Definitions

  • the invention relates to a method for producing an otoplastic, wherein first an individual impression of an ear comprising at least a portion of an external ear canal of the ear is scanned and a three-dimensional model of the impression is created, which then by means of a CAD system to a three-dimensional model the otoplastic is post-processed and arranged relative to a flat base plate, wherein the model is spatially aligned over the base plate and supported by at least one support member on the base plate, the at least one support member connected to the base plate and the model, the model in this orientation a production device is transmitted and the earmold is produced generatively by means of the production device.
  • Otoplastics ie individualized earmolds of hearing aids, housing of miniature earphones for in-ear monitoring (the so-called “button in the ear"), as ear protection or as a jewel to be worn in the ear (as so-called “otofashion”) are increasingly in generative Process manufactured.
  • the fitting - here: the ear mold - is constructed successively in the production device in parallel to the base plate arranged layers.
  • earmolds are also made of metal materials, here essentially made of titanium. Titanium earmolds are not only used - because of their "noble" appearance - for visual reasons, but also for medical reasons: Titanium is anti-allergenic and biocompatible without further coating. A variety of technical advantages (which in turn partially off From a medical point of view, advantage is given to the use of titanium instead of plastic. Thus, the material of the earmold is practically indefinitely resistant to aging, avoids heat build-up in the ear due to its high thermal conductivity and at the same time shields the internal electronics against the electromagnetic field of, for example, an immediately adjacent mobile phone without further measures effective.
  • the higher strength of the titanium also allows the creation of geometries that are not feasible in plastic for stability reasons, such as the mechanical locking of internals - for example of electronic units in faceplates - by threaded or bayonet elements, wall thicknesses up to 0.2 mm, "cage-like "Otoplastics with recesses for comfort, closed cavities to reduce the weight of the earmold and to specifically improve the resonance in certain frequency ranges and the integration of ventilation channels, so-called” ventings ".
  • Base plate facing so-called “overhang surfaces” require on the one hand, if their surfaces have an angle of more than about 45 degrees from the normal, a support on the base plate by supporting elements.
  • the construction of such support elements is basically - for example from the DE 195 07 881 A1 for processes of stereolithography - generally known.
  • these supports can easily be "rubbed off” by hand using plastics after fabrication, they must be chiseled or sawed into metals during fabrication - and then sanded and optionally polished.
  • slanted surfaces inevitably result in step-like structures due to the layered production, which (at least as far as they are intended to be in direct contact with the skin of the auditory canal) requires elaborate post-processing.
  • a temperature gradient arises in layers extending substantially parallel to the base plate between the layers applied over a large area, which can lead to tensions and even distortions and fractures in these structures.
  • the invention has for its object to enable automated positioning of the model on the base plate and thus a partial automation of the production of the earmold.
  • the method according to the invention does not describe a mathematically exact solution of the problem of an optimal arrangement, but rather a systematic trial and error, which deliberately allows a local optimum in individual cases as a result in favor of an economically sensible process.
  • a longitudinal axis of the ear canal footprint is not unambiguous in the mathematical sense, but only a possible meaningful determination of the first test position as the starting position of the method according to the invention.
  • the model is successively aligned in further discrete test positions, which differ from each other and from the first test position either in a degree of inclination of the longitudinal axis relative to the normal of the base plate or in terms of the plane defined by the normal and the longitudinal axis, ie the direction in which the longitudinal axis is inclined relative to the normal. If a point of the longitudinal axis remains constant in space in all test positions, the longitudinal axes in the test positions on the one hand describe discrete cones about the longitudinal axis in the first test position through this point, with the cone's opening angle corresponding to the respective discrete test angle.
  • the projections of the longitudinal axes on the base plate describe a star-shaped beam through this point, each projection extending in one of the discrete test directions.
  • a numerical quality feature of the otoplastic is algorithmically determined which would be obtained if it were manufactured in this test position.
  • the test position in which the numerical value of the quality feature achieves an optimum value in comparison with all test positions, is finally selected for the production of the otoplastic.
