Abstract
This utility model relates to outside lumbar vertebra BAK after a kind of percutaneous, comprise hollow, rectangular shape body, it is characterized in that: hollow, rectangular shape body has bullet-shaped front end, run through along its length in the middle part of hollow, rectangular shape body and be provided with axial duct, be respectively equipped with unidirectional pawl on the upper and lower surface of hollow, rectangular shape body, the space for bone grafting is left in the outside of axial duct.The utility model has the advantages that: during the capable interbody fusion for the treatment of prolapse of lumbar intervertebral disc degenerative disorders, wound is little, goes out insufficiency of blood, without the need to destroying paraspinal muscle and ligament, to dural sac and nerve root substantially without harassing and wrecking, can to use down foramen intervertebrale lens is auxiliary, safer.
Description
Technical field
This utility model relates to a kind of lumbar interbody fusion device of Minimally Invasive Surgery, and namely outside lumbar vertebra BAK after percutaneous, for the lumbar interbody fusion Minimally Invasive Surgery that foramen intervertebrale lens assists lower percutaneous to be entered by posterolateral approach, belongs to medical instruments field.
Background technology
The degenerative disorders such as prolapse of lumbar intervertebral disc, lumbar spinal stenosis, lumbar spondylolisthesis are commonly encountered diseases and the frequently-occurring disease of orthopaedics, and according to statistics, the sickness rate of China's degenerative diseases of lumbar vertebrae reaches 15.2%, and namely about there are 200,000,000 patients in the whole nation.For the degenerative diseases of lumbar vertebrae patient with chronic low-back pain and nerve compression symptom, spinal canal decompression and spinal fusion remove the effective ways of pain and treatment unstable spine, and interbody fusion is considered to the spinal fusion techniques that is comparatively satisfied with.
Between Wicresoft's lumbar vertebra, fusion is current developing direction, but existing Minimally Invasive Surgery has some shortcomings: as auxiliary in peritoneoscope or minimal incision * Wicresoft front road lumbar surgery, easy damaged trunk and visceral nerve in art, postoperatively easily there is the complication such as retrograde ejaculation, urine dysfunction, and can not remove because of the nervous symptoms caused by the compressing of canalis spinalis rear; Pipeline assist under spinal canal decompression and the application of intervertebral fusion technology and Wicresoft's pedicle screw technique for fixing, the stripping to paraspinal muscle stop can be avoided, the damage of the other soft tissue of vertebra can be reduced, less to the damage of posterior column structure, but need tractive dural sac and nerve root in art, easily cause the damage of dural sac, nerve root and cauda equina nerve, increase the probability of dural sac, nerve root cicatricial adhesion.
Summary of the invention
The purpose of this utility model is to provide a kind of lumbar interbody fusion device of Minimally Invasive Surgery, for the lumbar interbody fusion Minimally Invasive Surgery that foramen intervertebrale lens assists lower percutaneous to be entered by posterolateral approach.
In order to achieve the above object, the technical solution of the utility model there is provided a kind of lumbar interbody fusion device of Minimally Invasive Surgery, comprise hollow, rectangular shape body, it is characterized in that: hollow, rectangular shape body has bullet-shaped front end, run through along its length in the middle part of hollow, rectangular shape body and be provided with axial duct, be respectively equipped with unidirectional pawl on the upper and lower surface of hollow, rectangular shape body, the space for bone grafting is left in the outside of axial duct.
The utility model has the advantages that: during the treatment capable interbody fusion of degenerative diseases of lumbar vertebrae, wound is little, goes out insufficiency of blood, without the need to destroying paraspinal muscle and ligament, to dural sac and nerve root substantially without harassing and wrecking, can use under foramen intervertebrale lens is auxiliary, safer.
Accompanying drawing explanation
The structural representation of outside lumbar vertebra BAK after a kind of percutaneous that Fig. 1 provides for this utility model.
Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1, the lumbar interbody fusion device of a kind of Minimally Invasive Surgery that this utility model provides, comprises hollow, rectangular shape body.Hollow, rectangular shape body is polyether-ether-ketone material, and it has bullet-shaped front end 1.In hollow, rectangular shape body, there is an axial duct 2, can seal wire be passed, convenient implantation.There is unidirectional tooth 3 on the upper and lower surface of hollow, rectangular shape body, the frictional force with surface of bone can be increased by unidirectional tooth 3, play anti-skidding effect, and can only enter and can not go out.The space 4 that the outside of axial duct 2 is stayed is for bone grafting.
According to size and the intervertebral space average height of Chinese adult lumbar vertebra soleplate, fusion device length is 28mm-34mm, and be highly six kinds of specification 7mm-12mm, width is 10mm.
