The application relates to a novel curved drilling guide, which relates to the field of medical devices, including an alloy with shape memory effect, a guide drill for reaming a hole to construct a bone tunnel, and a cannula for guiding the guide needle; the The guide needle is slidably coaxially threaded through the guide drill, and one end of the guide needle passes through the output end of the guide drill to form a puncture part for bone puncture, and the output end of the guide drill can be inserted into the guide drill. The puncture part is bent under the guidance of the puncture part; the puncture part passes through the cannula, and the guide drill and the guide needle can pass through the cannula along the axis direction. The present application has the advantages of improving drilling accuracy, saving operation time, and completing the fabrication of curved bone tunnels conveniently and quickly. |
