Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an auxiliary tool used for oral joint irrigation and flushing. Background Art

[0002] Temporomandibular joint disorder is a common oral and maxillofacial disease, and is listed by the World Health Organization as the fourth oral epidemic affecting human health. It is a musculoskeletal disease that affects the temporomandibular joint, masticatory muscles and their related accessory structures. It is mainly manifested as pain in the temporomandibular joint area, limited mouth opening, temporomandibular joint clicking, masticatory muscle pain and mandibular movement disorders, etc. It is one of the common causes of oral and maxillofacial pain. The temporomandibular joint is a sliding joint, and synovial fluid is its important lubricant. When the synovial fluid is reduced or disappears, the joint will show "rusty" symptoms. Therefore, physiological saline is perfused into the temporomandibular joint to flush the inflammation, and hyaluronic acid gel or medical chitosan is injected as a "lubricant". Joint cavity lavage is a clinical treatment method between surgical treatment and non-surgical treatment, and is also one of the current methods for treating temporomandibular joint diseases.

[0003] For this type of oral disease, the patient's mouth needs to be irrigated and rinsed. During the current rinse process, the patient is required to open his mouth. For patients who have difficulty opening their mouths, medical staff are required to cooperate and assist, which invisibly reduces the work efficiency of medical staff. Utility Model Content

[0032] To make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] For oral diseases such as temporomandibular joint disorder, the patient's oral cavity needs to be irrigated and rinsed. However, during the current rinsing process, the patient needs to open his mouth. For patients who have difficulty opening their mouths, medical staff are required to assist, which invisibly reduces the work efficiency of medical staff. In response to the above technical problems, the utility model provides an auxiliary tool for oral joint irrigating and flushing. During medical care, it can assist patients in shaping the opening angle of their oral cavity. The overall structural design is simple. The technical solution of the utility model is described in detail below in conjunction with specific examples.

[0035] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model relates to an auxiliary tool for oral joint irrigation and flushing, comprising a first limiter 1, a second limiter 2 and a limiter assembly 3, wherein the first limiter 1 and the second limiter 2 are stacked, and one end of the first limiter 1 is hinged to the second limiter 2. The limiter assembly 3 is arranged on the first limiter 1, and when the patient's lower teeth and upper teeth bite the first limiter 1 and the second limiter 2 respectively, the limiter assembly 3 limits the first limiter 1 and the second limiter 2 from rotating under the action of the bite force.

[0036] Illustratively, medical staff can use this auxiliary tool to assist patients in cooperating in opening their mouths. When in use, the hinged end of the auxiliary tool is placed into the patient's mouth, and the first limiter 1 is placed on the platform formed by the lower teeth on one side, and the second limiter 2 corresponds to the contact with the upper teeth above. After the patient completes the opening action, the limiter assembly 3 is adjusted to limit the rotation of the first limiter 1 and the second limiter 2 under the action of the bite force, which can assist the patient in shaping the opening angle of the mouth. The overall structural design is simple and can improve the work efficiency of medical staff.

[0037] In addition, the overall material of this auxiliary tool can be selected as plastic, which can greatly reduce the manufacturing cost, enabling the auxiliary tool to be used as a disposable item. After use, it can be directly discarded, eliminating the cleaning and disinfection work for medical staff and further improving the work efficiency of medical staff.

[0038] In one embodiment, specifically, both the first limiting member 1 and the second limiting member 2 are in the shape of a ruler. In order to prevent the edges and corners of the components from accidentally scratching the patient's oral cavity, rounded corners are provided at the hinged connection ends of the first limiting member 1 and the second limiting member 2.

[0039] In this embodiment, a scale 21 is provided on the second limiting member 2, and the 0-degree line of the scale 21 is located at the end away from the hinged connection end.

[0040] It should be noted that the ruler-shaped setting in combination with the scale 21 enables this tool to preliminarily measure the patient's mouth opening, further improving the practicality of this auxiliary tool.

[0041] In one embodiment, the overall structure of the limiting component 3 is further refined. The limiting component 3 includes a slider 31, and the slider 31 is slidably connected to the first limiting member 1.

[0042] The slider 31 protrudes between the first limiting member 1 and the second limiting member 2. When the patient bites the first limiting member 1 and the second limiting member 2, the slider 31 contacts the bottom of the second limiting member 2, and the slider 31 restricts the rotation of the first limiting member 1 and the second limiting member 2 under the action of the biting force.

