Description
Technical Field
The invention relates to a wrist joint loosening operation training instrument in the field of teaching and training.
Background
With the development of rehabilitation therapy, more and more people are aware of the importance of rehabilitation, and joint loosening is a common technique in rehabilitation therapy and is accepted by more and more therapists. In daily teaching, the teaching of the joint loosening operation is more and more important, but the practice effect of students on the actual operation course is not ideal.
The normal joint movement of a human body comprises physiological movement and accessory movement, the movement of the joint completed in a physiological range is called physiological movement, the movement performed in an anatomical structure range is called accessory movement, the normal movement of the joint is indispensable movement for maintaining the normal movement of the joint, and when the movement of the joint is limited due to pain and stiffness, the physiological movement and the accessory movement of the joint are limited. If the joint is still painful or stiff after recovery of physiological motion, it is possible that the collateral motion is not completely restored to normal. Thus treating joint pain, stiffness, limited mobility, etc. in a manner that improves joint articulation. The joint loosening operation is an operation technique for improving joint motion, and the basic operations include swinging, rolling, sliding, separating and pulling, and in short, the joint loosening operation is a relative motion between joints.
In the traditional teaching course, a simulated wrist joint is used for students to learn and operate, and the students learn the technical action of the wrist joint loosening operation by operating the simulated wrist joint. The teacher needs to observe whether the technical actions of the students are in place or not beside the students to guide the students, and the simulated wrist joints are of two types, one type only comprises simulated bones and does not comprise simulated skins, and the problems of the simulated wrist joints are two types: 1. the simulated wrist joint without the simulated skin is greatly different from a real human body, and even if a student is skillfully operated on the simulated wrist joint, various problems can be caused when the student is operated on the real human body; 2. when the student operated emulation wrist joint, the hand of student's operation was painted and is sheltered from mr's field of vision, and whether mr can't the direct observation student all operations are standard, consequently can't carry out very effectual technical guidance to the student, leads to the educational effect very limited. The other simulation wrist joint is provided with simulation skin and simulation bones, the simulation wrist joint is close to a real human body, but the existence of the simulation skin can lead a teacher to shelter whether the bones act in place, and similarly, the hands of students can also block the visual field of the teacher, so that the teacher can not accurately observe whether the simulation bones act in place, the students can not accurately conduct action guidance, and the education training effect is poor.
