Abstract
An external mechanism for an endoscope includes: a bending wheel configured to engage with a second UD knob of a second bending operation device provided in an operation portion of an endoscope; a motor portion configured to generate a driving force for rotating the bending wheel; a housing case housing the bending wheel and the motor portion and detachably attached to the operation portion, and an operation switch arranged outside the housing case and configured to output a control signal to the motor portion due to the operating element being operated, in which the operation switch is pivotally supported by the rotation shaft and rotates with respect to the housing case.
Claims12
An external mechanism, comprising:
- an engagement member configured to matingly engage with a bending operation knob of a bending operation device provided in an operation portion of an endoscope;
- a driving motor configured to generate a driving force for rotating the engagement member;
- a housing case housing the engagement member and the driving motor, the housing case being configured to be detachably attached to the operation portion;
- an operation switch rotatably connected to the housing case and configured to output a control signal to the driving motor, and
- a rotation shaft, wherein the operation switch is pivotally supported by the rotation shaft such that the operation switch rotates with respect to the housing case.
An external mechanism comprising:
- an engagement member configured to matingly engage with a bending operation knob of a bending operation device provided in an operation portion of an endoscope;
- a driving motor configured to generate a driving force for rotating the engagement member;
- a housing case housing the engagement member and the driving motor, the housing case being configured to be detachably attached to the operation portion;
- and
- an operation switch connected to the housing case and configured to output a control signal to the driving motor, wherein
- the operation switch includes a dummy switch, and
- the dummy switch being disposed to communicate with a remote switch provided in the operation portion of the endoscope such that activation of the dummy switch activates the remote switch.
An endoscope apparatus comprising:
- an endoscope comprising:
- an insertion portion having a bending portion;
- and
- an operation knob configured to operate the bending portion;
- and
- an external mechanism comprising:
- an engagement member configured to matingly engage with the operation knob;
- a driving motor configured to generate a driving force for rotating the engagement member;
- a housing case housing the engagement member and the driving motor, the housing case being configured to be detachably attached to the operation knob;
- an operation switch rotatably connected to the housing case and configured to output a control signal to the driving motor, and
- a rotation shaft, wherein the operation switch is pivotally supported by the rotation shaft such that the operation switch rotates with respect to the housing case.
