Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In this embodiment, referring to fig. 1 to 5, a radiotherapy clinical treatment is with opening a mouth trainer, including being the digging arm 1 and the support frame 9 that the tong arm formula is alternately arranged:

the front end of the movable arm 1 is provided with a supporting arm 2, the end part of the supporting arm 2 is provided with a bent arm 4 which is bent upwards into an arc shape, and the top end of the bent arm 4 is provided with a bulge; the tail end of the movable arm 1 is provided with an end block 7, and the corresponding positions of the opposite inner side surfaces of the end blocks 7 at the two sides are respectively provided with a clamping block 8;

the support frame 9 is U-shaped, the tip butt joint of one side support arm among them of support frame 9 is in the junction of two digging arms 1, the opposite side support arm side of support frame 9 is provided with rotatable adjusting disk 11, the card tooth 13 that is the cockscomb structure is seted up respectively to the corresponding position in border both sides of adjusting disk 11, the fixture block 8 and the card tooth 13 looks adaptation of same side, cantilever 14 is drawn forth at the center of rotation of adjusting disk 11, cantilever 14 extends to the afterbody of digging arm 1 to the tip that the adjusting disk 11 was kept away from to cantilever 14 is provided with swing handle 15.

The movable arm 1 and the supporting arm 2 can be manufactured through injection molding, and the rubber sleeve 3 sleeved on the supporting arm 2 can select a rubber sleeve close to skin, so that discomfort in the oral cavity of a patient during the mouth opening training process is reduced. The supporting arm 2 at the front end of the movable arm 1 can be opened or closed, thereby achieving the purpose of mouth opening training

In this embodiment, the movable arm 1 and the supporting arm 2 are integrally formed, the material of the movable arm 1 and the supporting arm 2 is alloy or plastic, the supporting arm 2 is sleeved with the rubber sleeve 3, and the movable arms 1 are connected through the elastic hinge shaft.

Because the two movable arms 1 are connected through the elastic hinge shaft, the elastic connection between the movable arms 1 can improve the resilience and ensure that a patient can continuously perform mouth opening training.

In this embodiment, the movable arms 1 at two sides are respectively provided with a notch groove 5 at the corresponding position of the inner side of the rear half section of the connection position, a spring 6 is arranged between the notch grooves 5 at two sides, and two ends of the spring 6 are respectively butted on the groove walls of the notch grooves 5 at two sides.

Similarly, another elastic connection mode is adopted to increase the rotation resilience between the two movable arms 1, so that the continuous performance of the mouth opening training of the patient can be ensured.

In this embodiment, a plurality of sets of latches 13 are provided at the edge of the disk surface of the adjusting disk 11, the diameter of the virtual circle where the contour of the latch 13 on the same side is located is sequentially reduced, a gap is reserved on the support arm side of the support frame 9 facing the adjusting disk 11, an installation plate 16 is provided in the gap, a spring shaft 10 is provided on the installation plate 16, a through hole 12 is provided at the rotation center of the adjusting disk 11, the spring shaft 10 is inserted into the through hole 12, the end of the spring shaft 10 is fixed to the end of the cantilever 14 through a bearing component in a butt joint manner, and the cantilever 14 coincides with the straight line where the center lines of the two movable.

Referring to fig. 1, the adjusting plate 11 can rotate under the driving of the rotating force of the cantilever 14, because the end block 7 at the tail end of the movable arm 1 on both sides always keeps the trend of inward rotation, therefore, the clamping block 8 on the end block 7 can be limited in the latch 13, or slide along the external arc surface of the latch 13, when the adjusting plate 11 rotates clockwise, the patient can rotate the adjusting plate 11 by a corresponding angle according to the requirement of mouth opening training, so as to ensure that the clamping block 8 can be clamped in the adaptive latch 13, thereby ensuring that the supporting arm 2 at the front end of the movable arm 1 can be opened to a proper angle. The adjusting disk 11 is driven by the spring shaft 10 to keep the trend of anticlockwise rotation, but because the limiting effect of the fixture block 8 is received at the moment, the adjusting disk 11 is kept at a fixed position and cannot be changed, and similarly, because the latch 13 and the fixture block 8 are restricted with each other, the positions of the movable arm 1 and the supporting arm 2 at the end part of the movable arm 1 are also fixed and cannot be changed, so that the state of a patient in mouth opening can be ensured not to be changed, and the mouth opening training effect is ensured.

The specific working principle is as follows: firstly, according to the requirement of the mouth opening training amplitude of a patient, rotating a rotary handle 15, and rotating an adjusting disc 11 to enable a supporting arm 2 at the moment to be opened to an almost proper amplitude, which is a rough adjustment process; then, the supporting arms 2 and the bent arms 4 extend into the oral cavity of the patient, one of the supporting arms 2 is ensured to abut against the palate, the other supporting arm 2 abuts against the tongue, at the moment, the rotating handle 15 is further rotated, and the distance between the two supporting arms 2 is more accurately limited through the rotation of the adjusting disc 11, so that the accurate mouth opening amplitude is finally obtained in the fine adjustment process, and the distance between the two supporting arms 2 under the finally obtained mouth opening amplitude is fixed and unchanged, so that the training effect is ensured. Here, because the distance between two brace arms 2 can be changed by man, therefore, it can be applicable to the people of different training range of opening, thereby the application range of this equipment is obviously expanded.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
