Diseased tissue is liquefied in the presence of non-diseased tissue by contact with a paddle moving with angular velocity. The edge of the paddle is dull and the angular velocity is sufficient to batter the diseased tissue into a liquid without adversely affecting the structure and function of the non-diseased tissue. The shape of the paddle and the rotational speed can be designed and chosen depending on the consistency of the tissue to be resected, whether hard or soft. Upon liquefaction, the diseased tissue is removed by vacuum aspiration. This instrument therefore gives the neurosurgeon the ability to differentially resect diseased tissue while preserving the surrounding structures intact. The process is carried out using an inexpensive, maneuverable, small caliber instrument in a highly efficient manner |
