Embodiment Construction

[0018] As shown in Figure 1, the instrument 30 1 to 30 n It contains a hollow body with a distally arranged nozzle 32 , in which an electrode 31 is arranged adjacent to the nozzle. used to enable the switch S 1 to S n An activated activation switch 33 is provided as activation element. Electrode 31, switch S 1 to S n and instruments 30 1 to 30 n is connected to the instrument hub 12 on the APC device through the connection line 34 and the instrument connector 35. From here the line is routed to the HF generator 10, to the argon source 16 via the valve 15, and to the control device 11 which (open loop or closed loop) controls the generator 10 and possibly also the argon source (in particular is its pressure).

[0019] The above description is only a description of principle and does not show the exact structure of known APC devices. In particular, device 30 1 to 30 n It can be constructed differently, for example as a detector, wherein the activation switch 33 is us...

Abstract

The invention relates to an APC device for operating a device for argon plasma coagulation. The device comprises: an HF generator for generating a coagulation current; a control device for controlling the HF voltage amplitude to adjust a high firing voltage in response to an excitation signal, and to automatically adjust a low operating voltage. An outlet hub is also provided for connecting instruments. The object of the present invention is to enable multiple instruments to work simultaneously. Then, not just one but a plurality of instrument hubs are used to connect additional instruments, and the control device is connected to all instrument hubs and is configured such that when at least one excitation element is activated and generates at least one excitation signal, all The RF voltage is interrupted for a defined interruption duration. The HF voltage is then adjusted to the ignition voltage and, after the plasma on all connected APC instruments has ignited, the HF voltage is adjusted to the operating voltage.

Description

technical field [0001] The invention relates to an APC device. Background technique [0002] APC devices have been disclosed for operating instruments for argon plasma coagulation, in which other inert gases can also be used in addition to argon. Reference is made here to WO 93 / 01758 by way of example only. [0003] In large-scale operations, ie when multiple surgeons are treating a patient at the same time, a separate APC must be available to each surgeon so that he can connect the instruments he is using. And this is often not possible, not only for reasons of cost, but also because it would result in a highly crowded space environment. Contents of the invention [0004] The object underlying the invention is to construct an APC device that enables simultaneous operation of several instruments with a single device. [0005] In the case of an APC device for operating at least one apparatus for argon plasma coagulation, the device comprises: an HF generator for generati...
