Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multifunctional safety mouth mirror. Background Technology

[0002] Oral mirrors play a vital role in oral medicine. Through them, doctors can clearly observe various parts of the oral cavity, including teeth, gums, and oral mucosa, which helps them to discover potential oral problems.

[0003] During tooth extractions, tooth preparation, or other treatments involving the manipulation of tooth structure, there is a risk of tooth fragments or small pieces being ejected into the patient's mouth and subsequently swallowed. Similarly, in complex dental procedures, limited visibility or operating space can also lead to accidental swallowing of tooth tissue. Therefore, it is necessary to design a mouth mirror to assist dentists in reducing the occurrence of tooth tissue swallowing. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a multifunctional safety mouth mirror. This invention can prevent tooth tissue from falling into the patient's mouth and causing accidental swallowing.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A multifunctional safety mouthpiece includes a mouthpiece lens and a mouthpiece blade, and a mouthpiece handle connected to the mouthpiece lens at one end. The mouthpiece blade is mounted on the mouthpiece lens. Both the mouthpiece lens and the mouthpiece handle are hollow and interconnected to form a cavity. A rib that can move along the length of the mouthpiece handle is provided inside the cavity. The rib is connected to several tension ropes in a tree-like manner inside the mouthpiece lens. Support rods are provided on both sides of the mouthpiece lens. The tension ropes pass through the side walls of the mouthpiece lens and are connected to the support rods. Several springs are also connected between the mouthpiece lens and the support rods, and the springs are sleeved on the tension ropes. Several nets are provided between the mouthpiece lens and the support rods.

[0007] In the above technical solution, since several nets are provided between the support rod and the mouthpiece, the spring can move the support rod away from the mouthpiece, thus keeping the nets open. During oral treatment, the open nets can prevent tooth tissue from being swallowed by the patient. By moving the keel, the tension rope is pulled, which in turn moves the support rod closer to the mouthpiece, thus closing the nets. When the nets are not needed, closing them facilitates oral examination operations.

[0008] Furthermore, the nozzle is provided with a first guide groove and several second guide grooves, the second guide grooves are connected to the first guide groove, the keel is located in the first guide groove, and the tensioning rope is located in the second guide groove.

[0009] The first guide groove defines the direction of movement of the keel, and the second guide groove defines the direction of movement of the tension rope.

[0010] Furthermore, the lower surface of the mouth lens abuts against the upper surfaces of the first guide groove and the second guide groove. This contact between the lower surface of the mouth lens and the upper surfaces of the first and second guide grooves prevents the keel and the tension rope from deviating from the guide grooves during movement.

[0011] Furthermore, the first keel has a slider at the end furthest from the mouthpiece, and the slider is slidably connected to the mouthpiece handle. Movement of the keel is achieved by moving the slider.

[0012] Furthermore, a stop plate is provided on the slider, and a stop block is provided on one side of the mouth mirror handle, with the stop plate abutting against the stop block. The stop plate and stop block prevent the slider from moving. After the mesh bag is opened, the stop plate restricts the movement of the slider, thus keeping the opening range of the mesh bag fixed, facilitating oral treatment.

[0013] Furthermore, the second guide groove has a limiting step at its end away from the first guide groove. This limiting step provides a point of force for the spring.

[0014] Furthermore, a groove is provided on the side wall of the mouth mirror. The support rod can be housed in the groove. When the net is not needed, storing the support rod in the groove can reduce the volume of the mouth mirror and facilitate oral examination.

[0015] Furthermore, the support rod is covered with a scratch-resistant layer. This anti-slip layer prevents the support rod from scratching the patient's mouth.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. A spring allows the support rod to be moved away from the mouthpiece, keeping the net open. During dental treatment, the open net prevents tooth tissue from being swallowed by the patient. Moving the keel pulls the tension rope, which in turn moves the support rod closer to the mouthpiece, allowing the net to be closed. When the net is not needed, closing it facilitates dental examinations.

[0018] 2. The stop plate and stop block prevent the slider from moving. After the net bag is opened, the stop plate restricts the movement of the slider, thereby keeping the opening range of the net bag fixed and facilitating oral treatment.

[0019] 3. The groove can be used to store the support rod. When the mesh bag is not needed, storing the support rod in the groove can reduce the size of the mouth mirror and facilitate oral examination. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The following is combined Figures 1 to 9 The present invention provides a detailed description of a multifunctional safety mouth mirror through specific embodiments and application scenarios.

