Endoscope snake bone and endoscope

The invention discloses an endoscope snake bone and an endoscope, the endoscope snake bone comprises a plurality of bone joint pieces which are connected in sequence, the end part of each bone joint piece is provided with a rotary buckle, two adjacent bone joint pieces are rotatably connected through the rotary buckles, the end part of each bone joint piece is also provided with a side edge groove and/or a side wing, and in two adjacent bone joint pieces, the side wing of one joint piece is matched in the side edge groove of the other joint piece. In two adjacent joint pieces, the top wall of the side wing of one joint piece and the bottom wall of the side edge groove of the other joint piece are located on the two sides of the horizontal plane passing through the rotation center of the rotary buckle respectively. When the snake bone of the endoscope is bent, the offset of the side wings is small, the occupation of the internal space of the snake bone of the endoscope is reduced, the friction between the snak
