| Abstract: | A system for strain measurement between the prosthesis and the spacer in the medical operation of total knee replacement(TKR) is proposed.It can help doctors to know the strain distribution in the knee and can make sure whether the strain is in balance.The force sensor is used to gauge the strain,the micro CPU is used for system control and data processing.Datas are transmitted by wireless way and the results are visually and real-time displayed.The errors are analyzed theoretically.The test scheme and test results are given as well and results are processed to improve the system precision.The result shows the system has the features of high efficiency,reliability,high precision,which verify the feasibility of the design. |
