Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and in particular relates to an oral stimulation opener. Background Art

[0002] Elderly patients, especially those with Parkinson's disease, often experience increased muscle tone throughout the body, including in the facial, jaw, and throat muscles. Stiffness in the jaw muscles (such as the masseter and temporalis) can increase resistance to mouth opening, leading to slow movement and even pain. In severe cases, this can manifest as "gear-like stiffness" (a stuttering sensation when opening the mouth). The difficulty opening the mouth in elderly patients, especially those with Parkinson's disease, can hinder medical staff's ability to implement treatment.

[0003] In clinical practice, medical staff usually use a stimulation rod to stimulate the K-point in the patient's mouth to make the patient open his mouth. The K-point is located at the junction of the maxillary gum and the hard palate (approximately at the inner gum corresponding to the maxillary first molar), and is a special stimulation point in the mouth. The K-point area is innervated by the trigeminal nerve (the fifth cranial nerve). After stimulation, it can activate the brainstem reticular formation (regulate muscle tension) through neural reflexes; enhance the excitability of the brain's motor cortex, and promote the coordinated contraction and relaxation of oral muscles (such as the masseter and lateral pterygoid muscles), thereby improving difficulty in opening the mouth. However, today's stimulation rods and mouth openers are usually separated, and the degree of coordination between the two is low, which cannot effectively help medical staff stimulate patients to open their mouths.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Summary of the Invention

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0031] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0032] The present invention provides Figure 1 、 Figure 2 and Figure 3 As shown, an oral stimulation and opening device is used to stimulate the K point of the patient's oral cavity to make the patient open his mouth. The main structure of the present invention includes: an upper forceps arm 1, a lower forceps arm 2 and at least one stimulation rod 3; the upper forceps arm 1 and the lower forceps arm 2 are movably connected by a pin shaft 4, and the upper forceps arm 1 and the lower forceps arm 2 are both provided with a support portion 11 and a gripping portion 12. When the gripping portion 12 is grasped by hand and pulled closed with force, the support portion 11 opens in the opposite direction, thereby achieving the effect of supporting the patient's upper and lower teeth and helping the patient to open his mouth. The support portion 11 is used to support the patient's teeth, and the gripping portion 12 is used to be held by medical staff; the stimulation rod 3 is passed through the support portion 11 and the gripping portion 12, and the stimulation rod 3 extends along the extension direction of the upper forceps arm 1 or the lower forceps arm 2. The stimulation rod 3 can be retracted and retracted along the extension direction of the upper forceps arm 1 or the lower forceps arm 2;

[0033] Among them, a stimulation terminal 31 is provided on one end of the stimulation rod 3 located at the support part 11, and the stimulation terminal 31 passes through the end of the support part 11 away from the gripping part 12. A vibration generating device 311 is provided on the stimulation terminal 31, and the stimulation terminal 31 is used to stimulate the K point in the patient's mouth to stimulate the patient to open his mouth. It can be understood that vibration stimulation can suppress excessive muscle tension in the patient's mouth and indirectly improve the degree of mouth opening. Moderate vibration stimulation can regulate the coordination of muscles related to swallowing or pronunciation through neural reflexes. Moreover, vibration may distract the patient's attention from pain or tension, thereby reducing psychological mouth opening difficulties. Therefore, arranging a vibration generating device 311 on the stimulation terminal 31 can better stimulate the patient to open his mouth.

[0034] It should be noted that, clinically, medical staff usually use a stimulation rod 3 to stimulate the patient's oral K point to make the patient open his mouth. The K-point is located at the junction of the maxillary gum and the hard palate (approximately at the inner gum corresponding to the maxillary first molar), and is a special stimulation point in the oral cavity. The K-point area is innervated by the trigeminal nerve (the fifth cranial nerve). After stimulation, it can activate the brainstem reticular formation (regulate muscle tension) through nerve reflexes; enhance the excitability of the brain's motor cortex, and promote the coordinated contraction and relaxation of oral muscles (such as the masseter muscle and the lateral pterygoid muscle), thereby improving difficulty in opening the mouth. However, today's stimulation rod 3 and the mouth opener are usually separated, and the degree of coordination between the two is low, which cannot effectively help medical staff stimulate the patient to open his mouth.

[0035] When using the present invention, a medical professional holds the grip portion 12 of the mouth opener and then presses the end of the stimulation rod 3 away from the stimulation end 31, causing the stimulation end 31 to extend from one end of the mouth opener support portion 11 until the stimulation end 31 stimulates the K point in the patient's mouth and causes the patient to open their mouth. Finally, the support portion 11 is used to assist the patient in opening their mouth. During the operation, only one hand is required to complete the opening action, effectively improving the efficiency of the medical professional in assisting the patient in opening their mouth.

