Mechanical teleoperated device for remote manipulation

A mechanical teleoperated device comprising: a slave unit (10) an end-effector (40) a master unit (20) and a handle (30). Mechanical transmission means are arranged to kinematically connect the slave unit (10) with the master unit (20) such that the movement applied on the master unit (20) is reproduced by the slave unit (10), and to connect the end-effector (40) with the handle (30) such that movements applied on the handle (30) are reproduced by the end-effector (40). The master unit (20) is able to rotate about its longitudinal axis (theta1) and about axes (theta2, theta3), which always intersect at a stationary single point (32'). The corresponding slave unit (10) rotates about its longitudinal axis (theta4) and about axes (theta5, theta6) which are parallel respectively to said second and third axes (theta2, theta3), which always intersect at a virtual stationary single point (50).
