Description

Technical Field

[0001] The invention relates to the field of mouth openers, and in particular to a mouth opening function rehabilitation training device. Background Art

[0002] After radiotherapy for head and neck tumors, the radiation can easily cause radiation damage to the temporomandibular joint and the surrounding tissues of the masseter, leading to adhesion and atrophy between the temporomandibular joint and the surrounding tissues, causing complications such as limited joint movement, difficulty opening the mouth, pain, and masticatory muscle stiffness, which seriously affect the patient's life. Clinically, some joint diseases, inflammations, and trauma can also easily cause patients to have difficulty opening their mouths. Therefore, during the treatment process, some auxiliary devices are needed to conduct mouth opening rehabilitation training for patients to help them restore their mouth opening function.

[0003] At present, some commonly used mouth opening training devices, such as Dr. Iseya mouth opening rehabilitation trainer, are used in mouth opening training. The main way to increase resistance is to tie the handle with silicone bandages, and increase the number of bandages to increase resistance. The resistance is increased in steps or in jumps, so that patients cannot slowly adapt to the resistance. At the same time, it is impossible to adjust the maximum mouth opening angle, so it is impossible to accurately grasp the maximum mouth opening angle accepted by the patient during mouth opening training. Summary of the invention

[0004] In response to the problems existing in the background technology, the present invention proposes a mouth opening function rehabilitation training device, which increases the resistance in an infinite manner so that the patient can slowly adapt to the size of the bite resistance, and the maximum limit value is set to be adjustable to prevent the patient or his family from being unable to grasp the maximum value of the mouth opening angle when assisting in training.

[0005] To achieve the above object, the present invention adopts the following technical solution: a mouth opening function rehabilitation training device, comprising a foldable mouth opening component, wherein two ends of the mouth opening component away from the folded end and symmetrically arranged support rods, connecting rods and handles are hinged in sequence;

[0006] An I-shaped base, on which a plurality of vertical hanging ears are symmetrically arranged, the support rod and the handle are hinged on the corresponding vertical hanging ears, the two symmetrically arranged handles are configured to form an angle, and the handles can be folded and rotated in the direction of reducing the angle to drive the opening assembly to open through the connecting rod and the support rod;

[0007] A limit assembly, the limit assembly is arranged within the angle of the handle, is perpendicular to the plane of rotation of the handle and is slidably connected to the base, the body of the limit assembly is a conical structure, when it slides, the conical surface can contact the connecting rods on both sides, limit the minimum value of the angle of the handle, and limit the maximum value of the opening of the opening assembly;

[0008] The resistance adjustment component includes an adjustment rod, a sleeve and a spring. One end of the adjustment rod is rotatably connected to the base, and the other end is threadedly connected to the sleeve. The sleeve is connected to the hinge of the connecting rod and the support rod through the spring. Rotating the adjustment rod can drive the sleeve to move axially along the screw rod, so that the spring deforms and pulls the support rod, thereby increasing the folding resistance of the opening assembly.

[0009] Further, the opening assembly comprises an upper support member and a lower support member, and the upper support member and the lower support member are connected by a flexible material so that the upper support member and the lower support member can be folded along the flexible material;

[0010] Furthermore, the base is provided with a guide rail, the limit assembly is provided with a slide groove corresponding to the guide rail, and the body of the limit assembly is threadedly connected with a screw that can be rotatably connected to the base; when the screw is rotated, it can contact the base to drive the body to slide along the guide rail;

[0011] Furthermore, the main body of the position limiting assembly is also provided with a first scale line distributed along the conical surface, and the minimum angle value of the two symmetrical connecting rods is evaluated through the first scale line to evaluate the maximum opening angle of the opening assembly;

[0012] Furthermore, a measuring component is fixedly connected to the hinge shaft between the support rod and the base, and a second scale line is arranged on the measuring component along the swing direction of the support rod, and the second scale line is distributed in a fan shape, and the swing angle of the support rod is evaluated by the second scale line to evaluate the opening angle of the opening assembly;

[0013] Furthermore, the sleeve can be configured as an electronic elastic meter, and a display is provided on one side of the sleeve to display the elastic force of the spring so as to evaluate the folding resistance value of the opening component.

