Definitions

  • the invention relates to a method for the surface treatment of an implant, the implant being intended and suitable for medical purposes to be introduced into a living body and to remain there.
  • a liquid usually water
  • very high pressure which can amount to a few thousand bar
  • a high-pressure water jet is formed.
  • the pressure is converted into the pulse of the high-pressure water jet so that the high-pressure water jet can also be used to cut very hard workpieces, such as those made of steel or ceramics. If the water jet is less intense, the surface of a body can also be processed with it, for example to clean the surface or to deburr components.
  • a method for water jet machining of the surface of a workpiece is known from EP 2 145 689 A1.
  • a high-pressure water jet is used, which is modulated with the help of an ultrasonic transducer. This modulation divides the water jet into sections with a higher or lower speed, i.e. with a higher or lower impulse, but there is no interruption of the water jet.
  • the method according to the invention for the surface treatment of an implant has the advantage that a uniform roughening and preparation of the implant can be achieved and optimal growth in the living tissue, in particular in the bone tissue, is made possible.
  • the upper surface of the implant is treated as follows for the use of a water jet cutting device.
  • the implant has a smooth upper surface, at least in the areas that are to come into contact with the living tissue.
  • the surface is then processed with a high pressure water jet in such a way that the initially smooth surface is roughened.
  • the water jet cutting device comprises a nozzle through which the high pressure water jet is ejected, the nozzle having a movable valve element which periodically interrupts the high pressure water jet so that the high pressure water jet hits the surface in individual jet pulses.
  • the processing of the surface of the implant with the help of a high pressure water jet has the advantage that the surface is free of substances that prevent the implant from growing in the living body.
  • the high-pressure water jet which is generated with pure water, does not introduce any foreign substances, in particular no particles or chemical substances.
  • the use of the pulsed water jet allows precise machining of the surface of the implant at a short distance, as individual jet pulses, i.e. individual groups of droplets, hit the surface and remove material from the surface in a precisely controlled manner. Because of the small machining distance, the surface can be machined very precisely.
  • purified, sterile water is used for the high-pressure water jet. This water prevents contamination of the surface or the introduction of particles into the surface, so that the processing of the implant does not experience any disadvantages with regard to its compatibility in medical applications.
  • the high-pressure water jet is moved over the surface of the workpiece in parallel, non-overlapping movements, so that the surface is processed evenly.
  • a very short machining length can be maintained, so that a very precise guidance of the high pressure water jet over the surface is made possible. Since the individual processing areas do not overlap, the surface is roughened very evenly.
  • the distance between the nozzle and the surface of the workpiece ie the machining distance
  • the pressure of the high-pressure water jet or the pulse frequency can be adjusted so that the surface is machined in the same way everywhere, even if the machining distance changes during machining changes. Since the pulse frequency is controlled by an electromagnetic or piezoelectric valve, it can be adjusted very quickly without the editing management has to be interrupted.
  • the pressure of the high-pressure water jet can also be changed quickly and easily by regulating the power of the high-pressure pump that supplies the device with compressed water.
  • the individual high pressure water jet pulses are clocked in such a way that individual bursts are formed.
  • Each burst consists of a large number of injection pulses, the time interval between the individual bursts being greater than the time interval between the successive water jet pulses.
  • the method can be carried out particularly advantageously with an implant made of metal or a metal alloy.
  • the method is particularly applicable to medical steel or titanium or titanium alloy.
  • the processing of surfaces of ceramic implants is also possible with the method according to the invention.
  • Figure 1 shows the schematic structure of a water jet cutting device with pulsed high pressure water jets
  • Figure 2 is an enlarged view of the nozzle, which is part of the water jet cutting device in longitudinal section,
  • FIG. 3a shows the time course of the water expelled from the nozzle
  • FIG. 3b shows the amount of water ejected when divided into different bursts
  • FIG. 4 shows a hip implant and FIG. 5 shows an illustration of the surface treatment.
  • a water jet cutting device 100 is shown schematically, as it is known from the prior art.
  • the Wasserstrahlschneidvorrich device comprises a tank 1, in which water is held, with which the water jet cutting device is to be operated.
  • the water is fed from the tank 1 via a line 2 to a high pressure pump 3 which compresses the water.
  • the pressure reached is, for example, 2000 to 3000 bar.
