Surgical instrument, tool device for such a surgical instrument, and method for producing such a tool device

A surgical instrument comprising:

• a shaft extending along a shaft longitudinal axis;
• a tool device arranged distally on the shaft and having a first jaw part and a second jaw part, the first and second jaw parts being pivotable relative to each other, about a pivot axis oriented transversely to the shaft longitudinal axis, to form an openable and closable tool mouth;
• and
• a grip device arranged proximally on the shaft and having an operating element which is operatively connected to the tool device via a push-pull element, the push-pull element being movable in translation along a longitudinal movement axis by operation of the operating element,
• the tool device having a control arrangement with a control pin and at least one control groove, the at least one control groove formed on a control portion of the first jaw part, the control pin extending parallel to the pivot axis and engaging axially through the at least one control groove, and the control pin being slidably movable by a longitudinal movement of the push-pull element, between a proximal end position of the control pin and a distal end position of the control pin along the at least one control groove to apply torque to the first jaw part that acts about the pivot axis in order to open and/or close the tool mouth,
• the second jaw part comprising a receiving recess in which the control portion of the first jaw part is received at least in part,
• at least one control projection protruding inwardly from an inner wall of the receiving recess in an axial direction of the control pin and forms a control surface of the control arrangement, and
• the control pin being slidable along the at least one control projection in a movement between the proximal and distal end positions of the control pin, the control pin being supported radially on the at least one control projection.
