ELECTRICALLY BENDING ENDOSCOPE

摘要

An electrical bending endoscope includes: a driving-force transmitting mechanism that transmits the driving force for bending a bending portion (12b); a motor that supplies the driving force to the driving-force transmitting mechanism; a driving-force interrupting mechanism that is arranged to a transmitting line of the driving force transmitted from the motor to the bending portion (12b) and interrupts the transmission of the driving force; and a switching operating member (23x) that operates the interrupt of the driving-force interrupting mechanism. The electrical bending endoscope further includes a click mechanism including a click spring (24) that generates the inconstant amount of change in force upon operating the switching operating member (23x) and click concave portions (22d and 22e) and the state of the switching operating member (23x) is sensed by an operator, thereby preventing the erroneous operation.
