IN VIVO ACTUATOR AND BONE ADJUSTMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an in vivo actuator which can be driven in vivo without surgical operation and suppress generation of erroneous operation.

SOLUTION: An electromagnetic unit 11 has an electromagnet 15 which generates magnetic force by applying induction current generated by electromagnetic induction acted from the outside of organism 102. A casing 12 holds the electromagnet 15 displaceably along a linear direction. An elastic member 13 energizes the electromagnet 15 within the casing 12. The electromagnet 15 is driven by the magnetic force acted from the outside of organism 102 to move along the straight line against the energizing force of the elastic member 13 in a condition that the magnetic force is generated by the electromagnetic induction action.
