Abstract: An auxiliary bone reinforcement structure includes a deformable hollow body having multiple bosses formed on an outer periphery of the hollow body and a connection portion, a connector detachably connected to the connection portion and having an annular groove defined in an outer periphery of the connector and an injector detachably connected to the connector for injection of a medicine into the hollow body whereby the hollow body is deformed after the medicine is injected into the hollow body and thus able to stuff a hole in the bone.

Abstract: A clamping device includes a body having a centrally defined passage and two holes formed on opposite sides of the body to communicate with the passage, a handle rotatably received in the passage and having an abutting member extending into an outer periphery of the handle, a clamping member having two distal ends extending into the passage and out of the two holes respectively to be abutted by the abutting member, and a ratchet member provided to prevent undesired rotation between the body and the handle.
