A biopsy device for obtaining tissue specimens, particularly from endocervical canal. A cutting anvil, typically of a non-metallic material such as plastic, is carried at one end of an elongated shaft. An annular cutting blade, typically of a metallic material, on the end of a hollow shaft is telescoped on the shaft carrying the cutting anvil. The device includes a locking arrangement to lock the cutting edge of the device in engagement with the anvil during insertion of the device to the selected site and during removal of same from the body so that during insertion there is no inadvertent damage to tissue and, most importantly, no inadvertent loss and spreading of possibly diseased tissue and cells during removal. Further, the device includes an adjustment means whereby the size of the specimen may be selected prior to insertion in the patient.

Biopsy device

Apparatus for testing a surface coating on a glass container. In this apparatus, a glass container is chucked in place on a movable carriage. A second glass container is held in a fixed position above and touching the first glass container. A load of a pre-determined magnitude is then applied normal to the second glass container, the load thereby being transmitted to the first glass container. The carriage is moved to cause the two glass containers to translate relative to one another. The force required to move the carriage is transmitted through a load cell which gives an output signal indicative of the force. The surface coatings applied to the glass containers should withstand a normal load of about one hundred pounds before breaking down and allowing the glass containers to scratch one another. If a scratch occurs during the test, the force required to move the carriage will increase and this may be easily seen.
