Description

[0002] Endoscope snake bone is mainly used to control the bending amplitude and direction of endoscope, so that it can be flexibly operated in complex surgical environment. The design inspiration of endoscope snake bone comes from snakes in nature, which is composed of multiple small segments, each of which can bend around a center point to achieve flexible navigation of endoscope in narrow or complex environment.
