Description
Technical field
The utility model relates to medical auxiliary apparatus, in particular to one kind for difficult multiple through patient throat pharynx posterior approach treatment
The fixed plate of type atlantoaxial dislocation.
Background technique
Extensive region caused by atlantoaxial dislocation refers to because of factors such as congenital malformation, wound, regression, tumour, infection inflammation and operations
Vertebra (cervical vertebra first segment) and dentata (the second section of cervical vertebra) facies articularis ossium lose normal relationship in a mutual action, and joint function disturbance occurs very
To the pathological change of pressuring nerve.
Atlantoaxial dislocation is a kind of pathological change, since dislocation of atlas can be such that vertebral artery stroke is more bent or cervical vertebra stretching and beading
Activity is impacted, or even partially or completely vertebral artery occlusion occurs, and makes Vertebrobasal ischemic, oblongata and spinal cord occurs
Blood supply disorder.And atlantoaxial dislocation may slightly hurt because of incidence or whiplash due to oppresses upper neck marrow, patient can be unexpected
There is hard paralysis, in addition breathing myoparalysis and it is dead, need to timely diagnoses and treatment.
Therefore, the treatment main purpose of atlantoaxial dislocation is to release spinal compression, stablizes cervical vertebra joint, keeps atlas and pivot
The normal relationship in a mutual action in vertebral joint face prevents from dislocating again.Conservative therapy and two kinds of operative treatment are clinically generally taken now
Mode:
One, conservative therapy, for spontaneous atlanto-axial dislocation, after feasible jaw pillow is drawn to reset stabilization, doing one includes head
The gypsum of neck chest.
Two, operative treatment, of long duration for dislocating, cdontoid process heal fixation at displacement, through the irreducible difficulty of traction
Replica atlantoaxial dislocation, then take operative treatment.According to the different type of patient's atlantoaxial dislocation using correlation method to extensive region pivot
Vertebra is loosened after reset, treats Irreducible Atlanto-axial Dislocation Via Trans-oropharyngeal Approach by posterior Pedicle screw.
In clinical practice, difficult replica atlantoaxial dislocation modus operandi by approach position classify, at present there are two types of:
The first is transoral approach, does notch from oral cavity, to surrounding's contracture soft tissue of atlantoaxial dislocation, scar, bone
After equal excisions of going to live in the household of one's in-laws on getting married are loosened, resetted, then titanium plate transoral approach is put into fixation.Since oral bacteria is more, while postoperative shield
Reason is difficult, therefore the approach surgical infection rate is high, and risk is big.Since oral bacteria is more, while postoperative care is difficult, therefore by this
The infection rate after abortion operation of approach operative treatment is high, and risk is big.
Second is performed the operation through High retropharyngeal approach (swallowing posterior approach through throat), and patient takes dorsal position, from throat portion
Notch is done, loosen (excision cicatricial tissue, contracture tissue, spur etc. influence the structure resetted) of atlas and axis is carried out, due to mesh
The preceding titanium plate without the suitable approach is fixed, and postoperative atlas and axis can be unstable, therefore also needs to carry out Posterior fixation, i.e., will
Patient is adjusted to prone position, does notch again in nape corresponding position, separation subcutaneous tissue, muscle carry out atlas and axis pedicle of vertebral arch screw
Nail is fixed.Such operative treatment mode needs two operations, greatly increases operating time, blood loss volume during the operation and operation wound face, prolongs
Long post-operative recovery time seriously increases the financial burden of patient.
Summary of the invention
The purpose of this utility model seeks to overcome defect of the existing technology, and operation complexity can be simplified by providing one kind
Degree shortens the patient postoperative rehabilitation time, effectively prevent treating for swallowing posterior approach through patient throat for atlas and axis Redislocation
The fixed plate of difficult replica atlantoaxial dislocation.
To achieve the above object, for treating difficult replica extensive region pivot through patient throat pharynx posterior approach designed by the utility model
The fixed plate of vertebra dislocation, the fixed plate sheet including patient's atlas and the setting of dentata joint outer profile can be fitted in working condition
Body, the fixed plate ontology include upper end clamping part, middle part fixed plate and lower end connecting plate；The upper end clamping part is symmetrical cloth
A pair of of bone folder in patient's anterior arch of atlas portion two sides is set, the fixed board ends in the middle part are provided with fixing threaded hole, the fixed spiral shell
Atlas positioning screw matched with its is provided in hole, the middle part fixed plate passes through the atlas positioning across its both ends fixing threaded hole
Screw is connected and fixed with patient's lateral mass of atlas；Several connecting screw holes are provided on the lower end connecting plate, in the connecting screw hole
Be provided with dentata positioning screw matched with its, the lower end connecting plate pass through dentata positioning screw across connecting screw hole thereon with
Patient's dentata ontology is connected and fixed.
Preferably, the fixing threaded hole of the fixed board ends in the middle part is kidney-shaped screw hole.In this way, can be in order to performing the operation
The middle fixation position according to patient's actual conditions adjusting screw.
Preferably, the pair of bone folder is that V-type bone presss from both sides, and the atlas for being clamped in patient's anterior arch of atlas portion two sides is thick
Spend direction.In this way, it is improper relatively movable to prevent the facies articularis ossium of atlas and dentata from occurring.
Preferably, it there are three the connecting screw hole settings on the lower end connecting plate, arranges in a triangle.In this way,
The effect that is located by connecting of fixed plate ontology can be advanced optimized, the good pairing of the facies articularis ossium of atlas and dentata is kept to close
System.
Preferably, the fixed plate ontology is titanium alloy fixed plate.In this way, can guarantee the same of fixed effect
When, there is certain toughness, and since titanium plate fixed plate is from heavy and light, reduce the influence to patient's normal life.
Preferably, the pair of bone folder inside is provided with limited slip block.
Utility model has the advantages that designed is de- for treating difficult replica atlas and axis through patient throat pharynx posterior approach
The fixed plate of position avoids that nursing difficulty existing for existing modus operandi, infection rate after abortion operation are high, operation link is complicated, patient is postoperative
The problems such as rehabilitation duration is long has significantly simplified operation complexity and has avoided second operation, reduces patient's intraoperative blood loss, shortens
The patient postoperative rehabilitation time prevents atlas and axis Redislocation, and the good pairing of the facies articularis ossium of atlas and dentata is effectively kept to close
System.
