The present invention provides a bending device which is capable of easily controlling a bending motion with superior controllability. A portion of an elastic tube body () opposite a portion in which a non-stretching body () is fixed inflates in a circumferential direction of the elastic tube body () in response to increase in an internal pressure of the elastic tube body (), and an elastic tube (P) bends in a step-wise angle corresponding to the number of layers of a multi-layer structure. The portion of the elastic tube body () in which the non-stretching body () is fixed is thicker than the remaining portion of the elastic tube body ().

Bending device, control device, and medical instrument

There is provided a medical device whose occupied space is reduced. According to an aspect of the present invention, a medical device () adjusts a position of a medical instrument including a rod-like insertion unit () for being inserted into a body. The medical device includes an ultrasonic actuator that holds the insertion unit of the medical instrument, and that displaces or rotates the insertion unit with respect to the ultrasonic actuator, and an actuator fixing unit (and) that fixes a position of the ultrasonic actuator to a surgical site.
