    • An improved suture anchor driver includes a handle and an extending elongated shaft adapted for passing through arthroscopic portals. The distal end of the shaft engages the suture anchor. The shaft is cannulated to allow passage of a suture from the anchor to the handle. The shaft also has a slot in its wall and extending along most of its length in communication with the interior of the shaft. The handle has a grooved knob and adjacent resilient cap for retaining a needle. A sliding member is positioned on the shaft adjacent the needle. The intermediate portion of the suture is looped through an elastic hole in order to maintain it in tension. In use, the anchor is driven into tissue. As the driver is withdrawn, the suture pulls out of the elastic hole and through the shaft. The suture then pulls the needle from the groove. A portion of the needle slides in the slot as the needle travels along the cannula. The sliding member is pulled along by the needle. The sliding member protects the needle and helps to control the rate of its withdrawal.
    • 改进的缝合锚固器驱动器包括手柄和适于穿过关节镜入口的延伸细长轴。 轴的远端接合缝合线锚。 轴被插入以允许缝合线从锚定件通过手柄。 轴在其壁上还具有狭槽,并且沿其大部分长度延伸,与轴的内部连通。 手柄具有带槽的旋钮和相邻的弹性帽,用于保持针头。 滑动构件位于与针相邻的轴上。 缝合线的中间部分环绕弹性孔,以保持其处于张力。 在使用中,锚被驱动进入组织。 当司机撤出时,缝合线从弹性孔中拉出并穿过轴。 缝合线然后从凹槽中拉出针。 当针沿插管行进时,针的一部分在槽中滑动。 滑动构件被针拉动。 滑动构件保护针头并有助于控制其抽出速率。
