发明名称 Rod reduction device
摘要 A rod reduction device includes a housing defining a longitudinal axis. The housing has first and second arms extending distally therefrom. The distal ends of the arms are configured to releasably attach to a bone anchor. An anvil is operatively associated with the first and second arms of the housing and translatable along the longitudinal axis for facilitating the insertion of a spinal rod into the bone anchor. The anvil and each arm are positionable between an open position and a closed position.

主权项 1. A rod reduction device, comprising: a housing defining a longitudinal axis; a first arm and a second arm that extend distally from the housing, each of the first arm and the second arm including a proximal end and a distal end, the first arm pivotably secured to the housing at a first location and the second arm pivotably secured to the housing at a second location different from the first location, the proximal ends of the first arm and the second arm being pivotably secured to the housing such that the distal ends of the first arm and the second arm are releasably attachable to a bone anchor upon being pivoted relative to the housing about the proximal ends of the first arm and the second arm, respectively, each of the first and second arms including respective first and second outer surfaces; and an anvil supported on the first arm and the second arm and being distally translatable relative to the housing along the first arm and the second arm such that the anvil engages the first and second outer surfaces of the first and second arms to transition the first and second arms from a non-parallel orientation towards a parallel orientation and for facilitating insertion of a spinal rod into the bone anchor, the anvil defining an arch that opens distally.
