    • PROBLEM TO BE SOLVED: To provide a device for sheet insertion capable of simply inserting a sheet such as a synthetic absorbable anti-adhesion sheet, and the like, into a targeted in vivo site through a lumen of a trocar and using a trocar having a small diameter, in an endoscopic operation.SOLUTION: The device for sheet insertion includes: a cylindrical mantle tube 2 of which front and back ends are opened and inside is formed to be a sheet receiving part, and an extruding member 3 for extruding a sheet, the extruding member being inserted into the mantle tube in a state of moving in a back and forth direction that is a tube-axis direction and of rotatable, wherein the extruding member has a shaft 11 having a longer length than that of the mantle tube, a forked sheet winding part 12 disposed at a tip portion of the shaft, and a gripping part 14 for operation disposed at a back end of the shaft, the sheet winding part is received in the mantle tube by a movement of the extruding member backward while being protruded from a front opening of the mantle tube by a movement of the extruding member forward; and the mantle tube has axial slits 5 having a size enough to insert the sheet therethrough, which are formed on walls facing each other at the front end of the mantle tube over approximately the same length as a length of the sheet winding part.
    • 要解决的问题:提供一种用于片材插入的装置,其能够简单地将诸如合成可吸收防粘连片等的片材通过套管针的内腔插入目标体内部位,并使用 在内窥镜操作中具有小直径的套针针。 解决方案:用于片材插入的装置包括:前端和后端打开并且内部形成为片材接收部分的圆筒形外壳管2和用于挤出片材的挤出构件3,挤出构件是 在作为管轴方向的前后方向移动并且可旋转的状态下插入到套管中,其中,挤出构件具有长度大于套管的长度的轴11,叉形片卷绕 设置在轴的末端部分的部分12和设置在轴的后端处的操作的抓握部分14,片材卷绕部分通过挤出部件的向后移动而被接收在套管中,同时从 通过挤压构件向前的运动使套管的前开口; 套管具有轴向狭缝5,其具有足够的尺寸以将片材插入其中,这些狭缝5形成在与薄片卷绕部分的长度大致相同的长度上的与套管的前端相对的壁上。 版权所有(C)2013,JPO&INPIT
