    摘要： A trocar fixation device can comprise a cannula, at least one flap coupled to an exterior surface of the cannula within a central region of the cannula, and an elongate tube rotatably mounted onto the cannula and over the at least one flap. The elongate tube has at least one opening extending between an interior surface and an exterior surface of the elongate tube. In a free, activated state, the flap biases radially outwardly from the cannula. In a constrained, deactivated state, the at least one flap is positioned between the cannula and the elongate tube and maintained substantially parallel to the exterior surface of the cannula. The at least one opening in the elongate tube is sized and positioned such that rotation of the elongate tube in a first direction about the cannula exposes the flap in its entirety through the opening and allows the flap to activate.

    摘要： A balloon trocar includes a cannula assembly including a cannula and an outer sleeve fitting over the cannula. The distal end of the outer sleeve is proximal to the distal end of the cannula. A balloon is coupled to a distal portion of the sleeve and a distal portion of the cannula. The outer surface of the cannula includes a plurality of longitudinal channels for transmitting gas or fluid to the balloon. A bolster having a gel pad at its distal portion is slidably mounted to the cannula assembly and may be locked in a desired position. In use, the trocar is inserted into an incision through a body wall and into a body cavity. The balloon is inflated and the cannula assembly pulled proximally against the incision while the bolster is slid distally to the body wall and locked in place to seal the incision with the compressed balloon.

    摘要翻译： 气球套管针包括插管组件，其包括套管和套管上的外套管。 外套筒的远端靠近套管的远端。 气囊联接到套管的远端部分和套管的远端部分。 套管的外表面包括用于将气体或流体传送到球囊的多个纵向通道。 在其远端部分具有凝胶垫的枕头可滑动地安装到套管组件上并且可以锁定在期望的位置。 在使用中，套针针通过体壁插入切口并进入体腔。 气囊膨胀，并且套管组件向近侧拉动抵靠切口，同时将垫片向远侧滑动到体壁并锁定在适当位置以用压缩气囊密封切口。

    摘要： A trocar fixation device includes a cannula and an elongate tube mounted onto and coupled to the exterior surface of the cannula with the distal end of the cannula extending distally beyond the distal end of the elongate tube. The elongate tube includes a plurality of slits cut at an angle to a longitudinal axis of the elongate tube. The trocar fixation device is activated by rotating the proximal-end region of the elongate tube in a first direction and is deactivated by rotating the proximal-end region of the elongate tube in a second direction, opposite to the first direction. Activation of the trocar fixation device compresses the material positioned between adjacent slits and forces the material radially outwardly, away from the exterior surface of the cannula, thereby forming ridges. Deactivation of the trocar fixation device returns the exterior surface of the elongate tube to a substantially smooth condition.

    摘要翻译： 套管针固定装置包括插管和安装到套管的外表面上并连接到套管的外表面的细长管，套管的远端向远侧延伸超过细长管的远端。 细长管包括与细长管的纵向轴线成一定角度切割的多个切口。 套管针固定装置通过沿着第一方向旋转细长管的近端区域而被激活，并且通过沿与第一方向相反的第二方向旋转细长管的近端区域来停用。 套针针固定装置的激活压缩位于相邻狭缝之间的材料，并迫使材料径向向外，远离插管的外表面，从而形成脊。 套针针固定装置的停用将细长管的外表面返回到基本平滑的状态。
