On the other hand, in Japanese Patent Laid-Open No. 2000-23908, it is described that in the bending portion of the endoscope device, the angle manipulation lines arranged at intervals of 90° can be shifted by 45° respectively. If an attempt is made to deviate such that the positional relationship is different at 90° in the circumferential direction of the bending portion, the pulling amount of the angle operation wire and the amount of bending of the bending portion differ depending on the angle operation wire, so the operation of the operation portion The amount of bending and the bending amount of the bending part vary depending on the bending direction, which may result in a decrease in the operating feeling

Provided is an operatin mechianism, endoscope apparatus, and guide catheter that enable more intuitive operation of a cuved portion than a rotation input portion, by the use of a tilt input portion. The endoscope apparatus comprises: a rotation input portion provided in an operation section and to which a first drive for for curved operation of a curved portion is input; an operation wire connected to the rotation input portion and the curpved portion and which transmits the first drive force to the curved portion by being pulled by the rotation input portion; a tilt input portion provided in the operation section and to which a second drive force for curved operation of the curved portion is input; and a second transmission means connected to the tilt input portion and the rotation input portion and which transmits the second drive force from the tilt input portion to the rotation input portion. The operation wire transmits the second drive force transmitted from the tilt input unit by the second transmission means to the curved portion.
Description
technical field [0001] The invention relates to an operating mechanism, an endoscope device, medical equipment and a guiding catheter. [0002] This application claims priority from 61 / 328,814, filed April 28, 2010 in the United States, and 61 / 353,805, filed June 11, 2010 in the United States, the contents of which are incorporated herein by reference. Background technique [0003] Conventionally, an endoscope apparatus has been used for observing and treating a site to be treated in a body cavity and the like. As an endoscope device, there is known an endoscope device in which a flexible elongated insertion portion inserted into a body cavity is connected to an operation portion for operating the insertion portion (for example, Patent Document 1). In addition, Patent Document 2 discloses an endoscope operating unit that allows an operator who operates an endoscope device to operate an endoscope treatment tool and an endoscope device without an assistant. [0004] In addit...
