Direction for use of Thoracoscopic HF Electrodes and instruments



              adaptor and joints must be treated  with an   When using electrical cardiograms (ECG)
              appropriate paraffin oil based preservative.  the following points must be observed.
                                                •  Connect neutral ECG cable to the neutral
              Warning! The rotation adapter and sliding   HF electrode.
              surface of the piston must be greased with
              our special care lubricant. (Art. No. 26905-  •  The distance between active HF electrode
                                                and ECG electrodes must be at least 150
              00)
                                                mm.
                                                •  Do not use ECG needle electrodes.
              5.0 Assembly and                  •  All ECG electrodes must have HF choke
              inspection                        or protective circuitry.
                                                Cardiac Pacemaker:
              The valve is to be put back together and test-
              ed in the same way as described in 3.2.  •  Cardiac pacemakers could be damaged
                                                by HF power.
              6.0 Maintenance                   •  Before using please consult a
                                                cardiologist.
                                                •  Never make ambulant operations on
              Should any  serious damage to the coating   patients with cardiac pacemakers.
              appear on any part of the valve please send
              the valve to us for repair.

              7.0 Hints for avoiding of
              mistakes
              •  Be sure that the power paths between
              neutral electrode and MICTEC HF
              instruments are as short as possible.
              •  The power path must not cross through
              the body and absolutely never across the
              thorax.
              •  The HF cable and the HF instrument must
              not be allowed to lay directly on the patient’s
              skin, as this could lead to burns caused by
              capacitive currents.
              •  The HF cable must not be allowed to
              coil or lay in a coil as this could result in
              dangerous inductive currents.
              •  Completely insulate the patient from any
              contact with any other conductive surfaces.
              •  Ground the operation table!
              •  Avoid skin-to-skin contacts on arms and
              legs of the patient, for example by wrapping
              in dry gauze.
              •  Switch on HF power only when the HF
              instrument is in contact with the tissue that is
              to be coagulated.
              •  The tissue to be coagulated must not
              be in touch with any part of other tissue
              surfaces, since it could lead to unwanted
              coagulations.
              •  Cord or band shaped tissue parts may be
              coagulated only at the thinnest part.
              •  The coagulating HF instrument tip must
              be at least 10 mm from other surgical
              instruments.
              •  When using gas, for example insufflation
              gas, make sure that only non-inflammable
              gas is used, otherwise explosions and
              oxygen burns could result.
              •  The size of the neutral electrode must be
              appropriate for the power of the HF used, as
              it could lead to burns on the wrong place.
