The suture anchor (2) of Feng He Line (4) will be kept to be fixed in sclerous tissues using any well known method, especially in bone tissue, right Hou is using including that there is the fastener (3) of thermoplastic properties material to fasten, and the material is by the sclerous tissues in situ liquefied and can permeate wherein fixed suture anchor. The fastener is, for example, thermoplasticity plug (31) or thermoplasticity sleeve, is anchored in suture anchor (2) in the open area of identical sclerous tissues opening (5). Alternatively, fastener is thermoplasticity pin, is introduced into the inner cavity of suture anchor, wherein the material with thermoplastic properties is liquefied in the chamber and is extruded through in a liquefied state the channel of the outer surface of connection cavity and anchor.使用任何公知的方法將保持縫合綫（4）的縫合錨（2）固定在硬組織中，特別是骨組織中，然後使用包括具有熱塑性性質材料的緊固件（3）來緊固，所述材料被原位液化並能夠滲透其中固定縫合錨的硬組織。所述緊固件例如是熱塑性插塞（31）或熱塑性套筒，其在相同硬組織開口（5）的開口區域中錨固在縫合錨（2）上。可替代地，緊固件是熱塑性銷釘，其被引入縫合錨的內腔中，其中具有熱塑性性質的材料在該腔中被液化並且在液化狀態下被擠壓穿過連接空腔和錨的外表面的通道。
