Abstract
A tool, system and method for separating connected orthopaedic components are disclosed. The system includes two orthopaedic components that are connected end to end. One of the orthopaedic components has a notch that receives a cam carried by the tool. The notch and cam are sized and shaped so that when the cam is turned, the cam forces the two components apart. The invention is particularly useful when Morse tapers are used to connect the components. The invention can be used with the modular orthopaedic implants as well as with modular trials used intraoperatively. The cam can be removably mounted on the tool.
Claims6
A disassembly device for use in separating two orthopaedic components, the disassembly device comprising:
- a pair of handles pivotally connected;
- at least one cam on each handle, the cams being opposite to each other;
- the two cams being movable toward and away from each other;
- wherein the handles and cams are made of a material suitable for surgical use;
- and
- wherein the handles are sized and shaped to be manually operable.
A method of separating two connected orthopaedic components, each of the orthopaedic components having at least one surface,
- wherein at least one of the orthopaedic components has a notch open to a surface of the adjacent orthopaedic component when the two orthopaedic components are connected;
- the method including:
- inserting a cam in the notch;
- moving the cam in the notch so that the cam acts against the connected orthopaedic components to separate the orthopaedic components.
The method of claim 22 wherein the step of moving the cam comprises rotating the cam to cause relative longitudinal movement between the orthopaedic components.
