LARS robot

One of the drawbacks of navigation systems is that they cannot guarantee that a planned surgical gesture, such as screw placement or needle insertion, will be executed precisely as planned. To ensure not only precise positioning but also precise execution, surgical robots have been developed. We describe next two examples of the most common types of active surgical robots the ROBODOC system discussed earlier and the LARS robot for percutaneous therapy.

Fig. 28.3. Close-up of biopsy experiment a robot (the IBM/ JHU LARS) holds the ultrasound probe and a second robot is used for positioning a needle guide. On both, an electromagnetic (EM) tracking system (Flock of Birds, model 6D FOB, Ascension Technology, Inc.) interfaces with the robot workstation. [Reprinted with permission from Boctor et al.
