A kind of registration arrangement for medical navigation, it include: shape sensor device (SSD) (104,504), it has at least one sensor (450,505), at least one described sensor is used to provide the respective sensor information (SI) at least one position for indicating at least one sensor (450,505) Fixed device (106) are registrated, with channel (130), the channel is configured to receive at least part of SSD and defines registration path (P). The fixed device of the registration may be configured to be attached to the registration target (RO) (119) for defining working space. Controller (110) may be configured to: sense the shape in the path that SSD is passed through based on SI when at least one described sensor is within the channel (130) Determine whether the shape in sensed path is corresponding with the known form selected from one or more known forms And execute coordinate registration based on the determination.
