Smoke Evacuation Attachment for Electrocautery Pens

Electrosurgery is one of the most common surgical techniques utilized in the field of otorhinolaryngology (ENT), that allows clinicians to both cut tissue and coagulate blood vessels. Within ENT, electrosurgery is commonly conducted using electrocautery pens, which are handheld devices used by clinicians in both invasive and minimally invasive procedures. Examples of the procedures include tonsillectomies and nasal mass removals. These pens pose a significant risk to users due to the smoke byproduct of the burning tissue, and their current designs inadequately remove the smoke from the surgical area. In addition, many of the current suction component designs are bulky, and can make operating in smaller areas difficult for the user. We have created an attachment for electrocautery pens that does not hinder the surgeon's procedure while effectively evacuating 90% of the smoke produced.
