An in-vivo monitoring camera system includes an image capturing portion (camera unit) that is capable of being introduced into a body, a support tube () that has a connection portion (trocar connection portion) with a tubular tool (trocar) which is capable of being introduced into the body on one end side and has a joining portion (protrusion type joining portion) to the image capturing portion on another end side, a cable (camera-side cable) that is connected with the image capturing portion and passes through the support tube, and a control system that is electrically connected with the cable and includes at least a display device ().

In-vivo monitoring camera system

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 ().
