A force display method for a novel catheter operating system

We have developed a force display method for a catheter operating system in this paper. We designed micro force sensors and used them in the system to ensure the operation security in intravascular neurosurgery applications. We also used camera to monitor the situation of simulation experiment, and used developed force display system to monitor the changed force that catheter contacted with blood vessel. We carried out the operation simulation experiments and obtained the force information by the force sensors when the catheter contacted the blood vessel. The experimental results indicated that the proposed force display system for a catheter operating system works well and can improve the safety of Master-slave system, and also the force feedback can effectively improve operability, in addition, the developed system can avoid danger automatically.
