About 90% University Hospitals have navigation system. The main purpose to use navigation system is to distinguish where the target points are. Now, navigation system is classified into an optical type and a magnetic field type according to the system of a position detection system, and an optical type is the present mainstream.
An optical type has a fault to which position recognition becomes poor by direction of probe, while there is an advantage that the possibility of interference with operation apparatus is low.
On the other hand, although there is an advantage which can recognize a position regardless of direction of probe by a magnetic field area, there is possibility of a magnetic interference with operation apparatus.
In our hospital, Stealth Station S7: hybrid form navigation system is used from 2011. The hybrid type has the system of both an optical type and a magnetic field type, and it is possible to choose a system according to a situation.
Based on use experience, the advantage and disadvantage of hybrid type navigation system were examined.