[0014] Beneficial effects of the present invention: The present invention increases the resistance value when the mouth opening component is folded by providing a pulling support rod at one end of the support rod, and the increasing method is to increase the resistance through the elastic deformation of the spring, so that the resistance is increased in an infinite manner, and the patient can slowly adapt to the size of the bite resistance, thereby training the patient to gradually restore the bite function. In addition, a limit assembly with a conical structure is provided between the handles, and the limit assembly can be used to adjust the minimum clamping limit value of the two symmetrical connecting rods (or handles) to further adjust the maximum limit value of the opening angle of the mouth opening component. During training, the mouth opening angle limit value of the mouth opening component is slowly changed, so that the patient can gradually accept the training intensity, and the patient or family members can accurately grasp the maximum value of the mouth opening angle when assisting in self-training.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0026] In the figure, direction a is the horizontal direction forward, and direction b is the vertical direction upward.

[0027] See also Figures 1 to 9 The invention is a mouth opening function rehabilitation training device, comprising a foldable mouth opening component 1, an I-shaped base 8, a limit component 5, and a resistance adjustment component 7. The two ends of the mouth opening component 1 away from the folded end and the symmetrically arranged support rods 2, connecting rods 3 and handles 4 are hinged in sequence. Figure 2 The middle part is provided with an extension ear 401, which is hinged to the connecting rod 3 through the extension ear 401. The connecting rod 3, the support rod 2, and the first extension rod 103 or the second extension rod 104 (described below) of the opening assembly 1 are hinged through the ends.

[0028] like Figure 1 , Fig. 9 The mouth opening assembly 1 shown includes an upper support member and a lower support member 102, and the upper support member 101 and the lower support member 102 are connected by a flexible material (not shown in the figure), and the flexible material can be configured as soft silicone, so that the upper support member 101 and the lower support member 102 can be folded along the flexible material. The upper support member 101 and the lower support member 102 are respectively fixed with a first extension rod 103 and a second extension rod 104 away from the flexible material end and hinged with the support rod 2. And the upper support member 101 and the lower support member 102 are arranged in a horseshoe structure, respectively buckling the patient's molars on both sides, and are formed by integral injection molding of a bottom plate 1011 and a side plate 1012. When in use, the bottom plates 1011 of the upper support member 101 and the lower support member 102 respectively carry the upper and lower molars, and the side plates 1012 are used to buckle the outer sides of the molars and extend to the incisor part to improve the reliability of the support.

[0029] like Figure 2 , Figure 5 The base 8 is symmetrically provided with a plurality of vertical hanging ears 802, and the support rod 2 is away from the hinged end of the support rod 2 and the first extension rod 103 or the second extension rod 104, and as shown in FIG. Figure 2 The middle part and one end of the handle 4 are hinged on the corresponding vertical hanging ear 802. The two symmetrically arranged handles 4 are configured to form an angle, and the handles 4 can be folded and rotated in the direction of reducing the angle to drive the opening assembly 1 to open through the connecting rod 3 and the support rod 2. When the two handles 4 are folded inward, the handles 4 rotate to push the connecting rod 3 to move forward, and continue to push the two support rods 2 to swing outward along the axis of rotation with the vertical hanging ear 802, driving the first extension rod 103 and the second extension rod 104 of the opening assembly 1, and driving the opening assembly 1 to open outward.

