    • A biopsy system comprises an introducer, a biopsy device having a needle, and a marker applier. The introducer may include a closed distal tip, a lateral aperture, a proximally facing interior wall, and a ramp that guides the closed distal end of a marker applier up and into abutment with the wall as the applier is fed into the introducer. The needle of the biopsy device includes a blunt distal end and features providing clearance for the ramp as the blunt distal end is brought into abutment with the wall when the needle is fed into the introducer. The introducer may alternatively include an open distal end having resiliently biased leaves that bear against an inserted biopsy device needle. In some other versions, a fin projects laterally from the closed distal end of a marker applier, spacing the distal end away from a sidewall region of the introducer cannula.
    • 活检系统包括导引器,具有针的活检装置和标记器。 引导器可以包括封闭的远侧末端,侧向孔,朝向内侧的内壁,以及斜坡,当施加器被馈送到导引器中时,该斜面将标记物施加器的封闭远端引导向上并与壁邻接。 活检装置的针包括钝的远端,并且当针被送入导引器时,当钝头远端与壁抵接时,该特征为斜面提供间隙。 导引器可以可选地包括具有弹性偏置的叶片的敞开的远端,该叶片抵靠插入的活检装置针头。 在一些其他形式中,翅片从标记物施加器的封闭远端横向突出,使远端远离引导器套管的侧壁区域。

    • A biopsy device comprises a body, a needle, and a cutter actuation mechanism. The needle extends distally from the body. The cutter actuation mechanism rotates and translates the cutter relative to the body and relative to the needle. The cutter has an overmold presenting a lead screw and a hex portion. The cutter actuation mechanism comprises a first gear disposed about the hex portion of the overmold and a second gear engaged with the lead screw of the overmold by a nut that is integral with the second gear. The cutter actuation mechanism is operable to simultaneously rotate the first gear relative to the body at a first rotational speed and the second gear relative to the body at a second rotational speed. With the lead screw and the nut rotating at different rotational speeds, the lead screw rotates relative to the nut at a third rotational speed.
    • 活检装置包括主体,针和切割器致动机构。 针从身体向远处延伸。 切割器致动机构使刀具相对于主体相对于针旋转并平移。 刀具具有一个包含一个导螺杆和一个十六进制部分的二次模型。 切割器致动机构包括围绕包覆模制件的六边形部分设置的第一齿轮和通过与第二齿轮成一体的螺母与包覆模制体的导螺杆啮合的第二齿轮。 切割器致动机构可操作以在第一旋转速度下相对于主体同时旋转第一齿轮,并且第二齿轮以第二旋转速度相对于主体旋转。 利用导螺杆和螺母以不同的转速旋转,导螺杆以第三转速相对于螺母旋转。
