We describe a novel but easy modification to percutaneous coaxial needle biopsy technique using readily available standard equipment to enable a predefined variable sampling length to be achieved. This technique involves the insertion of a carefully measured spacer between the coaxial cutting needle and guide needle. This can minimise the sampling length required to biopsy any given lesion, minimising the volume of traumatised tissue and preventing unnecessary penetration of tissues deep to smaller lesions, thus increasing procedure safety.
我们描述了一种新颖且简便的经皮同轴针活检技术改良方法，该方法使用现成的标准设备，能够实现预定义的可变采样长度。此技术包括在同轴切割针和引导针之间插入一个精确测量的间隔物。这可以将活检任何给定病变所需的采样长度减至最小，使受创组织的体积最小化，并防止对较小病变深部组织的不必要穿刺，从而提高手术安全性。
