Description

Shoulder joint internal and external rotation activity measuring device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a shoulder joint internal and external rotation activity measuring device.

Background

The shoulder joint mainly comprises a scapula glenoid and a humeral head, is the most flexible joint of the whole body, and can perform activities in all directions such as forward flexion, backward extension, adduction, abduction, lifting, annular rotation, internal rotation, external rotation and the like. The movement function of the shoulder joint is closely related to the functions of nerves, muscles, bone joints and the like, and when the shoulder joint is diseased or suffers from trauma, the shoulder joint often has abnormal functions. The shoulder joint disease or the trauma position can be judged by observing and analyzing the abnormal function condition of the shoulder joint, and the reason of the shoulder joint disease is presumed. The measurement of the activity of the shoulder joint is an important method for evaluating the function of the shoulder joint, is an important evaluation item in most evaluation scales, and has important clinical significance.

At present, the measurement of the shoulder joint activity is mostly finished through a joint angle ruler, although the method is simpler and more convenient, larger errors exist, particularly when the shoulder joint internal rotation and external rotation activity is measured, the shoulder joint is required to be outwards expanded to a certain angle, the shoulder joint internal rotation and external rotation activity is reflected by measuring the swinging angle of the forearm, if the shoulder joint external expansion angle is insufficient, the trunk can block the forearm to influence the completion of the shoulder joint rotation activity, and therefore, the measurement cannot be finished when the shoulder joint external expansion activity is limited and the elbow joint and the forearm of a patient are abnormal. Meanwhile, the internal rotation and external rotation activities of the shoulder joint are maximum at rest positions where the upper limbs drop, and along with the increase of the abduction angle, the tension of the muscle ligaments around the shoulder joint, the internal rotation and external rotation activities of the shoulder joint are reduced, so that the real conditions of the functions of the shoulder joint cannot be reflected well when the internal rotation and external rotation activities of the shoulder joint are measured in a larger abduction position, the application scene of the traditional device is limited, the measurement in the sitting position, the standing position, the lying position and the like cannot be met at the same time, and the use limitation is obvious.

The currently designed shoulder joint mobility measuring device mostly cannot finish the measurement of the mobility of internal rotation and external rotation of the shoulder joint, such as: the CN216021033U shoulder joint mobility measuring device published by 2022.03.15 can only complete shoulder joint protrusion and abduction mobility measurement; CN216455000U published 2022.05.10 is a portable measuring ruler for the degree of shoulder joint movement, which can only measure the degree of shoulder joint horizontal and vertical movements. The novel shoulder joint mobility measuring device of CN216439192U published by 2022.05.06 can finish the measurement of the internal rotation and the external rotation of the shoulder joint, but the whole device is large in size and inconvenient to place, and a patient needs to stand above a measuring plate during measurement and needs forearm participation, so that the measurement can be difficult to finish when the patient is difficult to stand, and the elbow joint and the forearm are abnormal, and the application range is limited.
