Area of Science:

Physics
Biomedical Engineering
Surgical Technology

Background:

Einstein theorized stimulated emission for unique electromagnetic radiation in 1917.
Laser (light amplification by stimulated emission of radiation) light is high-intensity, parallel electromagnetic radiation.
Wavelength determines laser application; CO2 lasers are used in various surgical specialties.

Purpose of the Study:

To describe the principles and applications of laser technology in surgery.
To highlight the efficacy and safety of carbon dioxide (CO2) lasers in surgical procedures.
To emphasize the necessity of specialized training for laser surgery.

Main Methods:

Utilizing the thermal vaporization action of the CO2 laser beam.
Directing the CO2 laser through an operating microscope or hand-held component.

Related Experiment Videos

Focusing the laser beam to a focal spot with minimal damage to adjacent tissues.

Main Results:

The carbon dioxide laser is successfully employed in gynecology, otorhinolaryngology, neurosurgery, plastic, and general surgery.
CO2 laser surgery demonstrates thermal vaporization as its basic action in tissue.
Minimal damage to adjacent tissues is observed with CO2 laser use.

Conclusions:

The CO2 laser is a valuable tool in modern surgery due to its precision and minimal collateral damage.
Specialized training in laser surgery techniques and safety standards is crucial for surgeons.
Laser technology, particularly the CO2 laser, offers advanced therapeutic options across multiple surgical disciplines.
