ENDOSCOPE SYSTEM

摘要

An endoscope system of the present invention includes a control part has a computation part which computes the radius of curvature of the central axis of the instrument channel when the input signal is received and, may generate the first driving signal according to a result of the computation part computing the radius of curvature so that a treatment instrument at which a rigid part is provided to be easily inserted into a channel while a view of an observation part is limited from deviating from an object to be treated, even when a radius of curvature of a bending part is small while the bending part is bent.

1. An endoscope system comprising:
an insertion part having flexibility and an instrument channel into which a medical instrument is insertable formed therein; a flexible tube part provided at a proximal end portion of the insertion part; a bending part provided at a distal end portion of the insertion part and bendable with respect to a distal end portion of the flexible tube part; a tubular body in which an insertion part channel into which the flexible tube part is insertable is formed and provided to be movable along a longitudinal axis of the flexible tube part with respect to the flexible tube part; a first driving part configured to operate the bending part to be bent with respect to the distal end portion of the flexible tube part; a second driving part provided at a distal end portion of the tubular body to drive the flexible tube part inserted into the insertion part channel toward a proximal end portion with respect to the tubular body; and a control part configured to generate a first driving signal which drives the first driving part so that the bending part is operated to be bent in a direction in which a radius of curvature of a central axis of the instrument channel enlarges and a second driving signal which drives the second driving part according to a first driving signal which drives the first driving part, and configured to perform control for transmitting the first driving signal to the first driving part and transmitting the second driving signal to the second driving part.
