Definitions
- the invention relates to a bone clamp according to the preamble of claim 1.
- Bone clips are already known from the prior art, which consist of a memory metal alloy and have a transition temperature in the range of the body temperature.
- the disadvantage of these bone clips is the need to either freeze the bone clip in the refrigerator or to heat the bone clip after implantation with a special heating device (e.g. a coagulator), which can lead to necrosis.
- the invention seeks to remedy this.
- the invention has for its object to provide a bone clip, which exerts a compression effect on the bone fragments connected to the bone clip solely due to its elastic deformation - brought about by means of a suitable instrument.
- the bone clip according to the invention can also be made from a memory metal alloy; however, their function is based solely on the elastic deformation of the clamp, so that neither cooling nor heating the bone clamp is necessary.
- the invention solves the problem with a bone clip, which has the features of claim 1.
- Another advantage lies in the fact that the legs of the bone clamp are inserted into the bone fragments in a parallel state, so that a uniform distribution of the compression force along the two legs is ensured.
- the bridge of the bone clamps is preferably elliptical, but a rhombus-shaped or diamond-shaped bridge can also be used.
- the bone clamp consists of a material that has a non-linear stress-strain diagram.
- the bone clip can advantageously be made from a memory metal alloy, preferably from a nickel-titanium alloy, but without its compression effect being based on the memory effect.
- the memory metal alloy can have a transition temperature of higher than 50 ° C, preferably higher than 80 ° C. Typically that is
- the bone clip can in particular consist of a nickel-titanium alloy, wherein
- Such a material is particularly biocompatible and highly elastic.
- the bone clamp can also be made of a nickel-free, elastic material be made, which is advantageous for nickel allergy sufferers.
- the bone clip can also consist of a plastic, preferably polyether ether ketone (PEEK) or a carbon fiber reinforced PEEK. This has the advantage that the bone clamp can also be used for people with nickel allergies.
- PEEK polyether ether ketone
- the two free ends of the two legs of the bone clamp are either pointed or blunt.
- the blunt design requires pre-drilling, the blunt bone clamp can also be used bicortically and no soft parts are injured.
- the cross section of the two legs of the bone clamp can also taper towards their free ends.
- the cross section of the two legs is non-circular, preferably rectangular.
- the cross-section of the two legs should advantageously be at most 2.0 mm, preferably at most 1.6 mm in each direction and / or at most 2.5 mm 2 , preferably at most 2.0 mm 2 , in order thereby to be less invasive.
- the two legs In the compressed state of the bridge, the two legs should advantageously be able to exert a compression force of at most 1 MPa.
- the two legs should expediently have one when the bridge is compressed
- the width of the bridge in the compressed state should be at most 6 mm, preferably at most 5 mm. This makes the bone clamp less invasive, especially when used in the hand, foot and face area, i.e. in places where there are only a few soft tissues and a wider clamp could lead to soft tissue irritation.
- the preferred dimensioning also has cosmetic advantages because larger clips would be applied under the skin.
- the two legs of the bone clamp can be three-dimensionally structured Have surface, preferably in the form of transverse ribs or transverse grooves. This prevents the bone clamp from slipping out after implantation.
- pliers are suitable as an instrument for the elastic deformation of the bone clamp, which comprises means for simultaneously compressing the bridge and deforming the bridge, such that the two legs of the bone clamp are at a greater distance from one another and at the same time are oriented essentially parallel to one another.
- the pliers can also be designed such that the distance between the two legs is increased and their parallel alignment takes place independently of one another.
- the two legs can also be aligned in parallel at their upper end - shortly before the transition to the bridge - without the bridge having to be bent out of its plane (i.e. facing away from the legs). This can be done, for example, using a suitable pliers-shaped instrument.
- Figure 1 is a schematic, perspective view of the bone clamp according to the invention in the untensioned state.
- Fig. 2 shows the clamp of Fig. 1 in the tensioned state, as it is used in two bone fragments.
- the bone clamp 1 shown in FIG. 1 is in the untensioned state. It has two legs 2, 3, which each have a free end 4, 5 and a rear end 6, 7, the two rear ends 6, 7 being connected to one another via an elastically deformable bridge 8.
- the two legs 2, 3 define a level 9, which corresponds to the drawing level.
- the two legs 2, 3 converge in such a way that their two free ends 4, 5 are closer together than their two rear ends 6, 7.
- the free ends 4, 5 of the two legs 2, 3 are designed such that they are pointed so that they are suitable for insertion into a bone.
- the free ends 4, 5 can, however, also be of blunt design, since pre-drilling generally takes place anyway.
- the bridge 8 has essentially the shape of a closed curve, namely an ellipse, the two legs 2, 3 being attached to the end points of the major axis of the ellipse.
- the bridge 8 designed as an ellipse lies essentially in a plane 10 which is perpendicular to the plane 9 of the two legs 2, 3.
- the elliptical bridge 8 can be elastically deformed in such a way that the distance between the two rear ends 6, 7 of the two legs 2, 3 increases and at the same time the two legs 2, 3 are aligned essentially parallel, as shown in FIG 2 is shown.
- the deformation of the bridge 8 takes place on the one hand by compressing the elliptical bridge 8 in the area between the two legs 2, 3 - as indicated by the two arrows 11 in the plane 10 - and on the other hand by bending the bridge 8 in the area of the the rear ends 6, 7 of the two legs 2, 3 against the direction of the free ends 4, 5 relative to the area between the two legs 2, 3 as indicated by the arrows 12 in the plane 9.
- the compression of the bridge 8 in the direction of the arrows 11 causes the elliptical shape to flatten out, so that the distance between the two rear ends 6, 7 of the two legs 2, 3 is increased.
- the bending of the bridge 8 in the direction of the arrows 12 leads to a spreading of the legs 2, 3 so that they are aligned parallel to one another.
- the bone clamp 1 can be inserted into the adjacent bone fragments 12, 13 by means of the (not shown) tensioning instrument. If the tensioning instrument is now removed, the elastically deformed bone clamp 1 tries to return to its original undeformed shape. In this endeavor, the two legs 2, 3 exert a compressive force on the bone gap 14 lying between the two bone fragments 13, 16, as is indicated by the arrows 15 in the plane 9. This keeps the bone gap under constant compression, which promotes healing of the fracture.
- Typical dimensions for the bone clamp according to the invention in the uncompressed state are: 5-20 mm for the length of the legs 2, 3 and 8-30 mm for the length of the bridge 8.
