摘要：
The invention relates to a surgical system for connecting body tissue, comprising a surgical instrument with at least two tool elements, which are movable relative to one another and in each case comprise an HF electrode, which HF electrodes, in a position of approximation of the tool elements, define a minimum distance from one another, lie opposite one another and face one another, such that, when an HF current is applied, body tissue held between the tool elements is connected, and with a cutting element for cutting through and/or cutting off body tissue, which cutting element can be brought from a tissue-connecting position, in which body tissue can be connected to the tool elements and in which the cutting element cannot come into contact with body tissue, to a cutting position. In order to improve the said surgical system such that incorrect operation of the system is excluded as far as possible, it is proposed that the instrument comprises a safety mechanism for securing the cutting element in the tissue-connecting position. Moreover, an improved control method is proposed for a surgical system for connecting body tissue.
