Description

Technical Field

[0001] The invention relates to the technical field of oral medicine, and in particular to an oral opening device for oral medicine with a size-adjustable function. Background Art

[0002] Dentistry is an important branch of medicine that focuses on the study, diagnosis, treatment and prevention of various diseases and conditions in the oral and maxillofacial regions. In clinical practice, in order to ensure a comprehensive and accurate examination or necessary treatment, patients are usually required to keep their mouths open. However, in some cases, especially when the examination process is long, the patient may unconsciously close his mouth due to fatigue, or cannot achieve the ideal opening degree due to physiological limitations. In order to solve these problems, a series of mouth opening devices are used clinically to assist doctors in completing their work.

[0003] At present, there are roughly three types of oral retractors on the market, which can be simply summarized as pliers, fixed and retractors. Among them, pliers-type oral retractors are usually designed with a part for the patient to bite, and the jaws are separated by operating the pliers handle using the lever principle to achieve oral retraction. However, this device is mainly suitable for recovery after oral surgery, and its structural characteristics make it unsuitable for examination or treatment inside the oral cavity, because parts such as the pliers handle may hinder the examination or treatment.

[0004] Secondly, fixed oral opening devices are usually a transparent or translucent ring-shaped structure placed between the patient's lips and gums to open the mouth. Inspection or treatment instruments are operated through the inner diameter of the ring-shaped structure. However, such devices have adaptability issues because they are usually of fixed size and cannot be adjusted. The mouths of different patients vary in size, which makes it difficult for fixed devices to meet the needs of all patients. For patients with smaller mouths, the use of such devices may cause discomfort or injury; while for patients with larger mouths, sufficient mouth opening may not be achieved. Therefore, it is often necessary to prepare multiple devices of different sizes for use, which not only increases costs but also reduces efficiency.

[0005] Finally, the oral retraction device of the retraction type is designed with an adjustable size. It can be placed on the patient's gums or teeth and adjusted by adjusting tools. Although this device can be adjusted according to the size of the mouth of different patients, its use process is relatively complicated. When adjusting, the tool needs to be inserted into the mouth, and auxiliary tools may be required to observe the adjustment, which brings inconvenience to the operation. In addition, because the connecting parts such as hinges and brackets are located inside the mouth, they may partially or completely block certain areas of the mouth, affecting the comprehensiveness of the examination.

[0006] In view of this, although the existing technology has provided a variety of solutions to meet the needs of oral expansion, there is still room for improvement in improving user experience, simplifying operating procedures and enhancing functionality. Therefore, we need to make improvements to the above-mentioned defects.

[0007] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0018] The driving structure includes a turbine, which is rotatably connected to the inside of the outer shell two. A knob opening is opened on the circular surface of the outer shell two, and an adjusting knob is arranged in the knob opening. The adjusting knob is fixedly connected to the turbine and is provided with a cross-shaped slot. The adjusting knob can be driven to rotate by turning it with a screwdriver, thereby driving the turbine to rotate. A vortex rod is rotatably connected to the inside of the outer shell one, and the vortex rod is meshed with the turbine through the connection between the outer shell one and the outer shell two. A screw rod one is fixedly connected to the top of the vortex rod, and the screw rod one is threadedly connected to a threaded barrel one.

[0019] A further preferred scheme of the present invention is: the adjustment component includes a screw rod 2, a spiral block 1 is fixedly connected to the middle part of the screw rod 2, the top and bottom ends of the screw rod 2 are threadedly connected to a threaded barrel 2, the threads of the screw rod 2 at the upper and lower ends are distributed in opposite directions with the spiral block 1 as the midpoint, the ends of the threaded barrel 2 away from the screw rod 2 are fixedly connected to the rotating part, and the distance between the lip masks at the upper and lower ends can be changed by pinching the spiral block 1 and rotating the screw rod 2 so that the threaded barrel 2 moves in opposite or similar directions.

[0020] A further preferred scheme of the present invention is: the adjustment component includes a screw rod three, the middle part of the screw rod three is fixedly connected with a spiral block two, the top and bottom of the screw rod three are threadedly connected with a threaded barrel three, the separated ends of the threaded barrel three at the upper and lower ends are bearing-connected with a limiting part three, and the limiting part three is fixedly connected to the rotating part, and the position between the screw rod three and the threaded barrel three can be changed by holding the spiral block two and rotating any one of the threaded barrels three, thereby changing the distance between the lip covers at the upper and lower ends.

[0021] The top and bottom ends of the screw rod three are fixedly connected to the limiting part four, and the tube mouth of the threaded barrel three is buckled inwardly, and the buckled part and the limiting part four cooperate with each other to prevent the threaded barrel three from slipping off the screw rod three.

