Abstract：To design a laparoscopic training evaluation system, and verify the feasibility of the system through the test.The operation time, the average speed, the stability of movement and the free rate were choosen as the measurement index of this evaluation system.The micro electronic mechanical system(MEMS) acceleration sensor was used and the module of MEMS acceleration sensor was designed;the Kalman filtering algorithm was taken for data filtering of accelerometer and gyroscope in time domain, and the influence of gravity acceleration data through the Euler Angle algorithm was eliminated and the index calculation software platform was developed, the computation and data storage from raw data to the index parameter were implemented.Through the data analysis of the trainees′ 10 times training operation, it shows that the operation time is reduced by 32% before and after the training, the average operating speed of both hands is reduced by 45% and 32% respectively, the stability is increased by 15% and 19% respectively,and the free rate is reduced by 53%.
