Devices for selectively macerating and sculpting tissue

摘要

Various surgical fluid jet cutting instruments for selective bulk removal and precision sculpting of tissue are provided. In an exemplary embodiment, the instrument (10) includes a fluid delivery tube (12) having a nozzle (18) for forming a high pressure fluid jet (22), and an evacuation tube (14) having an evacuation port (20) or jet-receiving opening (20) opposite to and spaced apart from the nozzle (18) for receiving the high pressure fluid jet (22). In use, the fluid jet (22) and/or the evacuation port (20) can be moved relative to one another to allow the device to be selectively used for bulk removal of tissue and for precision sculpting of tissue.
