Abstract

An endoscope comprises: an insertion section provided with a bendable section on the distal end side thereof, the bendable section being bendable at least in the vertical direction; an operating section to which the proximal end of the insertion section is connected; a pull-wire having a first end and a second end, the first end being connected to the insertion section and being pulled to bend the bendable section; a fixation member affixed to the second end of the pull-wire; a holding member for holding the affixation member; and a pulley provided within the operating section so that the pulley can pivot and having an arrangement section in which the holding member is arranged.

Description

technical field [0001] The present invention relates to an endoscope having a bending lever for pulling / loosening a bending wire on an operating portion. Background technique [0002] Endoscopes capable of observation and the like by inserting an elongated insertion portion into a subject are widely used. Some endoscopes include a type in which a bending portion is provided on the distal end side of an insertion portion. The bending part is generally configured to perform a bending operation by pulling or loosening the bending wire by turning a bending lever provided on the operating part, for example, as a bending operation device. [0003] For example, the endoscope device disclosed in Japanese Patent Application Laid-Open No. 2005-218569 shows a bending wire configured by connecting a pulling wire on one side to a pulling wire on the other side by a wire connecting mechanism. The wire connection mechanism is composed of an external threaded joint fixedly provided with t...
