Description

Stress test device for ligament test with improved convenience {A Stress Test Device For Testing Ligament With Easy Of Use}

The present invention relates to a stress testing device for testing ligaments with improved convenience, and more particularly, to a stress testing device for testing ligaments capable of quickly disposing joints at various angles in various positions.

In general, bone or ligament rupture is governed by the force, speed, and direction acting on the bone or ligament. Test methods used to determine whether or not the rice or ligament is ruptured are largely divided into the musculoskeletal examination method and the stress test method.

The musculoskeletal examination method is a method in which the examiner manually bends the patient's leg and then pushes and pulls it backward to diagnose the degree of fracture and ligament rupture. This method has a disadvantage in that the degree of rupture is diagnosed by the examiner's senses and the patient's response, so the accuracy is relatively low.

The stress test method is to apply a certain force to the ruptured part for a certain period of time to determine whether or not there is a rupture of the ligament, and judge the presence or absence of abnormalities according to the degree of deformation. Diagnosis is made by comparison with the normal leg. Unlike the musculoskeletal examination method, this stress test method has recently been generally used because it can accurately determine the presence or absence of an abnormality regardless of the skill level of the examiner.

An inspection device is being developed so that it can be used for such a stress inspection method, but it has several problems and needs to be improved.

That is, in the conventional inspection device, since the part for adjusting and supporting the angle of the knee is disposed only at a specific location, it is limited to quickly adjust the angle of the knee at various angles.
