A novel vibrating device for the interventional surgical Robotic System

At this time, centrum cerebrovascular diseases (CCVd) have been a serious threaten to human being's health. Compared with traditional therapeutic method for treating CCVd, the vascular interventional surgery is like to be accepted by patients and clinicians now because it can reduce patients' pain and permit a faster recovery, and it's more like to be used in treating cerebral vascular diseases rather than only in the therapeutic areas of cardiovascular diseases, which needs more accuracy and convenience of the medical equipment. As we know, the blood is very viscous, and there is many friction when the catheter moving in the blood vessel, and many other reasons that impede the catheter move. So we should find some way to avoid this situation. Adding vibration to catheter is a good way for this problem. Therefore, it is essential to realize that it's very meaningful to find out a new method and design a novel device to add vibration to the catheter in the vascular interventional surgery. This paper proposes a new method that guide the catheter with micro vibration, and design a novel device to realize it after studying on vibration of the piezoelectric plate. It is shown that the novel device can conduct the vibration to the catheter well, and it can be the basis of our further research.
