Abstract
An electric bending endoscope comprises a bending portion arranged to an inserting portion, a bending driving unit and a buffering member. The bending driving unit bends the bending portion, and includes a motor, a first unit and a second unit. The motor generates driving force for bending the bending portion. The first unit holds the motor. The second unit includes a driving force transmitting member. The buffering member connects the first unit to an outer member of the inserting portion, a connecting code and a switch. The buffering member absorbs external force generated during the operation of the electric bending endoscope.
Claims12
An electric bending endoscope comprising:
- a bending portion arranged to an inserting portion;
- a bending driving unit which bends the bending portion, the bending driving unit including a motor which generates driving force for bending the bending portion, a first unit which holds the motor, and a second unit which includes a driving force transmitting member that transmits the driving force of the motor to bend the bending portion by the driving force of the motor;
- and
- a buffering member which connects the first unit to an outer member of the inserting portion, a connecting code, and a switch arranged to the electric bending endoscope, the buffering member absorbing external force generated during the operation of the electric bending endoscope.
An electric bending endoscope comprising bending driving unit which bends a bending portion arranged to an edge side of an inserting portion thereof,
- wherein the bending driving unit comprises at least two detachable units of:
- a frame unit which holds a motor as a driving source for bending the bending portion;
- and
- a bending and stretch mechanism unit which has a driving force transmitting member for bending the bending portion by using rotation driving force from the motor, and
- wherein an outer member of the inserting portion, a universal code, and necessary switches for operating the operations of the electric bending endoscope are connected to the frame unit via an mediating member.
An electric bending endoscope comprising:
- a bending portion arranged to an inserting portion;
- and
- bending driving means which bends the bending portion,
- wherein the bending driving means comprises:
- driving force generating means which generates driving force for bending the bending portion;
- a first unit which holds the driving force generating means;
- a second unit which has a driving force transmitting member which transmits the driving force of the driving force generating means and bends the bending portion by the driving force of the driving force generating means, and
- wherein the first unit is connected to an outer member of the inserting portion, a connecting code, and operating means arranged to the electric bending endoscope so as to absorb external force generated during the operation of the electric bending endoscope.
