| 主权项 | 1. A method for operating a liquid jet scalpel, comprising the steps of: measuring a distance between a nozzle of the liquid jet scalpel and tissue which is to be manipulated, detecting a spatial position and orientation of the nozzle, computing a model of the tissue that is to be manipulated on the basis of the measured distance between the nozzle and the tissue that is to be manipulated and of the detected position and orientation of the nozzle; when the measured distance between the nozzle and the tissue shows a sharp decrease and a subsequent sharp increase, with said decrease and said increase exceeding a predetermined threshold value, it is assumed for computation of the model of the tissue that, at this site, there is situated a tissue that is to be preserved, which tissue, due to the selectivity in a cutting process performed with the liquid jet scalpel, has not been cut by the scalpel and thus forms an exposed bridge of tissue that is to be preserved, and wherein said bridge of tissue is included into the tissue model. | ||
