Medical navigation system with wirelessly connected, touch-sensitive screen

A medical system comprising:

• an instrument;
• an electromagnetic position acquisition apparatus for the instrument configured to acquire
• a position of the instrument in relation to a reference coordinate system;
• a computer configured to generate an image of a body part from currently recorded or stored data representing the body part, wherein the image reproduces a view of the body part together with a representation of the position of the instrument such that an observer can determine the position of the instrument in the body part from the image of the body part;
• and
• a user interface device selectable from a plurality of different user interface devices as being the user interface device of the medical system,
• wherein the user interface device is wirelessly connected to the computer and comprises a closed display on which one or more control elements are displayed, and on which the view of the body part and the representation of the position of the instrument are displayed during operation, wherein the user interface device is configured to accept user inputs via the displayed one or more control elements and to transmit control signals to the computer as a function of the accepted user inputs,
• wherein basic settings relating to representation manners for any one of the plurality of different user interface devices are stored either on one or more of the plurality of different user interface devices or on the computer, and wherein the basic settings are selected by one or more users of the medical system, and
• wherein the basic settings relating to representation manners for at least one of the one or more users are same across the plurality of different user interface devices independently of a specific operating system of any one of the plurality of different image user interface devices, and
• wherein the instrument is one of a plurality of instruments that are connected to the user interface device, wherein the electromagnetic position acquisition apparatus is further configured to switch between acquisition of a position of any one of the plurality of instruments that are connected to the user interface device, and wherein the user interface device is configured to switch between displaying a representation of any one of the plurality of instruments that are connected to the user interface device.
