Abstract
Electrosurgical handheld devices are used mainly for endoscopic applications in urology or in gynaecology. However, the field of use of these instruments is not limited to these regions of the human body and instead also includes the treatment of further organs in the lower part of the human abdomen. The invention makes available an electrosurgical handheld device and also a handle, a main body and an adapter, which are particularly easy and cost-effective to produce and which at the same time ensure a laminar flow of the irrigation liquid at the distal end of the handheld device. This is achieved by the fact that a feedthrough extending through a handle is funnel-shaped, wherein a cross section of the feedthrough tapers from a distal side to a proximal side of the handle.
