigation catheters, two transfusion devices, and two drainage devices. Using the above structure, the two irrigation catheters are respectively put in a join cavity through two sides of a knee joint, and the irrigation catheters are respectively connected with the transfusion devices and the drainage devices. Firstly, a flow velocity regulator of the transfusion device on a side is switched on, and the flow velocity regulator of the drainage device on the same side is switched off, the flow velocity regulator of the transfusion device on the opposite side is switched off, and the flow velocity regulator of the drainage device on the opposite side is switched on, and thus, the joint cavity is lavaged. Then, the open flow velocity regulator of the transfusion device on one side is switched off, and the flow velocity regulator of the drainage device on the same side is switched off, and the flow velocity regulator of the transfusion device on opposite side is switched on, and the flow velocity regulator of the drainage device on the opposite side is switched off, and the joint cavity is lavaged in a crossed manner. The simplified combined device used for knee joint puncture lavage is simple in structure, and can effectively lavage joint cavities, and is economical and practical.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a simplified combined device for knee joint cavity lavage. Background technique [0002] Knee arthritis is a chronic disease of knee cartilage degeneration and secondary bone hyperplasia caused by various factors. It mostly occurs in middle-aged and elderly people. , often accompanied by joint effusion, seriously affecting the quality of life of patients. [0003] At present, for knee joint patients with joint effusion, the treatment method of repeatedly puncturing and extracting the effusion with a syringe is usually used clinically. The lavage treatment of the knee joint cavity cannot be implemented, so the lavage treatment of inflammatory factors in the knee joint cavity is insufficient. For patients with severe knee joint effusion, knee arthroscopic treatment is usually used clinically. Although this treatment method is relatively thorough, it requires high technical skil...
