Abstract
A waterjet surgery system (1) comprising a water pump (3), a fluid line (4) and a nozzle (5), wherein the fluid line (4) connects the water pump (3) to the nozzle (5), wherein the nozzle (5) 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 (15) 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 (15) at a position which has to be subjected to sur— gery. The position stabilizing body (8) is provided with fixation means (9) to fix the position of the body (8) in re— lation to an external object (10). The fixation means can be embodied with pins. Alternatively the fixation means (9) can comprise inflation means (11) mounted on the position stabi— lizing body (8). The inflation means (ll) can comprise an in— flatable cushion (12). The fixation means (9) can further comprise a friction coating (13) provided on the position stabi— lizing body (8) and/or on inflation means (11) provided on the position stabilizing body (8). It is also possible that the position stabilizing body (8) is shaped to match the shape of an external object (10) on which it is to be applied.
