Abstract

The invention relates to an implant for fixing an articulated joint. To simplify the use of said implant, the inventive device provides that it is designed as a U-shaped clip comprising a bar and arms which extend laterally at the ends of said bar, whereby the clip consists of a shape memory material which changes form with an increase of temperature from a martensitic low temperature state into an austenitic high temperature state, and there is a greater distance between the arms in the low temperature state, which lies below body temperature, than in the high temperature state, which is reached when the clip is heated to body temperature.

Description

IMPLANT FOR DETERMINING THE FACETS HINGE

The invention relates to an implant for fixing of the facet joint.

When damage to the spine, it is often necessary to connect together adjacent vertebral bodies by bone fusion. This can be done by providing a distance body is inserted between adjacent vertebral bodies in place of the removed intervertebral disc, in particular a spacer body which can be penetrated by bone material. Although such fixation in many cases sufficient, it is desirable in other cases still make a connection of the adjacent vertebral bodies in the dorsal part of the spinal column, in addition, specifically in the region of the facet joint, which abut the adjacent vertebral bodies together. A compound in this field leads to an additional stabilization of the adjacent vertebral bodies and thereby promotes the complete fusion of the vertebral bodies.

It is known to determine the facet joint characterized in that bone screws are threaded through the two parts of the facet joint so that the joint surfaces are thus fixed relative to each other. However, this is complicated and requires a considerable amount of time.

It is an object of the invention to provide an implant with such a compound of the facet joint in

BESTATIGUNGSKOPIE easily can be made and very effective.

This object is achieved with an implant for defining the facet joint according to the invention in that it is designed as a U-shaped bracket having a web and having at its ends protruding laterally from it poor in that the clip consists of a Formgedachtnismaterial that when the temperature increases under deformation transitions from a martensitic low-temperature state to an austenitic high-temperature state, and the arms in the low temperature state that is below body temperature, at a greater distance from one another than in the high temperature state, which is achieved in body temperature during heating of the bracket.

Such a clamp-shaped implant can be introduced in the low temperature state with its arms in the two parts of the facet joint, share, for example by hammering or after a preparation of a corresponding insertion hole in the Facettengelenk- by inserting the arms into these holes, and during the subsequent heating of the clip on body temperature goes over this from the martensitic state to the austenitic state, with the arms of the clip converge there, and thereby press the two parts of the facet joint against each other and lock out. The insertion of such a clip is cooled quickly and easily accomplished, and the subsequent fixing of the two parts of the facet joint against each other by clamping the joint surfaces is carried out automatically by the warm-up of the clamp. This yields for the operator a simple and very effective method for fixing the facet joint.

The transition from the martensitic state to the austenitic state can also be effected at a temperature which is above body temperature. Such a transition is then caused by targeted heating of the bracket. Because of a hysteresis characteristic of alloys of a back transition from the austenitic state to the martensitic state takes place at a considerably lower temperature which is below body temperature, so that the clip also remains in a tensioned state, when the body temperature is lower than the transition temperature from the martensitic state to the austenitic state.

Another important advantage of the implant as described is that this implant endoscopes pisch, that is through a trocar sleeve and into the body can be used, this is for only fasten the vertebral bodies bung in the region of the facet joint because of the thereby necessary orientation of screws not possible.

It is particularly advantageous when the arms of the bracket are of different lengths, so that a formfitting insertion is enabled in the facet joint in this manner is. For example, it can be provided that the length of one arm between 8 mm and 12 mm, and that of the other arm between 12 mm and 25 mm.

The clamp may preferably be bent from a round metal.

In another embodiment, the bracket consists of a sheet metal strip, in particular a cold-rolled sheet.

It is advantageous if the arms have sharp outgoing ends, this assists the driving of the staple into the two parts of the facet joint.

The arms may be in the cryogenic state at a distance between 8 mm and 25 mm, which is reduced in the high temperature condition at 6 mm to 23 mm.

In a first preferred embodiment it is provided that the approach of the arms by changing the angle between the bridge and arms takes place.

However, it is also possible that according to another preferred embodiment carried out the approach of the arms by an arcuate deformation of the stretched in the low temperature state of the web; this deformation modes can also be combined where appropriate.

The following description of a preferred exemplary form of the invention serves in conjunction with the drawings for a more detailed explanation. In the drawings: Figure 1 is a side view of two partly illustrated respectively adjacent vertebral bodies, the facet joint is fixed by inserting a clip;

Figure 2 is a sectional view taken along line 2-2 in Figure 1;

3 shows a bracket for fixing the facet joint in the low temperature state with spaced apart arms, and

Figure 4 is a perspective view of another preferred embodiment of a clip.