[0034] A multifunctional safety mouthpiece includes a mouthpiece lens 1 and a mouthpiece lens 12, and a mouthpiece handle 2 connected to the mouthpiece lens 1 at one end. The mouthpiece lens 12 is mounted on the mouthpiece lens 1. Both the mouthpiece lens 1 and the mouthpiece handle 2 are hollow and interconnected to form a cavity. A keel 3 that can move along the length of the mouthpiece handle 2 is provided in the cavity. The keel 3 is connected in a tree-like manner to several tension ropes 4 inside the mouthpiece lens 1. Support rods 5 are provided on both sides of the mouthpiece lens 1. The tension ropes 4 pass through the side wall of the mouthpiece lens 1 and are connected to the support rods 5. Several springs 15 are also connected between the mouthpiece lens 1 and the support rods 5. The springs 15 are sleeved on the tension ropes 4. Several nets 6 are provided between the mouthpiece lens 1 and the support rods 5.

[0035] Specifically, such as Figures 1 to 5As shown, the mouth mirror handle 2 includes a grip portion and a connecting portion, one end of which is fixedly connected to the mouth mirror 1. Both the mouth mirror 1 and the mouth mirror handle 2 are hollow and interconnected to form a cavity. The cavity in the mouth mirror handle 2 is channel-shaped, extending along the length of the mouth mirror handle 2, passing through the connecting portion and extending into the grip portion. A keel 3 is placed inside the cavity, with one end of the keel 3 located inside the mouth mirror 1 and the other end located inside the grip portion of the mouth mirror handle 2. Four tension ropes 4 are fixedly connected to the keel 3 inside the mouth mirror 1, and the four tension ropes 4 are symmetrically arranged on both sides of the keel 3 in a tree-like pattern. Support rods 5 are provided on both sides of the mouth mirror 1. The support rods 5 have an arc-shaped structure, and the arc matches the side arc of the mouth mirror 1, allowing the support rods 5 to fit against the side wall of the mouth mirror 1. One end of the tension rope 4 is fixedly connected to the keel 3, and the other end passes through the side wall of the mouthpiece 1 and is fixedly connected to the support rod 5. Moving the keel 3 moves the tension rope 4. A spring 15 is also connected between the mouthpiece 1 and the support rod 5, and the spring 15 is fitted onto the tension rope 4. Because the support rod 5 is hollow and made of lightweight material, the stiffness of the spring 15 can support the support rod 5 and keep it away from the mouthpiece 1. Moving the tension rope 4 brings the support rod 5 closer to the mouthpiece 1. A net 6 is also connected between the support rod 5 and the side wall of the mouthpiece 1. When the support rod 5 is open, the net 6 has storage space to hold the dental tissue. The net 6 opens and closes as the support rod 5 moves away from and closer to the mouthpiece 1.

[0036] It should be noted that during oral treatment, because tooth tissue is relatively light, after the mesh 6 holds the tooth tissue, the supporting force of the spring 15 can support the support rod 5. If the spring 15 deforms, the tooth tissue can still be held by the mesh 6, thus preventing the tooth tissue from being accidentally swallowed by the patient.

[0037] Furthermore, such as Figures 1 to 3 As shown, the mouthpiece 1 is provided with a first guide groove 10 and a second guide groove 11. The first guide groove 10 is straight and one end is connected to the channel cavity in the mouthpiece handle 2. The first guide groove 10 is used to place the keel 3, thereby restricting the movement direction of the keel 3. Four second guide grooves 11 are symmetrically arranged on both sides of the first guide groove 10. One end of the second guide groove 11 is connected to the first guide groove 10, and the other end is connected to the side wall of the mouthpiece 1. The tension rope 4 is placed in the second guide groove 11, and the movement direction of the tension rope 4 is restricted by the second guide groove 11.

[0038] Furthermore, the mouth lens 12 is mounted on the mouth lens 1. The lower surface of the mouth lens 12 is flat. The lower surface of the mouth lens 12 abuts against the upper surfaces of the first guide groove 10 and the second guide groove 11 to prevent the keel 3 and the tension rope 4 from deviating from the guide groove when moving.

