Bent portion of endoscope and endoscope

Abstract

The invention provides a bent portion of an endoscope and the endoscope. The bent portion of the endoscope includes a plurality of bent blocks connected end to end. Every two adjacent bent blocks arerotatably connected through a connecting portion, and the connecting portion comprises a groove and a protrusion. The protrusions are rotatably accommodated in the grooves, the end faces of the bent blocks are respectively provided with abutting surfaces on the two sides of the connecting portions, the protrusions relatively rotate to the maximum angle in the grooves, the abutting surfaces of every two adjacent bent blocks abut against each other to enable the two bent blocks to be at the maximum bending angle, the heights of the multiple bent blocks are identical, the multiple bent blocks aredivided into multiple bent block groups in the extending direction of the bent portions, and the maximum bending angles of the bent block groups close to the front ends of the bent portions are the maximum. The bent portion of the endoscope and the front end of the endoscope are large in bending angle, thereby providing convenience for the endoscope to be extended in.

Description

technical field [0001] The invention relates to an endoscope component, in particular to an endoscope bending part and the endoscope. Background technique [0002] The endoscope is a widely used medical and industrial inspection device, and its bending part is realized by the method of pulling a plurality of snake bone joints connected to each other by a steel wire rope to change the direction of bending. The steel wire rope is connected to the inner side of the snake bone joint through a connecting structure, so as to realize traction to the snake bone joint. Moreover, the joints of adjacent snake bones are hinged to each other, so as to realize relative rotation. [0003] In order to ensure the overall strength of the curved portion of the endoscope in traditional endoscopes, the bending angle of the curved portion is usually designed to be small. However, in the actual medical application process, due to the complex and changeable use environment, when the endoscope enc...

AI Technical Summary

Problems solved by technology

However, in the actual medical application process, due to the complex and changeable use environment, when the endoscope encounters a cavity with a large bending angle, the bending angle of the front end of the endoscope often cannot reach a large bending angle. Thus affecting the use of the entire endoscope
