1. An electrosurgical instrument comprising:
a first branch having a first metal part, the first metal part comprising:
a first sealing electrode; and
a first hinge bore;
a second branch having a second metal part, the second metal part comprising:
a second sealing electrode; and
a second hinge bore; and
a bolt arranged within the first hinge bore and second hinge bore to rotatably couple the first branch to the second branch,
wherein the first hinge bore has a first plastic jacket that coats and extends through the first hinge bore to form a bearing sleeve configured to center the bolt at an axis in the first hinge bore by compensating for production tolerances in the first metal part and is coextensive with a plastic electrode sleeve enveloping at least a distal edge of the first sealing electrode.
