Abstract: A surgical instrument comprised of a handle and a tubular shaft with an interior and a wall made from an electrically conductive material. A metallic wire is arranged at least in sections in the interior of the tubular shaft and can be moved by the actuation of a control element so that a loop that can be extended out of a distal end of the shaft is formed and with a switch, wherein the metallic wire can be energized by the actuation of the switch, in which the control element and the switch are coupled with each other so that the metallic wire is energized in defined positions of the metallic wire.

Abstract: A surgical instrument with a shaft is constructed as a hollow tube and has a longitudinal axis, proximal and distal ends and a metal wire having a first end section, a shaft section and a working section. The first end section is arranged in the area of the proximal end of the shaft or is guided out of the shaft on the proximal end. The shaft section is guided in the hollow tube and the wire is arranged such that it can move along the longitudinal axis of the shaft into a first position of the working section on the distal end projecting out of the shaft and into a second position of the working section within the shaft. The instrument is constructed as a bipolar instrument, wherein the metal wire is part of a first electrode and a second electrode is arranged in some sections on the shaft.

Abstract: A method for manufacturing a surgical instrument, comprising the steps of selection of a value for at least one parameter of the surgical instrument in a configuration program, automated generation of configuration data from the selected values by the configuration program, transfer of the configuration data to a 3D printer, and printing of the surgical instrument by means of a 3D printer.
