You can activate the CUT and COAG function of the monopolar receptacle with the two pedal footswitch. CUT/COAG window of the monopolar receptacle

Activation with fingerswitch Do I have to make any settings on the VIO? No. If you have connected, for example, an instrument to the monopolar receptacle, you can also activate the CUT and COAG modes with the fingerswitch. Activation with AUTO START The program stores whether the bipolar COAG modes are activated with AUTO START.

Is the patient protected by the return electrode? The return electrode receptacle is equipped with pilot lamps which represent a dual-surface (1) and a single-surface (2) electrode. GO

Observe the pilot lamps.

Unit can be activated Return electrode receptacle from the receptacle connector of the VIO system

The return electrode (1) or (2) lights up GREEN. Alarm! The return electrode (1) or (2) lights up RED. When the VIO is activated a warning signal sounds. In the event of an alarm check:

•

Is a return electrode connected?

•

Is the connector of the return electrode inserted in the return electrode receptacle of the VIO?

•

Is the return electrode cable undamaged?

•

Is the contact tab of the return electrode completely inserted into the connecting clamp?

•

Is the return electrode positioned with its entire surface on the patient’s skin?1

•

Does the symmetry line of the return electrode point towards the operating field?1

When is there a risk of explosion?

The most important safety measures

GO When using anesthetics and disinfectants make sure that they are not combustible. As a minimum requirement, such substances must have completely evaporated and been removed from the spark formation zone before use of the electrosurgical unit..

Who may prepare and operate a VIO system? Electrosurgery is associated with various risks to patients and personnel. The VIO system should therefore only be operated by persons who have received training.

Endogenous gases in the gastrointestinal tract also present a risk of explosion.

How should I position the patient?

How do I handle the active electrode (instrument)?

GO

The covering of the operating table does not insulate the patient from the metal parts of the operating table. Between the patient and the operating table cover insert a layer of electrically insulating material, e.g. dry cover cloths. If there is the risk of the material becoming wet during the operation (blood, sweat, irrigation liquid, urine), also place a waterproof layer on top of this material. Separate off points of contact between extremities/folds of skin and the trunk using dry cloths.

GO Always put the electrode down in a safe place. Never next to or on the patient. Risk of accidental activation.

If the electrode is accidentally activated during an endoscopic application, switch off the power switch of the electrosurgical unit. Only then should the electrode be removed from the patient’s body. Electrodes are hot after activation. They can also burn tissue without being activated.

How should I apply the return electrode?

With an active monopolar electrode do not touch metal instruments held in the other hand. Danger of burns!

GO

Apply the entire contact surface of the return electrode carefully to a muscular part of the body with good blood circulation. It should be as close as possible to the operating field. Align the symmetry line of the return electrode towards the operating field. The current should flow from the active electrode (instrument) to the symmetry line of the return electrode. How should I proceed for patients with cardiac pacemakers? GO In the case of patients with cardiac pacemakers or other active implants, there is a risk of malfunctioning or damage to the pacemaker. In the case of doubt expert advice should be obtained.
