OPERATION DEVICE FOR INTO-BORE INTRODUCTION DEVICE, AND INTO-BORE INTRODUCTION DEVICE

摘要

An operation device for an into-bore introduction device, includes: a projecting portion formed to project from a grasping section in a radial direction to a longitudinal axis of the grasping section, in a surface between a surface on which a bending operation knob is disposed and a surface on which operator's palm abuts to grasp the grasping section, in the grasping section; a pressing switch disposed on the projecting portion; and an inclined surface formed distantly by as much as a predetermined distance from the pressing switch, and in which an amount of the inclined surface to project outside in the radial direction is decreased on an insertion section side of the projecting portion.

主权项

1. An operation device for an into-bore introduction device, comprising:
a grasping section that is connected to a proximal portion of an insertion section to be inserted into a bore, and is to be grasped by an operator to operate the insertion section; a bending operation knob that is disposed on the grasping section and that bends a bending portion of the insertion section; a projecting portion that is formed to project from the grasping section in a radial direction to a longitudinal axis of the grasping section, in a surface between a surface on which the bending operation knob is disposed and a surface on which operator's palm abuts to grasp the grasping section, in the grasping section, the projecting portion including a projection surface on which a finger of the operator's hand to grasp the grasping section abuts on a side of the projecting portion close to the insertion section; a pressing switch that is disposed on the projecting portion and that operates the insertion section; and an inclined surface that is formed at a position of the projecting surface of the projecting portion adjacent to the surface on which the bending operation knob is disposed and a position of an equal distance from the pressing switch toward a side close to the insertion section along the longitudinal axis, to the shortest distance defined between an edge portion in the direction peripheral to the longitudinal axis and the pressing switch on a surface between the surface on which the bending operation knob is disposed and the surface on which the palm abuts, and by which the finger of the hand of the operator is prevented from interfering with the projecting portion when the bending operation knob is operated with the operator's finger operable with the pressing switch.
