Electric bending endoscope
First Claim
1. An electric bending endoscope comprising:
- an inserting portion having a bending portion which is inserted in a subject;
an operation wire which is inserted in the inserting portion for bending the bending portion;
a motor for supplying a driving force to the operation wire for bending the bending portion;
a first unit for holding the motor;
a driving force transmitting member which transmits the driving force supplied from the motor to the operation wire in order to bend the bending portion, the driving force transmitting member being connected to the operation wire via a connecting portion;
a second unit for holding the driving force transmitting member;
a first connecting member for connecting the first unit and the second unit so that the driving force of the motor maybe transmitted to the driving force transmitting member; and
a second connecting member for connecting the second unit and the inserting portion so that the bending portion many be bent by the driving force transmitted from the driving force transmitting member.

Abstract
An electric bending endoscope includes a bending portion arranged to an inserting portion and a bending driving unit which bends the bending portion. In the electric bending endoscope, the bending driving unit includes a motor which generates driving force for bending the bending portion, a first unit which holds the motor, a driving force transmitting member which transmits the driving force of the motor, and a second unit which bends the bending portion by the driving force of the motor. The electric bending endoscope further includes a first holding member which detachably supports, to the first unit, a rotating shaft arranged to the driving force transmitting member of the second unit.
