Lower arm skeleton motion simulation structure

Abstract

The invention discloses a lower arm skeleton motion simulation structure which simulates the human body. The lower arm skeleton motion simulation structure is provided with an ulna and a radius which are paratactic, the ulna is connected with the radius through a cardan joint, and one end, provided with a side-direction protrusion body, of the ulna is hinged with one end, corresponding to the side direction, of the radius through a universal joint pin. The other end, in the side direction, of the radius is hinged with the other end, in the corresponding side direction, of the ulna also through a universal joint pin. The side-direction hinged structure enables the ulna and the radius to be connected in parallel connection and to stimulate a position relationship between the ulna and the radius in the human body. By the adoption of the cardan joint connecting, the lower arm is enabled to twist. The ulna and the radius which are parallel can be staggered in two directions to form the whole skeleton of the lower arm to twist with angles to stimulate rotatory motion of limited twist cooperated by the lower arm skeleton, muscle and tendon to form a flexible movement which simulates the lower arm of the human body and the skeleton. The lower arm skeleton motion simulation structure is ingenious in structure, simple in manufacture and well stimulates a relational structure of the ulna and the radius and a twist relationship relative to the big arm. In processes of teaching and training, a good study effect and teaching aims are achieved.

Description

technical field [0001] The invention relates to medical teaching equipment, in particular to a lower arm bone motion simulation structure. Background technique [0002] Due to the failure to solve the structural problems of bone motion simulation, the existing various humanoid models often result in limited functions and distorted images. In particular, the bones of the lower arm are composed of the ulna and the radius, and the movement process depends on the ulna and the radius. The elbow joint between the two ends of the radius and the humerus of the big arm and the wrist joint between the palm and the tendons and muscles form the action. In particular, the twisting of the lower arm composed of the ulna and radius is formed by the action relationship of the elbow joint and tendons and muscles between the upper ends of the ulna and radius and the humerus of the big arm. Such complex structures are difficult to manufacture and produce. At present, in the teaching operation...

Such a complex structure is difficult to manufacture and produce

At present, in medical teaching and training, the use of lower arm bones cannot make the training more realistic, nor can it achieve good results and learning purposes.
