In a further technical scheme, the length of the first support pad and the second support pad is 2cm, and the arc length of the cambered surface on the first support pad and the second support pad is 1 cm.

The proper length can ensure that the support pad can be used for supporting the lip and buccal mucosa parts and supporting the upper and lower jaw teeth, and can not shield the visual field and influence the implementation of clinical operation in the orthodontic treatment process of the stomatologist.

In a further technical scheme, the surfaces of the first supporting pad and the second supporting pad are covered with a layer of spongy cushion.

The spongy cushion arranged on the surface of the supporting cushion can increase the comfort of a patient when in use, and also increases the surface roughness, so that the supporting cushion is not easy to slip in the use process.

In a further technical scheme, the distraction degree adjuster comprises a hollow rod and a threaded rod, one end of the threaded rod is sleeved in the hollow rod, a nut is sleeved on the threaded rod, a convex ring is sleeved on the hollow rod, and a groove matched with the convex ring is formed in the inner wall of the nut; the one end that the threaded rod stretches out hollow rod is rotatable articulated with the second vaulting pole, the one end that the threaded rod was kept away from to hollow rod is rotatable articulated with first vaulting pole.

The design of bulge loop and recess has injectd the axial displacement of nut for the nut can rotate and can not drop, and the degree of opening that props that two vaulting poles can be adjusted to the articulated design of sliding can make the degree of opening regulator that props.

The utility model has the advantages that:

1. has the advantages of simple structure, easy operation and wide application, and can solve the problem that the oral cavity and lips of patients in all ages are different in size and are difficult to be completely matched with the auxiliary appliance.

2. The cambered surface design increases the stability and the comfort of the patient in the use process, and the appearance is more beautiful.

3. The proper length can ensure that the support pad can be used for supporting the lip and buccal mucosa parts and supporting the upper and lower jaw teeth, and can not shield the visual field and influence the implementation of clinical operation in the orthodontic treatment process of an orthodontist.

4. The spongy cushion arranged on the surface of the supporting cushion can increase the comfort of a patient when in use, and also increases the surface roughness, so that the supporting cushion is not easy to slip in the use process.

5. The design of bulge loop and recess has injectd the axial displacement of nut for the nut can rotate and can not drop, and the degree of opening that props that two vaulting poles can be adjusted to the articulated design of sliding can make the degree of opening regulator that props.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

Example (b):

as shown in fig. 1, an oral cavity distraction device for orthodontic clinical use comprises a first stay bar 10 and a second stay bar 20, wherein one end of the first stay bar 10 and one end of the second stay bar 20 are respectively rotatably connected with a first bracing pad 30 and a second bracing pad 40, the other end of the first stay bar 10 and the other end of the second stay bar 20 are hinged, and a distraction degree adjuster 50 is arranged between the first stay bar 10 and the second stay bar 20.

The working principle of the scheme is as follows:

when a patient needs open mouth treatment, such as invisible correction of a lingual metal bracket, the position of the support pad is adjusted, the first support pad 30 and the second support pad 40 are respectively supported at the occlusal surface of the upper tooth and the lower tooth, and the distraction degree adjuster 50 is adjusted to ensure that the distraction degree is in a proper size; when the patient does not need open mouth treatment, such as ordinary metal bracket correction, the position of the support pad is adjusted, the first support pad 30 and the second support pad 40 are respectively padded at the left and right mouth corners of the oral cavity, and the opening degree adjuster 50 is adjusted to ensure that the opening degree is in a proper size.

In another embodiment, the first and

second stretcher pads

30 and 40 are rectangular, and the sides of the first and

second stretcher pads

30 and 40 away from the first and

second stretchers

10 and 20 are both curved surfaces.

In another embodiment, the first and

second gussets

30 and 40 are 2cm in length, and the arc length of the curved surface on the first and

second gussets

30 and 40 is 1 cm.

In another embodiment, as shown in FIG. 3, the first and

second bolsters

30, 40 are each covered on their surface by a layer of foam pad 31.

The spongy cushion 31 arranged on the surface of the supporting cushion can increase the comfort of a patient when in use, and also increases the surface roughness, so that the supporting cushion is not easy to slip in the use process.

In another embodiment, as shown in fig. 2, the distraction adjuster 50 includes a hollow rod 51 and a threaded rod 55 with one end sleeved in the hollow rod 51, the threaded rod 55 is sleeved with a nut 54, the hollow rod 51 is sleeved with a convex ring 52, and the inner wall of the nut 54 is provided with a groove 53 matched with the convex ring 52; one end of the threaded rod 55 extending out of the hollow rod 51 is rotatably hinged with the second support rod 20, and one end of the hollow rod 51 far away from the threaded rod 55 is rotatably hinged with the first support rod.

The design of the convex ring 52 and the groove 53 limits the axial displacement of the nut 54, so that the nut 54 can rotate without falling off, and the sliding hinge design can enable the opening degree adjuster 50 to adjust the opening degrees of the two support rods.

In another embodiment, the minimum adjusting length of the mouth opening adjuster 50 for the orthodontic clinical mouth opening device is larger than the diameter of a human throat in the using process, so that the situation that a patient swallows the mouth opening device by mistake in the using process is avoided.
