Endoscope bend

The utility model provides an endoscope bending part which comprises a connecting line and a plurality of snake bone joints, and the snake bone joints are sequentially hinged to form a bending unit. A limiting connecting surface is arranged on the snake bone joint; and the connecting lines are used for connecting the snake bone joints through the limiting connecting surfaces. The utility model has the advantages of simple processing technology and high reliability, and maximizes the utilization of the space of the inner cavity. And through a centripetal cutting machining mode, the snake bone joint is connected through one connecting line, and the space of the inner cavity is further released. 本实用新型提供了一种内窥镜弯曲部，包括连接线和多个蛇骨关节，多个蛇骨关节依次铰接形成弯曲单元；蛇骨关节上设置有限位连接面；连接线通过限位连接面对多个蛇骨关节进行连接。本实用新型加工工艺简单，可靠性高实现了内腔空间利用最大化。通过向心切割加工的方式，实现了一根连接线对蛇骨关节的连接，进一步释放内腔空间。
