Abstract
An electrosurgical apparatus for coagulating tissue includes an elongated tube having a tubular wall and a proximal end and a distal end, and constituting a conduit though which ionisable gas can be supplied to the distal end of the tube. The tube includes one or more apertures in the tube such that the ionisable gas is capable of exiting the tube in the region of the distal end of the tube. A braided tubular component is associated with the wall of the tube, and is connected to a source of electrosurgical energy, such that the braided tubular component can form part of an electrode assembly for ionising the ionisable gas exiting the one or more apertures.
Claims20
An electrosurgical system for coagulating tissue, the system including:
- a) an electrosurgical generator;
- b) a source of ionisable gas, and
- c) an instrument for coagulating tissue, the instrument comprising:
- an elongated tube having a tubular wall and a proximal end and a distal end,
- a conduit though which ionisable gas can be supplied in use to the distal end of the tube, the tube including one or more apertures in the tube such that in use the ionisable gas exits the tube in the region of the distal end of the tube,
- a braided tubular component associated with the wall of the tube, and
- a connector for connecting the braided tubular component to the electrosurgical generator, such that the braided tubular component forms part of an electrode assembly for ionising in use the ionisable gas exiting the one or more apertures.
