ENDOSCOPE, AND TREATMENT INSTRUMENT FOR ENDOSCOPE

摘要

A medical instrument system includes: an elongated member that has a longitudinal axis and an inner space in a direction of a longitudinal axis, and is formed in the direction of the longitudinal axis; an insertion section that is arranged at the inner space so as to freely move in the direction of the longitudinal axis and has a bending section capable of being bent; a manipulation section configured to manipulate the bending section; a first manipulation member that is connected to the manipulation section and transmits a driving force of the bending section in accordance with the manipulation by the manipulation section; a second manipulation member that is connected to the bending section and is arranged in the direction of a longitudinal axis; a connecting section capable of detachably connecting the first manipulation member and the second manipulation member; and a switching mechanism that switches between a connection state in which the first manipulation member and the second manipulation member are connected by the connecting section and a release state in which a connection of the first manipulation member and the second manipulation member is released, in accordance with a relative movement between the elongated member and the insertion section.
