Endoscopic devices are specialized instruments used in medical procedures to visualize and access the interior of the body. They consist of a long, flexible tube equipped with a light and camera, allowing doctors to examine organs and tissues without making large incisions. Commonly used in procedures like gastroscopy and colonoscopy, these devices help diagnose conditions and guide treatments. These devices can also be fitted with various tools, such as biopsy forceps or laser systems, to perform interventions during the examination. This minimally invasive approach reduces recovery time and minimizes patient discomfort, making it a preferred option for many diagnostic and therapeutic procedures.
