Abstract:
1. A medical apparatus comprising: a bending portion that is bent via a pulled wire; a drive section that generates an amount of drive force to pull the wire; a detection section for detecting an amount of drive of the drive section; a drive force amount detection section that detects an amount of drive force of the drive section; a storage section that stores information including a correlation of the amount of drive force and the amount of drive of the drive section with respect to an amount of bending of the bending portion beforehand, the information showing an operation characteristic in which, when the bending portion is bent to a predetermined angle and subsequently bent in an opposite direction, the bending portion acts to be restored in the opposite direction; a bending amount detection section that detects the amount of bending of the bending portion based on the amount of drive and the amount of drive force, and the information stored in the storage section; a judgment section that judges the presence or absence of looseness of the wire from a detection result of the drive force amount detection section; and a correction section that corrects the amount of drive by the drive section based on a judgment result of the judgment section.
