    • An instrument for the surgical closure of a trocar puncture through a posterior fascia introduced during a laparoscopic operation comprises a tube (1) with a forward insertion end (2) and a rearward end (3), in whose shell wall (5) opposing window openings (7) are formed, in which terminates at its margins remote from the insertion end (2) of the tube (1) at least one bore (8) extending in the shell wall (5) in the longitudinal direction of the tube (1), hollow needles (10), each disposed in one of the bores (8) and displaceable between a retracted position, in which they clear the particular window opening (7), and an end position, in which they cross the window opening (7), and each having an inner channel (17), wherein each of the inner channels (17) of the hollow needles (10) forms a section of a guide channel for guiding through a suture thread (36), and this guide channel further includes at least one curved connecting section (18), which connects the front ends of the inner channels (17) of two hollow needles (10) when they are in their end positions and crossing opposing window openings (7), which, over its entire longitudinal length, is covered with respect to the outer space encompassing the tube (1) by an openable closure device (23) or is connected via a slot with the outer space encompassing the tube (1), wherein a segment of the suture thread (36) located in the connecting section (18) can be brought out of the connecting section (18) of the guide channel into the outer space through the slot or after opening the closure device (23).
    • 用于通过腹腔镜手术引入的后筋膜手术闭合套管针穿刺的仪器包括具有前插入端(2)和后端(3)的管(1),其中壳壁(5)与窗口相对 形成开口(7),其中远离管(1)的插入端(2)的边缘处终止在管壁的纵向方向上延伸到壳壁(5)中的至少一个孔(8) 每个孔都设置在孔(8)中的一个中,并且可以在它们清除特定的窗口(7)的缩回位置之间移位,并且其中它们穿过窗户开口 (7),并且每个具有内部通道(17),其中中空针(10)的每个内部通道(17)形成用于引导通过缝合线(36)的引导通道的一部分,并且该引导件 通道还包括至少一个弯曲连接部分(18) 在两个中空针(10)的内部通道(17)处于其端部位置并且穿过相对的窗口(7)的相对的窗口(7)的前端部分时,其在其整个纵向长度上相对于外部空间 通过可打开的闭合装置(23)包围管(1),或者通过狭槽与包围管(1)的外部空间连接,其中位于连接部分(18)中的缝合线(36)的段可以 从引导通道的连接部分(18)通过狭槽或在打开关闭装置(23)之后被引出到外部空间中。
