The invention relates to an instrument for use in computer guided surgery. The instrument includes a shaft and a reference element adapter, wherein the reference element adapter is directly couplable to the shaft and rotatable about the shaft. A selectively operable mechanical retainer provides retention of the reference element adapter to an instrument shaft adapting interface of the instrument shaft. The instrument also includes a reference element orientating mechanism arranged at an interface between the instrument shaft adapting interface and the reference element adaptor. The reference element orienting mechanism is capable of fixing at least one angular position of the reference element. The instrument also includes a grip piece interface on the instrument shaft, and a grip piece is selectively couplable to the grip piece interface.

Universal instrument or instrument set for computer guided surgery

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.

Method and device for registering a femur implant

A method for registering a non-patient-characteristic three-dimensional magnetic resonance data set (MR data set) to patient-characteristic data includes: producing or providing a non-patient-characteristic three-dimensional generic model of a body or body part containing body structure data; ascertaining or providing two-dimensional patient-characteristic detection data of a patient; using a transformation protocol for data-linking the body structure data of the three-dimensional generic model to the two-dimensional patient-characteristic detection data to change or adapt the generic model of the body or body part based on the ascertained two-dimensional patient-characteristic detection data, wherein the three-dimensional generic model is at least correlated with a three-dimensional MR reference data set; and changing or deforming at least a part of the three-dimensional MR reference data set by using the transformation protocol to generate a patient-characteristic three-dimensional MR data set that is registered to the fluoroscopic images.

Registering MR patient data on the basis of generic models

A vertebral spreading instrument for moving apart two vertebrae of a spine includes a plurality of spreading fingers and a spreading mechanism for adjusting a distance between the spreading fingers. The spreading mechanism includes a first and a second part, the first and second parts each including a respective marker trackable by a navigation system. Relative positions of the first and second parts change when the distance between the spreading fingers is adjusted, and different relative positions are unequivocally assigned to different distances of the spreading fingers.

Vertebral spreading instrument comprising markers

A method for computer-assisted medical navigation and/or pre-operative treatment planning includes detecting the current position of a patient or a part of a patient's body and the positions of medical treatment devices or treatment-assisting devices. The detected positional data can be assigned to body structure data, in order to jointly use the body structure data in assignment with the positional data, within the context of assisting the treatment. The body structure data can be used which is obtained based on a three-dimensional generic model, where the model is adapted by two-dimensional data linking with patient-characteristic, two-dimensional detection data.

Planning and navigation assistance using two-dimensionally adapted generic and detected patient data

A fixing system and method for fixing a navigational reference array for image-assisted medical treatment with respect to a patient, wherein the reference array is arranged the patient's body with the assistance of an immobilizing device, and wherein the immobilizing device is a vacuum mattress or a vacuum mattress patient jacket, and at least one anchoring for the reference array is provided on or in the vacuum mattress or a vacuum mattress patient jacket.

Non-invasive system for fixing navigational reference

A system for visually combining patient image data from transillumination and/or tomographic imaging methods and/or object image data with video images includes an image display device having an auto-stereoscopic monitor, at least one camera and a computer-assisted navigation system. The navigation system is operable to detect spatial positions of a part of the patient's body via a first tracking device attached to the body, and spatial positions of said image display device and/or said at least one camera via a second tracking device attached to the image display device or the camera, wherein the image display device and the at least one camera are assigned to each other and are formed as a portable unit.

Stereoscopic visualization device for patient image data and video images

A method and device generating a computer tomography data set CT* of an object, wherein a nuclear spin tomography recording MR of said object is obtained, and a transformation or mapping protocol f(MR) for a nuclear spin tomography reference data set MRis ascertained. The nuclear spin tomography reference data set MRcan be mapped onto said recorded nuclear spin tomography data set MR, wherein said ascertained transformation or mapping protocol f is applied to a computer tomography reference data set CTcorresponding to the nuclear spin tomography reference data set MRto determine a virtual computer tomography data set CT*=f(CT).

Method and device for generating a CT data set

A device for visually combining patient image data from transillumination and/or tomographic imaging methods with object image data comprising video images includes an image display device and at least one video camera associated with the image display device as a portable unit. A computer-assisted navigation system can detect the spatial positions of the image display device and/or the video camera as well as the spatial positions of a part of the patient's body via tracking means. An input device can be provided on the image display device, which enables inputs for image-assisted treatment or treatment planning.
