Abstract
Official abstract text for this publication.
Electrosurgical forceps for efficiently severing of hollow organs, in particular vessels. The electrosurgical forceps have a first branch and a second branch for gripping the hollow organ. The forceps have at least one neutral electrode on the second branch, at least one first coagulation electrode and a second coagulation electrode that is disposed on the first branch for applying a first HF current by means of the coagulation electrode, and at least one cutting device, which is arranged between the coagulation electrodes in order to sever the hollow organ in a cutting region. The cutting device has a cutting electrode for applying a second HF current between the cutting and neutral electrodes. The coagulation electrodes are arranged spaced apart from one another in such a way that the first HF current does not flow through or only a minor amount of the same flows through the cutting region.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrosurgical forceps with a first branch and a second branch for gripping a hollow organ, comprising: at least one first neutral electrode and a second neutral electrode on the second branch, the first and second neutral electrodes being characterized in that the first and the second neutral electrodes respectively span a plane and are arranged such that the planes intersect at an acute angle; at least one first coagulation electrode and a seco…
