Attorney, Agent or FirmInternational ClassA61B 005/103AbstractA force transducer for a joint prosthesis is disclosed. The transducer includes A f5RUw,V,central body having a plurality of cavities formed therein from a lower surface. Each cavity defines a flexure member. A plate is located on the side opposite the cavities and connect to each flexure member through support posts. The support posts localize three applied to the plate to each flexure member. Force sensing elements attached to each flexure member provide a signal corresponding to the force applied to the flexure member.Field of SearchJoint distractorAcetabular cup positioner Prosthesis insertor or extractor Spinal positioner or stabilizer Orthopedic instrumentation Gauging or measuring device Along or about mutually orthogonal axes Three dimensional (e.g., x, y, z axes) Using a resistance strain gage Using a resistance strain gage Flexible element (e.g., beam, plate, or web) Parallel Resistance strain gage Flexible element (e.g., beam, plate, or web) Specific type of elastic member | |
