Description

Technical Field

[0001] The invention relates to the technical field of oral cavity expansion and stenting, in particular to an oral cavity expansion and stenting device for oral cavity inspection. Background Art

[0002] When inspecting the teeth in the oral cavity, it is necessary to open the lips that cover the teeth to expose the teeth, and then the teeth can be inspected. Currently, the lips are generally stretched using a mouth stretcher. When using it, put the mouth stretcher in the mouth to stretch the lips that cover the teeth.

[0003] This type of mouth stretcher generally uses the toughness of the mouth stretcher's own material to expand the oral cavity. Using this method, the force used to stretch the mouth is entirely controlled by the strength of the toughness of the material used when manufacturing the mouth stretcher. After the mouth stretcher is manufactured, the force used to stretch the mouth is fixed, so that it cannot be adjusted later. In actual use, each person can withstand a different force to stretch the mouth. If the force to stretch the mouth is too great, the user will feel uncomfortable. If the force to stretch the mouth is too small, the user's mouth may not be stretched open. If the force to stretch the mouth cannot be adjusted, the force to stretch the mouth cannot be adjusted to the most comfortable level for the user according to the individual.

[0030] Example

[0031] See also Figure 1-Figure 9 A mouth expansion device for oral examination includes a mouth support device body 1 and a shell 2. The inner wall of the shell 2 is rotatably connected to two winding shafts 3, and a drawstring 4 is fixedly connected to a side wall of one side of the winding shaft 3. One end of the drawstring 4 passes through the shell 2 and extends to the outside of the shell 2. An elastic band 5 is fixedly connected to one end of the drawstring 4 located outside the shell 2, and a slider 6 is fixedly connected to one end of the elastic band 5. A button 7 is fixedly connected to a side wall of one side of the slider 6. A transparent sleeve 8 is provided on the outside of the elastic band 5, and one end of the transparent sleeve 8 is fixedly connected to the drawstring 4. A scale line 9 is marked on the outer wall of the transparent sleeve 8. Connecting straps 10 are fixedly connected to both ends of the mouth support device body 1, and a connecting hole 11 is opened on a side wall of one side of the connecting strap 10. A control component is arranged in the shell 2.

[0032] It can be seen from the above structure that: by setting a control component, the two winding shafts 3 can be controlled to wind the drawstring 4, etc., so that the drawstring 4, etc. pulls the mouth opener body 1, so that the mouth opener body 1 opens the patient's lips. In this way, by pulling and opening the patient's lips, it can be adjusted for different patients. By adjusting the force of pulling and opening the patient's lips, it can be ensured that the device can adjust the force of opening the patient's lips to the force that can just open the patient's lips for different patients, thereby ensuring the patient's comfort to the greatest extent.

[0033] Furthermore, the control component includes a rotating shaft 12 rotatably connected to the inner wall of the shell 2, and the outer wall of the rotating shaft 12 is fixedly sleeved with a first gear 13, the outer walls of the two winding shafts 3 are fixedly sleeved with a second gear 14, and the second gear 14 is meshed with the first gear 13, the outer wall of the rotating shaft 12 is fixedly sleeved with a ratchet 15, and one side of the ratchet 15 is provided with an oblique stopper 16, the outer wall of the oblique stopper 16 is sleeved with a spring 17, one end of the spring 17 is fixedly connected to the oblique stopper 16, and the other end of the spring 17 is fixedly connected to the shell 2, and one end of the oblique stopper 16 passes through the shell 2 and extends to the outside of the shell 2; by setting the rotating shaft 12, the first gear 13 and the second gear 14 for use in combination, the rotating shaft 12 can be rotated to control the rotation of the two winding shafts 3. When in use, the rotating rotating shaft 12 drives the first gear 13 to rotate, and the rotating second gear 14 drives the first gear 13 to rotate. A gear 13 drives the second gear 14 to rotate, and the rotating second gear 14 rotates the winding shaft 3, so that the winding shaft 3 is wound around the drawstring 4, and the wound drawstring 4 pulls the elastic belt 5 and the pull head 6, so that the pull head 6 pulls the connecting belt 10 and the mouth support device body 1, so that the mouth support device body 1 opens the patient's lips. By opening the patient's lips in this way, the force of opening the patient's lips can be controlled, and the force of the device pulling the patient's lips can be controlled, so that for different patients, the device can be adjusted to a force suitable for opening the patient's lips; by setting the ratchet 15 and the oblique stopper 16, etc. for use, when in use, if the adjusted device opens the patient's lips with too much force, it only needs to pull the oblique stopper 16, and then the mouth support device body 1 can quickly release the involvement of the patient's lips, so as to reduce the damage caused by the excessive force of opening the patient's lips.

