A spiral bone-fracture fixer has a spiral belt. The spiral belt is fixed on a bone-fracture section of a bone with a spiral-wound type, and then the spiral belt covers the bone fixedly. Thus, the spiral bone-fracture fixer can use the strength of the spiral belt to fix the bone. Accordingly, the bone-fracture fixed effect of the spiral bone-fracture fixer is excellent. The spiral bone-fracture fixer is convenient in operation to shorten the time of surgery. A surgical wound of patient is small and heals quickly.本發明係一種螺旋式骨折固定器,其包含一螺旋固定帶,該螺旋固定帶能以螺旋捲繞型態固定於骨頭之骨折區段,將骨頭完全包覆固定,藉此,不僅利用螺旋固定帶本身之強度將骨頭穩固地定位,達到良好的骨折固定效果,在手術操作上也簡便容易,而能縮短手術時間,且使病患手術後之傷口小,有助於手術後的復原。1‧‧‧螺旋固定帶3‧‧‧骨頭
