阅读说明：本技术 铜铬合金在活检穿刺针中的应用 (Application of copper-chromium alloy in biopsy puncture needle ) 是由 陈小红 赵剑 刘平 周洪雷 梁晓飞 付少利 苗震 于 2021-07-13 设计创作，主要内容包括：本发明公开了铜铬合金在医用活检穿刺针中的应用,所述铜铬合金用作穿刺针的针芯和/或针管材料,所述铜铬合金的质量组分为10≤Cr≤20、0.04≤Zr≤0.1、余量Cu。本发明通过将抗磁材料Cu和具有顺磁性的Cr、Zr结合得到设计成分的铜合金,然后对比目前的医用不锈钢及钛合金不仅在磁化率的数值上大大的降低,具体表现在伪影面积和体积上也有明显的减少。同时也弥补了铜合金应用在医用活检穿刺术上的空白。(The invention discloses an application of copper-chromium alloy in a medical biopsy puncture needle, wherein the copper-chromium alloy is used as a needle core and/or needle tube material of the puncture needle, the mass components of the copper-chromium alloy are that Cr is more than or equal to 10 and less than or equal to 20, Zr is more than or equal to 0.04 and less than or equal to 0.1, and the balance is Cu. The invention combines diamagnetic material Cu with Cr and Zr with paramagnetism to obtain copper alloy with designed components, and then compared with the prior medical stainless steel and titanium alloy, the invention not only greatly reduces the numerical value of magnetic susceptibility, but also obviously reduces the artifact area and volume. Meanwhile, the blank of the copper alloy applied to the medical biopsy puncture is made up.)
