Wrist joint loosening operation training instrument

Abstract

The invention relates to a wrist joint loosening operation training instrument which comprises a rack. An operation simulation wrist joint and a display simulation wrist joint which are arranged up and down are arranged on the rack, and the operation simulation wrist joint comprises a first simulation radius part and a first simulation metacarpal bone part which are arranged front and back; the display simulation wrist joint is composed of a second simulation radius part and a second simulation metacarpal bone part matched with the second simulation radius part, the first simulation radius part and the second simulation radius part are fixed to the rack, and the second simulation metacarpal bone part is connected with the first simulation metacarpal bone part through a synchronous connecting rod transmission mechanism; and when the first simulation metacarpal bone part moves back and forth, moves left and right, swings up and down and swings left and right relative to the first simulation radius part, the second simulation metacarpal bone part synchronously acts along with the first simulation metacarpal bone part. The invention aims to provide the wrist joint loosening operation training instrument which can be operated more close to a real human body and cannot affect a teacher to visually observe the skeleton movement range.

Description

technical field [0001] The invention relates to a wrist joint mobilization training instrument in the field of teaching and training. Background technique [0002] With the development of rehabilitation medicine, more and more people are aware of the importance of rehabilitation. Joint mobilization is a commonly used technique in rehabilitation therapy and is recognized by more and more therapists. In daily teaching, the teaching of joint mobilization is becoming more and more important, but the effect of the students' practice in the practical course is not ideal. [0003] The normal joint movement of our human body includes physiological movement and accessory movement. The movement of the joint within the physiological range is called physiological movement, and the movement within the anatomical structure is called subsidiary movement, which is an indispensable movement for maintaining normal joint activities. When joints are limited in activity due to pain and stiffnes...

AI Technical Summary

Problems solved by technology

The teacher needs to observe whether the technical movements of the students are in place to guide the students. There are two kinds of simulated wrist joints. One kind of simulated wrist joint only includes simulated bones and no simulated skin. There are two problems with this type of simulated wrist joint. : 1. There is a big difference between the simulated wrist joint without simulated skin and the real human body. Even if the students are proficient in operating the simulated wrist joint, there will be various problems when operating on the real human body; When the wrist joint is operated, the hand-painted operation of the student blocks the teacher's field of vision, and the teacher cannot dir
