Description
Technical field
The utility model relates to the field of medical instrument technology, specifically, being a kind of bone for cervical vertebral body vancement
Slot fusion device.
Background technique
Cervical ossified posterior longitudinal ligament (OPLL) refers to that the posterior longitudinal ligament because of cervical vertebra ossify, to oppress spinal cord and mind
Through root, the feeling of limbs and the illness of dyskinesia and internal organ vegetative nerve functional disturbance are generated.
Have in the prior art about the common operative treatment of cervical ossified posterior longitudinal ligament: posterior cervical decompression technology, neck
Vertebra anterior decompression technology etc..
Posterior cervical decompression technology includes En bloc laminoplasty and laminectomy, and the advantage of posterior cervical decompression technology is:
Do not cut bone compound, and operation is comparatively safe, and pressure relief ranges are wide, and stability is destroyed less, and long segment OPLL can be handled, and can retain certain
Mobility, but existing disadvantage is: cervical curvature and ossification object size are required, K-line (-) effect is poor, C5 radiculopathy
Incidence is high, and ossification object may continue to growth and cause to oppress again, postoperative generation neck portion's pain and cervical kyphosis.
Anterior cervical decompression art includes Subtotal vertebrectomy for treatment, floating method；The advantage of anterior cervical decompression art is: cutting bone
Compound, effect of easing stress is good, and treats serious OPLL effect and be better than posterior decompression.And existing disadvantage is: difficulty is high, easily
Neurotrosis is caused, leakage of cerebrospinal incidence is high, and long segment OPLL rebuilds difficulty, and operating time is long, and amount of bleeding is big.
In order to take into account effect+posterior approach safety of preceding road technique, professor Shi Jiangang depressurizes theory in situ
Guidance issues a kind of anterior cervical vertebrae vertebral bone compound complex Forward technology (ACAF technology) is illustrated, for this is technically simple, just
Implantation lifting titanium plate, preceding road centrum is lifted outward on preceding road centrum, to avoid compressing spinal cord and nerve root.Wherein, because
The characteristics of human physiological structure, preceding road centrum are composed in free centrum, are not monoblock type, between adjacent vertebral
Gap can use traditional Invasive lumbar fusion device, and free two side seam slot of centrum is temporarily available without corresponding fusion device.Because fusion device needs
It is placed in two side seam slots, is not moved under the premise of cervical vertebra moving, and need amalgamation good, this is the difficult point of design, fusion device relationship
The success or failure entirely performed the operation, have extremely important effect.
Chinese patent literature CN201010519973.8, the applying date 20101026, patent name are as follows: a kind of adjustable ACAF
Technology-specific bone slot fusion device, including main structure and sliding latch device, main structure by separate setting upper and lower main board and
The polyester tension ligament for being coated on upper and lower main board surrounding is constituted, and bone slot, upper and lower main board are held in setting in the middle part of main structure
Two sides in the middle part of be symmetrical arranged I-shaped support universal driving shaft, support universal driving shaft upper axis and lower axle respectively through liner with it is upper and lower
Main board rotation connection, the sliding latch device are located at one end of main structure.
The angle regulating function of the Invasive lumbar fusion device of above patent document makes whole system more meet organization of human body, not only side
System placement, the support construction for more making system incorporate backbone meets body mechanics, and postoperative good fusion is also reduced
The risk factor that Neck dissection and screw fracture, pull out.But it is suitable for ACAF technology about one kind, amalgamation is good, Gu
The technical solution of definite effect is determined then without corresponding open.
In conclusion one kind is needed to be suitable for ACAF technology, amalgamation is good, the exact bone slot fusion device of fixed effect, and
It yet there are no report about this bone slot fusion device.
