Problems solved by technology
[0006] On the other hand, from the point of view of improving operability, etc., it is required to reduce the size of the grip part (diameter reduction, etc.) for the operation part, but such miniaturization of the grip part and the like will reduce the internal space of the operation part, which becomes an inducing factor. The main cause of damage to the built-in parts caused by the wire
On the other hand, it is also conceivable to provide a spacer or the like inside the operation part for isolating the built-in objects from the angle line, but the provision of such a dedicated spacer itself may become a major factor hindering the miniaturization of the grip part.

According to the present invention, the inside of an operating part 3 is divided into a first spatial section 3a and a second spatial section 3b by using stays 61a, 61b which extend in the direction of a longitudinal axis O inside the operating part 3, and a suction duct 37 of which the tip end side and the base end side are fixed to the operating part 3 such that the suction duct 37 extends in the direction of the longitudinal axis O along the stays 61a, 61b inside the operating part 3. Angle wires 23 are arranged inside the first spatial section 3a and an elongated built-in element such as a signal cable 11a or a light guide 12 is arranged inside the second spatial section 3b.
Description
technical field [0001] The present invention relates to an endoscope that bends a bending portion in conjunction with an operation of an angle wire by an operation portion. Background technique [0002] Conventionally, endoscopes for performing various inspections and treatments have been widely used in the medical and industrial fields. Among them, for example, with regard to medical endoscopes, by inserting into the body cavity of a subject such as a patient, an elongated and flexible insertion portion provided with a solid-state imaging element at the tip, even without incising the subject, It is widely used because it can obtain in-vivo images in the body cavity, and can protrude the treatment instrument from the tip of the insertion part to perform treatment if necessary. [0003] In the insertion part of such an endoscope, for example, a channel for inserting surgical instruments such as forceps, electric scalpel, and inspection probe into the body cavity of the subje...
