Jejoong-Cove
|
|
The Cove machine is a high frequency electrosurgical unit.
Adoption of a high-frequency bandwidth of 5MHz has the following advantages:
> Generating sine waves as output waveform to minimize the formation of scars due
to arcs during operation.
> Minimizing thermal damage to surrounding tissues through focus- ability, a property
of high frequency, producing an effect of concentrating energy onto one spot.
> Utilizing soft plasma technology
> Useful coagulation for wide bleeding range
> 5 steps Output power control
> Equipotential: An electronic current generated from the difference between ones
concentrated on the return pad and ground may cause burns. Therefore, the technique
of giving the return pad a proper ground connection was adopted to remove differences
of the electronic current.
> Carrier wave: prevents carbonation resulting from arcs, attachment of tissues
onto the surface of the electrode and the occurrence of secondary bleeding.
Unlike earlier surgical devices, COVE has the advantage of a coagulation effect
as follows:
> There is no carbonation of tissues when they are coagulated.
> The electrode does not generate heat so tissues do not stick to it even though
a special electrode is not used.
> Transmission of a minimum level of thermal energy at the time of tissue coagulation
minimizes damage to tissues.
