The present invention solves the problem that the size of existing oral support instruments is relatively fixed and cannot be adjusted according to the patient's condition, which reduces the patient's comfort during treatment. In addition, the existing oral support instruments do not have a lighting function and require the use of special lighting tools to examine the oral cavity, which increases the cost of oral examination.

[0004] The above-mentioned prior art places an auxiliary support device in the oral cavity, which contacts the inner side of the lower gum and the upper jaw, so that the mouth is in an open state, thereby solving the problem of being able to automatically adjust the width of the device according to the size of the patient's mouth, better adapt to the patient's mouth, and improve the patient's comfort during treatment. However, during the support process of the auxiliary support device, the lower L-shaped plate located on the inner side of the lower gum will move downward due to the downward pressure, causing damage to the lower gum. At the same time, the auxiliary support device is located in the oral cavity. When the patient needs to remove wisdom teeth, the operation space for medical staff to remove the teeth is reduced. Therefore, an auxiliary support device for oral medical examination is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1 to 9 As shown, the present invention provides an auxiliary support device for oral medical examination, including a mouth expander 1, and further comprising:

[0039] The tooth support component 3 is fixed on the expander 1;

[0040] The tooth support assembly 3 includes a fixing frame 37 fixed to one end of the inner wall of the expander 1 through a connecting mechanism, and a guide plate 35 is fixed on the fixing frame 37, and a guide groove 36 is formed on the guide plate 35;

[0041] A sliding member 38 is slidably provided on the guide groove 36, and a support member 31 is fixedly mounted on the sliding member 38. A piston rod 32 is sleeved on both ends of the support member 31, and a reset elastic member 34 is sleeved on the outside of the piston rod 32. The end of the piston rod 32 is hingedly connected to a contact horizontal plate 33.

[0042] The contact horizontal plate 33 is made of silicone material, and the gap between the two contact horizontal plates 33 gradually decreases from the end close to the fixing frame 37;

[0043] The mouth expander 1 is used to support the lips of the oral cavity and is placed in the oral cavity through two contact transverse plates 33 and located on the inner cheek of one side, with the upper and lower teeth respectively located on the two contact transverse plates 33.

[0044] When a patient needs to have his wisdom teeth extracted, the patient's lips are supported by the mouth expander 1. The tooth-supporting assembly 3 is installed at one end of the inner wall of the mouth expander 1 through a connecting mechanism, and away from the end where the wisdom teeth need to be extracted. The contact cross plate 33 is pushed to be located between the upper and lower teeth. The upper and lower teeth of the patient are supported by the two contact cross plates 33, thereby achieving support for the patient's mouth. As the distance between the two contact cross plates 33 gradually decreases, it is more adapted to the shape of the teeth opening. In this process, the patient's upper and lower teeth are supported by the contact cross plates 33, and the teeth are engaged in the contact cross plates 33 to avoid gum damage during the support process, ensure the stability of the support, improve the patient's comfort, and stay away from the side where the wisdom teeth are extracted to avoid oral support occupying a large space, thereby increasing the operating space for medical staff.

[0045] On the contrary, when the wisdom tooth on the other side needs to be extracted, the tooth support assembly 3 is installed on the other end of the inner wall of the mouth expander 1 through the connecting mechanism, so that the oral cavity can be supported when any wisdom tooth is extracted.

[0046] like Figure 4-Figure 8 As shown, the middle portion of the support member 31 is connected to a gas injection pipe 311. A through groove 312 is formed on the outside of the gas injection pipe 311. A second valve ring 318 is fixedly installed inside the gas injection pipe 311. The second valve ring 318 has a second through hole 317. A valve ring 313 is sleeved inside the gas injection pipe 311. The valve ring 313 has a first through hole 314. A limit ring 310 is fixedly installed inside the gas injection pipe 311.

[0047] Initially, the piston rod 32 is located in the support member 31, the first through hole 314 and the second through hole 317 are in a non-overlapping state, the contact cross plate 33 is placed in the oral cavity, the first through hole 314 and the second through hole 317 overlap, and the contact cross plate 33 is reset under the action of the reset elastic member 34 and fits the upper and lower teeth.

[0048] Initially, the second through hole 317 coincides with the first through hole 314 and is connected. By pressing the piston rod 32 downward and positioning it in the support member 31, and stretching the reset elastic member 34, the valve ring 313 is rotated to disconnect the first through hole 314 and the second through hole 317, thereby reducing the distance between the two contact transverse plates 33 and making it easier to place the contact transverse plates 33 in the patient's mouth. After being placed in the appropriate position, the valve ring 313 is rotated to make the first through hole 314 coincide with the second through hole 317, and gas enters the support member 31. Under the action of the reset elastic member 34, the contact transverse plates 33 are gradually pushed out of the support member 31, increasing the distance between the two contact transverse plates 33, and supporting the upper and lower teeth through the two contact transverse plates 33. The valve ring 313 is then rotated to disconnect the first through hole 314 and the second through hole 317, and the support member 31 is in a sealed state, so that the patient's mouth can be supported by the two contact transverse plates 33.

[0049] like Figure 4-Figure 8 As shown, a guide rod 315 is fixed to the side of the valve ring 313, a fixing member 331 is fixed to the fixing frame 37, and a limit block 333 is provided on the fixing member 331;

[0050] A guide block 319 is fixedly mounted on the guide rod 315 , and a notch 316 is provided on the guide block 319 ;

[0051] The fixing member 331 is provided with an indicator mark 332 , and the indicator mark 332 is kept level with the second through hole 317 ;

[0052] The guide block 319 and the first through hole 314 remain vertical;

[0053] The notch 316 overlaps with the fixing member 331 , and when the guide rod 315 and the valve ring 313 are rotated and the guide block 319 and the indicator mark 332 overlap, the first through hole 314 overlaps with the second through hole 317 .

