Endoscope system
First Claim
1. An endoscope system comprising:
- an endoscope having a channel;
an insertion-section flexibly inserted into the channel;
a treating section, disposed at a distal end of the insertion-section, for treating a target section;
a driving-section, making contact with the insertion-section, for driving the insertion-section along predetermined directions; and
a pivoting section for directing the driving-section toward a first direction or a second direction, whereinthe first direction is a direction in which the insertion-section is driven along an axial line of the insertion-section,the second direction is a direction in which the insertion-section rotates around the axial line,the driving-section has a plurality of rollers making contact with the insertion-section, andthe pivoting section is configured to allow rotation of the plurality of rollers around an axis which is orthogonal to the axial line and to an axial line of the plurality of rollers.

Abstract
An endoscope system has an driving-section for driving an insertion-section having an instrument. The driving-section is supported by a pivoting section rotatively. The driving-section has two rollers facing each other. The insertion-section is disposed between the rollers. The insertion-section is extended or retracted by rotating the rollers if the rollers are disposed with respect to the extension/retraction direction. If the pivoting section is pivoted to be orthogonal to the extension/retraction direction, the insertion-section rotates around its axial line by the rotation of the rollers. By doing this, it is possible to rotate the instrument easily in the endoscope system for extending/retracting the instrument by electric power.
