Abstract

Disclosed is an implant needle for introducing an implant into a patient. The needle has a hollow main body having a receiving portion configured to receive an implant. A taper-shaped tip portion is cut from the hollow needle main body and includes a first slant surface contiguous to an outer peripheral surface of the main body and formed at a first predetermined angle with respect to an axis of the main body. The first slant surface has an inner non-cutting edge and an outer non-cutting edge. The needle also includes a pair of second slant surfaces, each of which forms a second predetermined angle with respect to the main body axis that is larger than the first predetermined angle. Each second slant surface has an inner non-cutting edge and an outer cutting edge that is contiguous with an edge point of the tip portion. A method of manufacturing the implant needle is also disclosed.
