Abstract
The invention relates to a medical instrumentation, comprising a hand-held, integrated, medical navigation system which comprises an optical detection unit having a camera, a data processing unit and an optical display unit, the data processing unit being coupled to the detection unit and the display unit, it being possible for location and/or orientation data of a medical marking device which is detectable with the detection unit to be processed by the data processing unit and information relating thereto to be represented on the display unit, the instrumentation comprising an illumination unit with which light is emittable in the direction of the marking device detectable with the detection unit.
Claims17
Medical instrumentation, comprising:
- a hand-held, integrated, medical navigation system which comprises:
- a housing,
- an optical detection unit having a camera disposed in the housing,
- a data processing unit disposed in the housing,
- an optical display unit disposed in the housing,
- the data processing unit being coupled to the detection unit and the display unit, it being possible for location and orientation data of a medical marking device which is detectable with the detection unit to be processed by the data processing unit, and information relating thereto to be represented on the display unit,
- a sensor unit disposed in the housing for providing a signal relating to the inclination of the navigation system in at least one direction in space of an absolute reference system, and
- an illumination unit disposed on or in the housing with which light is emittable in a direction of the marking device detectable with the detection unit,
- two or more reference elements to be referenced,
- two or more medical marking devices, each of the two or more medical marking devices comprising a plurality of marking elements which are configured for retroflection of the light of the illumination unit,
- the data processing unit being configured to:
- determine a respective space vector between reference points referenced by the two or more medical marking devices, with one of the two or more medical marking devices being usable as a reference marking device for defining a reference coordinate system,
- determine an orientation of the space vector in the absolute reference system based on a signal of the sensor unit, and
- on the basis of the orientations of two or more of the space vectors, defining a plane in the reference coordinate system, and determine an inclination of the plane relative to the reference plane, in the absolute reference system,
- wherein:
- the two or more medical marking devices are adapted for selective coupling to the reference elements,
- a relative position of the reference elements is determinable by means of the data processing unit in the reference coordinate system,
- the reference elements are or comprise bone screws, and
- the two or more medical marking devices with extension elements are adapted for coupling percutaneously to the bone screws.
