Device for adaptation of in particular surgical instruments such as pointing devices

摘要

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.
