    • A medical device (10) for treating stress urinary incontinence is provided. The device includes a cannula (20) with a plurality of apertures (34a, 34b, 34c). A plurality of needles (41, 42, 43) is disposed within a lumen (26) of the cannula. A handle (50) includes a housing (52) and a shifter mechanism (60) to translate the plurality of needles from a first position in which the needles are disposed within the lumen of the cannula, to a second position in which a distal portion of each needle extends out of the lumen through respective apertures. The handle also includes a slot (55) including a transversal track (55d) defining a potential range of rotational motion of the shifter mechanism with respect to the housing, and a plurality of longitudinal tracks (55a, 55b, 55c) defining a potential range of translational motion of the shifter mechanism with respect to the housing.
    • 提供了一种用于治疗压力性尿失禁的医疗装置(10)。 该装置包括具有多个孔(34a,34b,34c)的套管(20)。 多个针(41,42,43)设置在套管的内腔(26)内。 手柄(50)包括壳体(52)和移位机构(60),用于将多个针从布置在套管内腔中的第一位置平移到第二位置,在第二位置,远端部分 每个针通过相应的孔延伸出管腔。 手柄还包括一个狭槽(55),它包括横向轨道(55d),该横向轨迹限定换挡机构相对于壳体的旋转运动的潜在范围,以及多个纵向轨迹(55a,55b,55c) 移位机构相对于壳体的平移运动。