  • the model is "fixed" and supported by support elements on the base plate.
  • this quality feature is not to be understood in the sense of a mathematically exact criterion.
  • various features of the earmold to be manufactured can be determined and - also with different weights - used to assess the quality.
  • the quality feature preferably takes account of an overhang surface occurring in the respective test position, the overhang surface being the sum of the projections of all those surfaces of the otoplastic on the base plate whose inclination relative to the normal exceeds an edge inclination.
  • the overhang area in the test position the quality feature achieves a production-technically optimal value in which the overhang area is minimal in comparison with all test positions.
  • a discrete surface portion of the earmold can be defined as an overhang surface, for example, if its surface normal with respect to the base plate, or if the surface piece over the normal by more than 45 degrees (in the sense of a "boundary inclination") is inclined.
  • bottom surfaces ie discrete patches running parallel to the base plate, can be weighted more intensively, as additional warping up to cracks or warping of the surface is to be expected.
  • Undercuts ie areas that are hidden from view of the base plate, on the one hand, can be weighted more intensely with respect to "slope areas" visible from the viewpoint of the base plate, since they pose particular difficulties with regard to the removal of support elements.
  • undercuts in the interior of the model can be weighted at a reduced weight or not scored at all, as support elements attached there are not removed after production.
  • the Quality criteria can be defined, for example, as the area of one of these three types or also as the total area of all types - ie with double weighting of the floor areas - or as standard deviation between the areas of the types in the sense of a "balanced" quality. Depending on the specific requirements, a weighted combination of different sub-features can also be considered.
  • the quality feature preferably takes into account the number of supporting elements required in the respective test position.
  • the number of punctiform support elements as well as the size of the overhang surface is a measure of the cost of the required post-processing of the earmold.
  • the quality feature achieves a production-technically optimal value in which the number thereof is minimal in comparison with all test positions.
  • the quality feature in the respective test position advantageously takes into account an inclination of the faceplate relative to a surface parallel to the baseplate.
  • the installation of electronics allows only very small manufacturing tolerances with respect to the mating surfaces on the earmold: These mating surfaces must not only run perpendicular to the surface of the faceplate, but must not exceed defined roughness, so as not to hinder the assembly of the electronics. These roughnesses are difficult to manufacture with increasing inclination of the mating surfaces relative to the normal, ie the faceplate relative to the base plate and can only be partially compensated by higher compensation of the laser.
  • the inclination of the faceplate is thus a measure of the reject probability of the manufactured earmold.
  • the quality feature achieves an optimum value in terms of manufacturing technology, in which it is minimal in comparison with all test positions.
  • a test position in which the inclination of the faceplate exceeds a marginal tendency is preferably excluded from the further method.
  • a test position in which the inclination of the faceplate exceeds this limit inclination is then not taken into account, in particular in the selection of the test position with the optimum value of the quality feature and under no circumstances selected for the production (even with useful values with regard to other subcriteria).
  • the model is preferably aligned in the first test position with a faceplate lying parallel to the baseplate in the context of a method according to the invention.
  • the outer surface of a faceplate on the one hand represents a contiguous flat surface in the model and on the other hand the contact surfaces of the electronics with the otoplastic run perpendicular to this surface.
  • the surface of a faceplate can usually be determined automatically.
  • the longitudinal axis of the auditory canal footprint is then selected (algorithmically likewise very simply) perpendicular to the plane surface of the faceplate as the normal of this faceplate in order to determine the first test position.
  • each auditory canal footprint starting from a tympanic end has approximately an elongated shape.
  • a longitudinal axis can also be determined automatically using this form by means of generally known algorithms.
  • the automatic recognition of the auditory canal footprint and the determination of a longitudinal axis - for example a center of gravity axis - fails to achieve this auditory canal footprint, this must be determined manually. This can be done by selecting ("clicking") a down-to-align location on the surface of the ear canal footprint.
  • test angles are advantageously selected such that they do not exceed a critical angle.
  • a critical angle represents a particularly simple termination criterion for the method according to the invention.