[0030] like Figure 3 , Figure 7 , Figure 8The limit assembly 5 is arranged within the angle of the handle 4, perpendicular to the rotation plane of the handle 4, and slidably connected to the base 8. The body 500 of the limit assembly 5 is a conical structure. When it slides, the conical surface 504 can contact the connecting rods 3 on both sides, limit the minimum value of the angle of the handle 4, and transmit the maximum value of the opening of the limit opening assembly 1. The base 8 is provided with a guide rail 803 perpendicular to the rotation plane of the handle 4, and the limit assembly 5 is provided with a slide groove 501 corresponding to the guide rail 803. The body 500 of the limit assembly 5 is threadedly connected with a screw rod 502 that can be rotatably connected to the base 8. When the screw rod 502 is rotated, it can contact the base 8 to drive the body 500 to slide along the guide rail 803. When the conical surface 504 of the connecting rod 3 contacting the body 500 of the limit assembly 5 is close to the tip, the minimum limit angle of the two handles 4 can be reduced, and the maximum limit angle of the opening assembly 1 can be increased. On the contrary, the maximum limit angle of the opening component 1 can be reduced.

[0031] like Figure 8 The main body 500 of the limit assembly 5 is also provided with a first scale line 503 distributed along the conical surface 504, and the scale line is marked with a corresponding numerical value. The length of the distance that the connecting rod 3 contacts the conical surface 504 and slides along the conical surface 504 is measured, and the numerical value of the first scale line 503 is further used to evaluate the minimum angle of the two symmetrical connecting rods 3 (or the minimum angle of the two handles 4) to evaluate the maximum opening angle of the mouth opening assembly 1. It is convenient to formulate a treatment plan or plan according to the patient's difficulty in opening the mouth, and gradually adjust the maximum limit angle of the mouth opening assembly 1 to train the patient. Allow the patient to gradually accept the intensity of rehabilitation training, and enable the patient or family members to accurately grasp the maximum opening angle when assisting in self-training.

[0032] like Figure 1 , Figure 2 and Figure 4 The resistance adjustment assembly 7 shown in the figure includes an adjustment rod 702, a sleeve 703 and a spring 701. One end of the adjustment rod 702 is rotatably connected to the base 8. Figure 5 As shown, the base 8 is provided with a horizontal hanging ear 801, which is rotatably connected to the adjustment rod 702 through the horizontal hanging ear 801, and the other end of the adjustment rod 702 is threadedly connected to the sleeve 703, and the sleeve 703 is connected to the hinge axis of the connecting rod 3 and the support rod 2 through the spring 701. Rotating the adjustment rod 702 can drive the sleeve 703 to move axially along the screw rod 502, so that the spring 701 is deformed and pulls the support rod 2, thereby increasing the folding resistance of the opening assembly 1. The way to increase the folding resistance value is to increase it through the elastic deformation of the spring 701, so that the resistance increase method is infinitely increased, and the patient can slowly adapt to the size of the bite resistance, thereby training the patient to gradually restore the bite function.

[0033] like Figure 4The sleeve 703 shown can be configured as an electronic dynamometer for measuring the elastic force of the spring 701 to evaluate the folding resistance of the mouth opening component 1, and a display 704 is provided on one side of the sleeve 703 to display the elastic force of the spring 701 to facilitate rehabilitation nursing physicians to evaluate the folding resistance value of the mouth opening component 1.

[0034] like Figure 1 , Figure 2 The hinge axis between the support rod 2 and the base 8 is also fixedly connected with a measuring component 6, which is a fan-shaped structure. The measuring component 6 is provided with a second scale line 601 along the swing direction of the support rod 2. The second scale line 601 is also fan-shaped, and the corresponding angle value is marked on the scale line. The swing angle of the support rod 2 is measured and evaluated through the second scale line 601 to evaluate the opening angle of the opening assembly 1. Figure 6 The support rod 2 is provided with a marking line 201, which sequentially passes through the hinge axis between the support rod 2 and the base 8, and the hinge axis between the support rod 2 and the first extension rod 103 or the second extension rod 104 of the opening assembly 1. When in use, the swing value of the support rod 2 is measured by observing the alignment position of the marking line 201 and the scale line on the measuring component 6, so as to improve the accuracy of evaluating the opening angle of the opening assembly 1.
