Definitions

  • the present invention relates to a bent osteotomy blade (chisel) used when performing lumbar osteotomy in microinvasive surgery for lumbar spinal canal stenosis.
  • FIG. 1 An axial cross-sectional view of a normal lumbar spinal canal is shown in FIG.
  • the lumbar spinal canal 1 is a lumen surrounded by an intervertebral joint 2, a yellow ligament 3, a vertebral arch 4, an intervertebral disc, and the like, and a spinal cord or a dural tube or a nerve root passes through the lumen.
  • Lumbar spinal canal stenosis is a disease that causes neurological symptoms in the lower limbs due to narrowing of the spinal canal due to enlargement of the facet joints and thickening of the yellow ligaments as shown in FIG.
  • Posterior decompression which is a common surgical treatment for lumbar spinal canal stenosis, is a treatment method that expands the spinal canal by partially excising the bones of the vertebral arch and intervertebral joints and also excising the yellow ligament. .
  • MED micro endoscopic spectroscopy
  • a cylindrical outer tube having a diameter of less than 2 mm is installed on the back side of the vertebral arch, and the operation is completed under the endoscope within the outer tube.
  • the spinous process and supraspinatus ligament are important as a lumbar posterior braking mechanism, these tissues can be preserved and the invasion of the surrounding muscles can be minimized.
  • the work is performed in the inner part of the cylindrical outer cylinder 5 which is a long and narrow cylinder. Therefore, the operation area is limited by the angle and position of the cylindrical outer cylinder. Since the spinous process 6 becomes an obstacle on the deployment side and the upper part of the cylindrical outer cylinder cannot be brought down to the spinous process side, the outer osteotomy on the deployment side is an angular problem, and there are many like the osteotomy line of the solid line 7. There was a problem that the decompression on the deployment side could not be sufficiently performed unless the bone was excised. If many bones are removed, many parts of the facet joints may be deleted or joints may be separated, which may increase instability.
  • the present invention has an object of facilitating osteotomy in the bending direction of the blade in a bending osteotomy blade used when performing osteotomy of the lumbar spine for microinvasive surgery for lumbar spinal canal stenosis. To do.
  • the main structure is composed of a blade portion, a handle having a gripping portion, and a hitting portion for hitting with a hammer, and the blade portion is bent with respect to the handle.
  • the hitting portion is projected from the handle so that the hitting portion extends so as to extend on an extension line opposite to the direction of the blade.
  • the point to be struck with a hammer is close to the straight line in the direction of the blade, even if the cutting edge of the osteotomy blade is not inserted into the bone, it can easily move in the direction of the blade, and the bone surface Less slipping.
  • bone can be cut at an angle from the back, and many bones and joints can be preserved by more selectively resecting the spinal canal side.
  • the main structure includes a blade portion 14, a handle 15 for gripping, and a hitting portion 16 for hitting a hammer, and the blade portion 14 is bent with respect to the handle 15.
  • the handle 15 is composed of a grip 17 which is a thickened portion for gripping by hand and a shaft 18 which is continuous with the blade portion 14.
  • the hit portion 16 is bent and continuous at the end of the handle 15 and has an arc-shaped shape with the tip of the blade portion 14 as the center point, and passes over an extension line opposite to the blade direction. It is a rigid structure with a length.
  • the main structure includes a blade portion 19, a handle 20 for gripping, and a hitting portion 21 for hitting a hammer.
  • the blade portion 19 is bent with respect to the handle 20.
  • the handle 20 is composed of a grip 22 which is a thickened portion for gripping with a hand and a shaft 23 which is continuous with the blade portion 19.
  • the hit portion 21 is a rigid structure that branches off from the lower end of the grip 22 of the handle 20 and extends opposite to the bending direction of the blade portion 19, and extends on the extension line in the direction opposite to the blade direction.
  • a hitting point 24 is attached in the vicinity.