  • experience has shown that above a limit angle of approximately 45 degrees of angle, as a rule, no arrangements of a model of a real otoplastic that are technically meaningful can be achieved.
  • test positions with a further increased test angle are excluded from the further method.
  • the test position from which the quality feature assumes worse values represents an - at least local - optimum.
  • Such a method according to the invention thus has a (further) termination criterion, which is the search for further - local or global Optima in the considered test direction excludes.
  • the abort criteria described allow in a particularly simple manner a limitation of the computing power required for the arrangement of the model and thus contribute significantly to increasing the efficiency of the method according to the invention.
  • titanium As an alternative to titanium, other metallic materials, ceramics or metal-ceramic sintered mixtures, for example stainless steel or cobalt-chromium alloys which are generally known from uses in dental technology, can in principle also be used with a method according to the invention. Both, however, each have a titanium compared to much higher density and thus a reduced wearing comfort. The use of stainless steel is avoided because of the hardly avoidable nickel content and the associated risk of allergy in the rule.
  • a hearing care professional first takes an individual, three-dimensional auditory canal impression from a hypacusis patient for an in-ear hearing device by means of a commercially available scanner set up for this purpose.
  • the auditory canal data are transmitted in the form of a "point cloud" via TCP / IP to a CAD system with a software specialized for additive manufacturing (for example, the 3Shape A / S system, www.3shape.com) from an external service provider.
  • a first module of the software first generates a volume model of the auditory canal impression from the incoming data and a second module proposes a selection of a section of the auditory canal in which the earmold could be arranged for the in-ear hearing device.
  • the hearing care professional takes over in a web module of the Software proposes or manually selects another section, to which a third module of the software automatically creates a proposal for the arrangement of the sound channels and a faceplate with the electronics.
  • the hearing aid acoustician takes over the proposal via the web module or manually modifies these parameters until the complete geometric definition of a model of the otoplastic to be produced generatively.
  • a further module of the software makes a proposal for the arrangement of the model relative to a planar base plate.
  • the software determines a normal direction of the outer surface of the faceplate and defines a vector in this normal direction through the center of mass of the model as "longitudinal direction "of the auditory canal footprint.
  • the software arranges the model in (virtual coordinate) space so that the longitudinal direction is perpendicular - ie in the z-coordinate direction - with the surface of the faceplate facing upward and correspondingly the eardrum end of the ear canal impression facing down to the baseplate has.
  • the software automatically determines the overhang surface and undercuts and positions required support elements.
  • the software determines the ratio of the sum of projections of the overhang surface and the undercuts to the projection of the entire model onto the base plate.
  • Each required support element is flat rate with a "penalty" of 5 v. H. of the ratio taken into account.
  • the software arranges the model in space so that the longitudinal direction is inclined to the z-coordinate direction in the x-coordinate direction as a test direction by a test angle, which gradually increases from one test position to the next by an angular degree up to a critical angle of 30 angular degrees ,
  • the software determines the quality characteristic in the manner described above. If the quality characteristic increases from one test position to the next, the software aborts the calculation for this test direction. Subsequently, the software executes these steps for all other test directions, with each test direction incrementally rotated in the xy coordinate plane by an angular degree with respect to the previous one.
  • the software proposes the test position for additive manufacturing for which the quality characteristic has the lowest value.
  • the hearing aid acoustician adopts the suggestion or manually selects another of the test positions of the model for the production of the otoplastic shown in a list which can be sorted according to the subcriteria.
  • the geometric description of the selected model including its arrangement relative to the base plate collects the software with the models of other earmolds for generative production on a common base plate and transmits this finally to a manufacturing plant, which generatively manufactures the earmolds by laser welding of titanium powder based on this description ,
  • the earmolds After cooling the base plate with the earmolds this is removed from the manufacturing plant, the earmolds are isolated, manually abraded the respective support elements, ground the attachment points, the earmolds to further improve the surface by means of plastic abrasives trovalinstrument and shipped individually packaged to the respective hearing aid acoustician.
