A thoracoscope is a medical instrument used for examining the chest cavity. It is a type of endoscope specifically designed to visualize the lungs and surrounding structures. The procedure, known as thoracoscopy, allows doctors to diagnose and treat various conditions, such as infections, tumors, or pleural effusions, by inserting the thoracoscope through small incisions in the chest wall. This tool is equipped with a light and camera, providing real-time images to the physician. The use of a thoracoscope is less invasive than traditional open surgery, leading to shorter recovery times and reduced pain for patients. It is commonly used in conjunction with other procedures, such as biopsy or drainage.
