A medical instrument with a distal and a proximal end. A first tool element and a second tool element are arranged or formed on the distal end so as to be movable relative to one another. The tool elements define a tool element direction of extent from proximal to distal. The first tool element defines a first tool element face and the second tool element defines a second tool element face. The first tool element face and the second tool element face face toward one another. The tool elements define in the region of their tool element faces a width. The widths extend in a direction transverse to the tool element direction of extent and transverse to a surface normal of the first tool element face and/or the second tool element face.

Medical instrument

Surgical tissue fusion instrument and support structure having two gripping structures which are movable relative to each other and which are designed to bring together biological tissue sections that are to be connected to each other, with heat-generating means which are assigned to the gripping structures and, during tissue fusion, cause heat to be introduced in the area of a connection site of the biological tissue sections, and also with a support structure which is held between the gripping structures and, during tissue fusion, is operatively connected to the tissue sections. The support structure has at least one additional physical functional structure for aiding or promoting the tissue fusion.

An HF surgical instrument includes two instrument branches movable toward each other into a closing position. Each branch is equipped with at least one electrode and can be supplied with electric power from a power source. The HF instrument includes a separately configured bridge which is connectable to the power source via at least one electric connection or at least one electric line and includes at least one electrically conductive contact point for supplying the at least one electrode with electric power. The bridge can be introduced to at least one of the two branches so that the at least one contact point is electrically contacted by the at least one electrode. A method of assembling a HF surgical instrument includes equipping two instrument branches with at least one electrode.

HF surgical instrument

Surgical tissue fusion instrument having two gripping structures which are movable relative to each other, are designed for gripping and bringing together biological tissue sections, and are assigned heat-generating means designed in such a way that tissue fusion takes place between the biological tissue sections by heat being supplied in the area of the gripping structures. At least one gripping structure is assigned a fluid-conducting system, which is designed to supply at least one liquid or flowable additive to the tissue sections during a tissue fusion process.

Surgical tissue fusion instrument

A surgical instrument in HF design includes two tissue branches, at least one of the tissue branches being movable relative to the other tissue branch and being able to be applied to the other tissue branch with a predetermined or predeterminable contact pressure via an actuation mechanism while clamping body tissue between the tissue branches. A clamping pressure controlling or adjustment device is interconnected in a force or torque gear train between the actuation mechanism and the at least one movable tissue branch.

A bipolar RF sealing instrument includes two instrument branches which are movable relative to one another at least to an open and a closed position, and an instrument handle with two handle units, each associated with a respective instrument branch and coupled for manually operating the instrument branches and for applying to the instrument branches a predetermined closing force at the closed position, a first of the two instrument branches having a terminal for an external RF generator and the second instrument branch adapted to be electrically coupled via an instrument-internal power contact with the first instrument branch. The power contact may be a spring contact for contact closure at a closure position. In addition or alternatively, an instrument-internal control switch is present and only activated when the predetermined closing force is reached, to enable the supply of electric current from an external RF generator to the instrument branch(es).
