METHOD AND DEVICE FOR TISSUE VAPORIZATION AND EXTRACTION

摘要

The present invention provides methods and devices for extracting tissue from internal surgical sites. The method comprises removing tissue from the uterus by applying radio frequency electrical power to the tissue so that a portion of the removed tissue is vaporized. While removing the tissue, the depth of tissue removed is viewed and the removed tissue is evacuated from the uterus. The radio frequency power is applied by an electrosurgical member (202) of a probe (200), the probe also having an imaging mechanism (222) and an aspiration lumen (218). In some embodiments, the removed tissue is either fragmented or morcellated within the uterus to avoid clogging of the aspiration lumen (218). In other embodiments, substantially the entire removed tissue is vaporized.