[0022] A further preferred solution of the present invention is that a plurality of tooth grooves are formed in the upper gum part and the lower gum part near the teeth, and the tooth grooves correspond to the distribution of human teeth and fit closely.

[0023] Compared with the prior art, the present invention has the following advantages including but not limited to:

[0024] 1. The present invention provides doctors with a variety of choices by designing different adjustment components, and the most suitable method can be selected to adjust the size according to specific circumstances and personal preferences.

[0025] 2. The present invention places the adjustment component outside the patient's mouth, which means that the doctor does not need to insert the tool into the patient's mouth when adjusting the mouth opening. In this way, on the one hand, it is not easy to cause damage to the patient's mouth due to misoperation; on the other hand, the external adjustment component does not require the doctor to use auxiliary tools to check the adjustment status, which improves the efficiency of adjustment.

[0026] 3. Another advantage of the external adjustment component is that the various supporting parts are arranged outside the oral cavity, which means that these parts will not block or partially block the oral cavity. When the patient opens his mouth, the doctor can have a clear view of the internal environment of the oral cavity, and can quickly conduct examinations or treatments without hindrance.

DETAILED DESCRIPTION

[0038] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] First embodiment:

[0040] Please refer to the instruction manual Figures 1 to 3, this embodiment discloses a mouth opening device for oral medicine with adjustable size. In this embodiment, the mouth opening device described in this application includes an upper gum portion 1 and a lower gum portion 2, a lip mask 4, a buckle structure and an adjustment component. Among them, the upper gum portion 1 and the lower gum portion 2 are arc-shaped, conforming to the direction of the gums in the human mouth and distributed up and down. The upper gum portion 1 and the lower gum portion 2 are both made of flexible skin-friendly materials, which enables them to have a certain deformation ability, and when they are inserted into the gums, they can minimize the patient's foreign body sensation. The two ends of the side facing the oral cavity are connected by a hinge 3 and rotate relative to the hinge 3. At the same time, the upper gum portion 1 and the lower gum portion 2 are provided with a plurality of tooth grooves 34 near the teeth. The tooth grooves 34 correspond to the distribution of human teeth and fit well.

[0041] Next, the above-mentioned lip mask 4 is arranged on the side of the upper gum part 1 and the lower gum part 2 away from the oral cavity. The lip mask 4 is made of a transparent material, is hollow inside, and has an opening. The openings of the upper and lower lip masks 4 are opened in opposite directions, and the patient's lips are wrapped through the opening, and can receive the patient's saliva to a certain extent, so that it will not affect the oral examination; and the buckle structure is arranged on both sides of the upper gum part 1 and the lower gum part 2, which is located at the edge of the mouth corner. Being arranged there, it can ensure that the buckle structure is sufficiently close to the hinge 3, and maximize the satisfaction that the structure will not affect the examination inside the oral cavity when the patient opens his mouth. More specifically, the above-mentioned snap-fit ​​structure includes a fixed block 5 fixed on the upper gum part 1 and the lower gum part 2, a small hole 6 is opened in the fixed block 5, a snap ring 7 is passed through the small hole 6, and the adjacent surfaces of the upper and lower snap rings 7 are fixedly connected with an extension part 8, an insertion shaft 9 is inserted on the extension part 8, and a rotating part 10 is rotatably connected to the insertion shaft 9. The rotating parts 10 at the upper and lower ends are used in conjunction with each other to connect the adjustment components.

[0042] In a preferred embodiment of the present invention, the above-mentioned adjustment component includes an adjustment rod 11, which is configured as a plurality of strip-shaped hard cylinders of different sizes and lengths, both ends of which are fixedly connected to the rotating part 10, and the rotating part 10 is made of a deformable material. The top and bottom ends of each of the above-mentioned different adjustment rods 11 are connected to the rotating part 10. Therefore, when the adjustment rod 11 needs to be replaced, the doctor only needs to open the connection between the rotating part 10 and the plug-in shaft 9 to deform the rotating part 10, thereby removing the adjustment rod 11 and selecting another adjustment rod 11 suitable for the current patient's oral opening degree for replacement according to actual needs.

[0043] Second embodiment:

[0044] In the first embodiment, the adjustment of the patient's mouth opening still requires frequent disassembly and assembly of the adjustment rod 11 to meet the needs, which is also inconvenient. Therefore, in order to be able to adjust the mouth opening without disassembly and assembly, the present invention provides another preferred embodiment.

