发明名称 Microsurgical suture needle
摘要 The invention is directed to a microsurgical needle for use in microsurgical techniques. The distal segment of the needle is straight with a circular cross section, and has a sharpened tip with a triangular cross section having three sharp edges for cutting rather than tearing tissue during penetration. The middle segment of the needle has an acutely angled arched shape, and a transitional cross section which transitions between a squared cross section of the main shaft segment and the circular cross section of the straight distal segment. The main shaft segment of the needle has a generally squared cross section, and forms a broadly curved or arched shaft segment which may be easily gripped by a needle holder. The proximal end of the needle forms a suture attachment segment, and may be circular in cross section. The shape of the needle provides an easy angle, better stability, superior tissue alignment, and better control than conventional. needles, while the point is designed to minimize tissue trauma.
