Abstract: Disclosed is a computer-implemented method for modelling human or animal patient tissue. The method includes: acquiring a stressed patient topography data set, the stressed patient topography data set describing a topography of at least one patient tissue surface under mechanical stress; determining an input data set; evaluating a statistic model for the input data set, thereby obtaining an output data set; determining, from the output data set, a relaxed patient topography data set. The statistic model includes a set of Gaussian Processes and is defined by a pre-determined model parameter set, the model parameter set including at least one Gaussian Process parameter for each Gaussian Process, and wherein the statistic model is independent from the patient tissue to be modelled. Disclosed is further a computerized device for carrying out such method. Disclosed are further a computer-implemented method and a computerized device for determining a parameter set.

Abstract: A suction and irrigation device for medical use comprises a valve body with an irrigation passage and a suction passage. At least one irrigation pipe and at least one suction pipe are connectable to the irrigation passage and the suction passage by connections at a proximal side of the valve body. A suction/irrigation tube is connectable to the irrigation passage and the suction passage at a distal side of the valve body by at least one further connection. A valve assembly is provided within the valve body, which in a first position opens the suction passage and closes the irrigation passage and in a second position closes the suction passage and opens the irrigation passage. The device comprises at least one push element which interacts with at least one movable element of the valve assembly, whereas the movable element is movable by mechanical force acted upon the push element such, that the push element activates the valve assembly from one position to the other position.
