Bone cement tube removal device for use in the reimplantation of an artificial femural stem

摘要

An instrument for removal of a hollow bone cement tube from a femur reimplantation having an elongate hollow tube adapted to be inserted into the bone cement tube to be removed with a collet at the insertion end of the hollow tube being radially expanded to engage the bone cement tube on the interior thereof by rotation of a mandrel having the collet threadedly engaged on the insertion end thereof. The hollow tube engages the collet to prevent relative rotation therewith and to allow the mandrel by threaded engagement with the collet to effect radial expansion thereof.