[0045] Please refer to the instruction manual Figure 4 In another preferred embodiment of the present invention, while the main components (upper gum portion 1 and lower gum portion 2, lip mask 4, buckle structure) etc. remain unchanged, this embodiment replaces the adjustment component of the first embodiment with an upper toothed stick 12 and a lower toothed stick 13 that can move up and down relative to each other by replacing the adjustment stick 11. Specifically, the upper end of the upper toothed stick 12 and the lower end of the lower toothed stick 13 are fixedly connected to the rotating portion 10, and the other ends thereof are fixedly connected to a limiting portion 14. One end of the upper toothed stick 12 and the lower toothed stick 13 stick body close to the limiting portion 14 is fixedly connected with a sliding buckle portion 15, and the other ends of the sliding buckle portion 15 are sleeved on each other's stick bodies, so that the upper toothed stick 12 and the lower toothed stick 13 can slide in the sliding buckle portion 15, and the outer sides of the upper toothed stick 12 and the lower toothed stick 13 stick bodies are sleeved with a spring 16, and both ends of the spring 16 are fixedly connected to the sliding buckle portion 15.

[0046] When in use, the patient places his lips in the lip mask 4, the gums abut against the upper gum part 1 and the lower gum part 2, the teeth are placed in the tooth grooves 34, and the teeth apply force. Then, the upper gum part 1 and the lower gum part 2 will move closer to each other around the hinge 3, thereby driving the upper tooth stick 12 and the lower tooth stick 13 to move from far to near, that is, the two sliding buckle parts 15 thereon move away from each other. As the distance between the sliding buckle parts 15 increases, the spring 16 connected thereto will be stretched. The spring 16 generates a reverse deformation force during the stretching process. This deformation force will form a balance with the force applied to the device by the patient, thereby adjusting the mouth opening degree. Conversely, when the upper tooth stick 12 and the lower tooth stick 13 move from near to far, the effect produced is also the same. Through the adjustment component designed in this embodiment, the mouth opening degree can be quickly adjusted without frequent disassembly and assembly.

[0047] Third embodiment:

[0048] In the third embodiment described above, although there is no need to frequently disassemble and assemble the adjusting rod 11 to meet the adjustment needs, a disadvantage is that the adjustment range of the mouth-opening device made using this embodiment is limited by the bite pressure applied by the patient to the device. However, this bite pressure is unstable. When the patient bites for too long, fatigue will inevitably occur, and the adjustment will become unstable at this time. Therefore, in order to enable stable adjustment, the present invention provides another preferred embodiment.

[0049] Please refer to the instruction manual Figures 5-6In another preferred embodiment of the present invention, while the main components (upper gum portion 1 and lower gum portion 2, lip mask 4, buckle structure, etc.) remain unchanged, this embodiment replaces the upper tooth stick 12 and lower tooth stick 13 that can move up and down in the adjustment component of the second embodiment with a shell 17 and a threaded barrel 18 that can be displaced. Specifically, the shell 17 is hollow inside and has an open top. Its bottom end is fixedly connected to the rotating part 10. The top of the shell 17 has a place where a threaded barrel 18 is inserted. The top of the threaded barrel 18 is fixedly connected to a limiting part 19, and the limiting part 19 is fixedly connected to the rotating part 10. Therefore, the patient's mouth opening degree can be adjusted by only changing the relative position between the shell 17 and the threaded barrel 18. At the same time, a shell 20 is provided on one side of the above-mentioned shell 17, and the shell 17 and the shell 2 20 are connected to each other to form a accommodating chamber, and a driving structure is provided in the accommodating chamber for driving the threaded cylinder 18 to move relative to the shell 17, thereby changing the distance from the limiting part 2 19 to the bottom of the shell 17, and then adjusting the distance between the upper and lower lip covers 4.

[0050] More specifically, the driving structure includes a turbine 21, which is rotatably connected to the inside of the outer shell 20. A knob opening 22 is provided on the circular surface of the outer shell 20, and an adjusting knob 23 is provided in the knob opening 22. The adjusting knob 23 is fixedly connected to the turbine 21, and a cross-shaped slot is provided on it. An additional cross-shaped screwdriver is provided, and the adjusting knob 23 can be driven to rotate by screwing the screwdriver, thereby driving the turbine 21 to rotate. A vortex rod 24 is rotatably connected to the inner shell 17, and the vortex rod 24 is meshed with the turbine 21 through the connection between the outer shell 17 and the outer shell 20. A screw rod 25 is fixedly connected to the top of the vortex rod 24, and the screw rod 25 is threadedly connected to the threaded barrel 18.

[0051] Therefore, when using, the doctor can insert the cross-shaped screwdriver into the cross-shaped notch of the adjustment knob 23, and turn the screwdriver to drive the turbine 21 to rotate. Under the influence of the meshing, the worm rod 24 rotates accordingly, driving the screw rod 25 to rotate. Since the screw rod 25 is threadedly connected to the threaded barrel 18, under the influence of the threaded connection, the threaded barrel 18 will change its relative position with the screw rod 25, thereby changing its relative position with the housing 17, and adjusting the distance between the upper and lower lip masks 4. Through the above-mentioned adjustment method, the patient does not need to actively apply and maintain pressure, which relieves the fatigue of the patient's facial muscles and makes the mouth support more stable.

