    • An automated fine needle biopsy device is described for extracting tissue from the body predominantly in suspected cases of breast cancer. However, it can be used in other parts of the body accessible to needle biopsy. The device causes a fine needle, which is attached to the device, to reciprocate and/or rotate at the same time causing tissue to enter the needle. The depth and number of the thrusts can be pre-programmed, and the force behind each thrust is constant. Suction may or may not be used. The tissue extracted is subsequently expelled onto glass slides for microscopic interpretation. This device and method offer a vast improvement over the present method for fine needle biopsy wherein it is performed manually and in a very haphazard way. The prime deficiency of the manual method currently used is insufficient tissue extraction. This device will correct that situation enabling accurate diagnosis to be made on adequate tissue samples obtained. No similar device is known to be in clinical use at the present time.
    • 描述了一种自动细针穿刺活检装置,主要用于从怀疑的乳腺癌病例中提取组织。 然而,它可以用于身体的其他部分,可用于针刺活检。 该装置使得附接到装置的细针能够同时往复运动和/或旋转,从而使组织进入针。 推力的深度和数量可以预编程,每个推力背后的力是恒定的。 抽吸可以使用也可以不使用。 随后将所提取的组织排出到载玻片上进行显微解释。 该装置和方法相对于目前的细针穿刺活检方法提供了巨大的改进,其中手动执行并以非常随意的方式进行。 目前使用的手工方法的主要缺点是组织提取不足。 该装置将纠正这种情况,使得能够在获得的适当组织样本上进行准确的诊断。 目前没有类似的装置在临床上被使用。
