    • A graft ligament strand tensioner includes a frame member for slidingly retaining loops of sutures extending from graft ligament strands. The tensioner further includes a collar portion, and is provided with a handle having a core portion on which the collar portion is disposed for axial movement, and a grip portion. The tensioner still further includes a spherical member connected to the handle and having rounded surfaces facing the collar portion. The collar portion is tiltingly movable on the spherical member rounded surfaces when manipulation of the handle, to pull sutures on the frame member taut, causes the collar portion to engage the spherical member rounded surfaces. The sliding retention of the sutures and the tilting movement of the collar portion provide substantial equalization of tension in the sutures and thereby the graft ligament strands.
    • 移植韧带股张紧器包括用于滑动地保持从移植韧带股延伸的缝合线的框架构件。 张紧器还包括一个套环部分,并且设置有把手,该把手具有一个芯部分,该套环部分设置在该芯部分上以便轴向运动,一个把手部分。 张紧器还包括连接到手柄并具有面向套环部分的圆形表面的球形构件。 当操纵手柄时,套环部分可在球形构件圆形表面上倾斜移动,以拉紧框架构件上的缝合线,使套环部分接合球形构件圆形表面。 缝合线的滑动保持和套环部分的倾斜运动提供缝合线和由此的移植物韧带股线的张力的显着平衡。