[0054] The guide rod 315 pushes the support member 31 to slide along the guide groove 36 through the sliding member 38, so that the contact cross plate 33 is located in the patient's oral cavity. Since the initial piston rod 32 is located in the support member 31 and the reset elastic member 34 is in the pulled state, and the support member 31 is in a sealed state, after being pushed to the appropriate position, the notch 316 coincides with the fixing member 331. At this time, the guide rod 315 is rotated to make the guide block 319 coincide with the indicator 332, the first through hole 314 and the second through hole 317 coincide, and gas can enter the support member 31. The reset elastic member 34 resets and pulls the contact cross plate 33, thereby increasing the distance between the two contact cross plates 33. The guide rod 315 is then rotated to make the guide block 319 contact the limit block 333, the first through hole 314 and the second through hole 317 are disconnected, and the support member 31 is in a sealed state, so that the patient's teeth can be supported. At the same time, the contact cross plate 33 is limited by the cooperation of the guide block 319 and the fixing member 331.

[0055] like Figure 5 、 Figure 7 and Figure 9 As shown, the opposite surfaces of the two contact transverse plates 33 are hinged with a first support rod 321 and a second support rod 322 , respectively, and the opposite ends of the first support rod 321 and the second support rod 322 are hinged.

[0056] An air guide tube 323 is fixedly mounted in the middle of the support member 31 . A transmission rod 324 is movably sleeved inside the air guide tube 323 . The support member 31 is in communication with the interior of the air guide tube 323 through a communication hole 326 .

[0057] The second support rod 322 is longer than the first support rod 321 . An abutment block 325 is fixed to the end of the transmission rod 324 . One corner of the abutment block 325 is arc-shaped and abuts against the second support rod 322 .

[0058] During the process of supporting the teeth through the contact cross plate 33, after the contact cross plate 33 is subjected to the pressure of the teeth, it moves into the support member 31 through the piston rod 32, compressing the internal gas, and since the air guide tube 323 is connected with the support member 31 through the connecting hole 326, the transmission rod 324 and the interference block 325 are pushed toward the outward end by the pressure in the support member 31, and the interference block 325 interferes with the second support rod 322, and a supporting force is applied to the second support rod 322 through the interference block 325, and the support area of ​​the contact cross plate 33 is increased through the second support rod 322 and the first support rod 321, thereby improving the stability of the contact cross plate 33.

[0059] like Figure 1 and Figure 2 As shown, an inner support plate 2 is fixedly mounted on the other end of the inner wall of the expander 1, and the inner support plate 2 is made of an acrylic plate.

[0060] The patient's lips are supported by the mouth expander 1, and the inner support plate 2 is located on the inner wall of the patient's oral cheek. The inner support plate 2 expands the inner wall of the patient's oral cheek, thereby increasing the operating space for medical staff to extract wisdom teeth.

[0061] like Figure 2 and Figure 4 As shown, a contact plate 41 is fixedly mounted on the guide plate 35 via a connecting piece 42 , and the top and bottom of the contact plate 41 are arc-shaped.

[0062] The contact transverse plate 33 supports the patient's teeth, and the contact plate 41 resists the patient's tongue, thereby preventing the tongue from being damaged during the wisdom tooth extraction process.

[0063] At the same time, the contact plate 41 and the inner support plate 2 are both made of acrylic plates. During the wisdom tooth extraction process, the surgical light is irradiated on the contact plate 41 and the inner support plate 2. According to the characteristics of the acrylic plate, the irradiated light is diffused into the cavity, avoiding the occurrence of blind spots in the light during the wisdom tooth extraction process and ensuring the smooth extraction of the wisdom tooth.

[0064] The working principle and use process of the present invention:

[0065] The patient's lips are supported by the expander 1, and the tooth-supporting assembly 3 is installed at one end of the inner wall of the expander 1 through a connecting mechanism, and is away from the end where the wisdom tooth needs to be extracted. The initial second through hole 317 coincides with the first through hole 314 and is connected. By pressing the piston rod 32 downward, it is located in the support member 31, and the reset elastic member 34 is stretched. The support member 31 is pushed through the guide rod 315 to slide along the guide groove 36 through the sliding member 38, so that the contact cross plate 33 is located in the patient's mouth. Since the initial piston rod 32 is located in the support member 31 and the reset elastic member 34 is in a pulled state, and the support member 31 is in a sealed state, after being pushed to the appropriate position, the notch is 316 coincides with the fixing member 331. At this time, the guide rod 315 is rotated to make the guide block 319 coincide with the indicator mark 332, and the first through hole 314 coincides with the second through hole 317. Gas can enter the support member 31, and the reset elastic member 34 resets and pulls the contact transverse plate 33, thereby expanding the distance between the two contact transverse plates 33. The guide rod 315 is then rotated to make the guide block 319 contact the limit block 333, and the first through hole 314 and the second through hole 317 are disconnected. The support member 31 is in a sealed state, and the patient's teeth can be supported. At the same time, the contact transverse plate 33 is limited by the cooperation of the guide block 319 and the fixing member 331.

[0066] During the process of supporting the teeth through the contact cross plate 33, after the contact cross plate 33 is subjected to the pressure of the teeth, it moves into the support member 31 through the piston rod 32, compressing the internal gas, and since the air guide tube 323 is connected with the support member 31 through the connecting hole 326, the transmission rod 324 and the interference block 325 are pushed toward the outward end by the pressure in the support member 31, and the interference block 325 interferes with the second support rod 322, and a supporting force is applied to the second support rod 322 through the interference block 325, and the support area of ​​the contact cross plate 33 is increased through the second support rod 322 and the first support rod 321, thereby improving the stability of the contact cross plate 33.
