Abstract

The invention relates to a slanted slot type interbody fusion cage which is applied to spine surgery and adapted to extraperitoneal slanted interbody fusion operation. The whole interbody fusion cage is cuboid; small teeth-shaped bulges which are uniformly distributed are arranged on the upper and lower long and wide surfaces of the interbody fusion cage; a slanted threaded hole is formed in the wide and high surface with the hole and communicates with the cuboid hollow part; cancellous bone fills in the cuboid hollow part to promote interbody fusion; one surface of a hollow slanted slot body is positioned on the wide and high surface without the hole and while the other surface of the hollow slanted slot body is communicated with a hollow folding angle slot, and the formed angle ranges from 90 to 180 degrees, and both are communicated with the upper quadrate long and wide surface, rather than communicating with the lower quadrate long and wide surface; an X-ray non-transmission metal developing sheet in the fusion cage can be accurately positioned. The interbody fusion cage can solve the problem that the common interbody fusion cage cannot be adapted to new extraperitoneal slanted interbody fusion operation and can meet the clinical demand of the novel technology.

Description

A kind of oblique slot type Invasive lumbar fusion device
Technical field
The present invention relates to a kind of for the adaptive oblique slot type Invasive lumbar fusion device through the outer oblique interbody fusion of peritoneum of spinal surgery.
Background technology
Traditional lumbar spinal fusion often adopts the way of escape to carry out internal fixtion, intervertebral implantation fusion device or patient self iliac reach the object of intervertebral fusion, but this operation is generally implemented under open otch, and destroy the posterior column structure of spinal column, there is wound large, hemorrhage many, the shortcomings such as postoperative Long-term chronic pain.Although there is numerous improvement less invasive techniques method at present, implanting Invasive lumbar fusion device by the way of escape still needs to destroy posterior column structure, there is the risk of postoperative Long-term chronic pain.In recent years, a kind of oblique interbody fusion outside peritoneum is newly in the news, this new technology way of escape percutaneous inserts pedicle screw, front side is oblique implants Invasive lumbar fusion device outward through peritoneum, both the destruction to posterior column structure had been reduced, and also comparatively light to the destruction of front pillar and surrounding soft tissue, having the multiple advantages such as wound is little, painful gently, recovery is fast, few intercurrent disease, is the direction of following surgery development.But oblique implantation Invasive lumbar fusion device, if do not change the position of fusion device at intervertebral, sending down the fishbone soleplate and pedicle screw stress distribution inequality on fusion device can be caused, cause the disconnected rod of broken nail most probably, soleplate subsides, and autologous bone only inserts the mechanical property and fusion rate that cannot reach Invasive lumbar fusion device.
Summary of the invention
In order to allow this oblique interbody fusion outside peritoneum newly reach the mechanical property suitable with traditional way of escape interbody fusion and fusion rate, we devise this for the adaptive oblique slot type Invasive lumbar fusion device through the outer interbody fusion of peritoneum of spinal surgery.
The present invention is achieved by the following technical solutions:
1, oblique slot type Invasive lumbar fusion device entirety is in a cuboid, the metal developing sheet of X-ray opaque line is provided with in it, there is equally distributed dentation kick in upper and lower length and width face, centre is a cuboid hollow connection upper and lower length and width face, atresia wide high surface is connected by hollow skewed slot with the face of growing tall, and porose wide high surface has an oblique screw thread hole.
2, hollow skewed slot is made up of hollow skewed slot main body and hollow knuckle groove.
3, the oblique traveling of hollow skewed slot main body is in oblique slot type Invasive lumbar fusion device, communicate with length and width face, top, do not communicate with length and width face, below, one side is positioned on atresia wide high surface, another side communicates with hollow knuckle groove, and its central point with atresia wide high surface phase cross surface is greater than the distance of central point to the face of growing tall of itself and hollow knuckle groove phase cross surface to the distance in the face of growing tall.
4, hollow knuckle groove communicates with length and width face, top, does not communicate with length and width face, below, and one side communicates with hollow skewed slot main body, and another side communicates with the face of growing tall, and itself and hollow skewed slot main body angulation are not less than 90 degree, and are less than 180 degree.
5, oblique its axis of screw thread hole and hollow skewed slot body parallel, be positioned on porose wide high surface, is connected with cuboid is hollow.
6, metal developing sheet has three pieces, and at sustained height, three pieces of metal developing sheet lines are a triangle.
Accompanying drawing explanation
Fig. 1 oblique slot type Invasive lumbar fusion device side isometric view.
Fig. 2 oblique slot type Invasive lumbar fusion device front is seen.
In figure: 1. length and width face above; 2. length and width face below; 3. porose wide high surface; 4. atresia wide high surface; 5. to grow tall face; 6. cuboid is hollow; 7. oblique screw thread hole; 8. hollow skewed slot; 9. metal developing sheet; 10. hollow skewed slot main body; 11. hollow knuckle grooves.
Detailed description of the invention
The present invention is adaptive through the outer oblique interbody fusion of peritoneum, adopts the side endoscope passage of this Invasive lumbar fusion device adaptive to insert.When rear percutaneous cervical arc root screw insert fixing after, stung except vertebral pulp and worn upper and lower cartilage endplate by left front side scope approach.Select the Invasive lumbar fusion device of suitable size, cuboid hollow 6 fills in spongy bone, supporting apparatus holds the oblique screw thread hole 7 on porose wide high surface 3, the direction of adjustment fusion device, from atresia wide high surface 4, by the hollow skewed slot 8 of this Invasive lumbar fusion device and the barred body phase sleeve on supporting service aisle, now hollow skewed slot 8, supporting holding apparatus and supporting service aisle are parallel to each other, progressively push in intervertebral space along hollow skewed slot main body 10, now length and width face 1, top and the dentation kick on length and width face, below 2 with bone soleplate close contact, when barred body on supporting service aisle arrives hollow knuckle groove 11 place, remove the holding of supporting apparatus, that knocks Invasive lumbar fusion device with supporting apparatus is free wide high surface 3, the far-end of Invasive lumbar fusion device can be made to turn to front, by C arm X-ray machine perspective under with the metal developing sheet 9 of X-ray opaque line be with reference to confirmation Invasive lumbar fusion device position, be adjusted to and be satisfied with position, and make Invasive lumbar fusion device insert intervertebral space along hollow knuckle groove 11, the face of growing tall 5 of Invasive lumbar fusion device is knocked again with supporting apparatus, Invasive lumbar fusion device is finally made to be in intervertebral space central authorities, and it is parallel with Coronal.
