Abstract

The invention discloses a ligament rupture knee joint dislocation measuring device which comprises a dial indicator, a fixing block, a screw, a bracket and a bandage for binding the entire measuring device on the crus of a patient; the fixing block is firmly connected with the bracket; the screw passes through an internal threaded hole of a lug below the abdomen of the dial indicator and round holes at the two ends of the fixing block; the dial indicator is mounted above the bracket; a nut for axial positioning is mounted on the end part of the screw; a measuring head capable of keeping contact with the patient knee under the effect of a spring in the dial indicator is fixedly mounted at the front end of the dial indicator; and the bondage is fixed on the bracket. The entire device is bound on the crus of the patient by the bondage through the bracket, the measuring head of the dial indicator directly contacts with the patient knee, and when the doctor moves the crus of the patient back and forth, the knee joint dislocation caused by ligament hurt can be displayed on the dial indicator. The measuring device has a simple structure and low cost, and is convenient to use, quick, accurate and easy to popularize.

Description

technical field [0001] The invention relates to the fields of measurement technology and medical equipment, in particular to a contact-type measuring device for ligament rupture and knee joint dislocation. Background technique [0002] Knee ligament rupture or injury is a relatively common disease, more common in adolescents, more men than women, especially among athletes, often caused by strenuous exercise during training or competition. Sometimes you can hear the sound of ligament rupture when you are injured, and soon you can no longer continue to exercise due to severe pain, or swelling, tenderness and effusion appear in the knee joint, knee muscle spasm, the patient cannot move the knee, and the knee joint is in a forced Posture, or straightening, or bending, there are obvious tenderness points at the rupture of the lateral collateral ligaments of the knee joint, and sometimes the crumpled ligament stumps can be felt, which is one of the most harmful diseases.