[0039] Furthermore, such as Figure 1, Figure 6 , Figure 7 and Figure 8 As shown, a slider 7 is fixedly connected to the end of the keel 3 furthest from the mouthpiece 1. The slider 7 includes a pusher block 701 and a connecting block 702. The lower part of the pusher block 701 has an arc surface that matches the side curvature of the mouthpiece handle 2, allowing the pusher block 701 to slide along the length of the mouthpiece handle 2. The connecting block 702 consists of two perpendicular plates connected together. One end of the flat plate is fixedly connected to the end of the keel 3, and the flat plate is fixedly connected to the lower surface of the pusher block 701 through a vertical plate. A sliding hole 13 is provided on the mouthpiece handle 2, through which the vertical plate of the connecting block 702 passes. A cavity matching the shape of the connecting block 702 is provided inside the mouthpiece handle 2, allowing the slider 7 to move along the length of the mouthpiece handle 2, thereby moving the keel 3. When it is necessary to block tooth tissue during oral treatment, the net 6 can be opened and closed by moving the slider 7, making the operation simple and convenient.

[0040] Furthermore, such as Figure 6 , Figure 7 and Figure 8 As shown, a stop plate 8 is provided on the slider 7, and a connecting rod is fixedly connected to the slider 7. One end of the stop plate 8 is sleeved on the connecting rod, allowing the stop plate 8 to rotate around the connecting rod. A stop block 9 is provided on one side of the slider 7 on the mouth mirror handle 2. Under the action of elasticity, the support rod 5 moves away from the mouth mirror 1. At this time, the mouth mirror 1 drives the tension rope 4 and moves the keel 3 towards the mouth mirror 1. The stop plate 8 abuts against the stop block 9, preventing the slider 7 from moving further, thereby keeping the opening range of the net bag 6 fixed, which is convenient for oral treatment. Four stop blocks 9 are provided on the mouth mirror handle 2. The opening range of the net bag 6 is different in different positions. The opening degree of the net bag 6 can be adjusted by adjusting the moving distance of the slider 7 according to the size of the patient's mouth, which improves the applicability of this utility model.

[0041] Furthermore, such as Figure 2 , Figure 3 and Figure 9 As shown, the second guide groove 11 has a limiting step 16 at the end away from the first guide groove 10. One end of the spring 15 is fixedly connected to the support rod 5, and the other end is connected to the limiting step 16. The limiting step 16 provides a force point for the spring 15. At the same time, when the support rod 5 is in contact with the mouth lens 1, the spring 15 can be compressed and stored in the second guide groove 11, so that the support rod 5 can be completely in contact with the side wall of the mouth lens 1, reducing the volume of the mouth lens of this utility model and increasing the operating space during oral examination.

[0042] Furthermore, such as Figure 2 and Figure 3As shown, a groove 14 is provided on the side wall of the mouth mirror 1. The support rod 5 can be stored in the groove 14. When the net bag 6 does not need to be opened, storing the support rod 5 in the groove 14 can reduce the volume of the mouth mirror and increase the operating space during oral examination.

[0043] Furthermore, the support rod 5 is wrapped with a scratch-resistant layer, which prevents the support rod 5 from scratching the patient's mouth when the net bag 6 is open.

[0044] The working principle of this invention is as follows: When dental treatment does not require tooth tissue removal, the support rod 5 is in contact with the side wall of the mouthpiece 1, and the spring 15 is in a compressed state. The stop plate 8 and stop block 9 on the slider 7 abut against each other, preventing the slider 7 from moving. When tooth tissue needs to be removed, the stop plate 8 is rotated to disengage from the stop block 9. At this time, the spring 15 extends under the action of elastic force, causing the support rod 5 to move away from the mouthpiece 1. During the process of moving away, the support rod 5 drives the connected tension rope 4 to move, which in turn drives the keel 3 to move and the slider 7 to move. At the same time, the net 6 gradually opens as the support rod 5 moves away. When the net 6 opens to a suitable range, the stop plate 8 is rotated to abut against the stop block 9. At this time, the slider 7 stops moving, and the net 6 maintains a fixed opening range, allowing tooth tissue to be removed. After the oral treatment is completed, rotate the stop plate 8 to disengage from the stop block 9, and move the slider 7 away from the mouth lens 1. At this time, the keel 3 moves with the slider 7 and pulls the tension rope 4 to bring the support rod 5 close to the mouth lens 1. Slide the slider 7 until the support rod 5 is close to the mouth lens 1 and rotate the stop plate 8 to disengage from the stop block 9. The mouth lens returns to its initial use state.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
