Abstract: A surgical instrument and use of a surgical instrument in open surgery. The instrument has two gripping limbs and a blocking element that releasably locks the gripping limbs relative to one another. The blocking element has a female locking assembly and a male locking assembly. The female locking assembly has a mechanical control device for locking and releasing a locking portion of the male locking assembly. A mechanical control assembly is assigned to the male locking assembly and moves the locking portion of the male locking assembly out of an end position that defines a neutral position into an end position that defines a functional position and, conversely, out of the end position that defines the functional position into the end position that defines the neutral position. The control assembly includes securing elements that secure the locking portion in both end positions.

Abstract: 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.

Abstract: A bipolar sealing instrument includes a first actuating mechanism for manual actuation of a tool provided at a distal instrument tip at least in a low-load working force range. A second actuating mechanism includes an electric motor configured to be automatically activated when a high-load working force range is reached, in order to subsequently transfer the tool into a high-load working posture/position in a motor-assisted or fully automatic manner supporting the manual actuation.

Abstract: A surgical instrument includes an instrument shaft, two instrument branches that can be positioned relatively to one another in a working position and a rest position, a handle element on which an operating element is movably arranged for positioning the instrument branches, and a coupling mechanism having a translating unit that converts a movement of the operating element, non-linearly, into a relative movement of at least one of the two instrument branches. The coupling mechanism includes at least one bias element that biases the mechanism into the rest position and/or into the working position of the instrument branches.

Abstract: A surgical instrument includes a shaft portion which at least partly houses an axially movable cutting element. A handle receives the shaft portion. A trigger element for the cutting element is movably arranged on the handle. The instrument also includes a coupling mechanism which converts a rotation of the trigger element into an axial movement of the cutting element with the interposition of a pinion. The coupling mechanism is designed such that the rotation of the trigger element produces a rotation of the pinion about the central axis thereof and additionally an axial movement of the central axis.

Abstract: 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.

Abstract: An electrosurgical instrument includes mutually movable instrument legs each comprising one or more electrode faces between which tissue can be clamped and treated in electrothermal manner. The movement of the instrument legs relative to each other can be delimited by at least two spacers which are spaced from each other in the longitudinal direction of the instrument legs and act on the instrument legs. At least one electrode face portion subjected to deflection in a closed position of the instrument legs is formed to be bow-shaped, in particular concave, the curvature being contrary to the bending direction to be expected.

Abstract: 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.
