DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an osteosynthesis or correction set for use in, for example, suturing and fixing a vertically cut sternum after performing a heart operation after cutting the sternum vertically.

[0002]

2. Description of the Related Art Heart surgery is performed in hundreds of thousands of cases worldwide every year. Many after skin incision,
Cut the sternum vertically, open the sternum left and right, perform heart surgery,
After the completion of the cardiac surgery, the sternum 2 cut vertically as shown in FIG.
(0 cm) at 6 to 8 places.

As shown in FIG. 2, after the heart operation is completed, the sternum 2 is pierced with a drill 3, and the stainless steel wire 1 is attached to the tip of the drill 3 and pulled out. This wire 1 has a diameter of about 0.2 mm at both ends and a diameter of 1.0 mm at the center as shown in FIG.
It is. The drill 3 is pulled out, and the wire 1 is passed through a state as shown in FIG. In order to fix the sternum 2, it is necessary to use 6 to 8 wires as shown in FIG.

As shown in FIG. 3, after passing the wire 1 through the sternum 2, the wire 1 is twisted 4 to 5 times as shown in FIG.
Cut to the extent that the length of the torsion is about 10 mm.
It is believed that this length will not untwist the wire 1. By such a twisting operation of the wire 1, the left and right sternum 2, 2 are pulled, and as shown in FIGS. 4 and 5, there is no gap between the left and right sternum. The twisted wire 1 was laid down as shown in FIG. 5, and this portion was covered with a cortical layer and a muscular layer to complete the operation. Note that the wire remains in the patient's body for a lifetime.

The above-described conventional wire twisting method is widely used all over the world. However, twisting only 6 to 8 wires for fixing the sternum requires about 15 minutes. May be disconnected,
This operation requires considerable power from the surgeon.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide an osteosynthesis or correction set which can fix a wire in a simple and instant manner without the need for a conventional twisting operation of a suturing wire. On the point.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a suture or orthodontic wire, which can be gripped without any resistance, and which is in close contact with the suture or orthodontic wire gripped by the swaging operation. The present invention relates to an osteosynthesis or correction set comprising a metal wire fixing device capable of fixing the same.

The metal wire fixing device has a slightly larger diameter hole or groove of the suturing or correcting wire, so that the suturing or correcting wire can be held without any resistance. The shape is preferably corresponding to the location of the bone or tooth to be treated, and specific examples thereof are shown in FIGS. (A-1),
(B-1) and (c-1) are perspective views, and (a)
2), (b-2), and (c-2) are cross-sectional views.

The osteosynthesis or correction set of the present invention comprises:
It is very suitable for sternal fixation of the sternum, but is not limited thereto, and has various uses such as treatment after cutting of bone, treatment of fracture, correction of bone and teeth. Although the description herein focuses on the sternum junction, the bones targeted by the present invention are not limited to the sternum, but may be any bone.

In the present invention, the relationship between the wire for suturing or straightening and the hole or groove of the metal wire fixture is such that the operation of inserting or inserting a wire into the hole or groove can be performed smoothly, The later caulking work is easier if it is not uselessly too large as compared with. Further, the cross-sectional shape of the wire, the hole, or the groove is basically circular as shown in FIG. 6, but is not limited to this, and the cross-section can have an arbitrary shape such as an ellipse, a rectangle, or a polygon.

As the wire in the present invention, a conventionally used stainless steel wire can be used as it is, but it is not limited to this, and any material that does not harm the human body or animals can be used.

The metal wire fixing tool of the present invention has a property that the wire can be firmly fixed by a simple procedure such as caulking, and any metal may be used as long as it does not harm human bodies or animals. A typical example is SU
Stainless steel such as S-306 and SUS-316 can be used.

To use the osteosynthesis set of the present invention,
For example, both ends of the wire 1 are pushed or fitted into the holes 12 or grooves 13 of the metal wire fixing tool 11, and both ends of the wire 1 are pulled by a pulling tool 14 as shown in FIG. The bones 2 and 2 are combined with each other, and the metal wire fixing tool 11 is caulked to complete the fixation of the bones. FIG. 8 illustrates another embodiment of the fixing method.

The bone correction set of the present invention can be used, for example, for correcting teeth. As shown in FIG. 9, a metal wire fixture (bracket) 11 is adhered to the teeth 8 and the orthodontic wire 1 is passed through a hole 12 (see FIG. 6) of the metal wire fixture 11 or a groove 13 (see FIG. 6), for example, after caulking around the hole 12 or groove 13 of the fixture (bracket) attached to the left end tooth 8, pull the orthodontic wire so that the tooth 8 is arranged in an appropriate shape. After that, each fixture (bracket) attached to each tooth 8 has one hole 12
The fixing procedure for correction is completed by caulking the center of the groove 13 or the groove.

EXAMPLES Example 1 (Fixation of the sternum after heart surgery) After the heart surgery was completed, a hole was made in the sternum with a drill, and a stainless wire was inserted into the hole in the sternum as shown in FIG. 7 (a). Then, both ends are passed through the hole of the metal wire fixing tool 11 and pulled by the pulling tool 14, and when the sternum is in a predetermined joint state, the metal wire fixing tool 11 is caulked to complete the suture fixing of the sternum. did. The stainless wire used at this time had a diameter of 1 mm, and the metal wire fixture 11 was SUS-3.
06, the size was 4 × 8 mm, the thickness was 1.8 mm, and the corners were rounded. Compared with the conventional method of twisting a wire, the present invention can reduce the time required for suturing, is easy to fix, and has a beautiful finish.

[0016]

(1) The osteosynthesis or correction set of the present invention is simpler in the treatment operation than the conventional method, so that the operation time can be shortened. For example, when seven wires are used to fix a sternum suture after a heart operation, the conventional method requires about 15 minutes, whereas the present invention requires about 3 minutes.
In minutes. (2) In the case of the conventional method, since the wire is twisted and fixed, the wire may be broken by twisting, and it is necessary to start over from the beginning. However, in the present invention, the wire is not broken. (3) If the conventional method in which the wire is twisted is used, the twisted portion becomes a lump like a "dango", and the portion becomes lumpy. Often this bump is palpable over the skin, which is not only very disturbing to the patient, but also sometimes causes pain. If you're an obese patient, you're not worried.
Skinny patients have no subcutaneous fat and a thin muscle layer, so the "dango" of the wire is very disturbing and often painful. On the other hand, the thing of the present invention is small and can be flattened, so that there is no sense of incongruity due to the presence of the "dango" -like material as compared with the conventional method.
