Description

Technical Field

[0001] This utility model relates to the field of training tools, specifically to an mouth-opening training tool with measurement and recording functions. Background Technology

[0002] Currently, radiotherapy is the preferred treatment for head and neck malignant tumors. Although new technologies are becoming increasingly mature and reducing the incidence of complications, the temporomandibular joint and masticatory muscles undergo degenerative changes and fibrosis due to the effects of radiation, leading to muscle atrophy and joint stiffness, resulting in temporomandibular joint dysfunction. Initially, this manifests as tightness and pain in the temporomandibular joint when opening the mouth. If it continues to progress, temporomandibular joint movement becomes restricted, the distance between the incisors gradually decreases, speech becomes slurred, and in severe cases, trismus and difficulty eating occur.

[0003] Chinese utility model CN219662209U describes a mouth-opening training device after temporomandibular joint surgery. It includes an adjustment mechanism for the mouth-opening training device. The principle is to rotate the knob to compress the spring, causing the spring to rebound and push the clamp to close, thereby opening one end of the clamp to support the patient's mouth and achieve the purpose of training mouth opening. The force of the spring rebound can be adjusted by continuously adjusting the position of the knob.

[0004] However, existing devices lack measurement and recording functions, making it impossible to monitor training progress and effectiveness in real time. Furthermore, the adjusting rod's instability due to sliding within the groove as the clamps open and close is also problematic, and the tip of the hinged rod can easily poke the patient's face, resulting in poor practicality. Therefore, an adjustable mouth-opening trainer with measurement functions was designed to address these issues. Utility Model Content

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] Currently, radiotherapy is the preferred treatment for head and neck malignant tumors. Although new technologies are becoming increasingly mature and reducing the incidence of complications, the temporomandibular joint and masticatory muscles undergo degenerative changes and fibrosis due to the effects of radiation, leading to muscle atrophy and joint stiffness, resulting in temporomandibular joint dysfunction. Initially, this manifests as tightness and pain in the temporomandibular joint when opening the mouth. If it continues to progress, temporomandibular joint movement becomes restricted, the distance between the incisors gradually decreases, speech becomes slurred, and in severe cases, trismus and difficulty eating occur.

[0032] In related technologies, rotating a knob compresses a spring, causing the spring to rebound and close the clamp, thus opening one end of the clamp to support the patient's mouth and train mouth opening. The spring's rebound force can be adjusted by continuously adjusting the position of the knob. However, existing devices lack measurement and recording functions, making it impossible to monitor the training progress and effectiveness in real time. Furthermore, the adjusting rod slides within the groove while the clamp is opening and closing, which is unstable, and the tip of the hinged rod can easily poke the patient's face, resulting in poor practicality.

[0033] To address some of the problems in related technologies, this application provides an oral opening training tool with measurement and recording functions. When training a patient's oral cavity, the tray 11 is first placed in the patient's mouth, contacting the patient's teeth. The threaded rod 25 is then rotated, connecting it to the threaded block 26. The threaded block 26 is restricted from rotation by the groove 24. As the threaded rod 25 rotates, it drives the threaded block 26 upwards. The two ends of the threaded block 26 are connected to the ring 22, causing the ring 22 to slide upwards on the column 13, simultaneously pushing the spring 23 and the frame 21 upwards. The spring 23 is adjusted to a suitable rebound force. The patient can then train the degree of oral cavity opening and closing by opening and closing their mouth. During training, the position of the frame 21 on the column 13 can be observed, and the width of the patient's oral cavity opening can be measured using the observation and measurement table 27 and recorded in real time to facilitate understanding of the patient's training effect.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] This application provides an oral opening training tool with measurement and recording functions, comprising: a support plate 11 with a base plate 12 at one end; a column 13 disposed on the top of the base plate 12; an adjustment assembly 2 disposed on the base plate 12, the adjustment assembly 2 comprising: a frame 21 sleeved on the column 13 and connected to the support plate 11; a ring 22 sleeved on the column 13; a spring 23 sleeved on the outside of the column 13 and connected at both ends to the frame 21 and the ring 22; a groove 24 formed inside the column 13; a threaded rod 25 with its bottom penetrating through the top of the column 13 and inserted into the groove 24, and rotatably connected to the column 13; a threaded block 26 slidably disposed inside the groove 24 and penetrated by the threaded rod 25, threadedly connected to the threaded rod 25, and fixedly connected at both ends to the inner sidewall of the ring 22; and a measuring gauge 27 disposed on the front surface of the column 13.

