Problems solved by technology

[0007] However, conventional endoscopes have the following problem: when the bending part is bent by the pulling of the wire, it is bent from the proximal end direction of the hand side as the bending part, and it is difficult to insert the insertion part into the complicated tube of the subject. Cavity etc.

Abstract

This endoscope insertion part (2) is provided with: a first bending part (7a) provided at the tip side; a second bending part (7b) which is connected to the base end of the first bending part (7a), and which is provided with a higher bending rigidity than the first bending part (7a); a tubular member (40) in which a tip-side first tubular region (40a) provided inside the first bending part (7a) is provided with a shape memory, and has a bending habit in a prescribed direction imparted thereto, said tubular member (40) being provided with a base-end-side second tubular region (40b) provided inside the second bending part (7b); a first wire (44) which enables movement of the first tubular region (40a), and independently bends only the first bending part; and second wires (47, 48) which enable movement of the second tubular region (40b), and independently bend only the second bending part (7b).

Description

technical field [0001] The present invention relates to an endoscope insertion unit and an endoscope having a bending portion that is bent by manual manipulation. Background technique [0002] In recent years, medical equipment (such as an endoscope) inserted into a subject has been widely used in the medical and industrial fields. [0003] In particular, the endoscope used in the medical field can observe the organs in the body cavity by inserting the elongated insertion part into the body cavity of the subject, or use the treatment instrument inserted into the endoscope as needed. Various treatments are performed through the treatment instrument inserted into the channel. [0004] It is known that such a conventional endoscope is provided with a bendable portion in an insertion portion thereof in order to improve insertion into a subject. [0005] The bending portion provided in the insertion portion of a conventional endoscope is formed by rotatably connecting a plurali...
