A medical bending system for bending an object to be bent, in particular a rod, includes at least one object to be bent, a bending apparatus with which the object to be bent is bendable, and a navigation device having a detection unit and a data processing unit. The object to be bent and the bending apparatus include markings that are optically detectable by the detection unit and are arranged or formed on respective surfaces of the object to be bent and the bending apparatus. The data processing unit determines at least one bending parameter during the bending operation based on information from the detection unit relating to the detected markings.

The invention relates to a medical instrumentation with a navigation system which comprises an optical detection unit comprising a camera, and a data processing unit coupled to the detection unit, with a medical article and with a marking device which is held directly or indirectly on the article and is positioned in a defined spatial arrangement in relation thereto, or which marking device is comprised by or formed by the article, the location and orientation of the marking device being determinable with the navigation system, it being possible for at least one image of the marking device and the article to be taken by means of the detection unit and for the position and shape of the article to be determined by the data processing unit on the basis of an image. The invention also relates to a method for determining the shape of a medical article.

Medical instrumentation and method

The invention relates to a medical deformation device for a medical article, said deformation device comprising a receptacle for fixing the article, a deformation tool used to act on the article for deformation purposes, the deformation tool being movable in a defined manner relative to the receptacle, and a medical marking device that is detectable by a navigation system is held in each case on the receptacle and on the deformation tool for the purposes of determining a relative position of the deformation tool and the receptacle, wherein a further marking device is fixed to the deformation tool for the purposes of determining, by means of the navigation system, an extent of a deformation of the article. Moreover, the invention relates to a deformation system and a method for deforming a medical article.

The invention relates to a medical instrumentation with a navigation system which comprises an optical detection unit comprising a camera, and a data processing unit coupled to the detection unit, with a stabilization element of a surgical fixation system and with a medical marking device which is held in a defined spatial arrangement on or is comprised by or formed by the stabilization element, the location and orientation of the marking device in space being determinable with the navigation system, it being possible for at least two images of the stabilization element and the marking device to be taken from a different orientation by means of the detection unit and for the shape of the stabilization element to be determined by the data processing unit on the basis of the two or more images. The invention also relates to a method for determining the shape of a surgical stabilization element.

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.

Medical instrumentation including a navigation system

Medical instrumentation includes two or, in particular, more anchoring elements for anchoring on body tissue, and a stabilization element via which the two or more anchoring elements are connectable. The instrumentation includes a sensor unit, a coupling unit for percutaneous selective coupling of the sensor unit to at least one anchoring element or to the stabilization element, and a data processing unit which determines from sensor signals of the sensor unit the position of the anchoring elements relative to one another and/or the position of at least one anchoring element relative to the stabilization element.

An orthopaedic fixation system includes an anchoring element, which can be anchored to a bone and can be connected to a further anchoring element by means of a stabilization element. The anchoring element may include a stabilization element seating, into which the stabilization element can be guided. The orthopaedic fixation system may also include an extension device for the anchoring element having a longitudinal extent with a proximal section and a distal section. The distal section can be detachably fixed to the anchoring element. The fixation system may further include a holding device with a probe seating for an extracorporeal ultrasound probe and a coupling device for coupling the holding device to the proximal section of the extension device. A targeting device for a fixation system and an orthopaedic fixation method are also described.

An apparatus for recording the contour of a surface of a body is provided in accordance with the present invention. The apparatus comprises a carrier on which at least one distance measuring element is disposed. The at least one distance measuring element is capable of determining a distance between the carrier and a location on the surface of the body. A navigation system with marking elements is provided. The marking elements are fixable on the carrier and on the body, such that positional data regarding the position of the body and the carrier can be determined by the navigation system. A data-processing device device is also provided, which is adapted to calculate the contour of the surface from the positional data of the body and of the carrier and the distance measurements of the at least one distance measuring element.
