Abstract
A waterjet surgery system comprising a water pump, a fluid line (4) and a nozzle, wherein the fluid line (4) connects the water pump to the nozzle, wherein the nozzle is embodied within a position stabilizing body (8), and a method for shaping such a position stabilizing body (8) comprising the steps of: • imaging hard tissue (16), particularly bones (10), of a patient on which surgery is to be carried out; and • forming a nozzle within a position stabilizing body (8) by rapid prototyping, wherein the position stabilizing body (8) is shaped to match the shape of the bones (10) of the patient at a position which has to be subjected to surgery. The position stabilizing body (8) is shaped to match the shape of an external object (10) on which it is to be applied. The position stabilizing body (8) can be provided with fixation means to assist in fixing the position of the body (8) in relation to an external object (10). The fixation means can comprise inflation means mounted on the position stabilizing body (8). The inflation means can comprise an inflatable cushion. The fixation means can further comprise a friction coating provided on the position stabilizing body (8) and/or on inflation means provided on the position stabilizing body (8).
