In order to so improve a surgical system for connecting body tissue, comprising a surgical instrument having two tool elements movable relative to each other, each of which comprises a high-frequency electrode, the high-frequency electrodes, in an approach position of the tool elements, defining a minimum distance from each other, lying opposite each other and facing each other, that an overstretching of connections of parts of body tissue, in particular, made by a flow of current, is avoided when removing the surgical instrument, it is proposed that the instrument comprise a shaft at the distal end of which at least a first one of the tool elements is arranged or formed, and that a second tool element be adapted to be moved from an operating position, in which it is adapted for movement into the approach position, into a removal position and/or vice versa, a surface area of a perpendicular projection of the second tool element onto a projection plane extending perpendicularly to the shaft direction in the region of the second tool element being smaller in the removal position than in the operating position.
