MEDICAL SYSTEM AND ENDOSCOPIC SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a medical system which can perform the control of two or more movement components such as a sheath section or an operation tube section with a movement mechanism.

SOLUTION: An endoscopic system 1 is provided with: a treatment instrument 20 equipped with a sheath section 21 comprising an outer sheath 22 and an inner sheath 23 which is interpolated in the outer sheath 22 and is longer than the outer sheath 22; an apparatus 40 for inserting and drawing insertion section, which transmits driving force to the outer sheath 22 or an inner sheath 23, composing the sheath section 21 of the treatment instrument 20, and moves at least one of the outer sheath 22 or the inner sheath 23; and a contact ring 25a which is prepared in the inner sheath 23 and prevents the driving force of the apparatus 40 from being transmitted to the outer sheath 22 when this inner sheath 23 is moved by a predetermined distance.
