Definitions

  • the invention relates to a sti m prosthesis for insertion into a fistula between the esophagus and
  • Trachea comprising a cylindrical centerpiece with a cylindrical passage, at each end of the centerpiece an outer flange projecting from the centerpiece and a flap which cooperates with a seat arranged in the passage at one end of the centerpiece, the centerpiece, the flanges and the flap being made of the same material are formed from a flexible material.
  • a voice prosthesis of this type is disclosed in DE-T2-690 03 817, in which the ring consists of a material that is stiff in relation to the flexible material, and is arranged in the middle near the seat to stiffen the seat and also itself can form the seat. It may be difficult to insert the prosthesis into the fistula because the stiffness of the ring means that the prosthesis offers resistance to the insertion and the fistula must therefore expand during insertion.
  • the object of the present invention is to eliminate this difficulty and to provide a voice prosthesis of the type mentioned which can withstand movements in the surrounding muscles which could deform the prosthesis and risk the function of the valve, without uncomfortable pressure against the walls of the esophagus and trachea.
  • a ring which forms the seat consists of a flexible or soft material and is glued into the center piece.
  • the drawing shows a longitudinal sectional view of a voice prosthesis according to the invention.
  • the voice prosthesis shown in the drawing comprises a cylindrical middle piece 1. At each end, the middle piece forms an outwardly projecting, annular flange 2 or 3.
  • the one flange 2 is provided after the insertion of the prosthesis into the throat for contact with the inside of the trachea , and the other flange 3 should lie on the inside of the esophagus after insertion in the throat.
  • the center piece 1 is provided radially inward from the flange 3 with a circular valve flap 4 which is integrated with the center piece or is made of the same material.
  • the valve flap 4 is cut free from the central part along most of its circumference, so that a short circumferential section remains, which forms the joint of the valve flap.
  • the valve flap is comparatively thin, and the joint has a very low bending resistance, so that very little pressure is required to open the valve.
  • An obliquely cut cylindrical section 6 forms an extension of the cylindrical middle piece 1 beyond the flange 3.
  • the hinge is located at the section 6 of the extension of the centerpiece that is most cut out, but the hinge can also be located in other positions. Section 6 protects the sensitive valve flap from external influences. All parts of the prosthesis described above are made of silicone rubber in the illustrated embodiment. If the centerpiece is off Is silicone rubber, the adhesive is preferably a silicone glue that can be medically accepted.
  • valve flap Axially inwards from the valve flap is in the
  • Center piece 1 formed an inner groove in which a ring 5 is inserted.
  • the ring is made of a flexible material, e.g. made of the same material as the above-mentioned parts of the prosthesis, for example silicone rubber.
  • the inner diameter of the ring is selected so that the inner circumference of the ring forms an extension or continuation of the inner diameter of the center piece. The inside diameter is thus essentially constant over the entire length of the prosthesis.
  • the ring is glued in the middle piece 1, and an annular end section of the ring forms the seat for the valve flap 4.
  • the glued flexible or soft ring 5 forms together with the center piece 1 a unit which can be inserted into the fistula without difficulty but is not easily squeezed, so that the sensitivity of the valve to muscle movements in the surrounding muscles, e.g. when swallowing, is significantly reduced, and in fact without the prosthesis being so stiff that it causes uncomfortable pressure when inserted into the fistula or after insertion against the wall of the esophagus adjacent to the flange 3.

Abstract

L'invention concerne une prothèse vocale à insérer dans une fistule située entre l'÷sophage et la trachée-artère, qui comprend unepièce médiane (1) cylindrique pourvue d'un passage cylindrique, un rebord extérieur (2 et 3) situé en saillie à chaque extrémité de ladite pièce médiane, et un clapet (4). Ces pièces sont moulées dans un même matériau souple. Le clapet coopère avec un siège monté dans le passage, à une extrémité de la pièce médiane. Ce siège est formé par une bague (5) réalisée dans un matériau souple ou non rigide et est collé dans la pièce médiane.