  • Via a pressure line 4 the compressed water is passed into a high-pressure sam melraum 5, where a certain supply of compressed water is kept.
  • the high-pressure collecting space 5 is connected via a connecting line 7 to a nozzle 10 from which the high-pressure water jet 14 emerges.
  • the nozzle 10 comprises the one interrupter unit 8 with which the high pressure water jet 14 can be periodically interrupted or released, and a nozzle opening 11 from which the high pressure water jet 14 emerges.
  • the workpiece 15 is at a machining distance d from the nozzle opening 11.
  • the device shown in FIG. 1 is also possible with the omission of the high-pressure collecting chamber 5, depending on the design and performance of the high-pressure pump 3.
  • the nozzle 10 which is part of the water jet cutting device, is shown again enlarged in longitudinal section.
  • the nozzle 10 comprises a nozzle body 12 in which a bore 13 is formed so that a pressure chamber 17 is formed in the interior of the nozzle body 12 which is connected to the connecting line 7 and thus filled with water under high pressure.
  • a valve element 18 here in the form of a nozzle needle, longitudinally movable angeord net.
  • the nozzle needle 18 is moved in the longitudinal direction with the aid of an electrical device, for example an electromagnetic or piezoelectric device, and interacts with a nozzle seat 20.
  • the nozzle needle 18 closes a nozzle opening 11 formed in the nozzle body 12 when it rests on the nozzle seat 20 and releases this nozzle opening 11 when the nozzle needle 18 has lifted from the nozzle seat 20. Then compressed water flows from the pressure chamber 17 into the nozzle opening 11 and forms a high pressure water jet 14. By moving the valve element 18 back and forth, the high pressure water jet 14 is periodically interrupted, so that a pulsed high pressure water jet 14 is created, which hits the surface of the workpiece 15 hits. In order to machine the individual areas of the surface of the workpiece 15, either the workpiece 15 or the nozzle 10 is moved so that all areas of the surface of the workpiece 15 can be machined.
  • the flow rate Q of compressed water in the nozzle 10 is shown over time.
  • the individual water jet pulses 23 are spaced apart from one another in time, the time interval between two water jet pulses being t a , while the pulse duration is denoted by t p in FIG. 3a.
  • the time interval between two water jet pulses 23 is significantly greater than the duration of an individual water jet pulse t p . Since the duration and the time sequence of the individual pulses is determined solely by the movement of the nozzle needle or valve element 18, the frequency and duration of the water jet pulses can be changed over a wide range and the processing of the surface can be adapted to the requirements .
  • the speed at which the high-pressure water jet 14 is moved over the surface of the workpiece or of the implant 15 also has an influence on the machining of the surface of the workpiece 15, in particular on the amount of material that is removed from the workpiece 15.
  • FIG. 3b shows a different time sequence of the individual water jet pulses 23.
  • the water jet pulses 23 follow one another in individual bursts 24, where in this exemplary embodiment two high pressure water jet pulses 23 each form a burst 24.
  • the time interval t ai between two water jet pulses of a burst 24 is smaller than the time interval t a 2 between the bursts 24.
  • the quality of the processing can also be influenced and optimized via the formation and duration of the bursts.
  • a hip joint implant 15 ' is shown as an example, which replaces the hip joint as an endo prosthesis.
  • the hip joint implant 15 ' is designed as a ball joint 27 and has an extension 26 which is introduced into a corresponding recess in the patient's thigh bone in the living body.
  • the ball joint 27 further comprises a ball seat 28 which is inserted into the hip joint socket, where a corresponding recess is also formed during the surgical procedure.
  • Both the pin extension 26 and the ball seat 28 have a surface that is directly comes into contact with the living bone tissue of the patient and is supposed to grow there. The surfaces must be processed accordingly in order to optimally support the growth of the bone tissue. This requires a roughening of the surface, which can be carried out with the method according to the invention.
  • the pulsed water jet 14 is guided over the surface in parallel lines in order to remove just enough material that the desired roughening is achieved. This is shown by way of example in FIG. 5, where the individual machining directions are shown as parallel lines.
  • a suitable machining distance d can ensure that the high pressure water jet 14 does not double over any area of the surface and thus a uniform roughening of the entire surface takes place, which is optimal for the growth of the implant in the living bone tissue.
