    Abstract:

    Acupuncture is a practical discipline,and the experience of operational training is very important for acupuncture medical students to master acupuncture techniques. To address the problems of low accuracy and realism of traditional training methods, this article establishes a virtual acupuncture training platform based onTouch X and unity. The force model is formulated by collecting data from the needle punched pork experiment and the lifting and twisting techniques. For the insertion method, the whole model is divided into two parts,including penetration force modeling and insertionforce modeling. Compared with the existing penetration force model, this article adds attenuation force modeling,which makes the layering sense of the needle punching process more realistic. The Karnopp model is used to solve the damping function per unit length of different tissue layers. Finally, the formula method is used to combine the penetration force and the insertion force to establish a complete mana model of the insertion. The data-driven modeling is used for the twisting maneuver,which is divided into two parts,including dynamic twisting and static decay. Both of them have test set accuracy values of 0.985 08 and 0.992 49,respectively.Finally,the model is evaluated by left-right hand comparison experiment and user perception experiment. The results show that the two acupuncture manipulative models have high accuracy,strong authenticity and good scalability.
