Abstract：Professor Zhu Hanzhang invented a kind of sharp separating needle named needle-knife. His patent for invention "series of closed surgical needles" includes 12 types of needles. Needle-knife includes a needle, needle body and needle handle. Flat gourd-shaped or trapezoid handle of needle-knife is parallel to the blade line. The body of needle-knife is a cylinder. The different shape of the head of needle made various types of needle-knife. Professor Zhou Jianbin invented the blunt separation needle named yuandun needle. Yuandun needle includes a needle body and needle handle. The body of yuandun needle is long cone-shaped and the head is round-shaped. The handle of yuandun needle is bamboo-shaped. The treatment of acupotomy and yuandun needle therapy was based on body bowstring mechanical anatomy system and "mesh theory" of pathological framework of chronic soft tissue injury from Professor Zhang Tianmin. The cutting ways of acupotomy includes longitudinal dredging method, transverse dissection method, insert cutting method, stripping of bone surface method, permeability stripping method. Yuandun needle therapy includes parallel stab method and oblique stab method. The advantage of acupotomy is the ability to loosen soft tissue effectively and the defect is that it may damage normal human tissue. The advantage of yuandun needley is that it can safely loosen soft tissue and the defect is the limitation of treatment that cannot penetrate the dense connective tissue. Professor Zhou Jianbin invented tong needle, which can meanwhile sharp separate and blunt separate. Tong needle plays the advantages of needle-knife and yuandun needle and avoids the defects of needle-knife and yuandun needle.
