[0079] The first support member 10 includes a holding portion 101, a spreading portion 102, and a lifting portion 103. A slot 1011 is provided on the rear side surface of the holding portion 101, and the slot 1011 extends along the length direction of the holding portion 101. The spreading portion 102 is in a "C" shape, and the "C" shape structure can provide a corresponding operation space after spreading the patient's oral cavity, facilitating the entry and exit of treatment instruments. One end of the spreading portion 102 is connected to the upper end of the outer front side surface of the holding portion 101, and the lifting portion 103 is provided at the other end of the spreading portion 102 for lifting the upper part of the patient's teeth.
[0080] The second support member 20 includes a plug-in portion 201 and a tongue pressing portion 202. The plug-in portion 201 is slidably inserted into the slot 1011, and one end of the tongue pressing portion 202 is connected to the upper end of the plug-in portion 201, and the other side extends toward the rear side of the plug-in portion 201.
[0081] The first protective member 104 is detachably provided on the lifting portion 103 for abutting against the upper teeth of the patient.
[0082] The second protective member 203 is detachably provided on the tongue pressing portion 202 for abutting against the lower teeth of the patient.
[0083] The locking mechanism 204 is provided on the holding portion 101 for locking and fixing the position of the plug-in portion 201.
[0084] Based on the above, by introducing the first protective member 104 and the second protective member 203, which are respectively detachably provided on the lifting portion 103 and the tongue pressing portion 202, these protective members can directly abut against the upper and lower teeth of the patient, effectively avoiding scratches or injuries that may be caused by direct contact between the metal material and the teeth, greatly improving the safety during the treatment process, reducing the pain of the patient and the risk of subsequent complications. The design of the first support member 10 and the second support member 20 allows for adjustment of the length of the mouth opener; the plug-in portion 201 is slidably inserted into the slot 1011, and together with the fixing of the position of the plug-in portion 201 by the locking mechanism 204, medical staff can flexibly adjust the opening degree of the mouth opener according to the actual situation of the patient, ensuring that the operation is neither excessive nor insufficient, and improving the accuracy and comfort of the treatment.
[0085] Preferably, in an embodiment of the present invention, the lifting portion 103 includes a collar 1031 and a supporting piece 1032.
[0086] The collar 1031 is sleeved on the spreading portion 102.
[0087] The middle part of the supporting piece 1032 is bent downward to form an arc, and one end of the supporting piece 1032 is connected to the side surface of the collar 1031.
[0088] It can be understood that the design of the collar 1031 sleeved on the spreading portion 102 enables the lifting portion 103 to be stably connected to the end of the spreading portion 102. This stable connection method helps to ensure that the patient's oral cavity remains in a stable open state during the use of the mouth opener, thereby improving the stability of the treatment and the comfort of the patient. At the same time, the arc design formed by the middle part of the supporting piece 1032 being bent downward can better fit the shape of the upper teeth of the patient, reducing the pressure on the teeth, further improving the comfort, and also preventing the teeth from slipping off the lifting portion 103.
[0089] Preferably, in an embodiment of the present invention, the first protective member 104 includes a first flexible pad 1041 and a binding strap 1043 .
[0090] The first flexible pad 1041 is adapted to the upper surface contour of the supporting sheet 1032 . The first flexible pad 1041 has a first air cavity 1042 formed therein, and the first air cavity 1042 contains gas.
[0091] The binding strap 1043 is disposed on the bottom surface of the first flexible pad 1041 to fix the first flexible pad 1041 on the supporting sheet 1032 .
[0092] Thus, the design of the first flexible pad 1041 matching the upper surface contour of the supporting sheet 1032 ensures that the first flexible pad 1041 can fit tightly on the supporting sheet 1032, providing a soft and comfortable contact surface for the upper teeth of the patient. The design of the first air cavity 1042 inside the first flexible pad 1041 allows the flexible pad to have better cushioning performance by containing gas, which can further reduce the impact and pressure on the patient's teeth, thereby enhancing protection and comfort.
[0093] The design of the strap 1043 enables the first flexible pad 1041 to be firmly fixed on the supporting sheet 1032, thus preventing discomfort or injury to the patient due to movement or falling off during use. This firm fixing method also improves the overall stability and reliability of the mouth opener.
[0094] Advantageously, in another embodiment of the present invention, two supporting portions 103 are provided, one of the two supporting portions 103 is fixed to the other end of the propping portion 102 , and the other of the two supporting portions 103 is movably provided at the other end of the propping portion 102 .
[0095] Thus, by providing a movable support portion 103, the mouth opener can more flexibly adapt to the oral structures and tooth arrangements of different patients. Medical staff can adjust the position of the movable support portion 103 according to the specific conditions of the patient to ensure that the mouth opener can stably and comfortably open the patient's mouth, which is convenient for subsequent treatment operations. This design improves the adaptability and flexibility of the mouth opener, allowing it to play a role in a wider range of treatment scenarios.
[0096] At the same time, the design of the two supporting parts 103 enables the mouth opener to disperse the force more evenly when opening the mouth, reducing the local pressure on the patient's teeth and oral tissues. This optimization helps to improve the patient's comfort during treatment, reduce pain and discomfort, and thus help the patient cooperate with the treatment better.
[0097] It should be noted that in order to ensure that the movable supporting portion 103 maintains the corresponding horizontal extension direction, a guide portion may be further provided between the ring 1031 and the support portion 102. For example, a convex ridge is provided on the inner wall of the ring 1031, and a guide groove is transversely provided on the surface of the support portion. The convex ridge and the guide groove are slidably matched, thereby ensuring the lateral sliding of the supporting portion 103 and maintaining it in the corresponding horizontal position (i.e., it will not pivot along the support portion 102).
