Embodiment Construction

[0016] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.

[0017] use Figure 1 ~ Figure 4 The first embodiment will be described.

[0018] Such as figure 1 As shown, in this embodiment, an endoscope 10 will be described as an example of an endoscope introduction device.

[0019] The endoscope (introduction device) 10 has an insertion part 12 inserted into the hole, and an operation part 14 for holding the endoscope 10 including the insertion part 12 by the user's one hand, especially the left hand, and appropriately operating the endoscope 10. , a universal cord 16 connected to a control unit (not shown) that controls the endoscope 10 .

[0020] Although not shown, the endoscope 10 internally includes a known illumination optical system for illuminating the inside of the bore and a known observation optical system for imaging and observing the inside of the bore illuminated by the illumination optical system. The e...

Abstract

The operation part has: a grip part connected to the base end of the insertion part inserted into the hole, and is held by the operator to operate the insertion part; a bending operation knob is provided on the grip part for bending the curved part of the insertion part; the protruding part, the surface between the surface on which the bending operation knob is arranged and the surface on which the palm of the operator holds the grip part abuts in the grip part On, the protruding part is formed to protrude from the holding part in the radial direction with respect to the length axis of the holding part; a push switch is arranged on the protruding part for operating the insertion part; and The inclined surface is formed on the side of the insertion part of the protrusion part apart from the push switch by a predetermined distance, and reduces the amount of protrusion in the radial direction.

Description

technical field [0001] The present invention relates to an operation part and a borehole introduction device for a borehole introduction device for introducing an insertion part into a hole. Background technique [0002] For example, in Japanese Patent Application Laid-Open No. 2004-141331 and Japanese Patent Laid-Open No. 2008-92968, in the operating part (operating part of an endoscope) disclosed in the hole introduction device, between the first holding part and the second holding part There is a step difference formed as a substantially rectangular surface (protruding surface) between them. The operation unit is grasped in a stable state by arranging the middle finger and the ring finger on the lower side of the level difference. [0003] When the user properly operates the bending operation knob, or operates various valve units, various switches, etc., it is necessary to appropriately move the hand relative to the operation part to change the grasping state. For examp...
