The drill removal tool includes: a wire clamp for locking the K-wire in place; a base for connecting the drill removal tool to the bone; a rack extending between the wire clamp and the base, and a drill bit remover. The drill bit remover includes an anvil configured to abut on a stop surface of the drill bit for applying a removal force to the drill bit and configured to be movable in a proximal direction along the rack relative to the wire clamp and the base to remove the drill bit from the bone. 本公开涉及一种钻移除工具,其用于从骨上移除钻头,同时将穿过所述钻头的K氏线保持在适当位置。所述钻移除工具包括:线夹,其用于将所述K氏线锁定在适当位置;基座,其用于将所述钻移除工具连接到所述骨;齿条,其在所述线夹和所述基座之间延伸,以及钻头移除器。所述钻头移除器包括砧座,所述砧座被构造成邻接在所述钻头的止挡表面上,用于向所述钻头施加移除力,并且被构造成可相对于所述线夹和所述基座沿所述齿条在近端方向上移动,以将所述钻头从骨上移除。
