Abstract:
The coagulation arrangement (10) according to the invention comprises an instrument (11) having a tool (17) comprising coagulating electrodes (22, 23, 27, 28), as well as a dissecting electrode (36). The electrodes are powered by a circuit (44) that comprises a coagulating voltage source (54) and a dissecting voltage source (55), or that can be connected to such sources. The device comprises a dissection actuating switch (60) and a coagulation actuating switch (59). The former is connected to a power switch (58) that—in dissecting mode—connects the current path from the dissecting voltage source (55) to the dissecting electrode (36), before the dissecting voltage source (55) or the HF output voltage source (47) and the coagulating voltage source (54) are actuated. Thus, the user is presented with a reliable means in a simple manner in order to be able to more flexibly perform more complex operations.
