Abstract
The invention relates to a working channel adapted to a slanted slot type interbody fusion cage applicable to spine surgery and adapted to extraperitoneal slanted interbody fusion operation. The working channel comprises a channel plate and a bar type channel plate which can form a channel that is roughly in a shape of hollow cuboid; the channel plate and the bar type channel plate are composed of main baffles, secondary baffles at two sides, and arc-shaped baffle plates; the bar type channel plate further comprises a slanted slot bar; the arc-shaped baffles extend from the secondary baffles and are outwards expanded like arc shape; a slanted slot bar is positioned below the part in which the arc-shaped baffle plates are connected with the secondary baffle plates, and close to the secondary baffle at one side without the arc-shaped baffle; the secondary baffles, the arc-shaped baffles and the slanted slot bar are respectively vertical to the main baffle. The working channel solves the problem that the common working channel cannot be adapted to the novel slanted slot type interbody fusion cage of the interbody fusion operation and can meet the clinical demand of the novel technology.
Description
Technical field
The present invention relates to a kind of service aisle for spinal surgery, the adaptive oblique slot type Invasive lumbar fusion device through the outer oblique interbody fusion of peritoneum.
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 oblique slot type Invasive lumbar fusion device, service aisle in the past obliquely can only be placed in intervertebral space, and this can cause sending down the fishbone soleplate and pedicle screw stress distribution on fusion device uneven, causes the disconnected rod of broken nail most probably, soleplate subsides.
Summary of the invention
In order to allow this new oblique slot type Invasive lumbar fusion device finally be in intervertebral space central authorities, and parallel with Coronal, and we devise this service aisle for the adaptive oblique slot type Invasive lumbar fusion device through the outer oblique interbody fusion of peritoneum of spinal surgery.
The present invention is achieved by the following technical solutions:
1, service aisle is by dust piece be with excellent dust piece to form, the material that employing has good biological mechanical property, applicable medical science uses is made, and both draw close the passage of formation one substantially in hollow cuboid mutually by the secondary baffle plate of both sides and the curved baffle of bottom, side.
2, dust piece is made up of the secondary baffle plate of master shield, both sides and the curved baffle of bottom, side, and curved baffle is the continuity of secondary baffle plate, outside curved expansion, and secondary baffle plate and curved baffle are mutually vertical with master shield respectively.
3, with excellent dust piece by the secondary baffle plate of master shield, both sides, the curved baffle of bottom, side and skewed slot bar construction, curved baffle is the continuity of secondary baffle plate, outside curved expansion, skewed slot rod is positioned at the below being in curved baffle and secondary baffle plate junction, and near the secondary baffle plate without curved baffle side, secondary baffle plate, curved baffle and skewed slot rod are mutually vertical with master shield respectively.

In figure: 1. master shield; 2. secondary baffle plate; 3. curved baffle; 4. skewed slot rod.
Detailed description of the invention
The adaptive oblique slot type Invasive lumbar fusion device through the outer oblique interbody fusion of peritoneum of the present invention, when rear percutaneous cervical arc root screw insert fixing after, skin incision is done in left front side, chorista is to the front left side of subject disk, this service aisle is mounted on supporting rigid staybolt opening apparatus, band rod dust piece is made to be positioned at top, dust piece is positioned at below, now both master shield 1, secondary baffle plate 2 and curved baffle 3 draw close formation one hollow cuboid service aisle mutually, and curved baffle 3 is positioned at the dead astern of this service aisle.Select the supporting oblique slot type Invasive lumbar fusion device of suitable size, slightly deflect this Invasive lumbar fusion device, by its hollow skewed slot and the skewed slot rod 4 phase sleeves on this service aisle, hollow skewed slot now on supporting fusion device parallels with service aisle, fusion device is progressively pushed in intervertebral space, when the skewed slot rod 4 on this service aisle arrives the hollow knuckle groove place of supporting fusion device, Invasive lumbar fusion device is knocked with supporting apparatus, make fusion device with skewed slot rod 4 for axle rotates, and arcuately baffle plate 3 turns over and does not touch with it, when fusion device is close to the position parallel with Coronal, 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.
