3. Functionality
In bipolar HF surgery, tissue coagulation is achieved by
applying a high-frequency AC current, which generates heat.
The TissueSeal and TissueSeal PLUS ligation instruments
are invasive surgical instruments for use in laproscopic or
open surgery.
The active electrodes (electrode surfaces) are the non-
insulated areas of the jaws.
The HF current flows from one electrode surface of the
instrument through the biological tissue to the other electrode
surface and produces the desired coagulation in a localized
region.
With this method, sealing of a vessel or tissue segment
carrying blood is achieved by HF current in combination with
supplementary pressure.
The sealed location is hemostatically tight with respect to
systolic blood pressure and permanently closed.
Applies only to vessels up to 7 mm in diameter.
The jaws can be opened and closed by actuating the handle.
A ratchet mechanism in the handle provides reproducible
mechanical pressure on the electrode tips when the handle
is closed.
