Controlled Apparatus And Method For Extracting Cement Mantles From Bone Recesses
US Patent:
5190551, Mar 2, 1993
Filed:
Dec 14, 1990
Appl. No.:
7/628390
Inventors:
ALbert K. Chin - Palo Alto CA

Assignee:
Zimmer, Inc. - Warsaw IN
International Classification:
A61B 1756
US Classification:
606 99
Abstract:
A cement plug received within a bone recess is extracted by forming a bore within the plug, tapping the bore to form internal screw threads therein, engaging the threads with a pulling tool, and applying tension to the tool to extract the plug. The bore is formed through means of a rod inserted into the plug while in a fluid state and/or a drill bit having a tubular guide received therearound to maintain the bit in generally aligned condition with the bone recess and limit the depth to which the bit penetrates the plug. The degree to which the bore is tapped and engaged by the pulling tool is controlled to avoid exceeding the extent of the bore and the screw threads formed therein. One embodiment employs a self-tapping extraction rod which serves both as a tap to form the screw threads and as the pulling tool to apply tension to extract the plug. Another embodiment employs a tap which is separate from the pulling tool.
Multi-Part Method And Apparatus For Removing Pre-Placed Prosthetic Joints And Preparing For Their Replacement
US Patent:
5078718, Jan 7, 1992
Filed:
Apr 17, 1990

Assignee:
Origin Medsystems, Inc. - San Mateo CA
International Classification:
A61F 504
US Classification:
606 86
Abstract:
A method and apparatus for removing a pre-placed prosthetic joint from a bone cavity and conditioning the cavity for receipt of a replacement joint. The pre-placed joint is first pulled from the mantle of hardened cement holding it within the cavity, thus leaving a cavity within the mantle. A mass of fluid cement is then placed within the cement cavity, after which a pulling tool is inserted into the fluid cement and the fluid cement is permitted to cure to bond with the hardened cement and form an integral mass. The pulling tool has detachable sections or sleeves, each with grip forming elements on its exterior and structure to connect a slap-hammer to its proximal end. Tension is then applied to the each section to remove the section and the cement mantle surrounding it from the bone cavity. The process is repeated for each section until all of the cement mantle is removed.
Multipart Kit And Method Of Using The Same To Remove Cement Used To Secure Prosthetic Joints
US Patent:
5041120, Aug 20, 1991
Filed:
Jan 19, 1990
Appl. No.:
7/467724

Assignee:
Origin Medsystems, Inc. - San Mateo CA
International Classification:
A61B 1756, A61B 1750
US Classification:
606 99
Abstract:
A mantle of cement having an elongate cavity formed therein is removed from adhered condition within a bone recess by successively breaking away sections of the mantle with a plurality of elongate screw threaded pulling elements proportioned to engage a limited length of a screw threaded mass of cement received in the cavity. The apparatus of the invention is provided in kit form with sufficient elements to enable the full length of the mantle to be removed in successive steps. The kit may also include a cement injection syringe and vent tube to fill the cavity of the mantle with a mass of cement, a die to form a screw threaded passage in the mass of cement, and a slap hammer connectable to the pulling elements.
Method And Apparatus For Extracting A Cement Mantle From A Bone Recess
US Patent:

International Classification:
A61F 500, A61F 232
US Classification:
606 86
Abstract:
A method and apparatus for removing a pre-placed prosthetic appliance anchored in place in a bone recess by a cement mantle and conditioning the recess for receipt of a replacement appliance. The preplaced appliance is first pulled from the mantle of hardened cement holding it within the recess, thus leaving a cavity within the mantle. A screw threaded post having nuts threadably engaged therewith at longitudinally spaced locations is then anchored within the cavity with a new mass of cement. Thereafter, the post is threadably disengaged from the nuts, leaving the nuts in place within the new mass of cement. A pulling tool is then successively engaged with the nuts and tensioned to incrementally remove the mantle from the recess.
