Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an auxiliary opening device for oral examination and treatment. Background Art

[0002] The lingual retractor is a commonly used opening device in oral examination and treatment. The lingual retractor usually consists of a lip plate structure and a support structure. The support structure can drive the lip plate structure to support the patient's lips, enabling the separation of the patient's lips and teeth, which is convenient for medical staff to perform oral treatment on the patient. When the patient undergoes oral treatment, the patient's tongue is prone to random stretching and retracting, which easily causes the patient's tongue to accidentally touch the oral treatment instrument, resulting in damage to the patient's tongue by the oral treatment instrument. To avoid damage to the patient's tongue by the oral treatment instrument, a lingual retractor with a saliva suction structure has emerged on the market. Such a retractor has a tongue blocker added between two lip plates. The tongue blocker is usually a tubular structure sealed at one end. The two sides of the tongue blocker are clamped to the lip plates of the retractor through rib rods. During actual use, the patient's tongue tip needs to be inserted into the interior of the tubular structure. When the patient's tongue drives the tongue blocker to stretch and retract, the rib rods on both sides of the tongue blocker will generate a repulsive force on the patient's tongue, which can effectively prevent the patient's tongue from contacting the oral treatment instrument. At the same time, suction tubes are connected to both sides of the tongue blocker, and the discharge end of the suction tube is connected to an external pump. The pump can pump the saliva in the patient's oral cavity through the suction tube, which is convenient for medical staff to perform oral treatment on the patient;

[0003] When such a retractor is actually used, it can indeed solve the problem of random stretching and retracting of the patient's tongue. However, the retractor does not have much space for the tongue to move. When the patient's tongue is inserted into the tongue blocker, the edge of the tongue blocker is likely to cut the patient's tongue, which increases the risk of oral treatment for the patient. At the same time, the suction tube connected to the retractor is usually a common hose structure on the market, and no other structure is provided at the part where the suction tube contacts the patient's oral cavity. When the patient undergoes teeth cleaning or dental drilling, the sand-like substances in the patient's oral cavity cannot be discharged through the suction tube in a timely manner, and the remaining sand-like substances are likely to increase the discomfort of the patient's oral cavity. At this time, the patient will reject oral treatment. Therefore, we propose an auxiliary opening device for oral examination and treatment. Summary of the Invention

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of 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.

[0035] Embodiment 1: Please refer to Figure 1-8 , the present invention provides a technical solution: An auxiliary opening device in oral examination and treatment includes a damping rib rod 1 and a lip baffle structure connected to the damping rib rod 1, and further includes:

[0036] The supporting rib rod 4 is connected to the inner side of the lip blocking structure. The supporting rib rod 4 is connected to the movable blocking rod 7 through a telescopic assembly. The supporting rib rod 4 can support the movable blocking rod 7, so that the movable blocking rod 7 can cooperate with the arc-shaped tongue blocking plate 9 to block the tongue of the patient's oral cavity. The arc-shaped tongue blocking plate 9 is distributed between the two movable blocking rods 7. The movable blocking rod 7 and the arc-shaped tongue blocking plate 9 can form a U-shaped structure, which can realize the stable blocking of the tongue of the patient's oral cavity by the movable blocking rod 7 and the arc-shaped tongue blocking plate 9;

[0037] During actual use, medical staff can place the lip guard 3 inside the patient's mouth. The lip guard 3 can block the patient's lips and separate the patient's lips and teeth, which can facilitate medical staff to treat the teeth inside the patient's mouth. At the same time, the arc-shaped tongue guard 9 can block the tongue inside the patient's mouth to prevent the patient's tongue from contacting with the teeth and treatment instruments.

[0038] Example 2: Please refer to Figure 1-10 , the present invention provides a technical solution:

[0039] A connecting hose 22 is provided on the movable baffle rod 7 and the arc-shaped baffle plate 9. The movable baffle rod 7 and the arc-shaped baffle plate 9 are both hollow structures. A through hole 20 is provided on the movable baffle rod 7 and the arc-shaped baffle plate 9. The inner cavity of the movable baffle rod 7 is connected to the inner cavity of the arc-shaped baffle plate 9. The end of the movable baffle rod 7 away from the arc-shaped baffle plate 9 is connected to the baffle lip structure through a telescopic hose 11, so that the inner cavity of the baffle lip structure can be connected to the inner cavity of the movable baffle rod 7 and the arc-shaped baffle plate 9, so that the saliva inside the movable baffle rod 7 and the arc-shaped baffle plate 9 can enter the inner cavity of the baffle lip structure.

