Definitions

  • the invention relates to an insertion instrument for total hip arthroplasty for inserting socket inserts into endoprosthetic acetabular cups according to the preamble of claim 1.
  • Figure 1 shows a sectional view of a hip pan (hatched) according to the prior art with inserted socket insert, which is coupled via a conical clamping with the acetabular cup.
  • Figure 2 shows a sectional view of a H ⁇ ftpfanne (hatched) according to the prior art with tilted inserted pan insert.
  • the gripping of the upper outer edge of the socket insert by the instrument is usually carried out via a so-called three-point recording.
  • the instrument has to claw-shaped elements which protrude at least three points beyond the outer edge of the socket insert and each exert on a point-shaped point below the end face of the socket insert a normal force or friction force.
  • the alignment of the instrument with Pfannenson is usually done by placing the instrument on the end face of the acetabular cup or on elements (eg recesses or elevations) near the end face, which in turn lie in a plane parallel to the end face.
  • Insertion instruments which rest on the entire end face of the acetabulum for aligning the acetabulum insert, can be supported by bone and bone
  • the insertion instrument according to the invention is characterized in that the support member encloses a freely accessible substantially circular effective through-hole, the center of which is located on the longitudinal axis of the Einsetzinstrumentes.
  • the substantially circular effective penetration area must be large enough that a finger of the user or surgeon is push-through.
  • the penetration area must be so small that the insertion instrument has sufficient stability and on the other hand must not be so small that fingers of the user are not sousteckbar.
  • the effective diameter of the through-hole area is greater than or equal to 2.0 cm, more preferably greater than or equal to 2.5 cm.
  • effective diameter in a support element which surrounds a circle as a through-hole (see Figure 3), the diameter of the circle. However, if the support element encloses a penetration area other than a circle, as shown in FIGS. 7a, 7b and 8, the effective diameter is the diameter of the inscribed circle (see FIG. 7a, reference numeral 20). By effective diameter is meant the diameter of the user's finger rather than the area (see Figure 7a, reference numeral 21) of the through-hole, which is essentially irrelevant to the insertion of the finger.
  • the spring elements and the support element are combined to form a one-piece support spring element and the retaining claws are arranged on the support spring element.
  • the insertion instrument is in one piece and is easy to manufacture.
  • the support spring element is an elastically yielding ring, wherein the retaining claws are arranged on the outer circumference of the ring.
  • the retaining claws For placing on the outer edge of the socket insert, the retaining claws must be pushed only by a radial clamping over the outer edge of the socket insert, that is, the support spring element is deformed and acts on the retaining claws a spring force.
  • each retaining surface of the retaining claws exerts a compressive force on the socket insert, which is the magnitude and direction of the spring force on the respective retaining claw.
  • the support spring element has a triangular or n-corner shape. Also a concertina-shaped form may be advantageous. It is always important to ensure that the effective penetration area is large enough that a finger is push-through. By designing the shape of the support spring element, the spring force can be adjusted.
  • the support element and the spring elements are separate components and the retaining claws are connected via the spring elements to the support element.
  • the spring elements have a concertina-shaped form, which are preferably arranged perpendicular to the plane of the retaining claws.
  • the support spring element or the support elements between the holding claws to produce more rigid and flexurally soft zones in its height and width varying cross-section.
  • the support spring element or the support elements can also have a change in cross-sectional geometry between the retaining claws to produce more rigid and flexurally soft zones.
  • FIG. 3 shows an insertion aid according to the invention consisting of an annular, resilient support-spring element 12 with retaining claws 2.
  • the insertion instrument consists in this embodiment of a resilient, annular support spring element 12, which is followed by three retaining claws 2.
  • the design of the Einsetzinstrumentes takes place in manufacturing technology advantageous as a monolithic component, which can be produced for example by injection molding.
  • the flexibility of the support spring element 12 causes the retaining claws 2 can be moved radially. With increasing radial displacement of the retaining claws 2 thereby increases the spring force to be overcome.
  • the force-displacement characteristic of the retaining claws 2 can be influenced by appropriate geometric design of the annular support spring element 12.
