Description
Technical field
The present invention relates to a kind of medical apparatus and instruments of oral maxillofacial surgery, specifically a kind of Maxillofacial surgery apparatus.
Background technology
There are two projections the ramus of mandible end of mandibular bone, and the condyle that is referred to as being located behind is dashed forward, the lower jaw that it is expanded by upper end
Neck of mandible composition below head and head.Condyle of mandible ovalize, inside and outside path length, anteroposterior diameter are short.Side is seen, and has a horizontal ridge to incite somebody to action
The prominent top of condyle is divided into former and later two inclined-planes.Front bevel is little, is functional surfaces, is the heavy burden area in joint；Condyle of mandible is jaw bones
Zhe Haofa areas, can directly hit the direct fracture that causes of condyle teat, or mandibular bone chin portion or body portion is subject to beat
The indirect fracture hit and cause, clinically easily fails to pinpoint a disease in diagnosis.Condyle of mandible is the most weak position of mandibular bone, thus is mandibular bone
The predilection site of fracture.As condyloid process is the important component part of remporomandibular joint, with special physiological function, when condyle is dashed forward
After fracture, temporomandibular joint certainly will be affected, affect meshing functionss, and the growth promoter to child's mandibular bone and face to have substantially
Impact.At present, the treatment of fracture of condylar process is broadly divided into two big class, and a kind of is the No operation using intermaxillary traction replacement and fixation
Treatment, i.e. expectant treatment, another kind are the operative treatments of the lower replacement and fixation of surgical incision direct-view.For many years, who is excellent for two methods
Who is bad to have some disputes, but from the point of view of total situation, expectant treatment is always the main flow of Treatment of Condylar Fractures.Expectant treatment is not
Operate exposure fracture site, but puts Arch bar splint using maxillary and mandibular teeth row, on the grinding one's teeth in sleep of early contact places 2 ~ 3mm
Valve rubber, by intermaxillary traction, be scheduled on central occlusion position, move down the mandibular ramus of shifting, the bone stump of part on ascending branch
Recover therewith, be fixed on normal position, make the condyle of fracture prominent and ascending branch heal on this position, complete again bone and connect
Connect.Chinese patent 2012100319709 discloses one kind《Mandibular condyle fracture reduction dilator》, connect with hinge is intersected
Two clamp handles, the front end of two clamp handles is supporting portion, and its rear end is grip part, by hinge when grip part exerts a force
Leverage struts supporting portion, reaches and struts lower jaw with zygomatic arch, the purpose for appearing joint space, facilitating operation technique.But this
Plant dilator volume larger, inconvenient operation, in operation process, front end is located in patient's mouth, and rear end is located at oral external, harm
Hinder operation technique and patient is more painful；Supporting portion is in the same plane with grip part, and patient is close in supporting portion in use
Side cheek inwall, inconvenient operation；In addition, lever control strength is difficult to grasp, careless slightly supporting portion is easily bent deformation；
Further, upper supporting portion is fixed with the angle in lower supporting portion, it is impossible to adapt to the individual variation of patient, it is accurate that impact is strutted
Property.
The content of the invention
It is an object of the invention to provide a kind of compact conformation, the painful little, reasonable stress of easy to use, patient, being suitable for not
With the Maxillofacial surgery apparatus of individual variation.
For reaching object above, the technical solution adopted in the present invention is：The Maxillofacial surgery apparatus includes and human body lower jaw
The upper supporting portion that the corresponding lower supporting portion of incisura zygomatic arch corresponding with human body sigmoid notch coincide, the two ends in the lower supporting portion
Lower support front bar and lower support rear bar is respectively articulated with, the two ends in the upper supporting portion have been respectively articulated with support front bar and upper support rear bar；
It is described it is lower support front bar upper end with it is upper support front bar lower end be hinged on front hinge, it is described it is lower support rear bar upper end and upper support rear bar
Lower end be hinged on rear hinge, the front hinge and rear hinge are installed on axis.
The stage casing of the axis is provided with external screw thread, front hinge and rear hinge at least one by thread set in axis
On.
The outer surface of axis is provided with external screw thread and spline, during the front hinge and rear hinge are sleeved on by spline
On axle, nut is equipped with by external thread sleeve on the axis, the nut sleeve of tubulose is slidably sleeved on the nut, described
The outer surface of nut is provided with worm gear, carries gap between the nut sleeve and nut, runs through being provided with worm screw in the nut sleeve,
The light bar segment at the worm screw two ends is slidably mounted on the tube wall of nut sleeve, and the worm screw is located at the stage casing of nut sleeve inner chamber and passes through
Worm and gear cooperation is engaged with the nut.
The upper supporting portion is convex circular arc, and the lower supporting portion is recessed circular arc, lower supporting portion front end
A boss is arranged below.
The beneficial effects of the present invention is：Compact conformation, is entirely located in during use in patient's mouth, easy to use, patient
Pain is little, using screw rod or worm and gear driving structure, reasonable stress, is less likely to occur mechanically deform or fractures in use
Situation, the angle in upper and lower supporting portion and shape can be suitable for Different Individual difference according to stressing conditions adjust automatically.