[0036] Further, such as Figure 3 As shown, the stimulation tip 31 is covered with a silicone layer 312, and a plurality of protrusions 313 are provided on the outer wall of the silicone layer 312. The protrusions 313 are integrally formed with the stimulation tip 31. It is understood that the protrusions 313 on the outer wall of the silicone layer 312 can increase the friction force for stimulating the K point in the patient's mouth, thereby better stimulating the patient to open his mouth.

[0037] Further, such as Figure 1 、 Figure 2 As shown, at least one of the upper forceps arm 1 and the lower forceps arm 2 is provided with at least one stimulation rod 3 , and the at least one stimulation rod 3 extends along the extension direction of the upper forceps arm 1 or the lower forceps arm 2 .

[0038] In other embodiments, the support parts 11 of the upper forceps arm 1 and the lower forceps arm 2 are both provided with stimulation ends 31, which can simultaneously stimulate the junction of the gums and hard palate on the left and right sides of the patient's upper jaw (approximately the inner gums corresponding to the maxillary first molar), which can better stimulate the patient to open his mouth.

[0039] Further, such as Figure 2 As shown, a mounting base 21 is provided on the gripping portion 12 of at least one of the upper clamp arm 1 and the lower clamp arm 2, and a through hole 22 is opened on the mounting base 21. The stimulation rod 3 includes: a telescopic operating rod 32 and a bendable extension section 33. The telescopic operating rod 32 is passed through the through hole 22, and the two ends of the bendable extension section 33 are respectively connected to the telescopic operating rod 32 and the stimulation end 31.

[0040] Further, such as Figure 1 、 Figure 2 As shown, an operating member 34 is provided at one end of the telescopic operating rod 32 away from the bendable extension 33. The operating member 34 is cylindrical in structure. The cylindrical structure of the operating member 34 facilitates the medical staff to rotate the telescopic operating rod 32. The top portion of the cylindrical structure also facilitates the pushing of the telescopic operating rod 32.

[0041] In some embodiments, the operating member 34 is provided with a battery and a switch member, and the switch member is used to start or shut down the vibration generating device 311, that is, to control the power supply of the vibration generating device 311. Among them, the wiring harness of the power supply can pass through the telescopic operating rod 32 and the bendable extension section 33 to connect the vibration generating device 311 on the stimulation terminal 31. Furthermore, the switch member is provided at the upper end of the operating member 34. When the medical staff pushes the upper end of the operating member 34 with a finger, the switch is turned on, and at the same time, the telescopic operating rod 32 pushes the stimulation terminal 31 out of the end of the support portion 11 through the bendable extension section 33. At this time, the vibration generating device 311 on the stimulation terminal 31 continues to vibrate and approaches the deepest K point in the patient's dentition, that is, the junction of the maxillary gum and the hard palate (approximately at the inner gum corresponding to the maxillary first molar). In this way, the technical effect of stimulating the patient's K point and causing the patient to actively open his mouth is achieved.

[0042] Further, such as Figure 2 As shown, the operating member 34 is provided with an abutting portion 341, and the telescopic operating rod 32 is sleeved with a spiral elastic member 35. Figure 2 As shown, two ends of the spiral elastic member 35 abut against the mounting base 21 and the abutting portion 341 respectively, and the elastic member is used to make the telescopic operating rod 32 extend from the through hole 22 .

[0043] It is understandable that the telescopic operating rod 32 has a telescopic state, and the two ends of the spiral elastic member 35 are respectively in contact with the mounting base 21 and the abutment portion 341. In the absence of an external force, the telescopic operating rod 32 can be in an extended state (at this time, the stimulation terminal 31 retracts to the end of the support portion 11). Therefore, in the process of assisting the patient to open the mouth, the medical staff only needs to control the thrust of one finger to control the depth of the telescopic operating rod 32, and then control the extension stroke of the stimulation terminal 31 until the stimulation terminal 31 stimulates the patient to actively open the mouth. When the opening stimulation process is completed, the medical staff removes the finger that originally pushed the telescopic operating rod 32. The telescopic operating rod 32 will automatically extend from the mounting base 21 under the elastic force of the spiral elastic member 35. At this time, the stimulation terminal 31 retreats to the end of the support portion 11, thereby preventing the stimulation terminal 31 from continuously stimulating the patient's K point.

