Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a dental film positioner. BACKGROUND

[0002] The dental film is a special film used in the field of oral medicine, which mainly records the images of teeth, periodontal tissue and jaw bone through X-ray irradiation during dental diagnosis and treatment, so as to diagnose the dental health status of patients, such as finding caries, pulp lesion, periapical disease, alveolar bone absorption, dental development abnormalities, impacted teeth, jaw tumor and the like. The dental film needs to use a positioner during use, and the patient only needs to bite the positioner, without the need for the doctor to hold it by hand.

[0003] The existing positioner cannot be adjusted in position, and when the upper and lower teeth of the left and right oral cavities are photographed, different angle positioners need to be replaced, thereby increasing the use cost and the operation is relatively cumbersome. Therefore, a dental film positioner is proposed. SUMMARY

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1-8 As shown, this embodiment of the invention provides a dental film locator, including a positioning component 1. The positioning component 1 includes a lens ring 10, a fixing block 11, a Z-shaped support plate 12, an L-shaped clamping plate 13, a movable block 14, two fixing rods 15, two protruding limiting blocks 16, two rotation limiting mechanisms 17, a clamping fixing plate 18, and a second rod body 19. The fixing block 11 is disposed on the upper surface of the lens ring 10, and the fixing block 11 and the lens ring 10 are integrally formed. An operating groove 2 is formed on one side of the fixing block 11. The movable block 14 is rotatably connected to the inner wall of the operating groove 2, and a slot 3 is formed on one side of the movable block 14. The two fixing rods 15 are symmetrically arranged on the inner wall of the operating groove 2. A protruding limiting block 16 is disposed at one end of a corresponding fixing rod 15. The outer wall of the fixing rod 15 is attached to the inner wall of the slot 3. The protruding limiting block 16 is attached to the movable block 14. A U-shaped support plate 12 is disposed on the upper surface of the movable block 14 and is integrally formed with the movable block 14. A second rod body 19 is disposed on one side of the U-shaped support plate 12 and is integrally formed with the U-shaped support plate 12. Two rotation limiting mechanisms 17 are rotatably connected to the second rod body 19 and are symmetrically disposed on the L-shaped clamping plate 13. A clamping fixing plate 18 is disposed on the inner wall of the L-shaped clamping plate 13 and is integrally formed with the L-shaped clamping plate 13.

[0021] In this embodiment, specifically, the rotation limiting mechanism 17 includes a U-shaped limiting plate 170, a rotating plate 171, and several friction protrusions 172. The upper surface of the rotating plate 171 is provided with a second circular through hole 6, and the second rod 19 passes through the second circular through hole 6. The outer wall of the rotating plate 171 is provided with a U-shaped through hole 7, and the U-shaped limiting plate 170 passes through the U-shaped through hole 7. Several friction protrusions 172 are evenly arranged on the outer wall of the U-shaped limiting plate 170. With the above arrangement, the doctor drives the U-shaped limiting plate 170 to move relative to each other through the friction protrusions 172, so that the U-shaped limiting plates 170 on the two rotation limiting mechanisms 17 are in contact with the Z-shaped support plate 12, which facilitates the fixing of the positions of the rotating plate 171, the L-shaped clamping plate 13, and the clamping fixing plate 18. The friction protrusions 172 are used to increase the friction force of the U-shaped limiting plate 170 during operation.

[0022] In this embodiment, specifically, the rotation limiting mechanism 17 further includes a sealing ring 173, wherein the sealing ring 173 is disposed on the inner wall of the U-shaped through hole 7, and the U-shaped limiting plate 170 is attached to the inner wall of the sealing ring 173. The sealing ring 173 is used to enhance the friction between the sealing ring 173 and the U-shaped limiting plate 170, and to limit the position of the U-shaped limiting plate 170.

[0023] In this embodiment, specifically, the upper surface of the movable block 14 is provided with a first circular through hole 4, and the inner wall of the operating through groove 2 is provided with a first rod 5. The first rod 5 passes through the first circular through hole 4. The movable block 14 is provided to drive the first circular through hole 4 to rotate on the first rod 5, thereby assisting the movable block 14 to rotate.

[0024] In this embodiment, the protruding limiting block 16 is made of silicone.

[0025] In this embodiment, specifically, the sealing ring 173 is made of silicone.

[0026] In operation, the present invention employs a fixing rod 15 and a protruding limiting block 16 that engage with the slot 3 to fix the position of the movable block 14. Subsequently, the doctor uses friction protrusions 172 on the two rotating limiting mechanisms 17 to drive the U-shaped limiting plate 170 to move relative to each other. The sealing ring 173 enhances the friction between itself and the U-shaped limiting plate 170, limiting the position of the U-shaped limiting plate 170 and ensuring it fits snugly against the Z-shaped support plate 12, facilitating rotation. The positions of plate 171, L-shaped clamping plate 13, and clamping fixation plate 18 are fixed. After the doctor moves the clamping fixation plate 18 away from the L-shaped clamping plate 13, the dental film is placed between the L-shaped clamping plate 13 and the clamping fixation plate 18. The doctor releases the clamping fixation plate 18 so that the clamping fixation plate 18 fixes the dental film on the L-shaped clamping plate 13 and the clamping fixation plate 18. Then the doctor places the zigzag support plate 12, L-shaped clamping plate 13, two rotation limit mechanisms 17, clamping fixation plate 18, and dental film on the patient's left upper and lower teeth for occlusal fixation.

[0027] When examining the patient's upper and lower right teeth, the dentist holds the movable block 14 and rotates it on the fixed block 11 to change the position of the U-shaped support plate 12. The slot 3 on the movable block 14 moves to another fixed rod 15 and another protruding limiting block 16. The protruding limiting block 16 is squeezed out of the slot 3, which is used to fix the position of the movable block 14. Afterward, the dentist drives the U-shaped limiting plate 170 to move repulsively through the friction protrusions 172 on the two rotating limiting mechanisms 17. The sealing ring 173 is used to enhance the friction between the U-shaped limiting plate 170 and limit the position of the U-shaped limiting plate 170, so that the U-shaped limiting plate 170 on the two rotating limiting mechanisms 17 moves from the U-shaped support plate 12. The support plate 12 is moved out, so that the U-shaped limiting plate 170 moves into the U-shaped through hole 7, which makes it easier for the doctor to hold the L-shaped clamping plate 13 and drive the clamping fixing plate 18 and the film through the second circular through hole 6 on the rotating plate 171 to rotate on the second rod 19. Then, the doctor drives the U-shaped limiting plate 170 to move relative to each other through the friction protrusions 172 on the two rotating limiting mechanisms 17. The sealing ring 173 is used to enhance the friction between the U-shaped limiting plate 170 and to limit the position of the U-shaped limiting plate 170, so that the U-shaped limiting plate 170 on the two rotating limiting mechanisms 17 fits with the Z-shaped support plate 12, which makes it easier to fix the position of the rotating limiting mechanism 17 and the clamping fixing plate 18.

[0028] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
