Electrosurgical handheld device and also a proximal, central and distal portion of a main body of an electrosurgical handheld device

A main body for an electrosurgical handheld device, comprising a handle that is configured to connect at a distal side of the handle to a distal portion of the main body and at a proximal side of the handle to a proximal adapter of the main body, wherein:

• the handle has an axial bore for passage of a shaft-like component of the handheld device, and parallel to the axial bore, the handle has at least one feedthrough for passage of an electrode arm of an electrode instrument of the handheld device,
• the electrode instrument includes at least one electrode arm,
• the feedthrough is funnel-shaped,
• cross-sections of the feedthrough gradually taper from the distal side to the proximal side of the handle, such that a first cross-section of the feedthrough at the distal side is oval, and a second cross-section of the feedthrough at the proximal side is circular;
• the electrode arm of the electrode instrument has an offset that is configured as a step-like transition between a proximal and a distal region of the electrode arm, and the proximal and the distal region of the electrode arm are oriented parallel to each other;
• and
• the offset of the electrode arm of the electrode instrument being provided within the first cross-section that is oval.