[0034] Furthermore, a spring spring 18 is sleeved on the outer wall of one of the winding shafts 3, and one end of the spring spring 18 is fixedly connected to the winding shaft 3, and the other end of the spring spring 18 is fixedly connected to the adjusting shaft 19, and one end of the adjusting shaft 19 passes through the shell 2 and extends to the outside of the shell 2, and a nut 20 is sleeved on the outer wall of the adjusting shaft 19 located outside the shell 2. The force of the spring spring 18 can only retract the drawstring 4 in the absence of external force, and its force is much smaller than the force of opening the patient's lips; by setting the spring spring 18 8. The adjusting shaft 19 is used in conjunction with the nut 20, etc. When in use, the spring spring 18 stores energy. When the device is not in use, the mouth supporter body 1 is removed, the inclined block 16 is pulled open, and the spring spring 18 can drive the winding shaft 3 to rotate, so that the winding shaft 3 automatically reels the drawstring 4, etc., and when in use, when the force of the spring spring 18 is relaxed, the nut 20 can be loosened, and then the adjusting shaft 19 is rotated, so that the adjusting shaft 19 drives one end of the spring spring 18 to readjust the force of the spring spring 18.

[0035] Furthermore, one end of the winding shaft 3 is rotatably connected to the adjusting shaft 19 ; by setting one end of the winding shaft 3 to be rotatably connected to the adjusting shaft 19 , the stability of one end of the winding shaft 3 can be increased.

[0036] Furthermore, one end of the connecting belt 10 is wrapped in the transparent cover 8, and a marking line 21 is set at the end of the connecting belt 10 located in the transparent cover 8; by setting the marking line 21, the position of the marking line 21 on the scale line 9 can be used to judge the length by which the elastic belt 5 is stretched.

[0037] Furthermore, a cushion 22 is fixedly connected to one side wall of the shell 2, and a bandage ring 23 is fixedly connected to one side wall of the cushion 22; by arranging the cushion 22 and the bandage ring 23 for use in conjunction, it is convenient to wear the shell 2 and other components. When in use, the bandage ring 23 is fixedly put on the patient's head.

[0038] Furthermore, a partition plate 24 is fixedly connected to the inner wall of the shell 2, and the winding shaft 3 and the rotating shaft 12 are both arranged through the partition plate 24; by setting the partition plate 24, the drawstring 4 can be separated, and the drawstring 4 can be separated into a separate cavity to protect the drawstring 4.

[0039] In the present invention, when in use, the device is put on the user's head through the bandage ring 23 to fix the shell 2 and other components, and then the mouth supporter body 1 is placed in the patient's mouth so that the mouth supporter body 1 opens the patient's lips, and then the inclined block 16 is pulled open, and then the pull head 6 is pulled, and the button 7 on one side of the pull head 6 is inserted into the connecting hole 11, and then the rotating shaft 12 can be rotated, and the rotating shaft 12 drives the first gear 13 to rotate, and the rotating first gear 13 drives the second gear 14 to rotate, and the rotating second gear 14 rotates the winding shaft 3, so that the winding shaft 3 winds around the drawstring 4, and the wound drawstring 4 pulls the elastic band 5 and the pull head 6, and then the pull head 6 pulls the connecting band 10 and the mouth supporter body 1, and then the mouth supporter body 1 opens the patient's lips. By opening the patient's lips in this way, the force of the device pulling the patient's lips can be adjusted, so that for different patients, the device can be adjusted to a force suitable for opening the patient's lips;

[0040] When in use, if the device is adjusted to open the patient's lips with too much force, it is only necessary to pull out the oblique stopper 16, and then the mouth support body 1 can be quickly released from pulling the patient's lips, so as to reduce the damage caused by the excessive force of opening the patient's lips;

[0041] At the same time, when the mouth support device body 1 is pulled by the elastic band 5 etc. to open the patient's lips, the force of pulling the patient's lips can be observed through the deformation of the elastic band 5. When the drawstring 4 is wound around the winding shaft 3, one end of the drawstring 4 will pull the elastic band 5 etc., causing the elastic band 5 etc. to deform, while one end of the transparent sleeve 8 is not fixed. Therefore, when the elastic band 5 is deformed, the transparent sleeve 8 will not be deformed. The scale line 9 on the transparent sleeve 8 can be used to observe and judge the length of the elastic band 5 being pulled, and the force of the device pulling the mouth support device body 1 and the patient's lips through the elastic band 5 etc. can be judged. In this way, the force of pulling the mouth support device body 1 and the patient's lips can be intuitively seen, which can facilitate the user's adjustment.

[0042] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0043] 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.