[0098] Preferably, in an embodiment of the present invention, the second protective member 203 includes a bottom sheet 2031 and a second flexible pad 2032 .
[0099] Both ends of the upper surface of the bottom film 2031 are provided with a clamping portion 20311, and the two clamping portions 20311 can be clamped on both sides of the tongue-pressing portion 202 to fit and fix the bottom film 2031 on the bottom surface of the tongue-pressing portion 202; the two clamping portions 20311 are both made of deformable materials, and the upper ends of the two clamping portions 20311 are provided with a protruding structure on the opposite side, which can be deformed by pressure during installation, so that it can be clamped on the tongue-pressing portion 202. After installation, the two protruding structures will be on the upper surface of the tongue-pressing portion 202, so that the bottom film 2031 is fixed on the tongue-pressing portion 202.
[0100] The second flexible pad 2032 is disposed on the bottom surface of the bottom film 2031 , and the middle portion of the second flexible bottom surface is concave upward to form an arc-shaped surface.
[0101] In this way, the design of the clamping portion 20311 on the upper surface of the bottom film 2031 enables the second protective member 203 to be firmly fixed on the bottom surface of the tongue depressing portion 202. Through the clamping mechanism, the bottom film 2031 can fit tightly on the tongue depressing portion 202, avoiding discomfort or injury to the patient due to movement or falling off during use. This stable fixing method improves the stability and reliability of the mouth opener during use. The setting of the second flexible pad 2032 provides a soft and comfortable contact surface for the patient's lower teeth. The arc surface design formed by the upward depression in the middle of the bottom surface of the second flexible pad 2032 can better fit the shape of the patient's lower teeth, reduce the pressure on the teeth, and further enhance the protection and comfort. This design helps to reduce the pain and discomfort of the patient during the treatment process and improve the treatment experience.
[0102] Preferably, in an embodiment of the present invention, a second air cavity 20321 is formed inside the first flexible pad 1041 , and the second air cavity 20321 contains gas.
[0103] Thus, the design of the second air cavity 20321 enables the first flexible pad 1041 to more effectively disperse and absorb the impact force when under pressure, reducing the direct compression on the patient's teeth and oral tissues. This buffering performance helps improve the comfort of the patient during the treatment, reducing pain and discomfort, and thus contributing to the patient's better cooperation with the treatment.
[0104] Preferably, in an embodiment of the present utility model, a through groove 2021 is provided in the middle of the tongue pressing part 202, and the through groove 2021 extends along the length direction of the tongue pressing part 202 for the insertion of a drainage tube.
[0105] Thus, the design of the through groove 2021 provides a direct channel for the insertion of the drainage tube, enabling medical staff to more conveniently insert the drainage tube during oral treatment. This not only simplifies the operation process but also improves the treatment efficiency.
[0106] Preferably, in an embodiment of the present utility model, an arc part 2022 is provided at the front end of the upper surface of the tongue pressing part 202, and the arc part 2022 covers above the through groove 2021 for pressing down the drainage tube.
[0107] Thus, the setting of the arc part 2022 provides a stable support surface. When the drainage tube is inserted into the through groove 2021, the arc part 2022 can naturally fit above the drainage tube to press down and fix the drainage tube. This stable fixing method prevents the drainage tube from shifting or falling off during the treatment, ensuring the continuity and effectiveness of drainage. The design of the arc part 2022 on the upper surface of the tongue pressing part 202 enables the mouth opener to not only have the function of opening the oral cavity but also have the ability to stably fix the drainage tube. This multi-functional design enhances the practicality of the mouth opener, enabling it to play a role in a wider range of treatment scenarios.
[0108] Preferably, in an embodiment of the present utility model, the locking mechanism 204 includes a pressing piece 2041 and a limiting part 2044.
[0109] Two supporting parts 1012 are provided on the surface of the holding part 101, and the two supporting parts 1012 are spaced apart. Both sides of the pressing piece 2041 are provided with rotating shafts 2042. The pressing piece 2041 is arranged between the two supporting parts 1012, and the two rotating shafts 2042 are respectively rotatably connected to the supporting parts 1012. Torsion springs 2043 are installed on both of the two rotating shafts 2042;
[0110] The limiting part 2044 is arranged at the end of the pressing piece 2041 and passes through the holding part 101 and extends into the slot 1011;
[0111] Among them, a plurality of card slots 2011 are provided on the surface of the insertion part 201. The plurality of card slots 2011 extend along the length direction of the insertion part 201, and one end of the limiting part 2044 is inserted into one of the card slots 2011.
[0112] In this way, through the connection of the rotating shaft 2042 between the pressing piece 2041 and the supporting part 1012 and the action of the torsion spring 2043, when the pressing piece 2041 is pressed, the limiting part 2044 can automatically pop out of the card slot 2011 to unlock the insertion part 201, facilitating the adjustment of the degree of opening the patient's oral cavity. When the pressing piece 2041 is released, due to the action of the torsion spring 2043, the pressing piece 2041 can be reset, and the limiting part 2044 is recaptured in the corresponding card slot 2011 to achieve self-locking. This design ensures the stability and safety of the mouth opener when opening the oral cavity, avoiding discomfort or harm to the patient caused by loosening or falling off. A plurality of card slots 2011 are provided on the surface of the insertion part 201 and extend along its length direction, enabling the limiting part 2044 to be inserted into different card slots 2011 to adapt to different locking positions. This adjustability enables the mouth opener to better adapt to the oral structures and treatment requirements of different patients, improving the applicability and flexibility of the mouth opener.
