The present application relates to an endoprosthesis including a first member which is connected to a patient's bone; a second member which is adjustably coupled to the first member by a coupling device; wherein the coupling device is configured to generate a movement of the second member relative to the first member. The present application also relates to an artificial joint including such an endoprosthesis and to an endoprosthesis placement system including such an endoprosthesis or artificial joint and a projection device which is configured to project visible light markings, acquired from pre-operational and/or intra-operational patient data, onto the patient and/or the endoprosthesis, thus enabling visible alignment markings of the endoprosthesis to be aligned with respect to projected visible light markings so as to allow a proper adjustment of the endoprosthesis.

Adjustable endoprosthesis

A device and method for detecting an impingement of joint components of a joint includes detecting a spatial position of each joint component during a relative movement of the joint components; calculating an instantaneous center point of rotation or an instantaneous axis of rotation from the detected spatial positions of the joint components; when one joint component moves relative to the other joint component, establishing whether the calculated instantaneous center point of rotation moves within a first expectation range or whether the calculated instantaneous axis of rotation moves within a second expectation range; and establishing that there is an impingement of the joint components when at least one of the calculated instantaneous center point of rotation or the calculated instantaneous axis of rotation leaves or exits the respective expectation range.

Method and device for detecting and localising an impingement of joint components

A marker navigation device for determining and/or tracking a location of a marker device is provided. The marker device is attachable to an object, said marker device including a plurality of markers having known dimensions and being in a known positional relationship relative to each other. The marker navigation device includes: a detection device operative to detect signals emitted by or reflected from the plurality of markers, wherein the detection device is formed such that in first locations of the detection device relative to the marker device, detection of signals from one marker of the plurality of markers is restricted or impossible due to a location of another marker of the plurality of markers. In second locations of the detection device relative to the marker device, the plurality of markers are detectable by the detection device. The navigation device also includes a processing device communicatively coupled to the detection device and configured to calculate the first locations based on the relative locations of individual markers of the plurality of markers and based on the known dimensions of the plurality of markers, and calculate an actual location of the marker device relative to the detection device based on detected signals from at least one marker of the plurality of markers, the known locations of the plurality of markers relative to each other, and the known dimensions of the plurality of markers. The processing device also can determines whether the actual location of the marker device is one of the first locations. A warning device is communicatively coupled to the processing device and operative to output a warning signal when the actual relative location is one of the first relative locations.

Marker navigation device

A system for applying an element to a body, wherein the position of a device for preparing and/or producing a connection between said body and said element relative to the position of said body is detected, it also relating to a system for applying an element to a body comprising a device for preparing and/or producing a connection between said element and said body and a position detection device for detecting the position of said device, for preparing and/or producing a connection between said element and said body, and for detecting said position of said body.

System for the navigation-assisted positioning of elements

The invention relates to a device ( ) for determining the position of an incision block ( ) comprising: a positioning element ( ) with at least one reference point ( ), whose spatial position can be detected; and a position determining element ( ) which is firmly connected to the positioning element ( ), as well as to a method for determining the position of an incision block, wherein: the location of a positioning element ( ) on a body structure, in particular on a bone, is detected; the location of a positioning element ( ) for positioning a position determining element ( ) is detected; and the relative location of an incision block ( ) to the body structure is determined from the location of the positioning element ( ) and the location of the positioning element ( ).
