Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a temporomandibular joint manipulation treatment guide. Background Art

[0002] With the changes in modern lifestyles and eating habits, the incidence of oral diseases has gradually increased, among which temporomandibular joint disorder has become a public health issue worthy of attention. Temporomandibular joint disorder may be caused by a variety of factors, including but not limited to inflammation of the temporomandibular joint, articular disc displacement, muscle tension, and poor tooth occlusion. These conditions not only cause symptoms such as facial pain and difficulty chewing, but may also affect the patient's quality of life. In addition, with the high incidence of neurological diseases such as craniocerebral injury, stroke, and impaired consciousness, temporomandibular joint disorders such as abnormal dislocation of the temporomandibular joint and abnormal mouth opening due to abnormal tension are also becoming increasingly serious.

[0003] At present, manual therapy occupies an important position in the conservative treatment of temporomandibular joint disorders. Although there are some auxiliary tools for opening the mouth on the market, such as clamp-handle, T-shaped, and square-shaped mouth openers, which can help control the opening range of the mouth and facilitate inspections, surgery, or intubation, manual therapy for joint loosening, soft tissue traction, disc slippage, and reduction still mainly relies on the operator to operate directly in the mouth. At present, there are no auxiliary tools that are more targeted and can improve the success rate and efficiency of the operation.

[0004] Direct operation in the oral cavity can easily bring the risk of secondary injury to the patient and often cause discomfort to the patient. These operations require high skills of the operator, and may cause damage to the operator's own fingers or bite the tongue if not careful. Although there are some auxiliary tools on the market, such as tongue depressors, these tools can only provide simple operation protection and lack effective auxiliary functions and good operability. In the face of the needs of joint loosening and reduction manipulation, especially for oral cavity with different opening degrees, how to guide the temporomandibular joint to slide forward and backward, move laterally, adjust the articular disc displacement and joint reduction without direct contact with the oral cavity has become an urgent problem to be solved. Existing auxiliary tools do not perform well in achieving these complex movements and cannot meet clinical needs. Summary of the invention

DETAILED DESCRIPTION

[0034] The present invention is further described in conjunction with the following examples.

[0035] Embodiment 1, by Figures 1 to 5 It can be seen that the temporomandibular joint manipulation treatment guide described in this embodiment includes a bottom core 1 and a first sleeve 3 movably sleeved outside the bottom core 1; a cone head 2 is provided at one end of the bottom core 1; and a first rotating part 11 is provided at the other end of the bottom core 1;

[0036] A flat portion 21 is disposed at one end of the cone head 2 away from the bottom core 1 ; a first conical surface 22 is disposed at one end of the cone head 2 close to the bottom core 1 .

[0037] A second conical surface 31 is disposed at one end of the first sleeve 3 close to the cone head 2 ; a second rotating portion 32 is disposed at one end of the first sleeve 3 away from the cone head 2 .

[0038] Specifically, when the temporomandibular joint manipulation therapy guide described in this embodiment is used, the cone head 2 is first inserted into the oral cavity. Since the end of the cone head 2 is a flat portion 21 with a flat structure, it can easily enter between the upper and lower teeth. Then, the first sleeve 3 is gradually driven to move in the direction of the cone head 2, so that the end of the first sleeve 3 abuts against the oral cavity, and the first conical surface 22 and the second conical surface 31 are used to gradually assist the patient to open his mouth, so as to achieve the purpose of operating in accordance with the different opening requirements of the upper and lower oral cavity.

[0039] In the guide device for manipulative treatment of temporomandibular joint described in this embodiment, the outer wall of the bottom core 1 is provided with a first external thread 12; the inner wall of the first sleeve 3 is provided with a first internal thread 33 that matches the first external thread 12. Through the above arrangement, when the flat portion 21 reaches between the upper and lower teeth, it is only necessary to rotate the first sleeve 3, that is, under the action of the first external thread 12 and the first internal thread 33, the first sleeve 3 can be moved toward the direction of the cone head 2, thereby assisting the patient to increase the opening of the upper and lower oral cavity.

[0040] When the second conical surface 31 at the front end of the first sleeve 3 is located near the upper and lower molars on one side, the upper and lower jaws mainly bite the first sleeve 3 and roll the guide back and forth between the teeth, thereby achieving the purpose of dynamic joint delivery; what is more exciting is that the first sleeve 3 can provide a fulcrum for the mandibular molars, and provide an upward force on the chin, which can achieve traction of the temporomandibular joint and achieve the purpose of retracting the abnormal folded articular disc.

