    • A biopsy device includes a first longitudinal element having a first longitudinal element FLE extending from a first element proximal end to a tissue piercing first element distal end and, FLE defining a first lumen extending there through from a proximal opening at the first element proximal end to a distal opening at the first element distal end. FLE is sufficiently flexible to be inserted to a target site along a tortuous path within a natural body lumen and a second longitudinal element SLE extending from a proximal end to a tissue piercing second element distal end. SLE is sized to be slidably received in the first lumen and defining a second lumen extending there within to a tissue receiving opening at the second element distal end. SLE is sufficiently flexible to be inserted to a target site along a tortuous path within a natural body lumen.
    • 活检装置包括第一纵向元件,第一纵向元件具有从第一元件近端延伸到组织穿刺的第一元件远端的第一纵向元件FLE,以及限定从第一元件近端处的近端开口延伸到其的第一内腔的FLE, 在第一元件远端处的远端开口。 FLE具有足够的柔性,以沿着自然体腔内的曲折路径插入目标部位,以及从近端延伸到组织刺穿的第二元件远端的第二纵向元件SLE。 SLE的尺寸被设计成可滑动地容纳在第一内腔中,并且将第二内腔限定在第二元件远端处的组织接收开口内延伸的第二腔。 SLE具有足够的柔性,可以沿着自然体腔内的曲折路径插入目标部位。

    • A biopsy device includes a longitudinal element sufficiently flexible to permit insertion into a body. The longitudinal element extends from a proximal end to a distal end and includes a lumen extending therethrough. The device also includes a stylet slidably received within the lumen having a distal end split into a pair of arms biased away from one another so that, when distal end of the stylet is advanced out of a distal end of the longitudinal element, the arms separate from one another into a tissue receiving configuration, the stylet including a tissue receiving space between the arms. The stylet is coupled to a handle via which the stylet is drawn proximally into the lumen of the longitudinal element so that contact between the longitudinal element and the arms draws the arms toward one another into a tissue capture configuration in which tissue is gripped therebetween.
    • 活检装置包括足够柔性以允许插入体内的纵向元件。 纵向元件从近端延伸到远端并且包括延伸穿过其中的内腔。 该装置还包括可滑动地容纳在内腔内的探针,该探针具有分离成彼此偏离的一对臂的远端,使得当探针的远端从纵向元件的远端推出时,臂分离 探针从另一方面进入组织接收结构,探针包括臂之间的组织接收空间。 探针被联接到手柄,通过该手柄将探针向近侧拉入纵向元件的内腔,使得纵向元件和臂之间的接触将臂朝向彼此拉伸成组织捕获构造,其中组织夹在其间。
