Considerations regarding the Application of Parallel Robots in the Surgery Field

Robotic systems have been developed in every field where a further progress was constricted due to the human limitations in terms of speed, precision, fatigue, repeatability, strength, safety etc. The two major types of robots, the serial ones (anthropomorphic, open-architecture) and the parallel ones (closed-loop mechanisms) have divided their spectrum of dominance in different applications based on their specific advantages. One of the pioneer fields for robots is their assimilation in surgery, especially in minimally invasive procedures which aim the treatment of a disease with minimum damage to healthy tissue and suffering for the patient. The authors present in the paper a critical analysis regarding the characteristics of a surgical robot for minimally invasive surgery, making a comparison between the serial and parallel robotic structures focused on the customized demands of the Operating Room. In the final part of the paper the authors will present some surgical robotic models which are currently studied at the Technical University of Cluj-Napoca.
