ABSTRACT:
A hand-held surgical apparatus with supporting equipment comprising a mechanism for producing a pressurized jet of fluid which is sufficiently energetic to fragment diseased human and animal tissue without damaging adjacent healthy tissue. Preferably the apparatus includes a jet of fluid which impinges obliquely onto the operative area such that diseased tissue underneath overlying healthy tissue may be fragmented, especially finger-like extensions from tumorous growths of the skin. The jet rotated about a generally vertical axis such that the points of impact of the water from the jet upon the operative area describes circular patterns, thereby effectively and quickly distributing fragmenting energy over a wide operative area. A supporting vacuuming apparatus for aspirating effluent or expended fluid and fragmented tissue from the operative site. A surgical procedure for removing tumorous growths at the cutaneous surface includes the steps of impinging a growth on the skin with a jet of pressurized fluid using the apparatus.
