Abstract
An arthroscopic needle having partial cuts or serrations along one side of a circular, hollow needle shaft allows the needle to bend, or articulate, by drawing a pull strip bar, defined by a thin strip along the interior side closet to the serrations in the hollow shaft, for compressing along the cuts to draw uncut segments into closer arrangement for curving the needle in the direction of the compressed side. The selectively articulating, or “bendable” needle that curves in response to a rotating knob provides for insertion of surgical attachment anchors in difficult-to-reach areas of meniscal tissue. The disclosed articulating needle has the ability to bend and access more anterior and posterior zones of meniscal repairs than conventional rigid needle approaches.
