Description

A lavage device for handling joint hydrops

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an irrigation device for treating joint effusion.

Background

Knee osteoarthritis is an acute and chronic aseptic inflammatory disease, has the main clinical manifestations of joint swelling and pain, deformity and limited movement, and is good for middle-aged and old people. The aseptic inflammation is generated at the starting and stopping points of local muscles of articular cartilage, synovial membrane, sclerotin and ligament due to acute and chronic injuries, the functions of normal synovial membrane and metabolic balance in joints are seriously damaged by the inflammatory factors, increased leucocytes, cartilage debris particles and the like, and malignant circulation is formed due to untimely rest and treatment, so that the destruction of synovial articular cartilage and even sclerotin occurs, the effusion of joint cavities is increased, the local pressure is changed, the ischemia and anoxia of local tissues are caused, and the metabolic nutrition disorder causes clinical symptoms. Inflammatory adhesion and contracture of surrounding soft tissues are caused for a long time, biomechanics is changed, synovial lesions and protective decline of the soft tissues to joints are aggravated, so that patients dare not to move, the functions of the whole body are also declined, the life quality is declined, and early and timely treatment is necessary.

At present, many methods for clinically treating the liquid-accumulating gonarthritis are mainly divided into a drug therapy, a conservative therapy and an operative therapy. The effect is not ideal and the side effect is large when the medicine is taken orally for a long time. The risk is high during operation treatment, the joint cavity is easy to be damaged, and the patient is not easy to accept. Conventional conservative treatment has low cure rate and easy relapse. The knee joint lavage therapy is a simple and effective method, and is commonly used for treating suppurative arthritis, gouty arthritis, joint extrusions, joint effusion and joint synovitis in clinic. The lavage therapy of knee joint is mainly to wash out the falling debris, small free body, cellulose, denatured joint liquid, etc. to benefit the stability and recovery of the environment in the joint cavity.

The applicant has found that the prior art has at least the following technical problems:

the existing lavage therapy for knee joint is: taking a patient in a supine position, fully exposing a knee joint, paving a sterile hole towel after conventional iodophor disinfection, selecting a joint cavity needle insertion puncture point, puncturing the joint cavity after local anesthesia is carried out by 1ml of 2% lidocaine, completely sucking accumulated liquid in the joint cavity, pulling out an injector, and discharging the pumped-back accumulated liquid to a waste liquid barrel; then the injector is inserted into the normal saline bag, 100ml of normal saline is extracted, the injector is pulled out from the normal saline bag and inserted into the end of the cleaning tube, the normal saline is rapidly injected into the joint cavity, then the mixed liquid in the joint cavity is completely pumped back by the injector, the operation is repeated for 2-3 times, and the joint cavity is repeatedly washed through the process until the pumped back liquid is clear.

This kind of mode that utilizes scavenge pipe and syringe to carry out joint chamber lavage needs the syringe needle lavage or the suction of separation syringe repeatedly, makes the joint chamber be in open state and leads to the infection of going backwards easily, and the step is many, complex operation, scavenge pipe, syringe, normal saline water bag and waste liquid bucket between be the independent structure, need make up at clinical well scene during the use, operate inconvenient, waste time and energy, also lead to easily not finding because of putting the problem, work efficiency reduces.
