Energized dissection tools
أبريل 2023
Introduction
Energized dissection tools are commonly used to cut, coagulate, and dissect tissues during various surgical procedures.
These tools utilize electrical energy to achieve precise tissue dissection and hemostasis.
There are several types of energized dissection tools, each with its own mechanism of action and specific applications.
Electrosurgical Units (ESUs):
Mechanism of Action
ESUs work by delivering high-frequency electrical currents to tissues. The electrical current passes through the tissue, resulting in tissue heating, vaporization, and coagulation.
How to Use ?
ESUs consist of a generator, a handpiece, and various electrodes.
Surgeons can select different modes (cutting, coagulation, or blend) and adjust power settings as per the requirement of the surgical procedure.
Ultrasonic Dissection Devices:
Mechanism of Action
Ultrasonic devices use high-frequency sound waves to mechanically fragment tissues. The device's tip vibrates at an ultrasonic frequency, causing cellular disruption and tissue fragmentation.
How to Use ?
Surgeons hold the ultrasonic device against the tissue, and the vibrating tip is moved along the tissue plane to dissect or fragment the tissue
Harmonic Scalpel
Mechanism of Action
The harmonic scalpel combines mechanical vibration and ultrasonic energy to cut and coagulate tissues.
It uses ultrasonic vibrations to simultaneously cut and coagulate tissues, minimizing bleeding.
How to use ?
Surgeons use the harmonic scalpel similar to a conventional scalpel, applying it directly to the tissue.
The device's energy activates upon contact with the tissue, allowing for precise cutting and hemostasis.
Laser Devices:
Mechanism of action
Surgical lasers deliver concentrated light energy to tissues, causing precise cutting and coagulation.
Different types of lasers, such as CO2, Nd:YAG, and diode lasers, are used in surgical practice.
How to use?
Surgeons focus the laser beam on the tissue, and the energy is absorbed, resulting in tissue vaporization or coagulation.
Steralization
Common sterilization methods include autoclaving, ethylene oxide gas sterilization, or low-temperature hydrogen peroxide plasma sterilization.
It is essential to follow the manufacturer's instructions and guidelines for proper sterilization and maintenance of each type of energized dissection tool to ensure patient safety and equipment longevity.
