Disclosed are a structure of medical leading wire and a manufacture method thereof. A core wire has a front section that is shaped in the form of a slender bar having a tapered diameter. The slender bar has a circumferential surface on which a plurality of raised fins arranged in a spaced manner with suitable intervals is integrally formed. A tip section is shaped to provide the tip section. A spiral coil having an inner diameter approximately identical to that of the raised fins and the tip section of the core wire, after the front section of the core wire is sleeved, the raised fins of the core wire is made to abut against an inner circumferential surface with at least one of the coils sleevedly encircling the tip section. The coil sleevedly encircling the tip section and the tip section are fused to integrally bond together, so that the spiral coil is concentrically sleeved and fixed to an outer circumference of the core wire through the raised fins and the tip section. As such, it is not only easy to manufacture the front section of the core wire, but also easy to assemble and couple the spiral coil to provide the front end of the leading wire with improved flexibility and restorability, thereby greatly improving the overall operability of the leading wire.一種醫療用導引線結構及其製作方法,其係將心線之前段部成型出漸進式縮小直徑之細長桿狀,並於該細長桿狀之環面上一體成型出複數個呈適當間隔距離排列之凸出鰭部,以及於頭端成型出頭端部,一內徑略相同於心線凸出鰭部及頭端部之螺旋線圈,於心線之前段部套穿後,可使心線之凸出鰭部頂抵於內環面,並使其中至少一線圈圈套於心線之頭端部,再將圈套於頭端部上之線圈與頭端部以熔接成型的方式結合一體,使得螺旋線圈可利用凸出鰭部及頭端部以同軸心固定套穿於心線的外部;藉此,不僅可易於製作出心線之前段部,且可易於組裝結合螺旋線圈,使導引線之前端具有較佳的可撓性及回復性,進而大幅提高導引線整體的操控性。10...導引線11...心線111...前段部112...凸出鰭部1121...導弧角113...頭端部114...手動部12...螺旋線圈
