Bone needle

The medical self drilling and self tapping fixed bone needle comprises an end bit blade part in an integrated structure, a cylinder part in the middle and an interface part at the tail end. The bit blade part includes a bit blade, a tapping blade and a fixed thread. The tapping blade is located between the bit blade and the fixed thread. The shape of the tapping blade is a gradual transition from a low and flat bit blade to a blade with the same fixed thread. The utility model overcomes the disadvantages of the existing bone needle, such as complex operation process, inconvenient operation, increased operation time and patient bleeding. The utility model can complete drilling, tapping and fixing the bone needle in one operation.