[0041] In the guide device for manual therapy of temporomandibular joint described in this embodiment, the outer wall of the other end of the bottom core 1 is provided with a first slide groove 13 along the axial direction; a first locking block 14 is slidably provided in the first slide groove 13; the inner wall of the end of the first sleeve 3 away from the cone head 2 is provided with a first limiting groove 34 cooperating with the first locking block 14 along the axial direction; the first locking block 14 is provided with a first stopper 15 abutting against the end face of the first sleeve 3. Specifically, after adjusting the position of the first sleeve 3 in the bottom core 1, the first locking block 14 is pushed in the first slide groove 13 until the first locking block 14 is inserted into the first limiting groove 34, and the first stopper 15 abuts against the end of the first sleeve 3, so that the bottom core 1 and the first sleeve 3 are connected as a whole, preventing the first sleeve 3 and the bottom core 1 from relative rotation, and enhancing the overall stability.

[0042] The temporomandibular joint manipulation therapy guide device described in this embodiment further includes a second sleeve 4 movably sleeved outside the first sleeve 3; a third conical surface 41 is provided at one end of the second sleeve 4 close to the cone head 2; a third rotating portion 42 is provided at one end of the second sleeve 4 away from the cone head 2;

[0043] Specifically, when the end of the first sleeve 3 abuts against the oral cavity, the second sleeve 4 can be gradually driven to move in the direction of the cone head 2, so that the end of the second sleeve 4 abuts against the oral cavity, and the third cone surface 41 gradually assists the patient to open the mouth, so as to further achieve the purpose of operation suitable for different opening requirements of the upper and lower oral cavity.

[0044] When the third conical surface 41 at the front end of the second sleeve 4 is near the upper and lower molars on one side, the dislocated temporomandibular joint can be automatically reset by mainly biting the second sleeve 4 with the upper and lower jaws and rolling the guide back and forth between the teeth. At the same time, when the temporomandibular joint is reset, the mandibular physiological closing movement will occur. At this time, there is a guide between the teeth, so that the mandibular on the reset side can be in an open mouth state, avoiding the tongue biting and other undesirable scenes caused by this closing movement. The guide is a medical device that can achieve the purpose of reset in a safe, reliable, simple and easy way. When the operator is unable to cooperate actively, the operator can easily achieve reset by simply moving the mandible back and forth. What's more exciting is that the second sleeve 4 can provide a fulcrum for the mandibular molars, and provide an upward force on the chin to achieve traction of the temporomandibular joint, so as to achieve the purpose of retracting the folded abnormal articular disc.

[0045] The outer wall of the first sleeve 3 is provided with a second external thread 35; the inner wall of the second sleeve 4 is provided with a second internal thread 43 that cooperates with the second external thread 35; through the above arrangement, when the end of the first sleeve 3 is in contact with the oral cavity, it is only necessary to rotate the second sleeve 4, that is, under the action of the second external thread 35 and the second internal thread 43, the second sleeve 4 can be moved toward the direction of the cone head 2, thereby assisting the patient to increase the opening of the upper and lower jaws.

[0046] In the present embodiment, a guide for manual therapy of the temporomandibular joint is provided, wherein the outer wall of the end of the first sleeve 3 away from the cone head 2 is axially provided with a second slide groove 36; a second locking block 37 is slidably provided in the second slide groove 36; the inner wall of the end of the second sleeve 4 away from the cone head 2 is axially provided with a second limiting groove 44 cooperating with the second locking block 37; the second locking block 37 is provided with a second stop block 38 abutting against the end face of the second sleeve 4.

[0047] Specifically, after adjusting the position of the second sleeve 4 in the first sleeve 3, the second locking block 37 is pushed in the second slide groove 36 until the second locking block 37 is inserted into the second limiting groove 44, and the second stop block 38 abuts against the end of the second sleeve 4, so that the bottom core 1, the first sleeve 3 and the second sleeve 4 are connected as a whole, preventing relative rotation between the first sleeve 3, the second sleeve 4 and the bottom core 1, and enhancing the overall stability.

[0048] The present embodiment describes a temporomandibular joint manipulation therapy guide, which also includes a third sleeve 5 movably sleeved on the outside of the second sleeve 4; the third sleeve 5 is provided with a fourth conical surface 51 at one end close to the cone head 2; the third sleeve 5 is provided with a fourth rotating portion 52 at one end away from the cone head 2; specifically, when the end of the second sleeve 4 abuts against the oral cavity, the third sleeve 5 can be gradually driven to move toward the direction of the cone head 2, so that the end of the third sleeve 5 abuts against the oral cavity, and the fourth conical surface 51 is used to gradually assist the patient to open the oral cavity, so as to further achieve the purpose of operation suitable for different opening requirements of the upper and lower oral cavity.

