In actual clinical operations, surgeons mainly rely on experience and hand feel to drill or insert needles, which has great variability. If any dimension is not well controlled, it is difficult to accurately determine the needle point. Therefore, a guide is used to guide the drill bit or needle to ensure an accurate needle point.

[0003] The guide is mainly composed of a guide tube and a positioning point located on the axis of the guide tube. The guide tube guides the drill bit and the needle. The needle exit point is the position indicated by the positioning point. Therefore, it is necessary to ensure the high coaxiality of the guide tube and the positioning point.
