摘要： A rotation shaft (100) includes a body (10), a threaded rod (30), an anvil (50), a linkage (70) and a biasing member (90). The body includes a threaded portion (18) disposed along an inner surface of a longitudinal throughhole (16). The threaded rod includes a distal end, the threaded rod configured to engage the threaded portion. The anvil is coupled to the distal end of the threaded rod. The linkage is coupled to the anvil. The biasing member is partially disposed about the linkage distal of the anvil, wherein rotation of the threaded rod translates into linear movement of the linkage relative to the body.

摘要： A rod reducer including a housing defining an opening, a body member defining an opening and a slot, a shaft disposed through the opening of the housing and coupled to the opening of the body member, an anvil including a linkage extending therefrom, the linkage coupled to the body member and the anvil, a plurality of arm members, and a biasing element disposed between the body member and the anvil. A pin of the linkage is slidably disposed within the slot, and the biasing element is configured to bias the anvil distally with respect to the body member. Rotation of the shaft translates into linear movement, relative to the housing, of the shaft, the body member, and the anvil. The arm members are coupled to the housing and movable towards a parallel configuration as the anvil is advanced away from the housing to engage a bone screw.
