    • Trocar seal assemblies are disclosed which consist of a protective member and a retaining member. The protective member prevents accidental perforations of the retaining member during the insertion of an instrument through the seal assembly and assists in forming a seal against the instrument when inserted in the seal assembly. The protective member is generally configured with a circular upper portion and a generally conical lower portion. The lower portion of the protective member consists of a plurality of flaps which increasingly overlap as they progress to the lower portion of the conical shape, thereby forming a seal at the lowest portion where the flaps overlap entirely. The overlapping flaps expand with minimal resistance when instruments are inserted through the seal assembly, thereby ensuring a proper seal regardless of the size or configuration of the instrument.
    • 公开了由保护构件和保持构件组成的套管针密封组件。 保护构件防止在通过密封组件插入仪器期间保持构件的意外穿孔,并且当插入到密封组件中时有助于形成对仪器的密封。 保护构件通常构造成具有圆形的上部和大致圆锥形的下部。 保护构件的下部由多个襟翼构成,当它们前进到圆锥形的下部时,它们越来越重叠,从而在襟翼完全重叠的最下部形成密封。 当仪器通过密封组件插入时,重叠的襟翼以最小的阻力膨胀,从而确保了适当的密封,而与仪器的尺寸或构型无关。

    • An obturator has an elongated shaft with a first shaft portion and a second shaft portion within an obturator housing. The distal end of the first shaft portion creates a first shield and the distal end of the second shaft portion creates a second shield. A blade having a piercing tip and cutting edges is interposed between the first shield and the second shield. In use, once the piercing tip passes the body wall, the first shield moves to cover the piercing tip and protect internal organs from accidental injury while the cutting edges continue to cut the body wall. Once the second shield passes through the body wall, the second shield moves to cover the cutting edges.
    • 闭塞器具有细长轴,其具有第一轴部分和位于封闭器壳体内的第二轴部分。 第一轴部分的远端形成第一屏蔽,并且第二轴部分的远端形成第二屏蔽。 具有穿刺尖端和切割刃的刀片插入在第一护罩和第二护罩之间。 在使用中,一旦刺穿尖端通过体壁,第一个护罩移动以覆盖穿刺尖端,并保护内部器官免受意外伤害,同时切割刃继续切割体壁。 一旦第二个屏蔽穿过主体壁,第二个屏蔽就移动以覆盖切割边缘。
