A surgical system for use by a surgeon to perform-microsurgical techniques in a surgical area, the system comprising: a first mechanical telemanipulator comprising a first master unit coupled to a first handle , and a first slave unit coupled to a first surgical tool having a first end-effector , the first master unit kinematically coupled the first slave unit such that movement applied on the first handle by the surgeon is reproduced by the first end-effector ; a second mechanical telemanipulator comprising a second master unit coupled to a second handle , and a second slave unit coupled to a second surgical tool having a second end-effector , the second master unit kinematically coupled the second slave unit such that movement applied on the second handle by the surgeon is reproduced by the second end-effector ; wherein the mechanical telemanipulators have a size and configuration and are spaced apart to ensure a free line of sight between the eyes of the surgeon and the surgical area where the first and second surgical tools enter a patient's body; and a visualization system positioned to provide the surgeon the free line of sight between the first and second mechanical telemanipulators to the surgical area enabling the surgeon to visualise the surgical area where the first and second surgical tools enter a patient's body with the naked eye, wherein the visualization system permits the surgeon to be positioned in a balanced sitting position; characterized in that : the visualization system is configured to provide a magnified image of the surgical area to the surgeon, the surgical system being configured to allow the surgeon to view the surgical area through the visualization system and along the free line of sight between the first and second mechanical telemanipulators by movement of the surgeon's head and with the surgeon remaining in the same balanced sitting position. a first mechanical telemanipulator comprising a first master unit coupled to a first handle , and a first slave unit coupled to a first surgical tool having a first end-effector , the first master unit kinematically coupled the first slave unit such that movement applied on the first handle by the surgeon is reproduced by the first end-effector ; a second mechanical telemanipulator comprising a second master unit coupled to a second handle , and a second slave unit coupled to a second surgical tool having a second end-effector , the second master unit kinematically coupled the second slave unit such that movement applied on the second handle by the surgeon is reproduced by the second end-effector ; wherein the mechanical telemanipulators have a size and configuration and are spaced apart to ensure a free line of sight between the eyes of the surgeon and the surgical area where the first and second surgical tools enter a patient's body; and a visualization system positioned to provide the surgeon the free line of sight between the first and second mechanical telemanipulators to the surgical area enabling the surgeon to visualise the surgical area where the first and second surgical tools enter a patient's body with the naked eye, wherein the visualization system permits the surgeon to be positioned in a balanced sitting position; characterized in that : the visualization system is configured to provide a magnified image of the surgical area to the surgeon, the surgical system being configured to allow the surgeon to view the surgical area through the visualization system and along the free line of sight between the first and second mechanical telemanipulators by movement of the surgeon's head and with the surgeon remaining in the same balanced sitting position. <EOS>
