Description
Technical field
The present invention relates to a kind of medical apparatus and instruments of dental operation, is a kind of Medical oral cavity location dilator specifically.
Background technology
Operation on oral cavity, with in inspection, for ease of operation, needs patient's mouth open up into a certain degree and keep the regular hour.But some patient loses consciousness because of reasons such as anesthesia, cannot initiatively opening, need to adopt various operating theater instruments to strut the oral cavity of patient.Chinese patent 2010101762485 discloses one " integral-type initiative oral cavity mouth gag ", another Chinese patent 2010101758935 discloses one " splitting active oral cavity mouth gag ", both torsion spring is set between maxillary plate and mandibular plate, utilizes the torsion of torsion spring to make maxillary plate and mandibular plate keep the strength necessarily expanded outwardly.During use, doctor or patient pinch maxillary plate and mandibular plate is put between the upper and lower facies occlusalis dentis in patient oral cavity, and after unclamping hands, the torsion of torsion spring is by patient's oral cavity expanding.Although this oral cavity mouth gag is easy to use, and can do according to the wish of patient motion of independently remaining silent, can only as the motion exercise assistive device of patient's Restoration stage.As in operation, patient oral cavity cannot be fixed to suitable position, be unfavorable for operation technique; In addition, in operation, the unconscious action of remaining silent of patient is also likely bitten doctor or patient oneself.
Summary of the invention
The object of this invention is to provide a kind of compact conformation, easy to use, accurate positioning, safe and reliable Medical oral cavity location dilator.
For reaching above object, the technical solution adopted in the present invention is: this Medical oral cavity location dilator comprises the Lower jaw support be sleeved on lower jaw tooth, the upper jaw holder be sleeved on maxillary teeth, described Lower jaw support and upper jaw holder are the shape of a hoof, the lower surface of Lower jaw support is provided with lower alveolus, the upper surface of upper jaw holder is provided with alveolus, the two ends of described Lower jaw support are hinged with the right bar of lower support and the left bar of lower support respectively, and the two ends of described upper jaw holder are hinged with the right bar of support and the left bar of upper support respectively; The upper end of the right bar of described lower support and the lower end of the right bar of upper support are hinged on right hinge, and the upper end of the left bar of described lower support and the lower end of the left bar of upper support are hinged on left hinge, and described right hinge and left hinge are installed on axis; The outer surface of described axis is provided with external screw thread and spline, described right hinge and left hinge are all sleeved on axis by spline, described axis is equipped with nut by external thread sleeve, the nut sleeve of tubulose is sleeved on described nut slidably, the outer surface of described nut is provided with worm gear, with gap between described nut sleeve and nut, described nut sleeve runs through worm screw is installed, the polished rod section at described worm screw two ends is slidably mounted on the tube wall of nut sleeve, and the stage casing that described worm screw is positioned at nut sleeve inner chamber is engaged with described nut by worm and gear cooperation.
Beneficial effect of the present invention is: compact conformation, easy to use, accurate positioning, safe and reliable, patient oral cavity can be positioned at any angle by the auto-lock function of worm-and-wheel gear, without the need to extra locking mechanism, avoids the patient oral cavity closed danger that brings and hidden danger suddenly.

Detailed description of the invention
As shown in Figure 1, Medical oral cavity location of the present invention dilator comprises the Lower jaw support 1 be sleeved on lower jaw tooth, the upper jaw holder 2 be sleeved on maxillary teeth.As shown in Figure 4, described Lower jaw support 1 is the shape of a hoof with upper jaw holder 2, the lower surface of Lower jaw support 1 is provided with lower alveolus, the upper surface of upper jaw holder 2 is provided with alveolus 21, the two ends of described Lower jaw support 1 are hinged with the right bar of lower support 3 and the left bar 4 of lower support respectively, and the two ends of described upper jaw holder 2 are hinged with the right bar of support 5 and the left bar 6 of upper support respectively; The upper end of the right bar of described lower support 3 and the lower end of the right bar of upper support 5 are hinged on right hinge 7, and the upper end of the left bar of described lower support 4 and the lower end of the left bar of upper support 6 are hinged on left hinge 8, and described right hinge 7 and left hinge 8 are installed on axis 9.As shown in Figure 2, right hinge 7 and left hinge 8 are provided with radial through hole, axis 9 is inserted in radial through hole, the end of each support bar is sleeved on right hinge 7 or left hinge 8 by bearing-ring device, each support bar can rotate around right hinge 7 or left hinge 8, and right hinge 7 or left hinge 8 can move axially on axis 9.When right hinge 7 and left hinge 8 are mobile on axis 9 time, the distance changed between right hinge 7 and left hinge 8 can change the distance between Lower jaw support 1 and upper jaw holder 2, namely changes the degree of opening in patient oral cavity.For avoiding right hinge 7 and left hinge 8 to come off from axis 9, install end cap respectively at the two ends of axis 9, the diameter of end cap is greater than the diameter of right hinge 7 and left hinge 8 installing hole, and then can be limited between two end caps, avoids coming off.
As shown in Figure 3, the outer surface of described axis 9 is provided with external screw thread and spline, described right hinge 7 and left hinge 8 are all sleeved on axis 9 by spline, with the spline protruded in the through hole of right hinge 7 and left hinge 8, described spline is installed in spline, right hinge 7 and left hinge 8 can only be moved axially on axis 9, can not rotate.Described axis 9 is equipped with nut 10 by external thread sleeve, makes nut 10 can rotate advance on axis 9.The nut sleeve 11 of tubulose is sleeved on described nut 10 slidably, the outer surface of described nut 10 is provided with worm gear, with gap between described nut sleeve 11 and nut 10, described nut sleeve 11 runs through worm screw 12 is installed, the polished rod section at described worm screw 12 two ends is slidably mounted on the tube wall of nut sleeve 11, and the stage casing that described worm screw 12 is positioned at nut sleeve 11 inner chamber is engaged with described nut 10 by worm and gear cooperation.Nut 10 can be promoted when rotary worm 12 rotate, thus make it move on axis 9.Be sleeved on described nut 10 slidably to make nut sleeve 11, as shown in Figure 5, the both ends of the surface of nut 10 are provided with the circular draw-in groove concentric with axis 9, end cap is provided with in the both ends of the surface of nut sleeve 11, on described end cap, correspondence position is provided with the snap ring 15 of matching circular draw-in groove, and snap ring 15 is installed in circular draw-in groove.Like this, both can nut sleeve 11 be fixed on nut 10, both can be made again relatively to rotate.Nut 10 can be promoted by handle rotary worm 12 to move, the nut 10 be arranged between right hinge 7 and left hinge 8 can promote again hinge and move, thus the distance changed between right hinge 7 and left hinge 8, thus the lower height between supporting portion 1 and upper supporting portion 2 of adjustment.During use, be set on the upper and lower tooth of patient by upper jaw holder 2 and Lower jaw support 1, tooth is stuck in alveolus, is fixed by upper and lower jaw, slippage when upper jaw holder 2 and Lower jaw support 1 can be avoided to move.Be positioned at patient oral cavity with the operating side of the vertically disposed worm screw 12 of axis 9 to hit exactly, convenient operation.
