Snake bone machining method

The invention relates to the technical fields of medical apparatus and instruments, and specifically discloses a snake bone machining method. A metal pipe is machined into a plurality of separated metal pipe units through a hollowing-out blanking machining mode, due to the fact that the end faces, subjected to hollowing-out, of every two adjacent metal pipe units are provided with two mutually matched pivoting structures, and a radial separation-resistant structure and an axial separation-resistant structure are arranged between the pivoting structures, so that a snake bone machined through the machining method is formed in one effort, and assembling techniques are not needed; and thus, the technique is simple, the production efficiency is improved, the production cost is reduced, and the snake bone structure reliability is better.
