Structural Design of Prostate Biopsy Robot Based on TRIZ Theory

Abstract

In view of the problem of long period and low precision that generated by traditional prostate biopsy surgery at present, a special and miniature cartesian type robot for prostate biopsy was designed based on TRIZ theory, especially based on contradictory matrix and material-field analysis principle of TRIZ, therefore three-dimensional model of cartesian type robot of prostate biopsy was built, key components of the robot were designed by calculation .In conclusion the result indicates that the TRIZ theory can be applied to structural design of medical robot, and it also can solve the technical contradiction in design.
