Title:
STRUCTURE FOR STABILIZING MODEL OF LUMBAR VERTEBRA OF HUMAN BODY AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP3917414
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To obtain stable characteristics of fluctuations in pressure in measuring a static load and consequently to stably measure the pressure generated in a pulpous nuclear member which is an artificial pulpous nucleus.
SOLUTION: A lumbar vertebra forming body 10 which has a cylindrical shape, is aligned in central axes and forms an area having an easy tendency to the occurrence of an intervertebral disk hernia by fitting an upper body member 17, fourth lumbar vertebra members 11 and 12, fiber ring member 24, fifth lumbar vertebra members 14 and 15 and a lower body member 15 from above is provided with relief segments GU in slender segments 17N and 18N in such a manner that the external form dimensions of an abdominal muscle section 19 of the back to tighten the slender segments 17N and 18N by elastic materials at the circumference of the central segment of the lumbar vertebra forming body 10 are within the respective external form dimensions of the upper body member 17 and the lower body member 15 when the maximum load is exerted to these segments. The central axis of the fourth lumbar vertebra member 12 is provided with a through-port 34 and the pulpous nuclear member 16 is made to flow over together with the fluid intruding therein from the through-port 34 when the through-port is fitted to the fiber ring section 13 internally filled with the pulpous nuclear member 16.
