Instrument shown in the photograph above is used for Endoscopic biopsy.
Endoscopic biopsies are used to reach tissue inside the body in order to gather samples from places like the bladder, colon, or lung.
During this procedure, your doctor uses a flexible thin tube called an endoscope. The endoscope has a tiny camera and a light at the end. A video monitor allows your doctor to view the images. Small surgical tools are also inserted into the endoscope. Using the video, your doctor can guide these to collect a sample.
The endoscope can be inserted through a small incision in your body, or through any opening in the body, including the mouth, nose, rectum, or urethra. Endoscopies normally take anywhere from five to 20 minutes