[0049] When the fourth conical surface 51 at the front end of the third sleeve 5 is located near the upper and lower molars on one side, the dislocated temporomandibular joint can be automatically reset by the upper and lower jaws mainly biting the third sleeve 5 and rolling the guide back and forth between the teeth; the guide is a medical device that can achieve the purpose of reset in a safe, reliable, simple and easy manner; when the operator is unable to actively cooperate, the operator can also easily achieve reset by simply moving the lower jaw back and forth; what is more exciting is that the third sleeve 5 can provide a fulcrum for the mandibular molars, and provide an upward force on the chin, so as to achieve traction of the temporomandibular joint and achieve the purpose of retracting the folded abnormal articular disc.

[0050] The outer wall of the second sleeve 4 is provided with a third external thread 45; the inner wall of the third sleeve 5 is provided with a third internal thread 53 that matches the third external thread 45; through the above arrangement, when the end of the second sleeve 4 is against the oral cavity, it is only necessary to rotate the third sleeve 5, that is, under the action of the third external thread 45 and the third internal thread 53, the third sleeve 5 can be moved toward the cone head 2, thereby assisting the patient to further increase the opening of the upper and lower jaws. The outer wall thread can also be provided on the outer wall of the third sleeve 5, which can increase the friction force between it and the teeth, greatly increase the movement efficiency of the mandible, and make joint loosening and reduction techniques easier to perform.

[0051] In the present embodiment, a guide for manipulative treatment of temporomandibular joints is provided with a third slide groove 46 along the axial direction on the outer wall of the end of the second sleeve 4 away from the cone head 2; a third locking block 47 is slidably provided in the third slide groove 46; a third limiting groove 54 cooperating with the third locking block 47 is provided along the axial direction on the inner wall of the end of the third sleeve 5 away from the cone head 2; and the third locking block 47 is provided with a third stopper 48 abutting against the end face of the third sleeve 5. Specifically, after the position of the third sleeve 5 is adjusted, the third locking block 47 is pushed in the third slide groove 46 until the third locking block 47 is inserted into the third limiting groove 54, and the third stopper 48 abuts against the end of the third sleeve 5, so that the bottom core 1, the first sleeve 3, the second sleeve 4 and the third sleeve 5 are connected as a whole, and relative rotation between the first sleeve 3, the second sleeve 4, the third sleeve 5 and the bottom core 1 is prevented, and the overall stability can be enhanced.

[0052] In the present embodiment of the present invention, the guide device for manipulative treatment of the temporomandibular joint is provided, wherein the length of the bottom core 1 is greater than the length of the first sleeve 3; the length of the first sleeve 3 is greater than the length of the second sleeve 4; the length of the second sleeve 4 is greater than the length of the third sleeve 5; the length of the third sleeve 5 is greater than the length of the fourth sleeve; the above arrangement allows sufficient space for movement between adjacent sleeves;

[0053] The bottom core 1, the first sleeve 3, the second sleeve 4 and the third sleeve 5 are coaxially arranged;

[0054] The radius of the bottom core 1, the radius of the first sleeve 3, the radius of the second sleeve 4 and the radius of the third sleeve 5 increase in sequence; the above arrangement makes the overall structure stable and reliable.

[0055] The radius of the fourth conical surface 51, the radius of the third conical surface 41, the radius of the second conical surface 31 and the radius of the first conical surface 22 decrease in sequence; the above arrangement can gradually help the user open the upper and lower oral cavity.

[0057] In the temporomandibular joint manipulation treatment guide described in this embodiment, the bottom core 1 is threadedly connected with the cone head 2. The above arrangement facilitates the replacement of the bottom core 1 and the cone head 2.

[0058] Embodiment 2, by Figure 6 to Figure 7It can be seen that, different from the embodiment 1, in the guide device for manipulative treatment of the temporomandibular joint described in this embodiment, an upper clamping block 71 and a lower clamping block 72 are movably provided at one end of the bottom core 1; the cone head 2 is provided with a clamping groove 23 for clamping with the upper clamping block 71 and the lower clamping block 72; the upper clamping block 71 and the lower clamping block 72 are respectively connected with an upper pressing block 73 and a lower pressing block 74; a spring 75 is provided between the upper pressing block 73 and the lower pressing block 74.
