Reimagining the Gynecological Exam

Introducing the Pocket Colposcope

The new instrument with the potential to revolutionize cervical cancer screening in low-resource settings.

Cervical cancer affects the lives of 500,000 women worldwide each year, resulting in more than 270,000 deaths annually. Because the majority of cases occur in low-income countries that cannot afford the tools commonly used in the United States, new solutions must be found.

The key innovation that will help us achieve our goal is a product called the Pocket Colposcope, which was created as a result of a 3-year human centered design process between Duke , 3rd Stone Design and clinical partners in the U.S., Peru, Tanzania, Zambia and Kenya.

Unlike traditional colposcopes, the tampon-shaped Pocket Colposcope is inserted through a speculum to provide a magnified image of the cervix. Close up imaging of the cervix achieves exquisite image quality that rivals that of one of the best colposcopes on the market without the need for high-end light sources, optics or cameras.

The Pocket Colposcope is significantly less expensive, smaller and lighter than a traditional clinical colposcope.

Weighing less than two pounds, it fits inside a pocket (hence the name). The device enables healthcare providers to optically zoom in and capture acetic acid, Lugol’s iodine and vascular images (green light imaging) by pressing a button with their thumb. Images taken with the Pocket Colposcope are transmitted instantly to a smartphone, tablet or laptop.

If we can place in the hands of providers technology that is relatively low cost, that is easy to use, that doesn’t require electricity and can get to a small health center , like the Pocket colposcope and have a corresponding treatment like the thermocoagulator we can really change the story.
