Embodiment Construction

[0029] exist figure 1In , the device according to the invention is indicated generally by the reference numeral 10 . The device 10 includes a coupling unit 12 which is designed for coupling to superordinated components (not shown). The first tube 14 is connected to the coupling unit 12 , and the housing 16 is arranged at the end of the tube opposite to the coupling unit 12 . A filter 18 is accommodated in the housing 16 , which protrudes laterally from the housing 16 . In this way, the housing 16 can be designed in a weight-optimized manner. Of course, in another embodiment, the housing 16 can also be closed, ie formed around the filter. At the end of the housing 16 opposite the first tube 14 , it is connected to a second tube 20 , which is shown strongly shortened in the embodiment shown. The second tube 20 terminates at a distal end 22 .

[0030] refer to figure 2 It can be seen that the coupling unit 12 has two current line connections 24 , 26 , which extend into the...

Abstract

The invention relates to a device (10) for an electrosurgical instrument, comprising: a coupling unit (12), the coupling unit (12) having a fluid line interface and a current line interface, which are designed to conduct a fluid or a current between a superordinate component and a distal end (22) of the device (10) via a fluid line of the device (10) and at least one current line of the device (10); and a filter (18), the filter (18) being arranged separately from the coupling unit (12) in the fluid flow path of the fluid line such that the fluid flowing through the fluid line flows through the filter (18).

Description

technical field [0001] The invention relates to a device for electrosurgical instruments. Background technique [0002] Electrosurgical instruments are used in particular in endoscopy, for example for plasma coagulation. In this case, the tubular device is connected to a gas source and a high-frequency generator, and the gas is then guided to the distal end of the tubular device and converted there into a plasma by means of an electric current from the high-frequency generator. However, contamination of the tubular device can occur by backflow from the distal end of the tubular device to the gas source or radio-frequency generator. [0003] For this purpose, document WO 2004 / 002345 A1 proposes to integrate a filter into a plug of a tubular device for connection to a high-frequency generator or a gas source. However, this enlarges the corresponding plug so that its operability is seriously impaired and would also require the use of a high-frequency generator specially desig...
