Across
  1. 2. The quality of a substance that resists the transfer of electrons and therefore electrical current
  2. 5. A type of lasing energy that is created when electrons are removed Fromm the lasting medium
  3. 7. Sticky, semiliquid substance that forms when tissue is altered by electrical or ultrasonic energy
  4. 8. The constriction of electrical current by a nonconductive material
  5. 11. The transfer of electrical current from an active electrode to another conductive instrument by accident or as part of the electrosurgical process
  6. 15. Lasers that apply the laser light intermittently to the target tissue
  7. 19. High-frequency energy created by vibration or excitation of molecules. This type of energy destroys tissue by breaking molecular bonds.
  8. 20. The electrosurgical circuit in which current travels from the power unit through an instrument containing two opposite poles in contact with the tissue and then returns directly to the energy source
  9. 22. An acronym for light amplification stimulation emission of radiation
  10. 23. The use of cold temperatures to destroy tissue
  11. 25. The absorption of a lasing medium into tissue being lased, according to its color and density
Down
  1. 1. Electromagnetic energy in which the frequency is in the area of radio transmission.
  2. 3. In electrosurgery, the use of high voltage and relatively low frequency to cut through tissue
  3. 4. The complete destruction of tissue
  4. 6. The direct use of electricity to cut and coagulate tissue
  5. 9. In electrosurgery, the point of the electrical surgical instrument that delivers current to tissue
  6. 10. The process of tissue surface destruction used in electrosurgery
  7. 12. Inert gas used as a lasting medium during laser surgery
  8. 13. The destruction of cataracts using ultrasound technology.
  9. 14. specific burn hazard of monopolar endoscopic surgery
  10. 16. Charred tissue created by a high-voltage current
  11. 17. Inert gas used in electrosurgery to direct and shroud the electrical current
  12. 18. The toxic smoke emitted by tissue during electrosurgery and laser surgery
  13. 21. A method of tissue destruction in which a probe is inserted into a tumor or tissue mass
  14. 24. To cover or surround a conductive substance with nonconductive material
