Abstract
A curving control device to which an electrically-controlled endoscope is connected has a main CPU for primarily performing curving driving control, and a monitoring CPU for monitoring whether the operating state relating to curving actions is normal or abnormal. In the event of detecting an abnormality from the monitoring CPU, the curving control device also performs processing for handling the occurrence of the abnormality, such as outputting an emergency stop through an interlock via the main CPU, turning the main power and the like of a servo driver OFF.
Claims16
An electrically-operated curving control device comprising:
- curving driving control means for controlling a curving driving mechanism for electrically performing curving driving of a curving portion of an endoscope;
- monitoring means for monitoring the state of electrically performing curving driving control of the curving portion, the monitoring means being configured to monitor whether the curving control state is normal or abnormal, and output a monitoring result to the curving driving control means;
- detecting means for detecting that the curving driving mechanism is in an abnormal state and making notification of error data when the curving driving mechanism is in the abnormal state;
- and
- processing means connected to the curving driving control means, the monitoring means and the detecting means, the processing means being configured to be able to stop the driving operation of the curving driving mechanism by receiving a command from the curving driving control means and causing the curving driving mechanism to operate in an operation state corresponding to the abnormal state of the curving driving mechanism when the error data is received from the detecting means.
