Actuating element, surgical instrument, and method for manufacturing the actuating instrument

A force transmission element for a surgical instrument comprising:

• an electrically conductive rod configured for force transmission;
• electrical insulation that extends circumferentially over an outer surface of the electrically conductive rod and at least in sections in an axial direction along the electrically conductive rod, wherein the electrical insulation is connected mechanically to the electrically conductive rod;
• and
• an electrically conductive sleeve that is a round tube arranged circumferentially around the electrical insulation and extends at least in sections in the axial direction and along the electrical insulation,
• wherein the electrically conductive rod has at least one recess and the electrical insulation extends at least along the at least one recess, and the at least one recess is configured to limit or block at least a translational or rotational degree of freedom of the electrically conductive rod with respect to the electrically conductive sleeve, and
• wherein the electrically conductive sleeve has an embossment that extends at least in sections into the at least one recess and which is configured to mesh with a securing element of the surgical instrument, wherein the embossment is configured to block at least the rotational degree of freedom around an axis parallel to an axial direction of the sleeve when the embossment engages with the securing element, and the embossment has at least one essentially flat section configured to make essentially flat contact with a flat surface of the securing element that runs parallel to the axial direction of the sleeve and is located inwardly in a radial direction with respect to a surface of the electrically conductive sleeve.
