摘要：
The present invention provides a medical needle for repeating piercing operation on an object. The medical needle comprises a needle body and a metal glass material layer. The metal glass material layer is formed on the surface of needle body, and the metal glass material layer contains the alloy consisting of aluminum, zirconium, copper and niobium. In which, by enclosing the needle body by the metal glass material layer, the sharpness of the medical needle can be maintained to enhance durability after multiple piercing operations, so as to reduce the growing rate of maximum piercing force required for the medical needle as the number of piercing operations increases, and reduce the damage to the object caused by piercing operations.一種醫療用針具，用以對物體反覆執行穿插操作。醫療用針具包括針具本體及金屬玻璃材料層，金屬玻璃材料層形成於針具本體之表面，且金屬玻璃材料層包括鋁、鋯、銅及鉭所組成之合金。其中，藉由金屬玻璃材料層包覆針具本體，使得醫療用針具執行多次穿插操作後，仍能維持醫療用針具之銳利度以提升耐用性，降低醫療用針具隨著穿插操作次數增加所需之最大穿插力增幅，並減少穿插操作對物體造成之損害。