In Figures 1 and 2 shows two juxtaposed vertebral body 1, 2, which are held by means disposed between them disc 3 at a distance from each other. The disc 3 is flexible and allows, within certain limits tilting of the adjacent vertebral bodies against each other, this tilting is guided and limited by both sides dorsal provided on the vertebrae facet joints 4, which are formed by laterally projecting extensions 5 on the vertebral bodies.

For the fusion of two adjacent vertebral bodies 1 and 2, the disc is normally removed and replaced by a 3 spacers, this is not shown in the drawing. It is also advantageous, thereby limiting the possibility of movement of the adjacent vertebral bodies 1 and 2 in addition, that the extensions 5 are fixed in the area of ​​the facet joints 4 relative to each other.

This is done in the present case by an implant in the form of a clip 6 having a bridge 7 and transversely extending therefrom, parallel, coplanar arms 8, 9 comprising (Figure 3). The arms 8 and 9 are of unequal length, for example, the length of the web may be 16 mm, the length of the short arm 10 mm and the length of the long arm 18 mm. The two arms 8 and 9 are tapered at their ends.

The bracket consists of a shape memory alloy such as a nickel-titanium alloy, the other metals can be added yet, such as vanadium. This shape-memory alloys have the property that they pass on increases in temperature of a martensitic state to an austenitic state and thereby change their shape, and indeed reversible. In this case, the material properties are selected such that the transition temperature is slightly above normal body temperature, ie, above 37 ° C. A cooled clamp is thus located in the martensitic low-temperature state, a transition to the high temperature austenitic state occurs only when heated to a temperature of the clip, which is above body temperature. Such heating is carried out by the targeted heating, for example by a hot air current, by applying a hot liquid, or by a special electric heater. This has the advantage that the surgeon can insert the clip at body temperature in the body, without the transition from the martensitic to the austenitic state occurs. Only when the clip takes up the correct position, this transition can be achieved through targeted heating. Even when cooled to body temperature, the shape memory alloy is in the austenitic high temperature state because the return is due to the transformation temperature hysteresis properties of alloys well below body temperature.

For insertion of the clip 6, this is brought with the pointed ends of the two arms 8 and 9, so the side of the facet joint 4 that in each case one of the two arms can be inserted in each case an extension 5 of a vertebra 1 and 2, respectively 8 and 9 , whether by driving, either by plugging into predrilled holes. The introduction is carried out after pre-cooling of the bracket 6, that is the bracket 6 is in the low temperature martensitic state during insertion of the arms 8 and 9 so in this case have a large distance from each other. This can for example take place in that the clip corresponding to the representation of Figure 3 with a stretched web 7 and parallel extending arms 8 and 9 is present.

The arms 8, 9 of clip 6 are preferably placed so that the short arm 9 is driven into the inferior articular processes of the upper vertebral body, the longer arm 8 on the other hand in the pedicle entry point of the lower vertebral body. The lower articular process of the upper vertebra is usually thicker trained det than the medially subsequent vertebral arch, and therefore it must be ensured that the shorter arm 9 is used not too far medially, is thus safely placed in the inferior articular processes. It is quite possible here that notwithstanding 1, the plane of the bracket is inclined relative to the longitudinal axis of the spine of the illustration of FIG.

After insertion, the clip 6 is heated and thereby enters the austenitic high-temperature state, thereby a deformation in such a way that the arms 8 and 9 are closer to each other. This can be achieved in that the arms 8 and 9 are bent more strongly in the region of the connection between the arms 8 and 9 and the web 7, and thus swing against each other, it is also possible that bent into a in this deformation of the stretched web 7 even merges configuration, this also leads to a rapprochement between the two arms 8 and 9. of course, both deformations may also be present simultaneously.

As a result, the arms are thus closer together during the heating of the clip 8 and 9, while they clamp the two parts of the facet joint 4 against each other, the two facet joints between the two vertebral bodies to be fixed thereby.

In Figure 4, another preferred embodiment example is playing a clip 6 is shown, corresponding parts bear the same reference numerals.

In contrast to the bracket of Figure 3, which is bent from a round material, there is a clip 6 of Figure 4 from a flat strip, for example of a cold-rolled sheet, so that the arms 8 and 9 strip- or plate-shaped.

8, 9 run Again, the arms pointed to, in contrast to the embodiment of Figures 1 to 3 of the shorter arm 9 is split into two parallel individual arms 10, 11 adjacent to each other. Also located in the web 7, an opening 12, in the example, an insertion instrument can be used, so that the insertion of the bracket is facilitated.
