Abstract
This paper presents a method of detecting the resistant force that acting on the guide wire when it moving into the body blood vessel for minimally invasive cardiovascular interventional surgery operated by a robot system. To learn more about the influenced factors for measured force, some simulations of body blood flow environment have been given. And then some analyses have been worked on blood flow to study whether the parameters of blood flow influence the resistant force measurement results. All of these studies will make us know more about the reliability of this force detecting method and lay the foundation for realizing force feedback in minimally invasive surgery robot system to further improve the system reliability.
