Description

Technical Field

[0001] This utility model belongs to the field of medical technology, and in particular relates to a temporomandibular joint protraction trainer. Background Technology

[0002] The temporomandibular joint (TMJ) is the only bilateral joint in the maxillofacial region that is highly stable and capable of multidirectional movement. It plays a crucial role in daily activities such as chewing and swallowing, as well as speech and facial expressions. The TMJ is closely connected to the head, neck, and shoulders. Increased periods of poor posture, such as prolonged desk work or looking down at a mobile phone, lead to incoordination of the masticatory muscles and surrounding neck muscles. This results in the mandible being in a retracted state for extended periods, affecting TMJ function and increasing the risk of anterior TMJ disc dislocation, causing joint clicking and limited mouth opening. This paper proposes a structure that can train the TMJ to extend forward. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a temporomandibular joint protraction trainer, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a temporomandibular joint protrusion trainer, comprising a housing and further comprising: a protrusion assembly for assisting mandibular protrusion; the protrusion assembly comprises a slide, a push rod, and an arc plate, wherein the slide is slidably connected to the housing, the push rod is slidably connected to the slide, the arc plate is fixedly connected to the push rod, and an anti-slip pad is attached to the arc plate.

[0005] Beneficial effects

[0006] This invention provides a temporomandibular joint protraction trainer, which has the following advantages compared with the prior art:

[0007] The patient places the shell portion into their mouth, biting down on bite plate A with their upper teeth and bite plate B with their lower teeth. Care should be taken to avoid excessive biting force. The adhesive pads on bite plate A and bite plate B effectively prevent tooth damage and expand the patient's oral cavity. The patient then wraps the Velcro straps on both sides of the shell around the back of their neck, tightens them, and secures them together. The user then manually rotates the turntable, causing the screw A, fixed to the turntable's axis, to rotate synchronously. The sliding sleeve connected to screw A then moves the slide, which in turn pushes the curved plate until it rests against the patient's lower jaw. The patient can then slowly extend their lower jaw forward. Because the lower teeth are biting down on bite plate B, they can slide along the shell using bite plate B, thus reducing... Damping is applied to the mandibular protrusion. At this time, the push rod retracts into the slide and pushes the slide plate fixedly connected to it to slide synchronously. The slide plate then begins to compress the spring fixedly connected to it, so that the spring provides a reaction force to the slide plate. Thus, during the process of the patient's mandibular protrusion pushing the arc plate to slide, the spring provides resistance to it, thereby increasing the effect of the patient's mandibular protrusion exercise. At the same time, the patient can rotate the turntable B, which causes the screw B fixedly connected to its axis to start rotating. At this time, the slide cylinder threaded on the screw B begins to move linearly along its connection with the shell. This causes the slide cylinder to drive the top rod hinged on it to slide synchronously. At this time, the top rod begins to push the bite plate A hinged to it, causing the bite plate A to rotate upward with its hinge with the shell as the fulcrum, thereby adjusting the degree of oral expansion of the patient.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0014] Please see Figures 1-3 According to one embodiment of the present invention, a temporomandibular joint protrusion trainer includes a housing 101 and further includes:

[0015] Forward extension component 2 is used to assist in mandibular protrusion;

[0016] The forward extension assembly 2 includes a slide 201, a push rod 202, and an arc plate 203. The slide 201 is slidably connected to the housing 101, the push rod 202 is slidably connected to the slide 201, and the arc plate 203 is fixedly connected to the push rod 202. An anti-slip pad is attached to the arc plate 203.

[0017] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific housing 101 described in the above embodiments. For example, the housing 101 has a male and female side with Velcro on both sides. The purpose of this arrangement is to facilitate fixing the housing 101 to the patient's mouth with Velcro and prevent it from falling off.

[0018] Specifically, the other end of the push rod 202 is fixedly connected to the slide plate 204, and guide rods 205 are symmetrically slidably connected to both sides of the slide plate 204. The guide rods 205 are fixedly connected to the slide table 201.

[0019] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific guide rod 205 described in the above embodiments. For example, the guide rod 205 is provided with a damping rubber strip. The purpose of this setting is to increase the damping of the sliding plate 204, so that it can slide smoothly and avoid the excessive elasticity of the spring 206 causing the sliding plate 204 to slide quickly.

