Title: ENDOSCOPE AND TREATMENT TOOL ERECTING MECHANISM
Abstract:
Provided are an endoscope and a treatment tool erecting mechanism with which it is possible to reduce the size of a distal end body while maintaining satisfactory operability of an erecting mount. In a distal end body 30 of this endoscope, an erecting lever 82 is coupled to an erecting mount 60 by way of a rotating shaft, and the erecting lever 82 is caused to rotate about the rotating shaft by being pushed and pulled by an operating wire, thereby causing the erecting mount 60 to rotate. The erecting lever 82 comprises a first arm portion 83 provided extending from the rotating shaft, and a second arm portion 84 provided extending in a different direction to the first arm portion 83, and wasted space on the base end side of the distal end body 30 is reduced by virtue of the shape of the erecting lever 82.
