Virtual surgery is an important application of virtual reality in medicine. Only the cutting-edge part of the surgical instrument contacts with the human organs in surgical procedures. Based on this characteristic, we proposed sampling a series of feature points from the organ's surface model of the body to describe the external contour of the organ, and then detect the contact state between the cutting-edge part of the surgical instrument and these points. Virtual sensor was built based on spring-mass damper model for haptic detection between the surgical instrument and human organ and tissue in virtual surgery environment. Realized the tactile and force interaction between surgical instrument and human organ model, as well as the force navigation in surgery.
