Abstract
Abstract A plier-like tool used to grab anchors have a pair of projections which fits into the anchor cavities. A pair of arms are pivotally connected together which provide for rotation of the projections in the same plane near the distal end of each arm. The projections in cross-section are square and uniform over the length of the projections. The projections move together when the arms are squeezed together by the operator.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
169 words
A surgical tool for use in gripping and manipulating the recessed anchor of a suture and anchor assembly, comprising; a pair of pivoted arms which rotate in the same plane; both arms on one side of said pivot means having a gripping shape for use when the tool is held in a human hand; each arm on the opposite side of said pivot means having a similar four sided projection, with all adjacent sides of the opposing projections being in the same planes when the flat front face of each projection is near touching, by the squeezing action of said human hand; said projections being of equal length, which would be equal to approximately half the diameter of the said suture anchors minus the width of the off-center barrier between the opposing four sided recesses in the suture anchors; and said front face and adjacent sides of the said projections having sharp edges capable of shearing the off-center barrier between the opposing four sides recesses in said suture anchors.
