INTRODUCING APPARATUS

摘要

The introducing apparatus comprises the operating section, which is easy to grip and easy to operate, mounted therein by providing the dial of the operation element to perform a bending operation of the bending section and a part of the rotary mechanism alone while avoiding an operation range of the operating section for fingers of a gripping hand.

主权项

1. An introducing apparatus comprising:
a bending section provided on a distal end side of an inserting section which is inserted into a lumen; an electric bending drive mechanism having an electric drive source to bend the bending section; a rotary knob which instructs the electric bending drive mechanism to perform a bending operation so that the bending section bends in a first direction orthogonal to an inserting direction thereof; an operation element comprising: a dial which instructs the electric bending drive mechanism to perform a bending operation so that the bending section bends in a second direction orthogonal to both the inserting direction and the first direction and which is exposed to the outside; a rotary mechanism which holds the dial to be rotatable on a rotary shaft; a transmission mechanism which transmits a rotation amount of the dial along an axis direction deviating from an axis of the rotary shaft; and a detecting section which outputs an output value according to the rotation amount transmitted by the transmission mechanism; and an operating section which has a rectangular housing and accommodates the operation element therein in such a manner that the rotary knob is arranged on a front surface thereof, a proximal end portion of the inserting section is arranged on a bottom surface continuous from the front surface, a hollow protruding portion is formed on a side surface continuous from the front surface to protrude at a position closer to the proximal end portion of the inserting section than a rotation center position of the rotary knob as seen from the bottom surface, the rotary mechanism alone is arranged in the hollow of the protruding portion, and the detecting section is arranged in the housing.
