  • Patent number: 11430139
    Abstract: The invention relates to a registration method for determining position and orientation of an object in relation to a position detection system, wherein the method comprises the steps of capturing an image of a surface of an object with an image sensor unit comprising at least one motion sensor and/or at least one position sensor, determining a capturing position of the image sensor unit in a coordinate system of the position detection system by processing motion sensor signals provided by said motion sensor and/or position signals provided by said position sensor, photogrammetrically generating a surface model of the object from the captured image, and transforming the photogrammetrically generated surface model into the coordinate system of a position detection system.

  • Patent number: 8221406
    Abstract: A high frequency current application apparatus for thermal sclerosing of body tissue, comprising a high frequency generator connected to at least two electrodes, one of which is to be introduced into body tissue. The apparatus includes a measuring and calculating device adapted to ascertain impedance (or ohmic resistance) between the two electrodes between which a respective therapeutic high frequency current flows. A control device is connected to the measuring and calculating device for varying the output power. During high frequency current application the measuring and calculating device forms the first derivative with respect of time of the impedance. The control device reduces output power when that derivative exceeds a positive threshold characteristic of a threat of tissue desiccation and restores output power to the original power when the first derivative exceeds in positive values a negative threshold characteristic of adequate rehydration of body tissue.

  • Patent number: 8216219
    Abstract: An electrode array is used for the thermal schlerosing of body tissue. The electrode array has at least three active electrodes that, during use, are placed in electrical-conducting connection with body tissue. A high frequency generator is electrically connected for selective application of current to the active electrodes for producing a high frequency voltage. A measuring device measures impedance of the tissue between the active electrodes. In addition, a selector device selects a sub-array including at least two active electrodes from the electrode array, the selecting being effected on the basis of the measured impedance. Further, a control device is configured such that a high frequency voltage is respectively applied between the active electrodes of the selected sub-array in such a way that a high frequency current flows between the selected active electrodes through the body tissue.

  • Patent number: 7828799
    Abstract: The disclosure provides a probe arrangement having a distal probe tip and a proximal hand portion for the electrothermal coagulation of tissue. The probe arrangement has at least a first and a second electrode in the region of the distal probe tip. An inner conductor of the probe arrangement extends from the distal probe tip to the proximal hand portion and contacts the first electrode in the distal probe tip. An outer conductor of the probe arrangement extends from the distal probe tip to the proximal hand portion and serves to electrically contact the second electrode in the distal probe tip. The inner and outer conductors of the probe arrangement are electrically insulated from each other. Furthermore the inner conductor is selected in such a way that the flexural stiffness of the probe arrangement is increased between the probe tip and the hand portion.

  • Publication number: 20060271031
    Abstract: The invention relates to a surgical probe comprising a handle and a shaft that is connected to the handle, and two axially interspaced electrodes, the electrode closer to the handle forming a proximal electrode and the other electrode further from the handle forming a distal electrode, said electrodes respectively forming an outer surface of the shaft and being separated by an insulator. The outer diameter of the two electrodes and the outer diameter of the insulator are approximately the same and the shaft has a fluidic passage for a cooling fluid, which extends inside the shaft, from the handle to the distal electrode. The inventive surgical probe is characterised in that the shaft comprises a single-component hollow body that is connected to the handle, forms the distal electrode, and carries the insulator, the proximal electrode and an insulation layer arranged in the radial direction between the hollow body and the proximal electrode.
