A method for registering an asymmetrical femur implant having a shaft and a collar includes ascertaining a position of a shaft axis associated with the shaft and ascertaining a position of a collar axis associated with the collar. A device for registering an asymmetrical femur implant connected to at least one reference marker is provided. The device includes a detection device for detecting a spatial position of the at least one reference marker and a database in which a geometry of the asymmetrical femur implant is stored. A processor ascertains the spatial position of the asymmetrical femur implant.

A device and method for registering a patient's hip, wherein the device includes markers and positioning elements which can be placed on characteristic points of the hip, and once placed on characteristic points of the hip, data for registering the hip can be ascertained from the position of the markers. The method includes detecting the position of the markers arranged on the device and ascertaining data for registering the hip.

Registering intraoperative scans

A method for registering an anatomical structure using at least one marker attached to the structure includes: obtaining a three-dimensional model of the structure via an imaging method; obtaining at least two two-dimensional recordings of the structure from different angles; and ascertaining a spatial position and location of the three-dimensional model or a position and location of the three-dimensional model in a patient coordinate system based on a matching method that uses the position of the at least one marker in the at least two two-dimensional mappings such that the three-dimensional model of the structure matches the structure.

The invention relates to a device for assessing the applied air pressure during automatic respiration through positive airway pressure. The air pressure applied is varied by the device according to the invention so that at least three different pressure values can be adjusted. The corresponding respiratory gas flow is measured. On the basis of the relation of the measured respiratory gas flows to each other it is determined whether the applied air pressure is below or above an optimal air pressure or whether the applied air pressure is the optimal air pressure. The device according to the invention can be applied for adjusting the optimal air pressure in respirators used in the CPAP therapy. The device according to the invention provides the advantage of enabling an easy and reliable control of the applied air pressure.
