Mode of operation
In bipolar HF surgery, tissue coagulation is achieved by applying a high-
frequency AC current, which generates heat.
The ERGO 315R vessel sealing instruments are invasive surgical
instruments for use in laparoscopic or open surgery.
They are used through surgically produced access openings in conjunction
with devices for endoscopic use, such as trocars and optics.
The active electrodes are the non-insulated areas of the jaws. The HF
current flows from one electrode of the instrument through the biological
tissue to the other electrode to produce the desired localised tissue effect.
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 haemostatically tight with respect to systolic blood
pressure and permanently closed.
The instrument can be used for vessels with diameters up to 7 mm.
The integrated cutting function of the ERGO 315R allows the tissue to be
cut under treatment immediately after sealing without first changing
instruments.
The electrodes can be opened, closed and latched by actuating the handle.
A ratchet mechanism in the handle generates a reproducible mechanical
pressure on the electrode tips when the handle is closed. The jaw can be
rotated and positioned by a rotation wheel on the handle.
