Description

Technical Field

[0001] The invention relates to the technical field of surgical instruments, in particular to a device for training the function of difficult mouth opening. Background Art

[0002] The incidence of difficulty opening the mouth, a long-term adverse reaction in patients undergoing radiotherapy for head and neck tumors, is 5% to 10%. In the prior art, functional training tools designed for patients with difficulty opening their mouths have certain technical problems. For example, when a T-shaped mouth opener is used to train the patient's mouth to open, it is not possible to easily know the relative degree of opening between the upper and lower teeth, or to accurately adjust the size of the patient's mouth opening. Using this training tool to make the patient's mouth open and close reciprocally will inevitably cause the patient to feel fatigued during oral exercises, and even cause oral muscle strain in the patient.

[0003] The mouth opening training device in the current prior art uses two training plates to drive the upper teeth and the lower teeth to move in opposite directions, thereby achieving mouth opening training. However, the training plates of the device are usually of fixed size. In order to allow different people to use them, the cross-section is generally not large. This also results in a small contact area between the training plates and the human teeth during actual use, and the force is borne by only a few teeth, making training inconvenient. In addition, during the mouth opening process, the human chin will move downward, while the human head will tend to move upward. For people who have difficulty opening their mouths, ordinary training devices lack measures to limit the patient's head, which may cause the human head to move upward during training, thereby affecting the effect of the mouth opening training. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a functional training device for difficulty in opening the mouth to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure and limits the chin and head of a person through a limiting component. During mouth opening training, the support pad moves with the chin and squeezes the top strap to prevent it from moving upward, thereby preventing the patient's head from following the movement and affecting the training effect. Through the cooperation of the moving component and the training component, the range of the cushion can be adjusted according to the size of the patient's oral opening, so that the cushion can contact more teeth, thereby improving the stability and convenience of mouth opening training without damaging the teeth.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention has two groups of soft pads corresponding to the upper and lower gums respectively, and the soft pads correspond to two groups of inserting frames and inserting plates, which are located on the opposite side of the soft pads contacting the teeth, and the two inserting plates at the rear end are slidably connected to the side plates through the connecting blocks, ensuring that the inserting plates, the soft pads and the horizontal movement direction are the same as the side plates, so that the two can be replaced by relying on the moving assembly, and because the connecting blocks are connected to the sliding grooves of the side plates, when the side plates move laterally to adjust the distance, the inserting plates will also move along the inserting frames to adjust the length of the front end of the soft pads, with the front end of the soft pads as the position for tooth occlusion, and the inserting frames at the front and rear ends of the soft pads are connected by a reset spring to limit the excess soft pads, and the soft pads are bonded to the inserting frames and the inserting plates at three points in the middle and at both ends, and can be torn off and replaced with new soft pads after use to avoid cross infection.

[0017] 2. The present invention uses artificial assistance to sleeve the groove of the cushion on the teeth, and then by turning the knob, the transmission belt drives the gear to rotate and mesh with the toothed plates on both sides, the toothed plates slide along the vertical plates and drive the corresponding second horizontal frame to move, and the connecting rod drives the two groups of cushions to push the mouth to open in opposite directions through the plug plate, thereby realizing the training of opening the mouth. The sliding connection between the toothed plate and the vertical plate is the most common sliding structure, which is not shown in the figure. The position of the knob can be locked by rotating the fixing bolt to squeeze and contact the vertical plate after opening the mouth, so as to maintain the position of the cushion and the opening of the mouth, and the side plate will move with the plug plate. In this process, the side plate is connected to the tail plate through the second telescopic plate. Before training, the side plate is in front and the cushion is in the back. There is an inclined surface on the front end surface of the side plate for easy insertion into the mouth. After the mouth is initially pushed open, the second bidirectional screw is rotated, the tail plate drives the side plate to move along the first horizontal frame, the plug plate moves along the plug frame, and the connecting rod moves along the second horizontal frame. The length of the cushion is adjusted according to the spacing between the two side plates. After the side plate is adjusted to the width of the patient's mouth, the position of the cushion and the side plate is switched.

[0018] 3. The present invention rotates the first bidirectional screw, and the two sliders cooperate with the first bidirectional screw thread to slide along the slide frame, so that the movement directions of the first horizontal frame and the second horizontal frame are opposite, so that the side panel can open the mouth first, and then the soft pad can be switched to wrap the teeth to train the mouth opening.

[0019] 4. The present invention allows the patient's head to enter the operation groove, with the chin placed on the support pad and the straps in contact with the top of the head. The positions of the cushion and the straps are adjusted by the elastic force of the first spring telescopic rod and the second spring telescopic rod, and the length of the first telescopic plate is adjusted at the same time so that the pressure plate on its top is temporarily not in contact with the connecting plate. The length of the first telescopic plate is fixed by the locking bolt. When performing mouth opening training, the person's chin will move downward and be supported by the support pad and the first spring telescopic rod. At this time, the position of the connecting plate is restricted by the cooperation of the cross plate, the frame, the first telescopic plate and the pressure plate, so that it cannot move upward, thereby keeping the head still for mouth opening training.

[0020] 5. Compared with the prior art, the present invention limits the chin and head of a person through a limiting component. During mouth opening training, the support pad moves with the chin and squeezes the top strap, preventing it from moving upward, thereby preventing the patient's head from following the movement and affecting the training effect. Through the cooperation of the moving component and the training component, the range of the cushion can be adjusted according to the size of the patient's oral opening, so that the cushion can contact more teeth, thereby improving the stability and convenience of mouth opening training without damaging the teeth.
