    摘要: Surgical devices are disclosed herein that generally include an intracorporeal elbow joint to facilitate translational movement of an end effector while allowing a body portion of the surgical device and a trocar or working channel through which the device is inserted to be maintained in a fixed angular orientation relative to the patient. This allows a plurality of such devices to be used effectively with a single incision or access device. Such devices also generally provide end effector movement with six degrees of freedom, while maintaining a mechanical linkage between the user and the end effector and while mimicking and/or mirroring natural user movement. Various methods related to such devices are also disclosed.

    摘要: A magnetic manipulation and navigation system for moving a magnetic element through a body comprising at least six electromagnets fixed in relation to said body and a control unit supplying the current for the electromagnets. The electromagnets have soft magnetic cores and the current supplied by the control unit to each of the electromagnets is adapted to operate the electromagnetic coils of each of the electromagnets in their core's linear regions being delimited by the value of the flux density of each electromagnet being in an interval between the negative and positive saturation value of each electromagnet, the lower representation showing the deviation due to the use of soft magnetic cores in all electromagnets.

    摘要: A coil system for the contactless magnetic navigation of a magnetic body in a work space, has a plurality of coils and a current controller for controlling the respective currents in the plurality of coils. In order to navigate the magnetic body to a variably predeterminable position in the work space, the current controller is designed such that the currents in the plurality of coils are such that the magnetic forces generated by the currents and acting upon the magnetic body at multiple positions at the edge of a convex environment around the predetermined position are directed into the environment. The coil system has the advantage that a movement of the magnetic body toward a spatial position is achieved without any mechanical movement of the coil system and without a positioning system for determining the position of the magnetic body. The coil system is utilized particularly in a medical device, wherein a magnetic body in the form of a probe is moved in the body of a patient. In this way, fast navigation of the probe in the patient's body can be achieved without mechanical movements of the patient table or of the coil system.

    摘要: A medical robotic system has a joint coupled to medical device or a slave manipulator or robotic arm adapted to hold and/or move the medical device for performing a medical procedure, and a control system for controlling movement of the joint according to user manipulation of a master manipulator. The control system includes at least one joint controller having a sliding mode control for reducing stick-slip behavior on its controlled joint during fine motions of the joint. The sliding mode control computes a distance to a sliding surface, computes a reaching law gain, and processes the distance and reaching law gain to generate a sliding mode control action that is in absolute value less that a maximum desired feedback control action. The sliding mode control action is then further processed to generate a feedback torque command for the joint motor.
