    摘要： A spinal fixation element rotation instrument with two lever arms is provided. The lever arms are connected to each other at distal ends thereof. The second lever arm rotates relative to the first lever arm. The distal ends of the first and second lever arms are adapted to couple to a spinal fixation element. The distal ends of the lever arms may have a dual ratchet feature that prevents rotation in a set direction. When one arm rotates back and forth, the other arm is held stationary. As a result, the spinal fixation element rotates in a predetermined direction and is prevented from rotating back toward its initial position. The direction of the rotation of the spinal fixation element may be set using knobs or switches provided at a proximal end of one or both of the lever arms.

    摘要： Disclosed herein are devices and methods for removing tissue. In one aspect, a device for removing tissue includes a hollow elongate member having an outer wall and a lumen, a selectively deployable tissue-cutting element extending from the hollow elongate member, and an actuation member extending through the lumen and coupled to the hollow elongate member at a location that is distal to the tissue-cutting element. Movement of the actuation member can cause the tissue-cutting element to move from the insertion configuration where the tissue-cutting element is not deployed to a tissue- cutting configuration where the tissue-cutting element is deployed such that it is radially extended relative to the insertion configuration.
