Abstract
Tissue separator structure and method which in its simplest form comprises a mechanical nudger on the end of a stem for mechanically separating tissue and in the preferred embodiment includes a fluid medium passing through the stem and out of a floating tip to separate the tissue with the directed, controlled pressure of the fluid medium and/or nudging by the floating tip. In a more sophisticated embodiment of the invention, plural fluid medium forces are provided on the tissue to be separated to perform separating and clearing operations and in further embodiments, the area of the tissue being separated may be moistened and/or fluid and debris removed from the area of tissue separation. The stem may be disposable in accordance with the invention. Further in accordance with the method of the invention, tissue is separated by mechanical nudging and/or by means of a fluid medium under pressure. The method may include the steps of moistening the tissue to be separated or withdrawing fluid and debris from the area of the tissue to be separated. In one modification of the method of the invention, the structure of the invention may be used to clean the teeth with fluid pressure from a wa…
