Embodiment Construction
[0025] A sternum fixer with a pair of surrounding arms on a memory alloy wire single beam, including a single beam 1 made of a memory alloy wire, the two ends of the single beam 1 are relatively inwardly bent to form a surrounding arm 2, two The encircling arm 2 forms an open ring structure 5 on the longitudinal plane, and the middle section of the single beam is extruded and bent along the horizontal plane to form an arc-shaped pressure ring 3 on the horizontal plane. The plane where the pressure ring 3 in the middle section of the single beam is located is perpendicular to the plane where the open ring structure 5 is located. The ends of the surrounding arms 2 located at the opening in the open ring structure are bent inward. The end of the surrounding arm 2 located at the opening in the open ring structure has a rounded corner 4 .
