Abstract: A surgical instrument for bonding body tissue includes a shank and first and second tool elements which are movable relative to each other and include a respective electrode. The electrodes define a minimum distance from each other, are opposed to each other and face each other in an approximating position of the tool elements. The first tool element is arranged or formed at the distal end of the shank, so that a mechanical load of anastomoses of body tissue parts produced by current flow is minimized when removing the surgical instrument. The second tool element is adapted to be brought from an operating position, in which it can be brought into the approximating position, into a removing position, in which a peripheral withdrawing line defined by the electrode of the second tool element is shorter than a peripheral approximating line defined by the electrode in the approximating position.

Abstract: An electrosurgical instrument for making an end-to-end anastomosis between two hollow organ sections includes two tools movable relative to each other and each including an HF electrode by which the hollow organ sections can be fusion-welded to each other.

Each jaw member has at least one electrode connectable to an electric power source and electrodes of both jaw members being adapted to interact for sealing body tissue held between the jaw members in the gripping position, actuating means for transferring the jaw members from the opening position into the gripping position and means for limiting the closing width of the jaw members, when they are transferred from the opening position into the gripping position.

Abstract: A surgical system for connecting body tissue is provided. The surgical system includes 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, define a minimum distance from each other, lying opposite each other and facing each other. The instrument has a shaft at the distal end of which at least a first one of the tool elements is arranged or formed. A second tool element is movable 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 a shaft direction in a region of the second tool element is smaller in the removal position than in the operating position.
