    • A tissue fixation device is provided that is preferably used to secure a ligament or graft within a prepared bone tunnel, for example in ACL replacement. The tissue fixation device generally includes an elongate member having a shaft portion that is adapted to be at least partially disposed within a bone tunnel, and a guide member that forms a portion of the proximal end of the elongate member. The guide member has a graft-seating surface that is effective to seat a graft and to position the graft toward one side of a bone tunnel when the device is disposed within the bone tunnel. The device also includes a graft-retaining member formed on at least a portion of the graft-seating surface.
    • 提供了一种组织固定装置,其优选地用于将准备的骨隧道内的韧带或移植物固定,例如在ACL替换中。 组织固定装置通常包括具有适于至少部分地设置在骨隧道内的轴部分的细长构件和形成细长构件的近端的一部分的引导构件。 引导构件具有移植座位表面,当移植物设置在骨隧道内时,移植物表面有效地固定移植物并将移植物定位在骨隧道的一侧。 该装置还包括形成在移植物座位表面的至少一部分上的移植物保持构件。
