Description
Technical field
The present invention relates to a kind of cervical bone plate systems, right after preceding road discectomy or Subtotal vertebrectomy operation
Preceding road cervical vertebra carries out methods of internal fixation treatment, belongs to the field of medical instrument technology.
Background technique
With the arrival in intelligent epoch, people tend to bow using electronic products such as mobile phones, in addition sleeping posture and day
The reasons such as normal living habit is bad and working method changes, cause cervical vertebra to be chronically at a tired state, so as to cause
The generation of cervical spondylosis.It has been reported that in recent years, cervical vertebra disease incidence is in high state, and is intended to rejuvenation, and blueness is few
The cervical vertebra disease incidence in year has reached 10% or more.
The medically treatment main operation method of cervical spondylosis is anterior cervical decompression fusion at present, and anterior cervical decompression is melted
Art is closed after the 50's of 20th century propose, is just considered as treating the goldstandard of cervical spondylosis, research shows that the art formula uses
Fixation is the better method for stablizing cervical vertebra in anterior cervical operation in anterior plate fixation, it is by anterior decompression (interverbebral disc
Excision or Subtotal vertebrectomy), after self bone implant, then in anterior margin of vertebral body steel plate and screw carry out it is fixed, to obtain surely
Determine cervical vertebra, fixed plant bone mass promotes the fusion of bone graft area, restores the mesh of normal intervertebral height, physiological camber and Spinal volume
's.
By a large amount of medicine cases and academic research, preceding road bone grafting decompression and fusion achieves rapid progress, but there are still
It is insufficient, one of principal element is internal fixation apparatus structure problem, select it is improper will lead to plant bone mass fall off, postoperative presence
The complication such as neighbouring section retrogression pathological changes and dysphagia.The anterior cervical vertebrae fixed system of clinical use at present, is mainly asked
Topic concentrates on that bone plate thickness is thick, rigidity is big, and precession angle is not easy to adjust and lock, precession mechanism is ineffective.
Summary of the invention
It is an object of that present invention to provide a kind of cervical bone plate systems, and bone plate designs are light and handy, and thickness is only 1.8mm, maximum limit
Degree reduces the appearance of the complication such as postoperative esophagus；Be previously provided with and rotate the cover on bone plate, can any direction quickly rotate, operation letter
It is single, fixed reliable；Screw fixed range has adjustability, convenient for bone screws precession in operation while adjusting bone screws precession side
To；Strip slot is opened up in the middle part of bone plate, meropodium screw can slide along strip slot and fix centrum, adjust convenience, shorten hand
The art time.
The present invention solve the above problems used by technical solution be: a kind of cervical bone plate system, the system include bone plate,
Pipe nipple screw and meropodium screw, the bone plate designs are light and handy, and thickness is only 1.8mm, and it is concurrent to reduce postoperative esophagus etc. to greatest extent
The appearance of disease is previously provided on bone plate and rotates the cover, can any direction quickly rotate, cover screw tail portion, prevent screw from exiting,
Strip slot is opened up in the middle part of bone plate, meropodium screw can slide along strip slot and fix centrum.The pipe nipple screw and meropodium
Screw all may pass through the fixed cervical vertebral body of bone plate holes diameter, have the function that centrum is fixed and stablized to immediate postoperative.
Particularly, bone plate 170 ° of sagittal plane pre-bending, 30 ° of cross section pre-bending, can reduce hand according to Human Physiology curvature pre-bending
Art regulating time.
Particularly, the pipe nipple screw is the angle adjustable screw of diameter 3.5 and diameter 3.75, and meropodium screw is diameter
4.0 and diameter 4.5 angle adjustable screw.
Particularly, the meropodium screw maximum diameter is greater than strip grooves, and internal diameter is less than strip grooves, can prevent screw from exiting.
Particularly, the screw axis of the pipe nipple screw and meropodium screw in bone plate sagittal plane adjustable extent up to 17 °,
Bone plate plane of structure angle adjustable range is up to 15 °.
Particularly, the internal diameter of the pipe nipple screw and meropodium screw uses twin-core pattern, and screw distal end uses cylindrical inner core,
Proximal end uses circular cone inner core.
It is rotated the cover compared with the prior art, the present invention has the following beneficial effects: being previously provided on 1, bone plate, it can be any
Direction quickly rotates, easy to operate, fixed reliable, and strip slot is opened up in the middle part of bone plate, and meropodium screw can be sliding along strip slot
Centrum is moved and fixed, convenience is adjusted, shortens operating time.2, the thickness of bone plate and plate strength are closely related, cervical bone plate root
It is designed according to the anatomic form of normal vertebral body, and bone plate effectively reduces the stimulation to esophagus with a thickness of 1.8mm, and can reduce
Bone plate rigidity has good structural strength.3, pipe nipple screw and meropodium screw fixed range have adjustability, convenient in operation
Bone screws precession adjusts bone screws precession direction simultaneously, and the angular range of screw is wide, enhances its adaptability.4, pipe nipple screw
Twin-core pattern is used with the internal diameter of meropodium screw, cylindrical pattern can provide the powerful holding power of screw, screw is avoided to exit, circle
Conical profile can provide the powerful load bearing capacity of screw, disperse and reduce stress, strengthen screw fatigue crack-resistant characteristic.
