Electrosurgery: Procedure and Tools
One of the most common procedures in the operating room is electrosurgery. Electrosurgery tools are now widely used in various operations like minor surgeries in outpatient departments.
What is Electrosurgery
Electrosurgery is used to destroy benign and malignant lesions, control bleeding and excise tissue at a particular location. It works by passing electrical current through the tissue to attain the desired result. It has many applications, like the removal of warts or other superficial lesions without suturing.
The procedure cuts or controls bleeding by inducing coagulation or hemostasis. It happens because the device delivers high-frequency electrical current and voltage through an active electrode. This essentially vaporises the tissue on the surgical site.
The procedure can be performed using either monopolar or bipolar instruments. The difference between these instruments are the pathways of the current used. One of the most commonly used tools is the nonstick bipolar forceps, which provides high thermal diffusivity to prevent sticking and charring of tissue.
Despite its long-time use in the medical field, it is still imperative that the surgical team are knowledgeable of the principles involved in the procedure. Understanding the science behind electricity and electrosurgery is critical to properly eliminate hazards they could possibly encounter during surgery.