[0036] When training a patient's oral cavity, the tray 11 is first placed in the patient's mouth, contacting the patient's teeth. The threaded rod 25 is then rotated, connecting it to the threaded block 26. The threaded block 26 is restricted from rotation by the groove 24. As the threaded rod 25 rotates, it drives the threaded block 26 upwards. The two ends of the threaded block 26 are connected to the ring 22, causing the ring 22 to slide upwards on the column 13, simultaneously pushing the spring 23 and frame 21 upwards. The spring 23 is adjusted to a suitable rebound force. The patient can then train their oral cavity opening and closing by opening and closing their mouth. During training, the position of the frame 21 on the column 13 can be observed, and the width of the patient's open mouth can be measured using the observation and measurement table 27 and recorded in real time to understand the patient's training effect.

[0037] In some embodiments, the adjustment assembly 2 further includes a torque 28 disposed at the top of the threaded rod 25.

[0038] When in use, the design of the knob 28 makes it easy to grip and control the rotation of the threaded rod 25. At the same time, the groove on the knob 28 can increase the friction when rotating.

[0039] In some embodiments, the adjustment component 2 further includes a retaining ring 29 fixedly sleeved on the outer side wall of the top end of the column 13.

[0040] The design of the retaining ring 29 can prevent the frame 21 from detaching from the column 13 and limit the movement trajectory of the frame 21.

[0041] In some embodiments, the adjustment component 2 further includes a rubber protrusion 291 disposed on the outer side wall of the support plate 11.

[0042] The design of the rubber protrusions 291 during use makes the tray 11 less likely to detach from the teeth and allows it to stay better inside the oral cavity.

[0043] In some embodiments, the adjustment assembly 2 further includes: the bottom end of the upright 292 passes through the upper support plate 11 and is connected to the lower support plate 11.

[0044] The design of the upright 292 during use allows the tray 11 to move stably up and down without rotating.

[0045] In some embodiments, the tray 11 is provided with a saliva-absorbing assembly 3, which includes: an absorbent sponge 31 disposed at one end of the tray 11; a connecting plate 32 disposed on one side of the absorbent sponge 31; a positioning hole 33 formed on the tray 11 and the connecting plate 32; and a pin 34 inserted into the interior of the positioning hole 33 at its bottom end.

[0046] During use, the patient's mouth will secrete saliva during the training process. The absorbent sponge 31 can absorb the saliva. After the training is over, the pin 34 can be pulled out from the positioning hole 33 to release the restriction on the connecting plate 32, so that the connecting plate 32 can be separated from the support plate 11, and the absorbent sponge 31 can be removed.

[0047] In some embodiments, the saliva suction assembly 3 further includes a cone 35 disposed at the bottom of the pin 34.

[0048] The design of the cone 35 makes it easier for the pin 34 to be inserted into the positioning hole 33 during use.

[0049] In some embodiments, the saliva suction assembly 3 further includes a magnetic ring 36 disposed on the connecting plate 32 and the pin 34, and magnetically attracted to each other.

[0050] When in use, the magnetic ring 36 is designed so that when the pin 34 is inserted into the positioning hole 33, the magnetic ring 36 attracts the pin and makes it difficult for the pin to detach from the positioning hole 33, thus stabilizing the position of the pin 34.
