Definitions

  • the present invention relates to an arrangement according to the pre-characterising part of claim 1.
  • the object of the present invention is to produce an improved fixing of an acetabulum prosthesis. According to the invention this achieved by an arrangement which has the features specified in the characterising part of claim 1.
  • FIG. 1 shows a diagrammatic section through an arrangement according to the invention and figure lb shows a perspective view of the arrangement.
  • Figure 2 shows a diagram of the arrangement according to the invention in situ during dispensing of the bone cement.
  • the drawing 1 generally denotes a cushion-like seal made from an elastic, compressible, rubbery material.
  • the seal 1 which is substantially circular, has a thickness of approximately 10 mm and overall dimensions such that it properly covers the edge of the acetabulum socket, as will be clearly apparent from the following.
  • the seal 1 has a central through-duct 2, intended for inserting the nozzle 3a of a bone cement injection syringe 3 when the seal 1 is applied.
  • the seal has an annular flange la at the opening 2a of the duct 2, which when the seal 1 is applied is intended to face the acetabulum.
  • the seal 1 On the opposite side of the seal, that is to say the side on which the nozzle 3 a is intended to be inserted into the duct 2, the seal 1 has a tubular part lb, which constitutes an extension of the duct 2.
  • the seal 1 On that side of the seal 1, which when it is applied, is intended to face the edge of the acetabulum socket, the seal 1 has an impression 4, which largely has the shape of a circle with the opening 2a as its centre. It should be noted that the diameter d of the tubular extension lb is smaller than the diameter D of the impression 4, for reasons that will be set out below.
  • the acetabular ligament is located in connection with the acetabular notch.
  • a screen-like element 5 immediately inside the impression 4, as is shown in figure lb.
  • Figure 2 shows how the seal 1 is applied when an acetabulum 7, the socket-shaped base 6 of which is formed from cancellous bone, is to be filled with bone cement 8.
  • the impression 4 of the seal 1 bears tightly against the opening edge 5 a of the acetabulum socket, see figure 3, which is achieved due to the fact that the seal 1 is bent by the contact pressure force, indicated by arrows F in figure 2, as a result of the diameter d of the protuberance lb being smaller than the diameter D of the impression 4.
  • the bent shape of the seal is indicated by the dashed line 9 in figure 2.
  • the screen-like element 5 covers the acetabular ligament 10, see also figure 3, but sealing is only achieved when the element, under the ef- feet of the pressure of the bone cement, is pressed so that it bears against the latter.
  • the nozzle 3a is introduced through the duct 2 past the flange la, which is thereby pressed outwards, so that it forms a seal, having a function similar to a non-return valve, around the nozzle 3a.
  • the tubular extension lb functions as a stop, so that the tip of the nozzle 3a projects just far enough out of the seal 1 and at the same time serves as support, in order that the seal 1 can be securely pressed with the requisite affixing force F into tight sealing contact against the edge of the socket-shaped opening in the acetabulum 7.

Abstract

L'invention concerne un agencement dans un joint (1) de forme annulaire, permettant, lors de l'installation d'une prothèse de la hanche au moyen de ciment osseux contenu dans une seringue d'injection (3), de mettre ce ciment sous pression avant l'application de la prothèse dans le ciment. Ce joint (1) présente d'un côté une conduite traversante (2) pour une canule (3a) de la seringue d'injection de ciment osseux (3) et, de l'autre côté, un élément (1b) servant à définir une position prédéterminée pour l'embout de la canule (3b) par rapport à la surface du joint (1) opposée à celle du fourreau de l'acétabule. Au moyen de cet élément, on peut dans un même temps, avec la seringue d'injection (3), presser le joint (1) de manière qu'il entre en contact étanche avec le bord dudit fourreau. Ladite surface du joint (1) présente une empreinte (4), s'étendant de manière circulaire autour de l'ouverture (2a). Cette empreinte (4) comprend un élément écran (5), conçu pour s'appuyer contre le ligament acétabulaire lorsque le joint (1) est appliqué contre le bord du fourreau de l'acétabule.
