    摘要： A motor/active magnetic bearing combination includes two stator base plates made of magnetic material. A plurality of sets of north and south poles, numbering at least three are formed on each of the stators, and each set comprises one or two south poles and a north pole or vice versa. Appropriate energization of the coils surrounding each of these poles both suspends and creates a magnetic field which imposes a constant speed rotation on the rotor which is suspended between the stators. The rotation is achieved by virtue of the fact that the rotor includes a circumferential set of slots defining regions around the circumference which interact with the energized poles on the stator so that a reluctance motor is formed, driving the rotor in rotation.

    摘要翻译： 电动机/主动磁轴承组合包括由磁性材料制成的两个定子基板。 在每个定子上形成多个组合的至少三个的北极和南极，并且每组包括一个或两个南极和北极，反之亦然。 围绕这些极点周围的线圈的适当通电都悬挂并产生磁场，该磁场在悬架在定子之间的转子上施加恒定的速度旋转。 旋转是通过以下事实实现的，即转子包括限定围绕圆周的区域的周向组的槽，其与定子上的通电极相互作用，从而形成磁阻电动机，以驱动转子旋转。

    摘要： An external manipulator for positioning surgical instruments within the abdominal cavity, comprising a hybrid kinematics with a parallel structure, able to provide four, active or passive, positional degrees of freedom to a endoscopic unit, placed in the distal end of an instrument shaft. Due to this specific kinematics, the instrument shaft is able to perform two rotations, one translation, and a fourth orientation degree of freedom about a remote centre of rotation, coincident with the surgical incision port. Because of its unique design and kinematics, the proposed mechanism is highly compact, stiff and its dexterity fulfils the workspace specifications for surgical procedures.

    摘要： A novel mechanical system, based on a new cable driven mechanical transmission, able to provide sufficient dexterity, stiffness, speed, precision and payload capacity to actuate multi-DOF micro-manipulators. Besides the possibility of being used in several articulated surgical instruments and robotic systems for surgery or other applications involving remote manipulation, it enables the design of a novel fully mechanical surgical instrument, which offer the advantages of conventional laparoscopy (low cost, tactile feedback, high payload capacity) combined with the advantages of single port surgery (single incision, scarless surgery, navigation through several quadrants of the abdominal cavity) and robotic surgery (greater degrees of freedom, short learning curve, high stiffness, high precision, increased intuition). The unique design of the proposed system provides an intuitive user interface to achieve such enhanced manoeuvrability, allowing each joint of a teleoperated slave system to be driven by controlling the position of a mechanically connected master unit.
