Description
Technical field
The present invention relates to a kind of department of stomatology and the medical instrument of oral maxillofacial surgery, specifically a kind of skeleton is self-locking
Formula medical mouth gag.
Background technique
The ramus of mandible end of mandibular is there are two protrusion, 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 is oval, inside and outside path length, and anteroposterior diameter is short.Side is seen, and has a horizontal ridge will
The prominent top of condyle is divided into former and later two inclined-planes.Front bevel is small, is functional surfaces, is the weight bearing area in joint；Condyle of mandible is jaw bones
The area Zhe Haofa can be direct fracture caused by directly strike condyle protrusion, be also possible to mandibular chin portion or body portion by beating
Hit and caused by indirect fracture, be clinically easy to fail to pinpoint a disease in diagnosis.Condyle of mandible is the most weak position of mandibular, thus is mandibular
The predilection site of fracture.Since condyloid process is the important component of remporomandibular joint, there is special physiological function, when condyle is prominent
After fracture, temporomandibular joint certainly will be influenced, influences meshing functionss, and have obviously to the growth and development of children's mandibular and face
Influence.Currently, the treatment of fracture of condylar process is broadly divided into two major classes, one is the No operations using intermaxillary traction replacement and fixation
Treatment, i.e. conservative therapy, another kind are the operative treatments that surgical incision looks at lower replacement and fixation straight.For many years, who is excellent for two methods
Who is bad, and there are some disputes, but from the point of view of total situation, conservative therapy is always the mainstream of Treatment of Condylar Fractures.Conservative therapy is not
Operate exposed fracture site, but maxillary and mandibular teeth column is used to put Arch bar splint, in the 2 ~ 3mm of upper placement that grinds one's teeth in sleep early contacted
Valve rubber be scheduled on central occlusion position by intermaxillary traction, move down the mandibular ramus moved up, the bone stump of part on ascending branch
Restore therewith, be fixed on normal position, allow the condyle of fracture is prominent to heal on this position with ascending branch, completes bone again and connect
It connects.Chinese patent 2012100319709 discloses a kind of " Mandibular condyle fracture reduction dilator ", has and intersects hinge connection
Two clamp handles, the front ends of two clamp handles is supporting portion, and its rear end is grip part, and grip part passes through hinge when force
Leverage struts supporting portion, achievees the purpose that strut lower jaw and zygomatic arch, appears joint space, facilitates surgical procedure.But this
Kind dilator volume is larger, and inconvenient for operation, front end is located in patient's mouth in surgical procedure, and rear end is located at oral external, harm
Hinder surgical procedure and patient is more painful；Supporting portion and grip part are in the same plane, and patient is close in supporting portion in use
Side cheek inner wall, it is inconvenient for operation；In addition, lever control strength is difficult to grasp, careless slightly supporting portion is easily bent deformation；
In addition, the angle in upper supporting portion and lower supporting portion be it is fixed, do not adapt to the individual difference of patient, it is distracted accurate to influence
Property.In addition, being also frequently necessary to passively strut patient's mouth using machinery in the operation on oral cavity such as dentistry, facilitate surgical procedure, but existing
There is the universal volume of oral cavity spreader larger, there is biggish handle to stay in outside patient oral cavity after strutting, causes psychological burden to patient,
It is also not easy to further surgical procedure simultaneously；Lack necessary locking mechanism, distracted mechanical easy loosening.
Summary of the invention
The object of the present invention is to provide a kind of compact-sized, easy to use, adjustable ranges greatly, reasonable stress, is suitable for not
With the skeleton self-locking medical mouth gag of individual difference.
To achieve the above objectives, the technical scheme adopted by the invention is that: the skeleton self-locking medical mouth gag include with
The identical upper supporting portion of the corresponding lower supporting portion of human body mandibular notch, zygomatic arch corresponding with human body upper jaw incisura, the lower supporting
The upper surface in portion is equipped with slide bar slot, and the both ends of slide bar slot are respectively arranged with axle bed and transmission case, between the axle bed and transmission case
Slide bar is installed by bearing；The middle section of slide bar between axle bed and transmission case has external screw thread, and by being threadedly engaged
It is set with sliding block, the sliding block is slidably installed in slide bar slot, and the upper end of sliding block is hinged on the lower end of support rod；On described
It is provided with strip groove below supporting portion, frame board is embedded in the groove, the frame board is curved plate-like structure, bone
The lower surface of frame plate is fixedly connected with multiple links, and the upper end of support rod is mounted in link by shaft；It is set in the transmission case
The driving mechanism for thering is driving slider to rotate.The slide bar has side by side and two disposed in parallel, and it is sliding that one is respectively provided on every slide bar
Block, the end of two slide bars are located in transmission case and are engaged by transmission gear, be equipped with vertically in the transmission case by bearing
Any one in the worm screw of slide bar setting, two slide bars is engaged by worm gear with worm screw, and the end of worm screw is equipped with for connecting
The mounting hole of handle.
The beneficial effects of the present invention are: compact-sized, when use, is entirely located in patient's mouth, easy to use, patient
Painful small, no psychological burden can be automatically locked at any position using worm and gear driving mechanism, reasonable stress, in use not
Distracted amplitude, the scope of application can be adjusted flexibly in the case where being easy to happen mechanically deform or fractureing according to Different Individual difference
Extensively.
