<P>PROBLEM TO BE SOLVED: To provide an elbow joint diaplasis training model which can be reduced in manufacturing costs and has high reliability while realizing the sense of operation like a real one. <P>SOLUTION: An elbow joint diaplasis training model includes: a humerus model 2 and an antebrachial bone model 3 where a part equivalent to a humerus distal end and a part equivalent to an antebrachial bone proximal end are formed; an engagement recessed part 4 for engaging an articular head 2A in the state equivalent to elbow joint backward dislocation and that is provided for the antebrachial bone model 3; a first elastic body 5 for performing elastic energization in such a way as pulling a part between a first position away from the humerus model 2 distal end part to a proximal part and an elbow head part of the antebrachial bone model 3; and a second elastic body 6 for performing elastic energization in such a way as pulling a part between a second position nearer a bending side than the first position of the humerus model 2 and a position nearer an extension side than an abutment part 4 of the antebrachial bone model 3. Escape grooves 2B, 3B are formed in the humerus model 2 and the antebrachial bone model 3 so that they do not interfere with the elastic bodies 5, 6 between a normal state and the elbow joint backward dislocation state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
