Description
Technical field
The present invention relates to a kind of department of stomatology and the medicine equipment of oral maxillofacial surgery, specifically a kind of self-locking doctor
Use opener.
Background technology
There are two projections the ramus of mandible end of mandibular, 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 heavy burden area in joint；Condyle of mandible is jaw bones
Zhe Haofa areas can be direct fracture caused by direct strike condyle teat or mandibular chin portion or body portion by beating
Hit and caused by indirect fracture, clinically easily 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.Because condyloid process is the important component of remporomandibular joint, there is special physiological function, when condyle is dashed forward
After fracture, temporomandibular joint certainly will be influenceed, influences meshing functionss, and have substantially to children's mandibular and growing for face
Influence.At present, the treatment of fracture of condylar process is broadly divided into two major classes, 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 in the presence of 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 exposed fracture site, but use maxillary and mandibular teeth row put Arch bar splint, early contact grind one's teeth in sleep on place 2 ~ 3mm
Valve rubber, by intermaxillary traction, be scheduled on central occlusion position, the mandibular ramus for making to move up moves down, the bone stump of part on ascending branch
Recover therewith, be fixed on normal position, allow the condyle of fracture is prominent to be healed with ascending branch on this position, complete bone again and connect
Connect.Chinese patent 2012100319709 discloses one kind《Mandibular condyle fracture reduction dilator》, have and intersect 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, reaches and struts lower jaw and zygomatic arch, the purpose for appearing joint space, facilitating operation technique.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 operation technique 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 inwall, it is inconvenient for operation；In addition, lever control strength is difficult to grasp, careless slightly supporting portion is easily bent deformation；
Further, the angle in upper supporting portion and lower supporting portion is fixed, it is impossible to adapts to the individual difference of patient, it is accurate to influence to strut
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 operation technique, but it is existing
There is the universal volume of oral cavity spreader larger, there is larger handle to stay in outside patient oral cavity after strutting, psychological burden is caused to patient,
Also it is not easy to further operation technique simultaneously；Lack necessary locking mechanism, the machinery strutted easily loosens.
The content of the invention
It is an object of the invention to provide it is a kind of it is compact-sized, easy to use, adjustable range is big, reasonable stress, is suitable for not
With the self-locking medical mouth gag of individual difference.
To achieve the above objectives, the technical solution adopted in the present invention is：The self-locking medical mouth gag includes and human body
The identical upper supporting portion of lower supporting portion, zygomatic arch corresponding with human body upper jaw incisura corresponding to mandibular notch, the lower supporting portion
Upper surface is provided with slide bar groove, and the both ends of slide bar groove are respectively arranged with axle bed and transmission case, passed through between the axle bed and transmission case
Bearing is provided with slide bar；The stage casing of slide bar between axle bed and transmission case carries external screw thread, and is coordinated by screw thread and be set with
There is sliding block, the sliding block is slidably installed in slide bar groove, and the upper end of sliding block is hinged on the lower end of support bar；The upper supporting
The lower end in portion is provided with strip groove, and multiple axis holes are provided with the groove, and the upper end of support bar is arranged on axle by rotating shaft
Kong Zhong；The drive mechanism of driving slider rotation is provided with the transmission case.
The slide bar has two side by side and to be arranged in parallel, and a sliding block, the end position of two slide bars are respectively provided with every slide bar
Engaged in transmission case and by travelling gear, the worm screw set perpendicular to slide bar be provided with by bearing in the transmission case,
Any one in two slide bars by worm gear and worm engaging, the end of worm screw is provided with the mounting hole for being used for connecting handle.
The beneficial effects of the present invention are：It is compact-sized, it is entirely located in patient's mouth during use, easy to use, patient
Painful small, no psychological burden, using worm and gear drive mechanism, any position can be automatically locked at, reasonable stress, in use not
Mechanically deform or situation about fractureing easily occurs, the amplitude strutted, the scope of application can be adjusted flexibly according to Different Individual difference
Extensively.
