Bio-implantable actuator and artificial joint comprising same

Abstract

The present invention relates to a bio-implantable actuator and an artificial joint including the same, and more particularly, to a bio-implantable actuator, which is capable of transmitting a movement force and reducing a load applied to a joint without limiting the degree of freedom of movement of the joint, and an artificial joint including the same. A bio-implantable actuator according to one embodiment of the present invention includes a power section generating a rotational force, a linear movement section that is connected to the power section and converts rotational movement of the power section into linear movement, and a flexible rod connected to the linear movement section. In addition, a bio-implantable actuator according to another embodiment of the present invention includes a tube having one open end and a hollow portion, a linear movement section disposed inside the tube, and a flexible rod having one end disposed inside the tube and connected to the linear movement section and another end protruding to the outside of the tube.
