摘要:
The invention relates to a device and a method for transcranial, non-invasive, electrical deep-brain stimulation, of the kind used in particular in the treatment of neurological and psychiatric disorders and of disturbances of the motor/cognitive functions in the human brain, wherein the device has at least one signal generator for generating an electrical alternating-current signal, an electrode arrangement, which can be placed on the head of a person to be treated and can be connected electrically to the signal generator so as to apply an alternating-current signal, wherein the electrode arrangement can be used to apply at least two alternating-current signals, of which the trajectories cross the region of the brain to be treated, such that their alternating currents are superposed, as a result of which the region of the brain to be treated is stimulated by electrical alternating currents in a targeted manner, whereas adjacent regions of the brain are stimulated only slightly or not at all.

The invention relates to a device for the adaptation of in particular surgical instruments, such as pointing devices. Said adaptation device comprises a magnetic field sensor or the like, a receiver device for a surgical instrument and a locking option for said surgical instrument. Said receiver device, which is associated with the respective surgical instrument and exclusively adapted thereto, permits a precise positioning of said instrument in relation to the sensor by means of a locking device. Said locking device as well as the receiver device design prevent an unintentional loosening or a displacement of the surgical instrument in the receiver device. A time consuming recalibration of said magnetic field senor on assembling and disassembling the surgical instrument is thus avoided.

The invention relates to a device for localizing tracking bodies (10), comprising at least one tracking body which is placed inside a physiological structure, and a means which is situated outside of the structure and which consists of sensor clusters (20) in a sensor cluster arrangement (55) as well as a method for localizing and influencing the tracking body. The tracking body is provided in the form of a body which is characterized by a finite remanent magnetization with a variable magnetic dipole moment and an anisotropic magnetic dipole field resulting therefrom. The sensor clusters (20) are provided in the form of a plurality of gradiometer sensors (30) with a specific measuring geometry. Optionally, physical/chemical properties and/or a trajectory of the tracking body may be altered in a specific manner by an externally acting magnetic field (H) and/or physiological processes in the environment of the at least one tracking body. In addition, it is possible to detect the location of a variable, in particular, a displaceable portion (57) which is associated with an expanded imaging means (60) of the sensor cluster arrangement (55) by means of a fixed portion (56) of the sensor cluster arrangement and to use the variable portion of the sensor cluster arrangement as a site marking in the expanded imaging arrangement.