[0040] The connecting hose 22 is connected to a storage chamber 17, and the lower part of the storage chamber 17 is detachably connected to the collecting chamber 16. The inner cavity of the storage chamber 17 is communicated with the inner cavity of the collecting chamber 16, and the storage chamber 17 can drive saliva and sand-like objects into the interior of the collecting chamber 16. The sand-like objects proposed in this document are sand-like objects that are separated from the patient's teeth during tooth drilling and scaling treatments. The upper part of the collecting chamber 16 near the storage chamber 17 is fixedly connected to a filter baffle 23, and the filter baffle 23 can divert the sand-like objects. The diverted sand-like objects can be collected in the collecting chamber 16. At the same time, the filter baffle 23 can play a role in placing the filter plate 21. When the sand-like objects on the filter baffle 23 enter the interior of the collecting chamber 16, the water flow rate in the collecting chamber 16 is slow. At this time, the sand-like objects in the collecting chamber 16 are not easy to float up, so the separation of the sand-like objects in the collecting chamber 16 can be avoided. A water inlet hole 27 is provided at the position opposite to the connecting hose 22. The water inlet hole 27 can drive saliva and sand to contact the filter plate 21. The filter plate 21 can filter the sand in the saliva, so that the sand can be stored inside the storage chamber 17. An external rectangular plate 15 is fixedly connected to one side of the storage chamber 17. A through rod 24 is fixedly connected to the external rectangular plate 15. The through rod 24 penetrates the through opening 20. A connecting ball head 25 is fixedly connected to the end of the through rod 24 facing away from the external rectangular plate 15. The through rod 24 can slide on the movable baffle rod 7 and the arc-shaped tongue baffle plate 9. At this time, the use position of the storage chamber 17 can be adjusted. It should be supplemented that the movable baffle rod 7 and the arc-shaped tongue baffle plate 9 are connected to the position where the through rod 24 penetrates by a sealing ring. The sealing ring can seal the opening of the movable baffle rod 7 and the arc-shaped tongue baffle plate 9 to prevent saliva from flowing out of the movable baffle rod 7 and the arc-shaped tongue baffle plate 9.

[0041] A guide portion 18 is provided on the outer edge of the water inlet hole 27, which can expand the storage range of the water inlet hole 27, so that saliva and sand in the oral cavity can quickly enter the interior of the storage cavity 17. The lower end of the filter plate 21 is in contact with the filter baffle 23, and the connecting hose 22 is elastic. When the through rod 24 slides on the movable baffle 7 and the arc-shaped tongue baffle plate 9, the connecting hose 22 can be extended and retracted. Since the connecting hose 22 is elastic, the repulsive force generated by the connecting hose 22 can drive the through rod 24 to reset.

[0042] The arc-shaped tongue stopper 9 is in an arc shape, and the movable stopper 7 is bent toward the arc-shaped tongue stopper 9 near the arc-shaped tongue stopper 9. Both ends of the arc-shaped tongue stopper 9 are fixedly connected with connecting blocks 8. The arc-shaped tongue stopper 9 cooperates with the connecting block 8 and the movable stopper 7 to form a U-shaped structure, which can achieve a better fit between the patient's tongue and the arc-shaped tongue stopper 9, the connecting block 8 and the movable stopper 7.

[0043] The connecting block 8 is a hollow structure, and the inner cavity of the connecting block 8 is connected with the inner cavity of the rectangular rubber hose 14 and the arc-shaped tongue baffle 9. The rectangular rubber hose 14 is elastic. The movable baffle rod 7 and the arc-shaped tongue baffle 9 are provided with a water inlet 19 near the through-hole 20. The movable baffle rod 7 and the arc-shaped tongue baffle 9 are connected with the connecting hose 22 through the water inlet 19. When the saliva and sand in the patient's mouth enter the storage cavity 17, the saliva filtered by the filter plate 21 can enter the movable baffle rod 7 and the arc-shaped tongue baffle 9 through the connecting hose 22.

