摘要：
An interspinous process implant comprising an elongated body defining a longitudinal axis and an interior cavity. The implant includes engagement members movable between a first position stowed within the interior cavity and a second position deployed from the interior cavity. Each engagement member includes a central hub defining a hub axis perpendicular to the longitudinal axis of the body. Each central hub has an inwardly extending crank pin. The crank pins are radially offset from the hub axis and circumferentially spaced apart from one another. The implant also include an elongated drive shaft mounted for axial movement within the interior cavity and includes a distal actuation portion having upper and lower yokes positioned to cooperate with the crank pins. Upon axial movement of the drive shaft the crank pins translate through respective arcuate paths about the hub axis, causing corresponding rotational movement of the engagement members about the hub axis.