[0044] Further, such as Figure 3 As shown, the stimulation terminal 31 is provided with a bending section, and the bending angle of the bending section is less than 90°. In this embodiment, the bending angle of the bending section is configured as a, that is, the bending angle of the bending section a is less than 90°.

[0045] It is understood that the bend section can cause the stimulation terminal 31 to extend in a direction that deviates from the axis of the flexible extension section 33. When medical personnel slowly rotate the operating member 34 on the telescopic operating rod 32, the flexible extension section 33 can drive the bend section and the stimulation terminal 31 to flip around the axis of the flexible extension section 33. This allows the stimulation terminal 31 to stimulate a wider range of tissue areas in the patient's mouth. This can help medical personnel better calibrate the direction of the stimulation terminal 31 and improve the stimulation effect and effectiveness of the K point in the patient's mouth.

[0046] Specifically, in some embodiments, the support portion 11 of the upper forceps arm 1 and the lower forceps arm 2 are both configured as a semicircular arc structure, and the semicircular arc structure matches the shape of the patient's dentition. In this way, the supporting force of the support portion 11 can be evenly distributed to the teeth on the patient's dentition, avoiding excessive concentration of the supporting force and causing damage to the patient's teeth. Furthermore, the bendable extension section 33 extends along the side wall of the semicircular arc structure, and the stimulation terminal 31 extends from the end of the semicircular arc structure. This allows the stimulation terminal 31 to touch the deepest K point in the patient's dentition, that is, the junction of the maxillary gum and the hard palate (approximately at the inner gum corresponding to the maxillary first molar).

[0047] Further, such as Figure 1 、 Figure 2As shown, at least one of the upper clamp arm 1 and the lower clamp arm 2 is provided with a plurality of limiting sleeves 13. The limiting sleeves 13 are arranged at intervals along the extension direction of the upper clamp arm 1 or the lower clamp arm 2. The limiting sleeves 13 are used to pass through the stimulation rod 3. It is understood that the limiting sleeves 13 can cover the flexible extension section 33 on the stimulation rod 3. The flexible extension section 33 can extend along the position where the limiting sleeves 13 are provided. This prevents the flexible extension section 33 from being twisted unexpectedly and affecting the extension and retraction of the stimulation terminal 31.

[0048] Further, such as Figure 1 、 Figure 2 As shown, a limiting bolt 121 is screwed onto the gripping portion 12 on the upper clamp arm 1, and the limiting bolt 121 extends toward the gripping portion 12 on the lower clamp arm 2. The extending direction of the limiting bolt 121 is perpendicular to the extending direction of the gripping portion 12, and the limiting bolt 121 is used to support the expansion angle of the upper clamp arm 1 and the lower clamp arm 2.

[0049] It is understood that after the grip portion 12 is grasped and forcefully pulled closed, to maintain the expanded angle of the support portion 11, the medical staff can rotate the limit bolt 121, causing the limit bolt 121 to continue to screw into the upper clamp arm 1 until the end of the limit bolt 121 abuts against the lower clamp arm 2. The limit bolt 121 supports the expanded angle of the upper and lower clamp arms 1 and 2, eliminating the need for the medical staff to constantly hold the grip end of the mouth opener. This facilitates the medical staff's subsequent oral care and reduces their workload.

[0050] Furthermore, a buffer rubber layer is provided on both the support portion 11 and the grip portion 12 .

[0051] It is understood that a cushioning rubber layer is provided on both the support portion 11 and the grip portion 12. The cushioning rubber layer on the grip portion 12 can cushion the pressure between the medical professional's palm and the grip portion 12, enhancing the grip feel when the medical professional grips the grip portion 12. Furthermore, the cushioning rubber layer on the support portion 11 can cushion the pressure between the patient's upper and lower dentition and the support portion 11, preventing excessive pressure from the support portion 11 on the patient's upper and lower dentition, which could damage the patient's teeth.

[0052] In summary, the present application provides an oral stimulating mouth opener. When in use, the medical staff holds the grip portion 12 of the mouth opener and then presses the end of the stimulation rod 3 away from the stimulation end 31, causing the stimulation end 31 to extend from one end of the mouth opener support portion 11 until the stimulation end 31 stimulates the K point in the patient's mouth and causes the patient to open his mouth. Finally, the support portion 11 assists the patient in opening his mouth. During operation, only one hand is required to complete the opening action, effectively improving the efficiency of the medical staff in assisting the patient in opening his mouth.

[0053] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
