  1. AMTELECTROSURGERY INTEGRATING SAFETY AND PERFORMANCE BASICS OF ELECTROSURGERY

  2. Basics of Electricity

  3. Electrosurgial Principles • Current follows pathway of least resistance • Current always seeks to complete the circuit • As Resistance within the circuit increases, current flow decreases

  4. Neromuscular Stimulation

  5. Tissue Effects: • Cutting • Desiccation • Fulguration • Soft Coagulation • Bipolar • Argon Plasma Coagulation

  6. Cutting • Continuous high-frequency current • Cause quick, clean cutting • Minimal Thermal Artifact • Blended Current • Combination of cutting and coagulation waveform characteristics • Moderate hemostasis

  7. Desiccation (Forced Coag) • Contact Coagulation • Slow drying out of tissue • Varying degrees of thermal artifact • Causes eschar to form

  8. Fulguration (Spray Coag) • Non contact • High Voltage • Electrical current arcs from electrode to tissue • Superficial

  9. Soft Coagulation • Contact Coagulation • Low Voltage • Continuous waveform • Non Sticking non charring • Reproducible

  10. Bipolar • Contact coagulation • Low voltage • Safer than monopolar • Non charring

  11. Argon Plasma Coagulation • Non contact • Non Charring • Superficial

  12. Argon Plasma Coagulation

  13. Argon Plasma Coagulation

  14. ESU’s • Conventional • Constant Voltage • Hyfrecator • Argon Plasma Coagulation

  15. Return Electrodes • Non CQMS • CQMS • Capacitive Pads

  16. CQMS Technology

  17. Capacitive Pad

  18. Active Electrodes: • Monopolar • Pencils • Laparoscopic • Forceps • Bipolar • Laparoscopic • Forceps

  19. Troubleshooting • Operator Errors • System Errors • Accessory Failures

  20. Buzzing a Hemostat • Good Practice? • How to do it safely

  21. Surgical Staff Burns • How do they occur? • How to avoid them
