The Olympus UM-BS20-26R is a medical endoscopic ultrasound (EBUS) miniature probe made by Olympus.
It is a radial scanning ultrasound probe designed to be used with a bronchoscope (lung endoscopy). Doctors insert it through the working channel of the scope to image inside the airways.
What it does
It provides:
360° radial ultrasound imaging
20 MHz high-resolution images
Visualization of bronchial wall layers and nearby structures
This helps doctors distinguish:
Tumors growing into the airway (infiltrating lesions)
Tumors pushing from outside (compressing lesions)
Key features
Type: Radial mechanical endobronchial ultrasound probe
Frequency: 20 MHz
Diameter: fits 2.8 mm bronchoscope working channel
Imaging: full 360° cross-sectional view
Balloon sheath (MAJ-643R): used for acoustic coupling (improves image quality inside airways)
Use area: pulmonology / thoracic surgery
Simple explanation
The UM-BS20-26R is basically:
a very thin ultrasound probe used during lung bronchoscopy to see the structure of airway walls and nearby tissue in high detail.
