Patent number: 11478123Abstract: A control apparatus controls an operation of a self-propelled mechanism of an endoscope. The control apparatus includes a drive circuit that outputs a motor current, a motor current detection circuit that acquires a value relating to magnitude of the motor current as a detection value, a storage circuit that stores a limit value relating to the detection value, and a control circuit that performs an operation as a first controller that controls the drive circuit so as to stop the motor when it is determined that the detection value exceeds a value relating to the limit value, and performs an operation as a second controller that controls the drive circuit so as to stop the motor when it is determined that the detection value exceeds the value relating to the limit value.Type: GrantFiled: January 8, 2020Date of Patent: October 25, 2022Assignee: OLYMPUS CORPORATIONInventors: Takashi Suzuki, Fumiyuki Onoda, Takashi Yamashita, Yasuaki Natori, Yoshitaka Umemoto, Toshihiro Kumagai, Takuro Onda

Patent number: 10978970Abstract: An apparatus includes a rotation body, a motor, a drive controller, a rotating speed detector, a rotation error determination circuit, and a filter. The rotation body is provided on an outer peripheral surface of an elongated insertion section and configured to be rotatable around a longitudinal axis. The motor rotates the rotation body. The drive controller controls driving of the motor. The rotating speed detector detects a rotating speed of the motor based on an encoder signal output from an encoder. The rotation error determination circuit determines an error in rotation of the rotation body based on the detected rotating speed. The filter passes, as the encoder signal, only a signal having a frequency, outside a frequency band of a high-frequency signal of a high-frequency treatment instrument, of signals input to the rotating speed detector.Type: GrantFiled: November 27, 2019Date of Patent: April 13, 2021Assignee: OLYMPUS CORPORATIONInventors: Yoshitaka Umemoto, Takashi Suzuki, Toshihiro Kumagai, Takuro Onda
