Definitions

  • the invention relates to a method for producing and / or correcting dimensions of auxiliary parts adapted to areas of a living body with a matching surface, in particular auxiliary parts having an orthopedic function.
  • the invention further relates to a measuring device for performing such a method.
  • auxiliary parts in particular denote prostheses of limbs such as lower leg and thigh prostheses or corresponding arm prostheses, but also support corsages, cuffs, orthopedic shoes, footbeds for shoes, sitting pools and the like.
  • the invention is based on the technical problem of significantly improving the adaptation without any special effort in the production and / or dimensional correction of auxiliary parts adapted to areas of a living body.
  • the invention is also based on the object of specifying a measuring device which is particularly suitable for the method according to the invention.
  • the subject of the invention is a method for the production and / or dimensional correction of auxiliary parts adapted to areas of a living body with a fitting surface, in particular auxiliary parts with an orthopedic function, with the following method steps:
  • a flexible membrane which belongs to a stationary pressure medium chamber
  • the pressure medium chamber is brought under an adaptation pressure with the aid of a pressure medium and is pressed with the adaptation pressure to the region of the body to which the auxiliary part is to be adapted, the region of the body being compressed under the influence of the adaptation pressure,
  • CAD Constructing
  • the aid being built in accordance with the adaptation surface determined in this way.
  • the invention is based on the knowledge that the poor adaptation of prostheses and other auxiliary parts adapted to a living body described at the outset is based on the fact that the measurement on which the adaptation is based, even if this is carried out with the aid of computer tomography, without any load on the corresponding area of the living body.
  • the surface of the area which can be recognized by computer tomography deforms when the auxiliary part is put on by the wearer of the auxiliary part and the corresponding area of the body experiences the loads which are common in everyday life.
  • the adaptation surface does not match the assigned area of the living body, which adjusts and wants to adjust during exposure, and consequently pressure points and free spaces are the result.
  • pressure is applied when measuring the areas of the living body to which an auxiliary part is to be fitted, as described, namely with the adaptation pressure.
  • This creates a hydrostatic or aerostatic tension, as it were, encompassing or exerting pressure on the body part, depending on whether the pressure medium is a liquid or a gas.
  • the resulting deformation of the area of a living body to be provided with the auxiliary component during the measurement does not completely correspond to the deformation, it occurs when an or manufactured by the method according to the invention
  • the method according to the invention can be carried out in various ways.
  • the auxiliary part is manufactured in a computer-aided manner by metal-cutting shaping in accordance with the adaptation surface determined according to feature f) from claim 1.
  • the measurement according to feature d) from claim 1 is preferably carried out with the aid of laser beam measuring devices operating according to the triangulation principle.

  • Fig. 2 shows a vertical section through a further he measuring device according to the invention.
  • the basic structure includes a stationary receptacle 1 for the body part stump 2 to be measured, a stationary pressure medium chamber 3 with a retaining ring 4 with a round cross-section, for a flexible membrane 5 and a measuring medium carrier 6 with a laser beam transmitter and a laser beam receiver concentrically surrounding the pressure medium chamber Triangulation measuring device 7 for the surface measurement on the area of the body to be measured.
  • the measuring medium carrier 6 can be driven about the axis 8 of the receptacle 1 for the body part stump 2 to be measured and the laser beam transmitter and laser beam receiver can be moved up and down on the rotating measuring medium carrier 6.
  • the measured values determined in this way can be recorded and processed in a known manner, for which purpose a large number of known evaluation devices are available.
  • the area of the body to which the auxiliary part is to be adapted is fixed in position, namely is inserted into a corresponding receptacle 1.
  • the position-fixed region of the body is covered by the flexible membrane 5, which belongs to a fixed pressure medium chamber 3.
  • the pressure medium chamber 3 is placed under the adjustment pressure with the aid of the pressure medium and is pressed with the adjustment pressure to the area of the body 2 to which the auxiliary part is to be adjusted, this area of the body itself being subjected to a corresponding pressure.
  • the surface of the specified area of the body in the exemplary embodiment of a body part stump is measured with respect to a fixed coordinate system via the pressed membrane 5.
  • the measured values of the measurement are stored electronically and then processed with computer-aided construction means and then the adaptation surface of the auxiliary part is manufactured with the aids of modern manufacturing technology, namely with computer-aided construction means and corresponding production means.

Abstract

L'invention concerne un procédé de production et/ou d'ajustement dimensionnel de pièces auxiliaires pourvues d'une surface d'adaptation et adaptées à certaines parties d'un corps vivant, notamment de pièces auxiliaires à fonction orthopédique. La partie du corps à laquelle la pièce auxiliaire doit être adaptée, est fixée en position et est ensuite recouverte d'une membrane souple qui fait partie d'une chambre de milieu de pression fixe. La chambre de milieu de pression est amenée à une pression d'ajustement à l'aide d'un milieu de pression et est pressée contre la partie du corps à laquelle la pièce auxiliaire doit être adaptée, à l'aide de la pression d'ajustement, ce qui comprime ainsi la partie du corps concernée. A l'aide de la membrane pressée contre la surface de la partie du corps concernée, ladite surface est mesurée par rapport à un système de coordonnées fixe. La pièce auxiliaire est réalisée en fonction de la surface d'adaptation ainsi déterminée. L'invention concerne également des dispositifs de mesure pour mettre le procédé en ÷uvre.
