The software design for a medical robot for urological applications

Safety and reliability are the crucial requirements of the software for a medical robot which is a safety-critical system. Based on the verification and validation of a commercial prototype medical robot, the surgeon programmable electrical TURP, a software design method for medical robot was put forward. It was proved that it can help improve the quality of the software. The concepts of software levels, surgeon robot interfaces and error processing were also considered. These methods are being adopted in the development of a new robot, which could provide the common platform for interstitial laser coagulation and radiation seed implantation of the prostate.