[0052] Fourth embodiment:

[0053] In the third embodiment described above, although the purpose of more stable adjustment of the opening is achieved, its defect is that it needs to be used with an additional cross-shaped screwdriver. Obviously, the screwdriver cannot be stored synchronously with the oral opening device of the present invention, and requires additional space for storage, which causes the cross-shaped screwdriver to be easily lost. When it is lost, if there is no other alternative tool, the opening degree of the oral opening device cannot be adjusted, which is inconvenient to use. In view of this, in order to achieve adjustment without the help of additional tools, the present invention provides another preferred embodiment.

[0054] Please refer to the instruction manual Figure 7 In another preferred embodiment of the present invention, while the main components (upper gum portion 1 and lower gum portion 2, lip mask 4, buckle structure, etc.) remain unchanged, the present embodiment replaces the adjustment assembly of the third embodiment by a displacement-variable housing 17 and a threaded barrel 18 with a screw rod 26 and two threaded barrels 28. Specifically, a screw block 27 is fixedly connected to the middle of the screw rod 26, and the top and bottom ends of the screw rod 26 are both threadedly connected to the threaded barrel 28. The threads of the upper and lower screw rods 26 are distributed in opposite directions with the screw block 27 as the midpoint, which means that Then, when the user holds the spiral block 1 27 and turns the screw rod 26, the threaded barrel 28 will have a tendency to rotate, and since the end of the threaded barrel 28 away from the screw rod 26 is fixedly connected to the rotating part 10, this tendency is limited, so the threaded barrel 28 is fixed, and only the screw rod 26 rotates. Therefore, under the influence of the threaded connection, displacement will occur between the screw rod 26 and the threaded barrel 28. Since the threads are up and down, the threaded barrels 28 at the upper and lower ends will move away or close synchronously, thereby changing the distance between the upper and lower lip masks 4. With such a design, when in use, the spiral block 1 27 can be manually turned without the need for additional tools to make adjustments.

[0055] Fifth embodiment:

[0056] In the fourth embodiment described above, although the purpose of adjustment without tools is achieved, the threaded barrels 28 at the upper and lower ends thereof are synchronously moved away from or close to each other, that is, the individual threaded barrels 28 cannot be rotated independently. In actual use, some patients have different degrees of opening of their upper and lower teeth, and the upper and lower openings cannot be adjusted independently, which will cause a problem of poor adaptation. Therefore, in order to solve this problem, the present invention provides another preferred embodiment.

[0057] Please refer to the instruction manual Figures 8 to 10In another preferred embodiment of the present invention, while the main components (upper gum portion 1 and lower gum portion 2, lip mask 4, buckle structure, etc.) remain unchanged, this embodiment replaces the adjustment component of the fourth embodiment with a screw rod 26 and two threaded barrels 28, with a screw rod 3 29 with two threaded barrels 31 threadedly connected thereto, and a spiral block 2 30 is also fixedly connected to the middle part of the screw rod 3 29. However, unlike the fourth embodiment, in this embodiment, the upper and lower threads of the screw rod 3 29 are consistent, not opposite, and the lower thread The separated ends of the cylinder 31 are both bearing-connected with the limiting part 32, and the limiting part 32 is fixedly connected to the rotating part 10, which results in that the threaded cylinder 31 can rotate relative to the rotating part 10, and at this time, the body of the screw rod 329 is in a state of being kept motionless during use. The doctor can screw any upper and lower threaded cylinder 31 separately according to actual use needs, so that it can change the distance between itself and the screw rod 329 separately to achieve adjustment. With such a design, there is no need to adjust the mouth opening of the patient's upper and lower teeth at the same time, which is more suitable for the actual situation of the patient. The top and bottom ends of the screw rod 329 are both fixedly connected with the limiting part 433, and the cylinder mouth of the threaded cylinder 31 is buckled inwardly, and its buckled part and the limiting part 433 cooperate with each other to prevent the threaded cylinder 31 from slipping on the screw rod 329.

[0058] Finally, in combination with the above five embodiments, since the upper gum portion 1 and the lower gum portion 2 are both made of flexible skin-friendly material, this enables them to have a certain deformation ability, and while better fitting the patient's mouth, it also allows a certain gap in the mouth opening on both sides adjusted by the adjustment component, that is, the mouth opening on both sides can be inconsistent within the range allowed by material deformation, so as to better adapt to the patient's mouth.

[0059] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