[0043] The slider 31 slides along the length direction of the first limiting member 1 as a whole. When the patient's oral cavity opens to the required angle, the medical staff slides the slider 31 to the bottom of the second limiting member 2. At this time, the biting force of the patient's oral cavity causes the first limiting member 1 and the second limiting member 2 to rotate relative to each other, making the first limiting member 1 and the second limiting member 2 squeeze the slider 31. During the squeezing process, due to the downward squeezing component force of the second limiting member 2, the slider 31 can be restricted and positioned and will not be pushed by the biting force.

[0044] In this embodiment, more preferably, one end of the first limiting member 1 extends outward to provide a rotation range for the slider 31 to slide away from the second limiting member 2.

[0045] Specifically, during daily storage, the slider 31 can slide to the end of the first limiting member 1. At this time, the slider 31 slides out of the rotation range of the second limiting member 2, so the second limiting member 2 can rotate to a state where it overlaps with the first limiting member 1, enabling this auxiliary tool to have the effect of being convenient for storage.

[0046] Refer to Figure 4As shown, a chute 32 is formed on the first limiting member 1, and the slider 31 has a connecting portion which is slidably connected to the chute 32.

[0047] More preferably, in order to improve the limiting stability of the slider 31, a rubber strip 33 is provided on the first limiting member 1, and the bottom of the slider 31 presses against the rubber strip 33. The rubber strip 33 can increase the sliding friction of the slider 31. Even if the material of the first limiting member 1 makes the sliding of the slider 31 relatively smooth, with the assistance of the rubber strip 33, the limiting stability of the slider 31 can still be increased.

[0048] In an embodiment, the hinge structure of the first limiting member 1 and the second limiting member 2 is further refined. Among them, a hinge member 4 is provided on the first limiting member 1. The hinge member 4 includes a rotating shaft and bosses integrally provided at both ends of the rotating shaft. The first limiting member 1 and the second limiting member 2 are respectively hinged to the two bosses.

[0049] In this embodiment, more preferably, a torsion spring 5 is provided on the rotating shaft. One end of the torsion spring 5 is connected to the first limiting member 1, and the other end is connected to the second limiting member 2. The elastic force of the torsion spring 5 drives the first limiting member 1 and the second limiting member 2 to rotate and open.

[0050] Exemplarily, after the auxiliary tool is placed into the patient's oral cavity, the elastic force of the torsion spring 5 can cause the first limiting member 1 and the second limiting member 2 to rotate and open. For patients who have difficulty in performing some opening actions, this auxiliary tool can also play a role in assisting them to open. In addition, the elastic force of the torsion spring 5 can also make the first limiting member 1 and the second limiting member 2 keep in contact with the upper teeth and the lower teeth during the process of the patient opening the oral cavity. After the patient opens to the appropriate position, it is convenient for the medical staff to adjust the slider 31 to position it, improving the flexibility of use of this auxiliary tool.

[0051] Among them, referring to Figure 3 As shown, one side of the slider 31 is attached to the edge of the first limiting member 1. In the storage state, the second limiting member 2 can rotate to a state of overlapping with the first limiting member 1. Then, the slider 31 is pushed to enter the rotation range of the second limiting member 2 again. At this time, the slider 31 can limit the second limiting member 2 from rotating and opening under the action of the elastic force of the torsion spring 5, making this auxiliary tool have the effect of being convenient for storage.

[0052] In an embodiment, a clamping block 6 is provided at the bottom of the first limiting member 1 for the patient's lower teeth to abut and position.

[0053] Specific implementation process:

[0054] Medical staff can use this auxiliary tool to assist patients in cooperating to open their mouths. When in use, put the hinged connection end of this auxiliary tool into the patient's oral cavity, and place the first limiting member 1 on the platform formed by the lower teeth on one side. During the insertion process, make the side of the clamping block 6 close to the hinged connection end closely adhere to the patient's lower teeth for positioning, and the second limiting member 2 correspondingly contacts the upper teeth above. The elastic force of the torsion spring 5 enables the first limiting member 1 and the second limiting member 2 to keep in contact with the upper teeth and the lower teeth during the process of the patient opening the mouth. After the patient opens the mouth in place, the medical staff slides the slider 31 to the bottom of the second limiting member 2. At this time, the biting force of the patient's oral cavity causes the first limiting member 1 and the second limiting member 2 to rotate relative to each other, making the first limiting member 1 and the second limiting member 2 squeeze the slider 31. With the auxiliary positioning of the rubber strip 33, the slider 31 can be stably located between the first limiting member 1 and the second limiting member 2 to assist the patient in shaping the opening angle of the oral cavity. After the positioning of the first limiting member 1 and the second limiting member 2 is completed, the medical staff can guide the patient to take this auxiliary tool by themselves. When taking it, only need to keep the clamping block 6 closely adhering to the lower teeth to maintain the positioning effect of this tool, and the medical staff can free their hands to perform subsequent nursing operations.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
