Abstract: A method for measuring temperature includes emitting light with an illumination spectrum into a tissue with at least one illumination, receiving the remission of light with a remission spectrum from the tissue using at least one detector, converting the remission spectrum into a detector signal, sending the detector signal to a calculating unit, calculating a first theoretical remission spectrum based on a solution for describing the propagation of light in the tissue with the calculating unit, assuming estimated volume fractions of the individual tissue components, adapting the theoretical remission spectrum to the measured remission spectrum, and calculating at least one volume fraction of a tissue component from the remissions spectrum using a minimization algorithm, which is used by the calculating unit to adapt the theoretical remission spectrum to the measured remission spectrum using variations in the volume fractions of the individual tissue components which are present in the tissue.

Abstract: A receiving sleeve of a tool set includes a hollow body having an end face with an insertion opening for inserting a tool. The hollow body defines a longitudinal central axis and includes a plurality of inner clamping elements spaced apart in a circumferential direction. The clamping elements have punctiform or linear engagement sections at their free, radially inward protruding end portions. The engagement sections make force-fit and/or form-fit contact with the tool for holding the tool within the receiving sleeve at a radial distance from the hollow body. An inner side of the hollow body has circumferentially spaced rigid protrusions that extend axially in rib-like fashion. The inner clamping elements radially protrude further toward the longitudinal central axis of the hollow body than the rigid protrusions.

Abstract: A method of applying at least one coating of at least one electrically insulating polymer to an applicator for currents, especially HF currents in surgery, the coating is produced by electrophoretic deposition from a suspension of the polymer in at least one organic solvent, wherein the applicators thus coated are especially clamps, pairs of tweezers or pairs of scissors which are used in the bipolar application technique of HF surgery. Polymers used are especially thermoplastic polymers, such as thermoplastic fluoropolymers, and more particularly polychlorotrifluoroethylene (PCTFE) or ethylene chlorotrifluoroethylene (ECTFE).