[0044] During actual use, the external discharge pipe 26 is connected to the external pump through an external water pipe. When the external pump is working, the external pump can discharge saliva inside the movable baffle rod 7 and the arc-shaped tongue baffle plate 9 through the external water pipe. At this time, the interior of the movable baffle rod 7 and the arc-shaped tongue baffle plate 9 is in a negative pressure state, and the saliva and sand inside the patient's mouth can enter the storage chamber 17 through the water inlet hole 27. The filter plate 21 can filter the sand in the saliva. It should be added that the working mode of the external pump is intermittent. When the external pump is not working, the sand filtered by the filter plate 21 can be filtered by gravity. The saliva passes through the lower filter baffle 23 and is collected inside the collection chamber 16. When the external pump is working, the saliva filtered by the filter plate 21 can pass through the connecting hose 22 and enter the movable baffle rod 7 and the arc-shaped tongue baffle plate 9. Since the inner cavities of the movable baffle rod 7 and the arc-shaped tongue baffle plate 9 are connected, eventually, the saliva inside the movable baffle rod 7 and the arc-shaped tongue baffle plate 9 can enter the first side plate 2 and the second side plate 13 through the telescopic hose 11. Subsequently, the saliva inside the first side plate 2 and the second side plate 13 can enter the external water pipe through the external discharge pipe 26, thereby realizing that the device drives the discharge of saliva from the patient's mouth.

[0045] Example 3: Please refer to Figure 1-8 , the present invention provides a technical solution:

[0046] The telescopic assembly includes a fixed end block 6 fixedly connected to the movable stop rod 7, a sliding rod 10 fixedly connected to the fixed end block 6, the sliding rod 10 penetrates the supporting rib rod 4, when the sliding rod 10 slides on the supporting rib rod 4, the use position of the movable stop rod 7 can be adjusted, the end of the sliding rod 10 away from the fixed end block 6 is fixedly connected to the end block 5, an extrusion spring 12 is arranged between the end block 5 and the supporting rib rod 4, the extrusion spring 12 is sleeved with the sliding rod 10, the end block 5 can compress the extrusion spring 12, and the extrusion spring 12 can be prevented from separating from the sliding rod 10.

[0047] The supporting rib rod 4 is a hollow structure, and the inner cavity of the supporting rib rod 4 is connected with the inner cavity of the telescopic hose 11 . The telescopic hose 11 is elastic and can drive the saliva inside the movable blocking rod 7 to transport to the first side plate 2 and the second side plate 13 .

[0048] The lip barrier structure includes a first side plate 2 and a second side plate 13. The first side plate 2 and the second side plate 13 are both L-shaped hollow structures. The first side plate 2 and the second side plate 13 are relatively distributed. The first side plate 2 and the second side plate 13 can block the muscles of the patient's cheeks and can also drain saliva inside the movable barrier rod 7.

[0049] The inner cavities of the first side plate 2 and the second side plate 13 are connected to the inner cavities of the supporting rib rod 4. The end of the first side plate 2 facing away from the supporting rib rod 4 is rotatably connected to the damping rib rod 1. The first side plate 2 is fixedly connected to the external row pipe 26 near the damping rib rod 1. The damping rib rod 1 can support the first side plate 2 and the second side plate 13, so that the first side plate 2 and the second side plate 13 can be firmly placed inside the patient's mouth.

[0050] The top and bottom surfaces of the first side plate 2 are fixedly connected with lip shields 3, which are arc-shaped structures. The arc-shaped tongue shields 9 are located between the four lip shields 3. The structure of the lip shields 3 is the same as that of the lip shields in the existing tongue opening device. The lip shields 3 can cover the lips of the patient, so as to separate the lips and teeth of the patient.

[0051] During actual use, the medical staff inserts the lip guard 3 into the patient's oral cavity, and the lip guard 3 can cover the patient's lips, so that the patient's lips and teeth can be separated. When the patient's tongue presses against the arc-shaped tongue guard 9, the arc-shaped tongue guard 9 can drive the sliding plug rod 10 to slide on the supporting rib rod 4. At this time, the extrusion spring 12 works with accumulated force, so that the position of the arc-shaped tongue guard 9 can be adjusted. At the same time, the arc-shaped tongue guard 9 can also rotate around the rectangular hose 14 as the center, and the rectangular hose 14 can also generate repulsive force. The repulsive force generated by the rectangular hose 14 can drive the arc-shaped tongue guard 9 to reset, so that the patient's tongue can move in a small range.

[0052] Example 4: Please refer to Figure 1-10 , the present invention provides a technical solution:

[0053] When the patient's tongue wants to lick his teeth, the patient's tongue can squeeze the connecting ball head 25. At this time, the use position of the storage chamber 17 can be adjusted, and the storage chamber 17 can be close to the teeth. When the external pump is working intermittently, the storage chamber 17 can collect saliva and sand around the teeth through the water inlet hole 27, so that the storage chamber 17 can accurately collect saliva and sand. When replenishment is needed, the storage chamber 17 cannot abut against the patient's teeth, thereby realizing that the device meets humanized needs.
