    • A driver instrument with dual holding features for use with a combination of a medical staple and movable washer with that are used in a surgical procedure for attaching a ligament, or the like, onto a bone surface. The driver includes a straight body that is preferably cylindrical, is formed of a hard metal and includes a hand engaging central portion. A driver top end is flanged outwardly into flat head end that can be struck, as with a hammer to impart a hammer force therethrough, with the driver lower end portion formed with a threaded portion for turning into a threaded hole formed through a web of the medical staple, and with a spring collet formed with, or connected axially to, the driver lower end portion. Installation of the medical staple and washer onto the driver involves passing the spring collect through the staple web hole ahead of the driver threaded portion, and through a smooth walled hole formed through the movable washer, with a spring collet ring end passing through the washer hole and restricting removal therefrom. The driver that mounts the medical staple and movable washer, is held by a surgeon to position the staple legs onto a bone surface, straddling a ligament, and then is used to seat the staple into which bone by applying a hammer force to the driver head end. Whereafter, the driver threaded portion is turned out of the staple web threaded hole, pulling also the driver spring collet section out of the washer hole.
    • 具有双重保持功能的驱动器具,用于与医用订书钉和可移动垫圈的组合一起使用,用于将韧带等附接到骨表面的外科手术中。 驱动器包括优选为圆柱形的直体,由硬质金属形成并包括手接合中心部分。 驱动器顶端向外凸出成平头部,与锤子一样可以被击打以施加锤击力,驱动器下端部分形成有螺纹部分,该螺纹部分转变成通过网状物形成的螺纹孔 医用订书钉,以及与驱动器下端部分形成或轴向连接的弹簧夹头。 将医用订书钉和垫圈安装在驾驶员上,包括使弹簧收集器穿过驱动器螺纹部分前方的订书钉孔,并穿过可移动垫圈形成的平滑的壁孔,弹簧夹头环通过垫圈孔 并限制从中取出。 安装医用订书钉和可移动垫圈的驱动器由外科医生保持,以将钉腿定位在骨表面上,跨过韧带,然后用于通过向驱动头施加锤击力来将钉放置在其中 结束。 此后,驱动器螺纹部分从订书钉卷筒螺纹孔转出,也将驱动器弹簧夹头部分拉出垫圈孔。

    • A pin is provided for securing a replacement ligament inside a tunnel of a receptor bone. The pin includes a body portion having a threaded section for engaging the receptor bone to anchor the pin in the receptor bone. The body portion also includes a tapered shank located adjacent the threaded portion. The tapered shank is configured to enter a drilled hole having a predetermined diameter formed in the replacement ligament to force the replacement ligament against the wall of the tunnel. The tapered shank has a first diameter at a first end of the tapered shank opposite the threaded portion which is smaller than the predetermined diameter of the drilled hole and a second diameter adjacent the threaded portion which is larger than the predetermined diameter so that the tapered shank engages the replacement ligament in the tunnel as the pin is inserted through the drilled hole in the replacement ligament to force the replacement ligament against a side wall of the tunnel to promote healing of the replacement ligament within the receptor bone. The pin further includes a head coupled to an end of the body portion adjacent the threaded section for driving the pin into the receptor bone.
    • 提供一个销,用于将置换韧带固定在受体骨的隧道内。 销包括主体部分,该主体部分具有螺纹部分,用于接合受体骨以将销锚定在受体骨中。 主体部分还包括位于螺纹部分附近的锥形柄部。 锥形柄构造成进入具有形成在置换韧带中的预定直径的钻孔,以迫使置换韧带抵靠隧道的壁。 锥形柄在锥形柄部的与螺纹部分相对的第一端处具有小于钻孔的预定直径的第一直径,并且与螺纹部分相邻的第二直径大于预定直径,使得锥形柄部 当销钉穿过置换韧带中的钻孔插入隧道中时,将替换的韧带与隧道中的替换韧带接合,以迫使置换韧带抵靠隧道的侧壁,以促进受体骨内置换韧带愈合。 销还包括联接到主体部分的与螺纹部分相邻的端部的头部,用于将销引导到受体骨中。
