摘要：An actuator assembly is used in a surgical simulation system that simulates thecatheterization of cardiac or peripheral vasculature. The simulation system provideshaptic feedback to a user of a set of catheters or similar tubular objects coupled to thesystem. The actuator assembly is coupled to the objects, and also to a workstationexecuting a surgical procedure simulation program. The actuator assembly has a set ofspaced-apart actuators, each actuator being mechanically coupled to a correspondingobject through a rigid tube used as an extension of the object within the actuatorassembly. Each actuator in the assembly includes sensors that generate sense signalsindicative of axial translation and rotation of the object by the user. The sense signals areprovided to the workstation. In response, the workstation calculates axial forces andtorques to be applied to the object as haptic feedback to the user, and provides drivesignals to the actuator assembly.
