Development of a real catheter-based force feedback system

Catheter operations are actually common in the medicine field. The development of new medical equipment becomes essential. These operations request high skills and surgeons have to be trained for operations. Efficients catheter manipulating systems already exist for tele-surgery but they can't create the same feeling as a classic operation. According to the needs of surgeons, this study propose a new manipulating system witch it uses a real catheter. At first, a photographic sensor will be used to get the translation and the rotation of the catheter without friction. Then an haptic device will be designed to change the feeling of the surgeon. A stepping motor couple with a pulley system will change the pressure on the catheter and then change the manipulating feeling. At last some experiments will be done for verified the characteristics of the system.
