The mouth-opening bracket for the department of stomatology is characterized in that the upper supporting plate and the lower supporting plate are arc-shaped plates with the middle parts bent backwards.
The mouth opening support is characterized in that an upper anti-falling plate is fixedly connected to the upper surface of the upper supporting plate, and a lower anti-falling plate which corresponds to the upper anti-falling plate vertically is fixedly connected to the lower surface of the lower supporting plate.
The mouth opening bracket for the department of stomatology is characterized in that the upper anti-falling plate and the lower anti-falling plate are both arc-shaped plates with the middle parts bent forwards.
The mouth opening bracket for the department of stomatology is characterized in that the upper anti-falling plate and the lower anti-falling plate are respectively positioned at the rear middle positions of the upper supporting plate and the lower supporting plate.
The mouth-opening bracket for the department of stomatology is characterized in that through holes are respectively formed in the lower supporting plate in a left-right corresponding mode, and the through holes are communicated with the sleeve.
The mouth-opening bracket for the department of stomatology is characterized in that the inner profile of the cross section of the sleeve is non-circular, and the guide block is connected with the sleeve in an interference fit mode.
The mouth opening support for the department of stomatology is characterized in that the guide hole in the guide baffle is non-circular, and the adjusting rod is connected with the guide baffle in an interference fit manner.
The mouth-opening bracket for the department of stomatology is characterized in that the inner contour of the cross section of the sleeve is triangular or rectangular, and the guide hole in the guide baffle is triangular or rectangular.
The mouth-opening bracket for the department of stomatology is characterized in that the upper end of the guide block is provided with a chamfer.
The sleeve and the adjusting rod are arranged between the upper supporting plate and the lower supporting plate, and the distance between the upper supporting plate and the lower supporting plate can be adjusted through the sleeve and the adjusting rod. The patient can bite the upper and lower teeth on the upper support plate and the lower support plate respectively, the oral cavity of the patient can be opened by the invention, and a certain opening size can be kept. Patient's oral cavity is opened passively, and has last backup pad and bottom suspension fagging to support, compares the initiative and opens the mouth, and the muscle of patient face is difficult to fatigue, and the state of opening the mouth can be kept for a long time, is favorable to medical staff's treatment and nursing operation, improves work efficiency, and easy operation, convenient to use.
Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, fig. 2 and fig. 3, a mouth opening support for department of stomatology, including last backup pad 2 and bottom suspension fagging 9 that correspond the setting from top to bottom, go up bilateral symmetry difference fixedly connected with below backup pad 2 and adjust pole 4, adjust 4 lower extreme fixedly connected with guide block 7 of pole, bilateral symmetry difference fixedly connected with and adjust 4 corresponding sleeve 8 from top to bottom above the bottom suspension fagging 9, sleeve 8 upper end fixedly connected with guide baffle 3, the penetrating guiding hole from top to bottom has been seted up on the guide baffle 3, adjust pole 4 and pass from top to bottom the guiding hole activity, guide block 7 is movable about setting up in sleeve 8, 3 side threaded connection of guide baffle has set screw 5, the inner end top of set screw 5 is adjusting outside pole 4, it fixes a position on guide baffle 3 through set screw 5 to adjust pole 4.
The upper supporting plate 2 and the lower supporting plate 9 are arc plates with the middle bent backwards. Go up fixedly connected with on backup pad 2 anticreep board 1, fixedly connected with is corresponding lower anticreep board 10 from top to bottom with last anticreep board 1 below the lower backup pad 9. The upper anti-falling plate 1 and the lower anti-falling plate 10 are both arc plates with the middle bent forwards.
In this embodiment, the upper end of the guide block 7 is provided with a chamfer. And the upper anti-falling plate 1 and the lower anti-falling plate 10 are respectively positioned at the rear middle positions of the upper supporting plate 2 and the lower supporting plate 9. The lower supporting plate 9 is correspondingly provided with through holes 6 from top to bottom left and right, and the through holes 6 are communicated with the sleeve 8. The length of the adjusting rod 4 can be prolonged by the through hole 6, and the length of the sleeve 8 can be shortened, so that the adjustable distance between the upper supporting plate 2 and the lower supporting plate 9 is increased.
The inner profile of the cross section of the sleeve 8 is non-circular, and the guide block 7 is connected with the sleeve 8 in an interference fit manner. The guide hole on the guide baffle 3 is non-circular, and the adjusting rod 4 is connected with the guide baffle 3 in an interference fit manner. The inner contour of the cross section of the sleeve 8 is triangular or rectangular, and the guide hole on the guide baffle 3 is triangular or rectangular.
