Embodiment Construction

[0025] In the following description, the same reference numerals are used for identical and identically acting components.

[0026] as from figure 1 and 2 As is known from , the neutral electrode comprises two usually metallic electrodes 11 , 12 which are placed on a carrier 15 and firmly connected thereto. The active surfaces of the electrodes 11, 12 that are not connected to the carrier or are not covered by the carrier, in figure 2 In the electrode state shown in , that is to say before its use, it is covered by a cover film 16 . as in figure 2 As indicated in , the cover film 16 can be made of a homogeneous material, which film has a defined electrical resistance. However, it is also possible to use individual contacts and resistors between them (which in turn can be designed as foils), so that a so-called defined resistor is formed between electrodes 11 and 12 .

[0027] Connecting lines 13 , 14 are provided for connection to an electrosurgical device, which are el...

Abstract

A coded neutral electrode including at least two electrodes electrically insulated from each other and having active surfaces for application to a skin segment of a patient, and a cover film, having a known electrical resistance, removably attached to the active surfaces in such a way that the active surfaces are electrically connected to each other by means of the cover film, and an electrosurgical apparatus for use with the coded neutral electrode and methods of production and use of the coded neutral electrode.

Description

technical field [0001] The invention relates to a neutral electrode according to the preamble of claim 1 and an electrosurgical device according to the preamble of claim 4 and also to a plastic material according to claim 7 Use of a thin film or ceramic thin film and a method for producing and operating a neutral electrode according to claim 8 . Background technique [0002] In electrosurgical devices it is known to connect different instruments to one or the same device. In order to adapt the electrosurgical device to the connected instrument, it is known, for example, from DE 4339049C2 to implement a code, for example, to inform the device of the code through the existing resistance in the instrument and the interface of the instrument on the electrosurgical device, so that it can be obtained from Read the data of the connected instruments in the comparison list and adjust the electrosurgical device accordingly. [0003] In many cases, monopolar instruments are used in e...
