Description

An adjustable tongue muscle rehabilitation training device after partial tongue resection

Technical field

The invention relates to the field of medical rehabilitation training equipment, and in particular to an adjustable tongue muscle rehabilitation training device after partial tongue resection.

Background technique

The tongue is an important organ in the human oral and maxillofacial region. The hypoglossal nerve innervates the tongue muscles to drive tongue movement to assist in pronunciation and eating. Therefore, tongue movement disorders will affect the patient's diet and daily communication, bringing a lot of inconvenience to the patient's life. . Tongue cancer is the oral cancer with the highest incidence rate. Its main treatment method is partial tongue resection, which requires the removal of cancer nests within normal tissue along the edge of the tumor. During the operation, part of the tongue muscle will be removed to destroy the integrity of the tongue body. Affects the motor function of the tongue. Therefore, after partial glossectomy, patients may develop complications such as unclear pronunciation and difficulty eating due to tongue movement disorders, which seriously reduces the patient's quality of life, and the social barriers caused by unclear pronunciation also have a great impact. improve the patient's mental health and social adaptability. In order to solve the problem of postoperative tongue movement disorders, doctors will instruct patients to perform tongue rehabilitation exercises after surgery to partially restore tongue function and improve quality of life.

Currently, only simple auxiliary tongue pulling devices can be used for tongue muscle rehabilitation training in patients after partial glossectomy, and there is a lack of specialized rehabilitation training devices. The existing tongue muscle training devices have three shortcomings: first, this part of the device only passively pulls the tongue body. The patient has no active tongue movement during training, the tongue muscles have no force, and rehabilitation training has almost no effect; Secondly, some devices use piston-type negative pressure suction, which requires most of the tongue body to be intact to obtain sufficient edge sealing for suction, which is obviously not suitable for patients with missing tongue parts; finally, the current device cannot measure the tongue body. The range of motion cannot accurately reflect the intensity and effect of training, so it is impossible to formulate an individualized training plan, and the training effect is poor.

The distance between adjacent positioning holes 203 is 5 mm, which facilitates the patient to adjust the training intensity when using the training device.

The fixed section 201 and the movable section 202 of the caliper 20 are both provided with chute distributed along the axial direction, and scales are provided on both sides of the chute, and the accuracy of the scale is millimeters.

The tongue extension training component 40 is slidably disposed in the chute of the caliper 20 and is used to train the extension movement of the tongue body and enhance the strength of the tongue muscles. The tongue extension training component 40 includes a tongue support 401, a force transmission rod 402 and an elastic member 403.

The tongue support 401 has a "U"-shaped structure, which is convenient for the patient to insert the tongue body for fixation and then exert force. The tongue support 401 is made of plastic as a whole, and the middle part of one end thereof is connected to the power transmission rod 402.

The transmission rod 402 has an "L"-shaped structure as a whole, with one end connected to the tongue support 401 and the other end connected to the lower slide 405. When the patient uses the device, the tongue exerts force to push the transmission rod 402 through the tongue support 401.

The upper slider 404 is slidably disposed above the chute, and the lower slider 405 is slidably disposed below the chute. The upper slider 404 and the lower slider 405 are connected together through one or more connecting columns to transmit force. The rod 402 moves together with the upper slider 404 and the lower slider 405; the connecting column is a square prism, and its two sides are connected with the side walls of the chute to ensure that the upper slider 404 and the lower slider 405 will not tilt due to sliding. And got stuck.

An elastic member 403 is connected to the side of the power transmission rod 402 away from the tongue support 401 . The elastic member 403 is a spring; the axial direction of the spring is perpendicular to the power transmission rod 402 and the spring expands and contracts along the axial direction of the caliper 20 .

The overall structure of the movable section 202 of the caliper 20 is "L" shaped. One end of the spring is connected to the side wall of the "L" shaped movable section 202, and the other end is connected to the power transmission rod 402.

When the patient's tongue pushes the power transmission rod 402 through the tongue support 401, the power transmission rod 402 slides forward and compresses the spring. During the process of compressing the spring, the tongue body muscles need to exert force, so the tongue muscles are well strengthened. Strength Training.

In order to ensure that the patient needs to replace the spring at different training stages to increase the training intensity, both ends of the spring are fixed on a circular collar respectively, and at the same time, the rod wall of the power transmission rod 402 and the caliper 20 of the "L" shaped movable section 202 Corresponding hooks are provided on both sides, and the collar is directly connected to the hook to complete the installation of the spring.

The tongue-raising training component 30 is arranged at the central palatal vault of the dental tray 10 and is used to train the patient's tongue to perform tongue-raising and tongue-circling movements to increase the flexibility of the tongue.

The training ball 301 is connected to the lower part of the reset soft handle 302, and the upper part of the reset soft handle 302 is bonded to the central palatal vault of the dental tray 10 through high-strength waterproof glue; training The ball 301 and the reset soft handle 302 are made of elastic silicone.

In addition to the training function, the rehabilitation training device of the present invention can measure the patient's maximum tongue extension length after removing the spring. The traditional measuring operation with a ruler is not only inconvenient, but also has low patient comfort. The rehabilitation training device of the present invention overcomes the shortcomings of measuring with a ruler and makes the measurement more standard. After wearing the rehabilitation training device, the patient installs the movable section 202 of the caliper 20 to the farthest distance from the thickened part 101 and removes the spring; the patient actively extends his tongue and uses the tip of his tongue to push the tongue support 401, and then withdraws after reaching the limit, and the tongue support 401 It will be fixed at the maximum tongue extension position, and the measurement can be completed by reading the scale on the scale. The maximum tongue extension length measured by the rehabilitation training device of the present invention starts from the maxillary incisor papilla. The tongue extension length is the length from the incisor papilla to the tip of the tongue. For patients with missing maxillary anterior teeth, it is the maxillary anterior tooth area. The distance from the crest of the groove to the tip of the tongue.

The working principle of the rehabilitation training device of the present invention:

(1) Tongue raising/rapping training:

After the patient wears the rehabilitation training device, he actively lifts his tongue to touch the training ball 301 located above the palatal vault to train the tongue lifting/rapping function. When the patient lifts his tongue and feels the ball, he can use this as a force point to swing. Tongue body, since the ball and the reset soft handle 302 are both made of elastic silicone material, they can change their position with the force. When the tongue body is relaxed, the ball and the reset soft handle 302 will return to their original positions. In this way, the patient can be trained to lift the tongue/ Rap function.

(2) Training of tongue extension function:

Since the tongue muscle training patient's initial tongue protrusion function is very poor, after wearing the rehabilitation training device, the patient first fixes the movable section 202 of the caliper 20 at the minimum range so that the patient can feel the tongue support 401 with the tip of his tongue and perform speech through the tongue support 401. force. The patient actively extends his tongue to push the tongue support 401 to slide forward. During this process, the spring is compressed and will produce a reaction force to resist the tongue extension movement. Therefore, the patient will feel resistance when extending his tongue. When the patient trains multiple times at the minimum range and can When the spring is pressed to the minimum length, the movable section 202 of the caliper 20 can be adjusted to reach a further distance. The patient repeats the above process and extends the tongue again to push the tongue support 401 to move forward in a cycle. After reaching the target, the tongue support 401 is continuously adjusted to The length of fixed segment 201.

It is known that the normal tongue extension length of the human body is 2-3cm, so when the patient can reach this length, the spring can be replaced with a stronger spring to increase the tongue extension training intensity. The scale on the caliper 20 can mark the tongue extension length each time, which is convenient for the patient to observe in time during the training process and record after the training to increase the training intensity every day.
