Abstract: An endoscope device includes a flexible insertion portion; a flexible tube portion; a first bending portion; a second bending portion; an observation portion; a first drive portion bending the first bending portion; a second drive portion bending the second bending portion; a position detection portion detecting a position of a rigid distal end portion of a medical instrument; first and second bending detection portions detecting radii of curvature of axes of channels formed in the first and second bending portions and directions in which the channels are bent when an input signal generated by the position detection portion is received, respectively; and a control portion configured to control generating a second drive signal driving the second drive portion based on a first drive signal driving the first drive portion, and sending the second drive signal to the second drive portion while sending the first drive signal.

Abstract: A suture needle has: a flexible elongated shaft member; a passing mechanism for passing a suture needle between two gripping members, wherein the passing mechanism has fitting hole portions that are provided in the respective gripping members and that hold the suture needle in a fitting manner, a holding member movable in a direction intersecting the axis of each fitting hole portion and having a pressing surface which can press an outer circumferential surface of the suture needle held in the fitting hole portion, and a tensile-force-transmitting member coupled with the holding member and which can move along the longitudinal axis of the elongated shaft member, wherein the outer circumferential surface of the suture needle is pressed by the pressing surface against the inner circumferential surface of the fitting hole portion by the motion of the tensile-force-transmitting member.
