What is a biopsy?

A biopsy is the removal of a small sample of tissue from a suspected part of the body for examination and making a definitive diagnosis. For example, a biopsy may be performed to determine if the abnormal tissue is benign, malignant, or infected. Biopsies can be as small as a millimeter (1/25th of an inch).


How is a biopsy performed?

Biopsies are usually taken with a needle through a small incision. To compensate for the lack of direct visual accessibility, surgeons use computed tomography (CT) and X-ray images (fluoroscopy) to guide the biopsy.  Finding the right spot for the biopsy can be difficult, especially with very small lesions. This can increase operation time, and may cause more tissue damage and a larger scar.


Biopsy-MazorWhat are the advantages of biopsies performed with the Mazor Robotics Renaissance® Guidance System?

Renaissance® allows surgeons to create a preoperative surgical blueprint, which acts as a map for pinpointing the exact location to take a patient’s biopsy. During the procedure, Renaissance® guides the surgeon according to their patient’s surgical blueprint, which can increase accuracy while possibly reducing the amount of fluoroscopy used.1
