Abstract

Endoscopy is a detection instrument that integrates traditional optics, human engineering, precision machinery, modern electronics, mathematics, and software[1]. Based on whether the shaft can change direction, endoscopes are classified into rigid scopes and flexible scopes. Snake bone is an important component of the flexible scope that enables bending, and its performance significantly impacts the quality of the endoscope. Snake bones include one-piece snake bones and multisegmented snake bones, and one-piece snake bones are simpler and more reliable than multi-segmented snake bones. In this paper, a three-dimensional model of a one-piece snake bone is designed, and the flexural performance of the snake bone is studied by finite element simulation. During the simulation, the material properties of the snake bone are defined, and the actual working state of the snake bone is simulated by applying load. The simulation results of different parameters of the snake bone were compared, and the key parameters of the snake bone structure were optimized.
