The helical tunneling device is a tool for tunneling along helical or spiral paths. Further, the tool may be used as a fixation device along helical/spiral paths, for connecting different surfaces or joints. Furthermore, the device includes associated instrumentation needed for creating such a helical path. In one embodiment, the device uses a woven flexible shaft in a helical tube to transmit rotational motion to a cutting tool. The helical tube may then be rotated independently to advance the cutting tool along a helical trajectory. In another embodiment, the device may advance helically into the created tunnel to engage, couple, and fix the relative positions of both bodies through which a continuous helical tunnel is created. Thus, the helical tunneling device is a simple and efficient tool that may be beneficial for wood working, orthopedics, metal manufacturing etc.
