Definitions

  • the invention relates to a method for connecting at least two structural parts of an orthopedic component, in which the structural parts are retained in an orienting device while oriented in relation to each other with an intermediate space thus being formed between the structural parts.
  • the invention also relates to an orthopedic component having at least two structural parts which are adhesively bonded to one another at a distance from one another.
  • Structural parts in particular those formed from pre-fabricated semifinished products based on fiber-reinforced plastics, can be connected to one another in various ways. Besides a screwed connection, in which case through-holes are formed or made through both structural parts, through which holes threaded bolts are fitted and connected to one another, it is also possible for the two structural parts to be adhesively bonded to one another.
  • the parts are oriented in relation to one another, are held in relation to one another in the oriented form, and an intermediate space is formed between the structural parts, which space is filled with an adhesive.
  • the assignment of the two parts is maintained for as long as it takes for the adhesive to become sufficiently cured.
  • the retaining devices provided as appropriate are then removed and the adhesive that routinely escapes via the joint area is removed within the scope of a finishing operation. This finishing operation is laborious and can only be carried out by means of time-consuming, manual work.
  • the object of the present invention is to provide a method for connecting at least two structural parts of an orthopedic component and also an orthopedic component as such, which can be realized more economically, ensure a precise orientation of the structural parts in relation to one another, and reduce the finishing effort.
  • the method for connecting at least two structural parts of an orthopedic component, in which the structural parts are retained in an orienting device while oriented in relation to each other with an intermediate space thus being formed between the structural parts makes provision for the orienting device and the structural parts to together form a hollow space, which is fluidically connected to at least one feed connection and via which an adhesive for adhesively bonding the structural parts is introduced into the hollow space.
  • the hollow space is delimited at least in part by the structural parts so that the introduced adhesive comes into contact with the structural parts and can adhesively bond these to one another.
  • the hollow space preferably also has an outlet channel so that, when the adhesive is introduced into the hollow space, the air can be displaced so that the hollow space can be completely filled.
  • the feed connection and outlet channel are closed, and the adhesive is left to cure.
  • the adhesive in the cured state preferably has resilient properties, for example in the case of a foot prosthesis so as not to tear or fracture as the prosthetic foot rolls from heel to toe.
  • PU, TPU and/or TPE are preferably used as adhesives.
  • resins can also be used, which in particular is advantageous in the case of fiber-reinforced material, since the same resins used to form the matrix of the fibers can be used, thus resulting in a good connection between the structural parts and the adhesive.
  • the structural parts are retained oriented in relation to one another until the adhesive has cured.
  • This can be achieved for example in that receptacles, slots and guides are arranged or formed in the orienting device so that the orienting device is automatically secured to the structural parts.
  • the structural parts it is possible for the structural parts to be fixed to the orienting device via a clamping device or another fixing device, for example by means of a clamp, so that, even when the adhesive is fed under pressure, the orientation of the structural parts in relation to one another is not cancelled.
  • an additional orientation of the structural parts in a plane can also be provided via an apparatus or an auxiliary device.
  • the auxiliary device or apparatus can ensure the orientation in another plane or orientation, so that the orienting device does not on its own position the structural parts in relation to one another.
  • the auxiliary device ensures the orientation in another plane or orientation, and by way of example an edge can be spared and the orientation and positioning of the free ends of the structural parts can be implemented via the auxiliary device, for example the press or a clamping device.
  • At least one structural part is advantageously embedded in the adhesive, wherein there is no need for complete embedment in the adhesive, rather it is sufficient when at least one structural part comes into contact with the adhesive at more than one surface, for example on an upper side and a lower side or on a number of side faces, in order to provide an adhesive bonding of the structural part on a number of sides.
  • a development of the invention makes provision for at least one structural part to be pressed during the adhesive bonding against the orienting device, whereby it is not necessary to design the orienting device as an independently sealing mold part assigning the structural parts to one another. It is thus sufficient for a region above a first structural part, which region rests on the surface of the first structural part and is upwardly open, to be surrounded via spacers and a peripheral edge.
  • This upwardly open receptacle which for example can have guide edges for the second structural part, is closed by the second structural part in that the second structural part is placed against the orienting device and is acted on by a force in the direction of the first structural part.
  • the hollow space is sealed by holding the structural parts, naturally inclusive of the feed connection and the outlet channel, so that a substantially closed hollow space is produced, from which the fed adhesive can escape only through the outlet channel. Due to the practically complete sealing of the hollow space or the hollow spaces, it is possible to avoid finishing operations or to reduce these to a minimum.
  • the adhesive can be introduced into the hollow space via feed devices, for example feed tubes, wherein the feed devices and where applicable also outlet devices such as outlet tubes remain on the orienting device until the adhesive is cured and are removed once the adhesive has cured.
  • feed devices and where applicable outlet devices such as tubes, pipes and the like can be formed as separate components which are inserted into the relevant channels and prevent adhesive from coming into contact with the surface both of the structural parts and of the orienting device as said adhesive cures.
