Handling device for an electrosurgical instrument, method for producing a handling device, and electrosurgical instrument

A method for producing a handling device for an electro-surgical instrument, the handling device comprising a joint mechanism which has at least one handling-side lever configured to be moved for manipulation, a lever extension, which is configured as an electrical insulator and which is fixedly coupled to the lever, and an electrically conductive contact portion, which is fixedly coupled to the lever extension and which is arranged on a side of the lever extension that can be subjected to force via the joint mechanism and is configured for electro-surgical contacting of biological tissue, the method comprising the steps of:

• form-fittingly connecting the lever extension configured as the electrical insulator to the lever of the joint mechanism;
• fixing the form-fitting connection between the lever extension and the lever by means of a securing element;
• form-fittingly connecting an electrically conductive contact portion configured for electro-surgical contacting of biological tissue to the lever extension on a side which can be subjected to force via the joint mechanism;
• and
• fixing the form-fitting connection between the lever extension and the contact portion by means of a securing element.

An electro-surgical instrument, comprising an endoscopic instrument, having a handling device, the handling device comprising:

• a joint mechanism which has at least one handling-side lever which can be moved for manipulation;
• a lever extension, which is configured as an electrical insulator and which is fixedly coupled to the lever;
• and
• an electrically conductive contact portion, which is fixedly coupled to the lever extension and which is arranged on a side of the lever extension that can be subjected to force via the joint mechanism and is configured for electro-surgical contacting biological tissue,
• wherein the electro-surgical Electro-surgical instrument is produced by the method comprising the steps of:
• form-fittingly connecting the lever extension configured as the electrical insulator to the lever of the joint mechanism;
• fixing the form-fitting connection between the lever extension and the lever by means of a securing element;
• form-fittingly connecting an electrically conductive contact portion configured for electro-surgical contacting of biological tissue to the lever extension on a side which can be subjected to force via the joint mechanism;
• and
• fixing the form-fitting connection between the lever extension and the contact portion by means of a securing element.
