    • A needle biopsy device is disclosed. The biopsy device includes a housing, a needle set and an actuator assembly. The needle set includes a needle having a tissue receiving opening and a cutting element adapted to pass over or through the tissue receiving opening to sever tissue extending therein. The actuator assembly includes a first magnetic member fixed in a stationary position in the housing and a second magnetic member arranged in the housing so that the second magnetic member is either magnetically attracted toward or repelled from the first magnetic member. The second member is coupled to a respective one of the needle and cutting member so that movement of the second magnetic member effectuates movement of one of the needle and cutting element.
    • 公开了针活检装置。 活检装置包括壳体,针组和致动器组件。 针组件包括具有组织接收开口和适于穿过或穿过组织接收开口以切断延伸在其中的组织的切割元件的针。 致动器组件包括固定在壳体中的静止位置的第一磁性构件和布置在壳体中的第二磁性构件,使得第二磁性构件被磁性地吸引或者从第一磁性构件排斥。 第二构件联接到针和切割构件中的相应一个,使得第二磁性构件的运动实现针和切割元件之一的移动。
