3.2 Use-related
The argon electrode should only be activated with suitable visual control.
Improper use of HF current can lead to burns and explosions:
•
Perform electrosurgery only with insufflation of non-flammable gases
(CO
).
2
•
Avoid direct skin contact with HF cables.
•
Avoid contact with flammable gases and liquids.
•
Burns due to deflagration during bronchial use when ventilated with
highly concentrated oxygen (100%). See study on HF surgery by the
BfArM 2009.
Improper use of the product can lead to patient injuries:
•
Avoid skin-to-skin contact between the HF cable and the patient.
•
Always grasp the connector directly when you plug in or unplug the HF
cable.
•
To prevent any personal injury that could be caused by inadvertent HF
activation, do not place the argon handle on the patient.
•
Do not use for working on metallic implants, e.g. stents, clips, etc.
The HF cable may cause interference to imagery on monitors:
•
Never route the HF cable alongside a camera cable.
•
Do not lay the HF cable in loops.
Defective or worn handles and electrodes may cause burns to the patient
and user:
Never use or repair worn or defective handles/electrodes. Dispose of them.
Hot electrode surfaces may cause patient injuries:
•
Maintain a sufficient distance between instrument tips and sensitive
tissue structures (such as pancreas or intestines).
•
Make sure not to use hot instruments for preparation.
•
The tip of the electrode may still be hot enough to cause burns
immediately after HF power has been switched off.
Never place the gas outlet nozzle of the flexible argon probes directly on the
tissue during gas activation. Danger of gas emphysema!
The gas outlet nozzle must not be guided and activated vertically above the
tissue. An angle of approx. 45ºC with respect to the tissue has been proven
to work well.
Do not inject argon into the vascular system. Danger of embolism!
Danger due to excessive intra-abdominal pressure:
•
In laparoscopic applications, argon gas flow increases intra-abdominal
pressure. The use of electronic pressure-relief controlled CO2
insufflators is recommended.
Monitor intra-abdominal pressure during activation and release pressure via
the trocar if necessary!
