Interchangeable tissue macerating and sculpting devices.

摘要

Various surgical fluid jet cutting instruments for selective bulk removal and precision sculpting of tissue are provided. In one exemplary embodiment, the instrument (10) can include a fluid delivery tube (12) having a nozzle (18) for forming a high pressure fluid jet (22), and at least two evacuation tubes (16) that are adapted to be selectively and removably coupled to the fluid delivery tube. Each evacuation tube can have an evacuation port (16a) or jet-receiving opening that is adapted to be positioned opposite to and spaced apart from the nozzle for receiving the high pressure fluid jet. Each evacuation tube can also be adapted for a specific use. For example, the instrument can include a first evacuation tube that is adapted to allow bulk removal of tissue, and a second evacuation tube that is adapted to allow precision sculpting of tissue.
