Energy Sources in Surgery

3. an inert gas used in electrosurgery to direct and shroud the electrical current
4. to cover or surround a conductive substance with nonconductive material
8. energy that destroys tissue by breaking molecular bonds
9. energy in which the frequency is in the area of radio transmission
14. an inert gas used as a lasing medium during laser surgery
15. the combination of the concentration of laser energy and the length of time tissue is exposed to it
17. the direct use of electricity to cut and coagulate tissue
19. the destruction of cataracts using ultrasound technology
21. the quality of a substance that resists the transfer of electrons and therefore electrical current
22. toxic smoke emitted by tissue during electrosurgery and laser surgery
24. the use of high voltage and relatively low frequency to cut through tissue

1. the component of the laser system that holds the lasing medium
2. a sticky, semiliquid substance that forms when tissue is altered by electrical or ultrasonic energy
4. the constriction of electrical current by a nonconductive material
5. charred tissue created by a high voltage current
6. a process of tissue surface destruction used in electrosurgery
7. the use of extremely low temperature to destroy diseased tissue
10. the point of the electrosurgical instrument that delivers current to tissue
11. a type of lasing energy that is created when electrons are removed from the lasing medium
12. a conductive pad that captures electricity and shunts it safely out of the body and back to the electrosurgical unit
13. an instrument that destroys tissue through the use of high frequency sound waves
16. the complete destruction of tissue
18. the power generator and control source in the electrosurgical system
20. an electronic device that monitors and corrects physiological conditions
23. acronym for light amplification by stimulated emission of radiation
