Description

Technical Field

[0001] The invention relates to the field of oral medical equipment, in particular to an oral opening device suitable for clinical use in stomatology. Background Art

[0002] The oral opening device is a commonly used auxiliary tool in the clinical practice of dentistry. It is used to fix the patient's oral opening state so that doctors can complete various treatment operations. However, with the development of dentistry, treatment projects have become increasingly complex, such as dental implant surgery, orthognathic surgery, periodontal disease treatment, etc., which puts higher requirements on the opening device;

[0003] Traditional opening devices are mostly mechanical structures, which maintain the opening state through the tension of the clamp or a locking device. This type of device is relatively simple in design, low in manufacturing cost, and easy to operate. It is widely used in general examinations and simple treatments.

[0004] For existing opening devices, firstly, most of the current oral opening devices are rigid fixed structures, and their contact surface with the patient's oral cavity is usually made of hard materials. During long-term surgery, this design is easy to exert excessive pressure on the oral soft tissue. Since the facial muscle tension of the patient will change during the treatment, the rigid fixed device is difficult to adapt to these dynamic changes; secondly, in complex oral treatment, the tongue pressing and saliva suction functions usually need to be completed by two devices respectively. This multi-device collaborative design not only occupies the surgical space, but also increases the complexity of the doctor's operation; finally, the installation and disassembly of most traditional opening devices rely on manual adjustment, and even require the use of tools. Component fixation is usually achieved through screws, buckles or other mechanical connection methods. Although these methods are stable, the adjustment process is time-consuming and increases the time for equipment preparation. In addition, the materials of the components of the device are different. For example, the material of the contact component is rubber and the clamp body is metal. If the same disinfection method is selected, it will have a certain impact on the service life of the device. Summary of the invention

[0043] The connecting rope 704 can be used to mount the tongue depressor 705 to the splicing assembly, and the tongue depressor 705 can accommodate the patient's tongue and provide a point of action for subsequent saliva suction operations;

[0044] The splicing assembly includes a slider 702, a slide groove 701 is provided on the second contact plate 604, the slider 702 is arranged in the slide groove 701, an assembly column 703 is provided on the slider 702, and the assembly column 703 is connected to one end of the connecting rope 704 close to the second contact plate 604;

[0045] By sliding between the slider 702 and the slide groove 701, the tongue depressor 705 can be easily removed from the contact component 6; the assembly column 703 provides a position for the installation of the connecting rope 704, and is a component that connects the slider 702 and the connecting rope 704, thereby realizing the assembly operation.

[0046] Please refer to the attached Figure 1 , Attachment Figure 4 , Attachment Figure 7 The tongue depressing mechanism 7 is provided with a saliva suction mechanism 8, the saliva suction mechanism 8 includes a saliva suction port 801, the saliva suction port 801 is provided on the tongue depressing plate 705 in the tongue depressing mechanism 7, the saliva suction port 801 is connected to the end a of the sealing cover 803 through the saliva suction hose 802, the bottom of the sealing cover 803 is provided with a collecting tank 804, and the end b of the sealing cover 803 is provided with a power component;

[0047] The saliva suction port 801 can transport the saliva produced under the tongue from the oral cavity to the outside through the saliva suction hose 802. The sealing cover 803 is a component for the collection tank 804 to achieve sealing, and the collection tank 804 plays the role of collecting saliva.

[0048] The power assembly includes a negative pressure pump 806, which is disposed on the collection tank 804. The output end of the negative pressure pump 806 is connected to the b end of the sealing cover 803 through a negative pressure tube 805; the a end of the sealing cover 803 is the IN end, and the b end is the OUT end;

[0049] The negative pressure pump 806 provides power for the saliva suction operation, and the negative pressure tube 805 serves as a connection, so that negative pressure is generated inside the collection tank 804.

[0050] Working principle: The equipment is assembled before use. The medical staff rotates the knob 506 slightly to rotate the reel shaft 505. The rotating reel shaft 505 reels the traction rope 504. The other end of the reeled traction rope 504 pulls the latch 501 to put the latch 501 into the installation slot 502. During the movement of the latch 501, the installation spring 503 is compressed. The installation spring 503 stores elastic potential energy. After the installation column 601 of the first contact plate 602 is inserted into the first clamp body 1 and the second clamp body 2, the knob is released and the elastic potential energy of the installation spring 503 is used to reset the latch 501. When the latch 501 is reset, it is inserted into the pin hole 507 on the installation column 601, so that the contact assembly 6 can be fixed on the first clamp body 1 and the second clamp body 2.

[0051] Then, the slider 702 slides into the slide groove 701 on the second contact plate 604, and the tongue depressor 705 connected by the assembly column 703 and the connecting rope 704 is fixed to one of the second contact plates 604. Then, the collection tank 804 is used as a storage container for storing saliva, and the saliva suction hose 802 connected to the saliva suction port 801 of the tongue depressor 705 is connected to the IN end of the sealing cover 803;

[0052] When in use, the medical staff puts the first contact plate 602 and the second contact plate 604 in the contact assembly 6 into the patient's mouth, and the flexible contact layer 603 contacts the inside of the patient's mouth. By controlling the handles of the first pliers 1 and the second pliers 2, the handles of the first pliers 1 and the second pliers 2 are gradually brought closer together. During the process of bringing them closer together, the opening angle of the contact assembly 6 of the pliers head part gradually increases, so that the patient's mouth is opened, and the rack 401 on the second pliers 2 moves accordingly. When the rack 401 moves, the holding plate 402 supports the rack 401 to prevent the rack 401 from rotating, thereby achieving the effect of fixing the opening angle;

[0053] During the treatment, when the facial muscle tension of the patient changes, the first contact plate 602 and the second contact plate 604 rotate slightly through the fine-tuning shaft 605, so that the flexible contact layer 603 can adapt to the tension change. After the change is completed, the torsion spring 606 can reset the first contact plate 602 and the second contact plate 604, thereby ensuring the fixation effect. The patient's tongue is inserted into the tongue depressor 705. While the tongue is fixed, the saliva generated during the treatment process is generated by the negative pressure pump 806 through the negative pressure tube 805 to generate negative pressure inside the collection tank 804. The generated negative pressure causes the saliva to be collected into the collection tank 804 through the saliva suction port 801 and the saliva suction hose 802;

[0054] After the treatment is completed, the rack 401 is rotated by pressing the clamp plate 402, and the clamp head parts of the first clamp body 1 and the second clamp body 2 are close to each other. Then the reset plate 403 makes the clamp plate 402 rebound and fix the rack 401 again. The medical staff takes the device out of the patient's mouth and disassembles the components again by sliding the slider 702 and turning the knob 506 to facilitate subsequent disinfection in different ways, thereby extending the service life of the device.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
