Abstract

Provided is a bone fixation band which can be easily handled, enables to securely fasten the bone, and also to prevent the post-operative inconveniences by forming the head part as thin as possible. The band head of the bone fixation device is constituted of a plate being bent in roughly an N-letter shape. The plate comprises three through-holes arranged in the extended direction of the band. The band is passed through into the through-hole just like sawing and then is folded back to pass through again into the through-hole and fixed. A sharp and curved needle is provided at the tip of the band for easily being set around the bone to be a fixation target and also for making a hole in the bone so that the band can be easily passed through.

Claims

1. A bone fixation device used for fixing bones in a surgical operation, comprising a long strip-shaped band and a band head provided at an end part of said band, wherein said band head is constituted of a single plate having two or more through-holes arranged in an extended direction of said band.

2. The bone fixation device according to claim 1, wherein said band head is curved or bent so that said band easily passes through into said through-holes successively.

3. The bone fixation device according to claim 1, wherein said band and/or said band head are/is made of thin metal material and, preferably, of stainless steel.

4. The bone fixation device according to claim 1, wherein at least the through-hole of said band head on an attaching side of said band is in a circular shape or an oval shape.

5. The bone fixation device according to claims 1, wherein a curved needle is provided at a free end part of said band.

6. The bone fixation device according to claim 5, wherein said needle is entirely flat, has a sharply pointed tip, and at least a part of the needle is formed in a same width as that of said band or slightly wider.

7. A cutting device for cutting said band of said bone fixation device used for fixing bones in a surgical operation, comprising a long strip-shaped band and a band head provided at an end part of said band, wherein said band head is constituted of a single plate having two or more through-holes arranged in an extended direction of said band, comprising:

a guide groove for guiding said band;

a blade for cutting said band; and

a handle for handling said blade;

wherein said blade has a curved shape for cutting the tip part of said band into a round shape.

8. A band head for a bone fixation device used for fixing bones in a surgical operation, comprising a single plate which has two or more through-holes arranged in line.

9. The band head according to claim 8, wherein said plate is curved or bent so that said band easily passes through into said through-holes successively.

10. The band head according to claim 8, wherein at least one or more of the through-hole of said band head is in a circular shape or an oval shape.
