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 method for providing positional relationship data, which represent the position of a marker device relative to a bone which it is affixed to, to a medical navigation system, including receiving bone registration data which represent locations of points on the surface of the bone, calculating, from the bone registration data, the current relative position between the bone and a medical instrument which bears the marker device, determining an offset between the current relative position and a desired relative position; outputting indication information which is based on the calculated offset, receiving bone re-registration data which represent locations of points on the surface of the bone, and calculating the positional relationship data from the bone re-registration data.

Method for enabling medical navigation with minimised invasiveness

A method for providing positional relationship data, which represent the position of a marker device relative to a bone which it is affixed to, to a medical navigation system, comprising the steps of: a) receiving bone registration data which represent locations of points on the surface of the bone; b) calculating, from the bone registration data, the current relative position between the bone and a medical instrument which bears the marker device; c) determining an offset between the current relative position and a desired relative position; d) outputting indication information which is based on the calculated offset; e) receiving bone re-registration data which represent locations of points on the surface of the bone; and f) calculating the positional relationship data from the bone re-registration data.

The present invention relates to a method for determining the mechanical axis of a bone using an electronic device which is rigidly attached to the bone and comprises a video camera, wherein:

The invention relates to a medical instrument, comprising a signal transmitter and at least one activating device for activating the transmitter which is provided on a transmitter unit which is separate from the instrument, wherein the transmitter unit is a unit which can be fastened to the exterior of the instrument. It also relates to a method for controlling a treatment-assisting medical software by means of a signal transmitter which is arranged on a medical instrument, wherein the instrument is positionally detected by means of a medical tracking system, and wherein the software assigns a different significance to the signal output by the transmitter depending on the position of the instrument.

Medical instrument comprising a separate transmitter unit which can be exteriorly fastened

The present application relates to a tool for detecting planes which are defined by anatomical landmarks, comprising a first and a second level abutment area for placing onto a body structure, wherein the first and second abutment areas have a predetermined position relative to each other, and comprising a tool marker device which has a stationary position relative to the first and second abutment areas.

Tool for detecting planes of a bone and assigned data processing method

The present application relates to a surgical connecting device for connecting a first and second cutting block which each serve to make an incision on a first and second anatomical structure, comprising: a first attaching section for attaching the surgical connecting device to the first cutting block by a mechanical connection; a second attaching section for attaching the surgical connecting device to the second cutting block by a releasable mechanical connection; and a spacing section which spaces the first attaching section away from the second attaching section.

Connection of cutting blocks

The present invention relates to a device for positioning a jig at a structure using at least one fixing element comprising at least one adjusting element which can directly interact with or guide the at least one fixing element and which can interact with the jig, so that the relative position between the at least one fixing element and the jig can be adjusted by changing the position of the at least one adjusting element, as well as to a method for positioning a jig at a structure comprising two rotatable adjusting elements, wherein the resection plane of the jig can be moved along or in a first direction when the adjusting elements are moved in the same direction and wherein the resection plane is turned if the adjusting elements are moved in an opposite or different direction or only one adjusting element is moved.

A method for planning a bone implant ascertains a condition of a bone to be treated, and identifies a dysfunctional part of the bone. A free-form area then can be ascertained and registered, wherein the free-form area lies below the dysfunctional part. A control data set then is produced that forms the basis for ablating the bone on the ascertained free-form area.
