Biopsy Instruments
A number of biopsy instruments are in use. The Novak curette is a thin metallic tube with a side opening at the tip; suction with attached syringe can be applied to help to remove tissue. The Pipelle is a more flexible plastic tube with a side opening at the tip. A smaller tube (internal piston) inside the Pipelle will be withdrawn to create suction. The pipelle will be rotated and moved in and out to collect small pieces of endometrial tissue. Recently, the TruTest has been introduced as an alternative method of endometrial biopsy. Rather than using a suction tube, this method uses the Tao Brush to gently brush the lining of the uterus. Generally, this method has been found to be less painful than the traditional suction method.

Famous quotes containing the word instruments:
“Water, earth, air, fire, and the other parts of this structure of mine are no more instruments of your life than instruments of your death. Why do you fear your last day? It contributes no more to your death than each of the others. The last step does not cause the fatigue, but reveals it. All days travel toward death, the last one reaches it.”
—Michel de Montaigne (1533–1592)
