External mechanism for endoscope, and endoscope apparatus

An endoscope includes an insertion portion, an operation portion, a power transmission unit, a power relay unit, a power generation unit configured to apply power to the power relay unit in a second power transmission shaft direction which is non-parallel to a first power transmission shaft direction, an elastic member configured to perform either one of urging the power relay unit against the power generation unit or urging the power generation unit against the power relay unit, and a cable configured to extend from the operation portion in the second power transmission shaft direction which is a direction different from a longitudinal direction, wherein the power generation device is attached such that the power generation device is disposed to extend in an extending direction of the cable after being mounted.

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.

An external mechanism for endoscope includes: an abutment surface that is a first surface configured to cover a knob arranging surface at which a second bending operation knob is arranged in an operation portion of an endoscope; a wheel configured to engage with the second bending operation knob arranged at the knob arranging surface; a motor configured to generate a driving force for rotating the wheel; a housing case that houses the wheel and the motor; a case attaching/detaching and fixing section for detachably attaching the housing case to the operation portion of the endoscope; and a locking member provided at the housing case and configured to be locked on the knob arranging surface of the endoscope and a large-diameter portion end face adjacent to the knob arranging surface in the operation portion of the endoscope.

External mechanism for endoscope and endoscope apparatus

A first housing region A which is provided in the operation portion and in which a bending drive mechanism is housed, a second housing region B which is provided in the operation section and in which a flexible member is housed, and a third housing region C which is provided in the operation portion and in which an electric part is housed are provided, the first housing region A and the second housing region B are located to be lined up in an orthogonal direction Q, and the third housing region C is located to be adjacent to both of the first housing region A and the second housing region B so that a first boundary line Tis orthogonal to a second boundary line T

In the present invention, there are provided a movement member which includes an engaging section, which is engaged with an intermediate part of an operation shaft of a joystick device, and operates as one body with the operation shaft at a time of performing an inclining operation of the operation shaft, and a damper case in which the movement member is movably inserted, and which holds a viscous fluid which increases a sliding resistance of the movement member when the movement member is moved. Thereby, a desired operational sensation can be always obtained, and a stable bending operation can be performed.

Operation device and bending operation device of endoscope

A socket sectionfor providing a first light guideis supported movably in an endoscope main body, and a plug sectionfor fixing a second light guideis disposed in an endoscope insertion section. The socket sectionis configured to move freely in an insertion direction of the endoscope insertion sectionand to a direction orthogonal with respect to the insertion direction. Furthermore, an attachment-detachment-detecting switchis disposed in the endoscope main bodyso as to detect that the endoscope insertion sectionhas been separated from the endoscope main bodybefore the plug sectionis freely detached from the socket section. By this configuration, it is possible to attach the endoscope insertion section from the endoscope main body and detach them easily and reliably, in particular, to reduce loss of light caused by the attachment and the detachment.

Endoscope and endoscope system

An endoscopeincludes an insertion bodyequipped with a potentiometerfor detecting a bending state of a bending portionB which is allowed to be bent and inserted into a subject and an electric connectorfor outputting an electric signal as a detection result of the potentiometer, and a motor unitdetachable with respect to the insertion bodyvia an attachment/detachment portion, which is equipped with an electric motorfor bending the bending portionB.

Power driven bending endoscope device with detachable insertion portion

An action display system includes an action instruction signal generating portion configured to generate an action instruction signal for instructing an action of an acting portion in response to an input to an input portion, an action control portion configured to control a drive portion such that the acting portion acts in accordance with the action instruction signal, the action control portion switchable between a regular mode to enable an action of the acting portion with the first and second degrees of freedom and an action disabled mode to disable an action of the acting portion with one degree of freedom, an image obtaining portion configured to obtain an image associated with an action state of the acting portion, and a display portion configured to display an index associated with the regular mode and the action disabled mode of the action control portion together with the image.

Action display system and endoscope system

A direction of movement, an insertion amount and an insertion force amount at a time when an insertion section of an endoscope is inserted in a large intestine, which is an object of an inspection, are detected by detection unit. The direction of movement, the insertion amount and the insertion force amount of the insertion section are displayed on a display device which is separably disposed. Thereby, a high-precision insertion operation can simply and easily be realized, and a handling operability is improved.

Endoscope apparatus with advancement/retreat detection means

An electric bending endoscope includes an elongate insertion portion provided with a bending portion, a drive unit, and an operation unit, wherein the drive unit and the operation unit respectively include a drive unit side electric contact portion and an operation unit side electric contact portion configured to be coupled to and separated from each other by moving the drive unit and the operation unit close to and apart from each other in a coupling and separation axial direction, and the drive unit and the operation unit includes a lock mechanism configured to lock and unlock the drive unit and the operation unit to and from each other with respect to the coupling and separating axial direction.
