摘要:
A surgical instrument and method for inserting a spinal implant (100, 170) in the intervertebral disc space between two adjacent vertebrae and an anchor (130, 140, 150, 160, 164, 166) engageable with the implant (100, 170) and an adjacent vertebra are provided. The instrument includes an inserter (200, 500) having an engagement portion including a distal engagement surface (206, 506) for interfacing with the implant (100, 170) and a handle portion (208, 508). The engagement portion includes a track (218, 220, 518, 519, 520, 521) for slidably translating the anchor (130, 140, 150, 160, 164, 166) toward the engagement surface (206, 506). A kit is provided including the inserter (200, 500) and a tamp (400, 600) to force the anchor (130, 140, 150, 160, 164, 166) into engagement with the implant (100, 170) and the adjacent vertebra. The kit may also include a cutter (300) for piercing the adjacent vertebra.
摘要:
The present application proposes a bone anchor (116), comprising an interconnection portion (172) to slidingly engage a spacer (112), a fixation portion (184) spaced apart from the interconnection portion to fix the anchor to a bone, and a leg (196, 198) connecting the fixation portion (184) to the interconnection portion.

The engagement portion includes a pair of tracks (518, 519; 520, 521) provided on at least one of superior and inferior surfaces for slidably translating the anchor toward the engagement surface, wherin the pair of tracks cross on the surface. A kit is provided including the inserter (200, 500) and a tamp (400, 600) to force the anchor (130, 140, 150, 160, 164, 166) into engagement with the implant (100, 170) and the adjacent vertebra.

摘要:
A hand held instrument (100) in a kit (200) for use in positioning a constraining ring (16) of an acetabular liner (14) system and includes a shaft (202) including a first coupling member (108), and a plurality of heads (204,206,...), each of the plurality of heads (204,206,...) including (i) a base (214,216,...) configured to couple with the first coupling member (108) and (ii) a pair of resilient gripper arms (224,226), each of the pair of resilient gripper arms (224,226) defining a constraining ring reception area having a size different from the constraining ring reception area defined by the pair of gripper arms (224,226) of each of the other of the plurality of heads (204,206,...) .
