    • PROBLEM TO BE SOLVED: To provide an obturator having a sharp distal tip.
      SOLUTION: The obturator has an elongate tube 18; a handle 38 disposed at the proximal end; a cutting tip 43 disposed at the distal end of the elongate tube; a cutting part included in the cutting tip; a mounting part located on the proximal end side rather than the cutting part; and two mounting members included in the mounting part of the tip and respectively extended outward with respect to the axis of the tube so as to be frictionally engaged with the inner surface of the tube. At least one of the mounting members extends outward to an outer edge part with respect to the axis of the tube. The obturator further has a means provided at the outer edge part of the at least one mounting member to enhance a friction state between the at least one mounting member and the inner surface of the elongate tube. The means for enhancing the friction state is composed of a large number of serrated parts each of which is engaged with the wall of the tube, thus constituting the obturator to be used for penetrating a patient's body wall.

    • 要解决的问题:提供具有尖锐远端的堵塞器。

      解决方案:闭孔器具有细长管18; 设置在近端的手柄38; 设置在细长管的远端的切割尖端43; 包括在切割尖端中的切割部分; 位于近端侧而不是切割部的安装部; 以及两个安装构件,其包括在尖端的安装部分中并分别相对于管的轴线向外延伸,以与管的内表面摩擦接合。 至少一个安装构件相对于管的轴线向外延伸到外边缘部分。 闭塞器还具有设置在至少一个安装构件的外缘部分的装置,以增强至少一个安装构件与细长管的内表面之间的摩擦状态。 用于增强摩擦状态的装置由大量的锯齿形部分组成,每个锯齿部分与管的壁接合,从而构成用于穿透患者体壁的闭孔器。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a trocar assembly in which two or more instruments are coextensively inserted in the same trocar. SOLUTION: The trocar assembly by this invention has a cannula, the cannula has a stem extending between the proximal end and leading edge and a rigid housing portion having the leading edge and proximal end section, the leading edge of the rigid housing portion has a fixed relation with the cannula and an elastic housing portion incorporated in the proximal end section of the rigid housing portion, the elastic housing portion can be compressed in an axial direction, the rigid housing portion and elastic housing portion form a valve housing portion, compose a work channel together with the cannula, and have a shaft having a blockade instrument, in which a dimension and a profile are decided so as to removably insert through the work channel, and an axis line which is included in the blockade instrument and extends from the proximal end section to the sharp leading edge chip.
