    摘要： An orthopedic device set includes a plurality of intervertebral spacer elements, an instrument for holding the spacer elements during the insertion and removal thereof into and out from between adjacent vertebral bones, and a tool which facilitates the loading and unloading of the spacer elements into and out of the instrument. The tool includes a handle and a bifurcated end having a pair of similarly curved tines. The bifurcated end is engageable with each spacer element during the loading and unloading of the spacer element.

    摘要： An instrument for insertion, implanting, and removing a cylindrical intervertebral spacer member having a deep circumferential groove, including: a shaft having a proximal end and a distal end, said proximal end forming a handle and the distal end forming a spacer member engaging subassembly; said spacer member engaging subassembly including at least one selectively expanding and contracting enclosure into which a central core of the spacer member may be introduced when the engaging subassembly is in the expanded state, and which holds the spacer member so that it cannot move when the selectively expanding and contracting enclosure is rendered into the contracted state; and an actuating mechanism, extending from the proximal end to the distal end, by which the spacer member engaging subassembly may be selectively expanded and contracted.

    摘要： An instrument for inserting and removing an intervertebral spacer into and out from an intervertebral space between adjacent vertebral bones, the spacer having a trunk portion having a longitudinal axis and flange portions at each longitudinal end of the trunk, the instrument including: a shaft having a proximal end and a distal end; the proximal end including a handle; and a holding structure provided at the distal end, which holding structure includes an enclosure within which the trunk of the spacer may be selectively introduced and maintained therein, the holding structure having an opening leading to the enclosure and through which opening the trunk of the spacer may be selectively passed to when forced therethough.