  • the retaining claws 2 each have a retaining surface 3 (see FIG. 4).
  • the retaining claws 2 lie with their lower end 6 (see FIG. 6) in the assembled state on an outer surface of the socket insert 17.
  • the support spring element 12 is in the cap 5 of the socket insert 17 and the retaining claws 2 engage over the end face and outer edge of the socket insert 17.
  • the support spring element 12 and the retaining claws 2 in a plane lie above the cap 5 of the socket insert 17.
  • FIG. 4 shows an insertion aid according to the invention with a visible holding surface 3.
  • each support surface 3 exerts a compressive force on the socket insert 17, which is the spring force on the respective holding claw 2 amount and the same direction. Due to the pressure forces acting frictional forces between the holding surfaces 3 and the outer surface of the socket insert 17, which counteract a removal of the insertion of the pan insert 17. This is essential for the function of the Einsetzinstrumentes.
  • FIG. 5 shows a socket insert 17 with an insertion instrument according to the invention in the mounted state.
  • the retaining claws 2 come at its lower end 6 in contact with the end face of the acetabulum 18. Since the retaining claws 2 all have the same extent down, the contact points form a plane which both to the end face of the acetabular cup 18 and to the end face of the cup insert 17th is parallel. Thus, this also results in an orientation of the two end faces, so that they are parallel to each other. A possible tilting of the socket insert 17 is counteracted. By still existing at this time, lateral gap between socket insert 17 and acetabulum 18 a slight displacement of the socket insert 17 in the acetabulum 18 is possible.
  • FIG. 6 shows a socket insert 17 with an insertion instrument according to the invention in the assembled state when inserting the socket insert 17 into the acetabular cup 18.
  • the spring element or the supporting spring element 12 returns to its original shape.
  • the insertion instrument is further pressed off the end face of the acetabulum 18 and slides a few inches along the finger 7 of the user until the movement of the Einsetzinstrumentes comes to a standstill. If the user wears rubber gloves, as is the case during surgery, the inserter will stick to the user's finger through the glove. As a result, the user will inevitably remove the insertion instrument from the surgical field as he removes his hand from the surgical field.
  • Figure 7 shows two different insertion instruments in the view from above.
  • a variation of the geometry of the annular compliant element may be e.g. by a triangle ( Figure 7a) or n-corner shape ( Figure 7b) happen.
  • Figure 8 shows an inventive insertion in the top view with a direct connection of the three retaining claws 2 by accordion-shaped spring elements or support spring elements 12 or connecting lines 13 between the jaws. 2
  • FIG. 9 shows an insertion instrument according to the invention in a top view (FIG. 9a) and in a sectional view (FIG. 9b).
  • the connection of the three retaining claws 2 takes place with a central ring or support element 15 by zieharmomka-shaped spring elements 16, which are arranged perpendicular to the plane of the three retaining claws 2. At these spring elements 16, the retaining claws 2 are attached.
  • a variation of the cross section of the annular, resilient element, or of the supporting spring element 12 can take place in cyclic form over the circumference of the annular, resilient element or supporting spring element 12.
  • the force-displacement characteristic of the retaining claws 2 and the shape of the annular, resilient element or the supporting spring element 12 can be influenced during the deformation.
  • possible torsions of the annular element during the deformation can be deliberately suppressed or influenced, for example if an undesired tilting of the retaining claws 2 on the edge of the socket insert 17 or the acetabulum 18 could occur due to torsions.
  • the variation of the cross section can be done by changing its height and width, so that bending soft and rigid zones arise, for example, rigid zones in the region of the retaining claws 2 and flexible zones in the area between the retaining claws 2, see Figure 10.
  • FIG. 10 shows an insertion instrument according to the invention (cutout between two retaining claws) with varying ring cross-section - variation of height and width of the cross section for producing more rigid and more bendable zones.
  • FIG. 11 shows an insertion instrument according to the invention (section between two retaining claws 2) with a varying annular cross-section. Variation of the cross-sectional geometry from a rectangular shape to a circular shape and back to a rectangular shape.
