Definitions

  • the invention relates to an anchoring means, in particular a surgical anchoring means for fixing suture to a bone.
  • Surgical anchoring means with the help of which suture can be attached to the bone, are already known.
  • An anchoring means designed, for example, in the form of an anchor is described in US Pat. No. 5,258,016.
  • the anchoring means are introduced between tissue and bone or attached to the bone at a distance from the tissue to be fastened.
  • WO 01/103312 A1 shows an anchoring means on which suture material is arranged.
  • This anchoring means can be attached either from outside to inside or from inside to outside.
  • Some of the embodiments of the anchoring means according to WO 01/103312 A1 have grooves for the suture, with the aid of which a guide for the suture material is created. The fixation of the suture takes place via a second element which is pushed onto the grooved element in order to fix the suture to compress material.
  • This anchoring means has the disadvantage that the parts must be applied either outside the bone, whereby only limited locking forces are achieved by the self-tightening seams or that they are anchored in the bone, where the holding force of the anchoring means is significantly lower.
  • the known anchoring means or implants described above are usually introduced into the bone not from outside to inside, but from inside to outside. This usually requires an expansion of the bone canal to at least seven millimeters, which slows down the postoperative healing of the bone.
  • an anchoring means to be used as an implant, which holds the thread material with which the tissue material to be fastened, for example, to a bone, by its shaping directly on the outer bone and absorbs the tension of the thread. Also desirable would be a stepless adjustability of the tension, which receives the thread.
  • the outer opening of the skin should be extended only by a maximum of five millimeters.
  • an anchorage means for fixing suture material in which the anchoring means is formed in two parts, wherein the first part has an internal thread in which at least one tapered groove for receiving the suture is arranged, and wherein the second part in the Internal screw threadable external thread has such that when screwing the second part in the first part at first only partially screwing the second part in the first part of the suture is still movable in the guide while this is completely fixed after at least largely screwing the second part ,
  • a surgical implant for fixing suture material is provided, which allows a stepless tensioning and fastening of the suture material on the bone side opposite the fixation site.
  • the suture can be progressively pulled into the anchoring means and tightened at a point of choice with high pull-out strength and with minimal damage to the suture.
  • the present invention provides an anchoring means in which one or more sutures may be inserted through an opening in one or more tapered grooves. In these grooves, the sutures are first slidably fixed in the first state, while these are firmly connected in the second state by screwing the two parts of the anchoring means.
  • This anchoring means can additionally be supported by a holder which keeps suture taut in the groove during clamping.
  • a setting tool can bring fixative to the bone and keep the suture taut.
  • anchoring means are introduced into the bone through a previously drilled canal which approximates the fixation point. While it was usual in the prior art implants, a fixing device via a introduced from inside to outside target wire in one Distance to the bone from outside to inside, so that the result of the wire perforation skin gap led to a cut length of at least one centimeter, it is now possible to apply the introduced from inside to outside target wire so close to the bone from the outside in that the The skin gap created by the wire perforation must now be opened less than five millimeters. For example, this reduction in cut length significantly improves the free function of a joint after surgery.
  • the anchoring means according to the invention eliminates the need for multiple knotting of the suture that was previously required to tighten the suture.
  • the anchoring means may have a special shape, which is based on the typical occurring bone contour. It should be able to be brought into position by an extension of the cut at the exit point of the target wire of a maximum of five millimeters.
  • the biomechanical properties of the fixation should be at least equivalent to already used implants or implant-free techniques.
  • the first part has an outer shape adapted to the site of implantation.
  • the first part may preferably at least partially have a tapering downwards tapered shape of a cone, whereby the implant thus oriented at the typical Bohrkanalwinkel that occurs in a fixation of tendons in a joint - this is often 45 ° - oriented.
  • the thus producible outer support of the anchoring means used as an implant is therefore optimized according to the situation in the anchoring.
  • the anchoring means is advantageously made of metal, very particularly advantageously of a biocompatible metal, such as titanium or plastic, particularly preferably of a resorbable plastic.
  • a biocompatible metal such as titanium or plastic
  • several grooves with different dimensions can be used. be provided.
  • different thickness suture can be used. It is also possible to insert several suture materials into, for example, a larger groove.
  • the first part of the anchoring means may be formed at least over a part of the outer surface polygonal, preferably hexagonal. This makes it possible that the first part of the anchoring means can be fixed by means of a correspondingly fitting wrench.
  • the first part of the anchoring means may further comprise sharp edged supports and / or extensions for better anchoring in the bone.
  • the second part of the anchoring means is designed as a screw with a screw head.
  • the screw head can be flattened and even for receiving a screwdriver, for example, have a slot or a Phillips.
  • the screw head has a hexagonal or star-shaped recess for receiving a correspondingly shaped screwdriver tip.
  • the anchoring means can advantageously be guided by the threads to be fixed to its position on the bone.
  • an instrument adapted for this implant can be provided for setting the anchoring means and for expanding the skin and tissue as well as for accurately separating the threads.
  • Figure 1a and Figure 1b a first embodiment of an inventive
  • Anchoring agent in the representation of the side and in a section AA, wherein the anchoring means is shown in a first position and
  • an anchoring means 10 that can be used as an implant consists of a first part 12 and a second part 14.
  • the first part 12 is designed in the form of a screw nut having an internal thread 16.
  • the first part is conically tapered downwards.
  • a hexagonal flattening 18 is formed, which serves to receive a correspondingly shaped wrench (not shown here).
  • the first part in the region of the internal thread 16, the first part, as shown in FIG. 1b, has a groove 20 for receiving a suture 22. More precisely, two grooves 20 are provided in the embodiment shown here, which are formed here opposite one another. Through a groove, the suture 22 is pulled, while in the other groove 20 no suture is retracted.
  • the second part 14 of the anchoring means 10 consists of a screw 24 with screw head 26.
  • a slot 28 is provided for receiving a screwdriver, not shown here.
  • the screw 24 has a thread which fits into the internal thread 16 of the first part 12.
  • Both parts 12 and 14 of the anchoring means 10 are made of a self-dissolving or degradable plastic material, as it is already well known in the implants used in surgery.
  • the second part 14 is only partially screwed into the upper part of the first part 12. Due to the shape of the grooves 20 provided in the first part 12, the thread of the screw 24 engages not yet firmly in the suture 22, so that it is still movable in the guide groove 20.
  • the anchoring means described above can be used very advantageously for a band reconstruction on the knee joint.
