Abstract: A monitoring system includes an endoscope shape detection apparatus configured to detect a shape of an insertion section of an endoscope and a movement detection apparatus configured to detect a movement of a hand that operates the endoscope.

Abstract: 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.

Abstract: 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.

Abstract: A pulling apparatus includes an input portion configured to be operated, a braking portion configured to apply a braking force to the input portion to generate a resistance force against to an operation to the input portion, a pulling portion configured to pull a pulling member, a pulling order generation portion configured to generate a control order signal to the pulling portion such that the pulling member is pulled by the pulling portion in accordance with an operation to the input portion, a pulling amount detecting portion configured to detect pulling amount of the pulling member, a pulling amount increase and decrease determination portion configured to determine an increase and decrease in the pulling amount detected by the pulling amount detecting portion, and a braking control portion configured to control the braking portion in accordance with a determination result obtained by the pulling amount increase and decrease determination portion.

Abstract: A motor-driven bending endoscope includes a removal restriction mechanism which restricts removal of a trackball from a trackball mounting portion, and an operation section engaging portion which detachably engages an attachment/detachment portion with an operation section attachment portion at a time of coupling between the operation section attachment portion and the attachment/detachment portion when an operation section unit is attached to the operation section attachment portion. The operation section engaging portion and the removal restriction mechanism are interlockingly driven by an interlock drive mechanism. Thereby, there is provided a motor-driven bending endoscope which can reduce fatigue of the right hand at a time of performing a twisting operation of an insertion section, improve the recognizability of the up-and-down direction at a time of inserting the insertion section, and enhance the operational work efficiency.
