  • Patent number: 6409970
    Abstract: A biopsy collection system for use during colonoscopies, esophagogastroduodenoscopy, prostate and liver procedures. The system provides a device and method which enable safe and secure handling of transparent specimen containers during a biopsy collection procedure and which permit the ready visualization of minuscule tissue samples within a minimum of time during such a procedure. The device includes structure for safely securing transparent specimen containers in a hands-free condition on the device and structure for selectively illuminating one or more of the specimen containers by a light source directing light upwardly through the specimen container so that a person looking from a position above the specimen container can readily visualize the presence and quality of a minuscule tissue sample.
