Improved thermofusion and dissection

The EnSeal PTC combined with the intelligent regulation of the ERBE VIO electrosurgical system offers a distinctly improved vessel-sealing quality. Astudy conducted in the US shows it is possible to thermofuse vessels with diameters of up to 7 mm to create a seal capable of withstanding burst pressures of up to 900 mmHG. Figures of this magnitude, which are an indication of the safety of thermofusion to treat vessels, have not been achieved by any other comparable procedure to date, it is stated.

The electrical resistance of the PTC electrodes embedded in the thermo-synthetic material of the jaw of the EnSeal changes depending on the temperature, thereby regulating the flow of current and the development of heat in the tissue. PTC is positive temperature control.

This temperature regulation has the advantage that it reduces lateral damage (thermal spread) to a minimum and spares adjacent structures. Irrespective of the individual properties of the tissue, the grasped tissue is homogeneously thermofused with the help of PTC – without carbonisation and with only minimal smoke plume. The operating surgeon has good visibility at the operative site and can carry out coagulations, preparations and dissections quickly and safely with a single instrument.

In addition to the thermoenergy advantages, the clamping/cutting function integrated in the jaw also contributes to the effective sealing of vessels and tissue. During the subsequent dissection, injuries to adjacent structures are excluded.

The embedded cutting mechanism (I-blade) severs the fusion seam exactly down the middle, leaving a homogeneous, identically fused margin on either side and thus creating a good safety margin.