[0020] Specifically, a spring 206 is sleeved on the guide rod 205. One end of the spring 206 is fixedly connected to the slide plate 204, and the other end of the spring 206 is fixedly connected to the slide table 201.

[0021] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific spring 206 described in the above embodiments. For example, the spring 206 can be replaced by a cylinder, which is fixedly connected to the slide table 201, and the piston rod of the cylinder is fixedly connected to the slide plate 204. The purpose of this arrangement is to facilitate precise control of the sliding of the slide plate 204.

[0022] Specifically, a sliding sleeve 208 is fixedly connected to the slide table 201, the sliding sleeve 208 is threadedly connected to the lead screw A207, the lead screw A207 is rotatably connected to the housing 101, and a turntable 209 is fixedly connected to the lead screw A207.

[0023] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific lead screws A207 and B301 described in the above embodiments. For example, the lead screws A207 and B301 should be lead screws with a self-locking effect. The purpose of this setting is to facilitate the limiting effect of the slider connected to the thread on it.

[0024] Specifically, a lead screw B301 is rotatably connected to the housing 101, and a slide cylinder 302 is threadedly connected to the lead screw B301. The slide cylinder 302 is slidably connected to the housing 101.

[0025] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific lead screws B301 and A207 described in the above embodiments. For example, one end of the lead screws B301 and A207 can be fixedly connected to the output shaft of the motor. The purpose of this arrangement is to facilitate the synchronous rotation of the lead screws B301 and A207 through this arrangement.

[0026] Specifically, a top rod 303 is hinged to the slide cylinder 302, and the other end of the top rod 303 is hinged to the bite plate A304. One side of the bite plate A304 is rotatably connected to the housing 101, and sealing strips are provided at the edges of the slide plate 204.

[0027] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific biting plate A304 and biting plate B306 described in the above embodiments. For example, both biting plate A304 and biting plate B306 are provided with rubber pads. The purpose of this arrangement is to facilitate the cushioning of the patient's teeth when biting on them.

[0028] Specifically, a turntable B305 is fixedly connected to the lead screw B301, and a bite plate B306 is slidably connected to the bottom of the housing 101.

[0029] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific biting plate B306 described in the above embodiments. For example, the connection between the biting plate B306 and the housing 101 should be relatively smooth to reduce the friction on its sliding, thereby avoiding excessive resistance when the patient pushes the biting plate B306.

[0030] In this embodiment of the invention, the patient places part of the shell 101 into their mouth, simultaneously biting down on the biting plate A304 with their upper teeth and on the biting plate B306 with their lower teeth. Care should be taken to control the biting force during occlusion to avoid excessive force. The adhesive pads on the biting plates B306 and A304 effectively prevent damage to the patient's teeth, thereby expanding the oral cavity. The patient then wraps the Velcro straps on both sides of the shell 101 around the back of their neck, tightens them, and secures them together. At this point, the patient can use... The patient manually rotates the turntable 209, causing the lead screw A207, fixedly connected to the axis of the turntable 209, to rotate synchronously. At this time, the sliding sleeve 208 threaded onto the lead screw A207 begins to drive the slide table 201 to slide, which in turn pushes the arc plate 203 to slide until the arc plate 203 fits against the patient's mandible. The patient can then slowly extend their mandible forward. Simultaneously, because the patient's lower teeth are occlusal on the biting plate B306, they can slide on the housing 101 via the biting plate B306. To reduce the damping of mandibular protrusion, push rod 202 retracts into slide 201, causing push rod 202 to push slide plate 204, which is fixedly connected to it, to slide synchronously. At this time, slide plate 204 begins to compress spring 206, which is fixedly connected to it, so that spring 206 provides a reaction force on slide plate 204. Thus, during the process of the patient's mandibular protrusion pushing the arc plate 203 to slide, spring 206 can provide resistance to it, thereby increasing the effect of mandibular protrusion exercise. At the same time, the patient can rotate turntable B305 to start rotating the screw B301 fixedly connected to its axis. At this time, slide cylinder 302 threaded on screw B301 begins to move linearly along its connection with housing 101. Thus, slide cylinder 302 drives the top rod 303, which is hinged to it, to slide synchronously. At this time, top rod 303 begins to push bite plate A304, which is hinged to it, so that bite plate A304 rotates upward with its hinge with housing 101 as the fulcrum, thereby adjusting the degree of oral expansion of the patient.
