Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an acupuncture device with adjustable acupuncture depth. Background Technology

[0002] Acupuncture is widely used in medicine, including acupuncture. However, beginners often cannot accurately determine the needle insertion point due to lack of skill, preventing the needle from directly entering the acupoint. In many cases, beginners need a fixator to help secure the metal needle so that they can insert it directly into the patient's acupoint.

[0003] Existing adjustable acupuncture devices all use manual needle pushing. However, in acupuncture, due to the large number of metal needles required, manual needle pushing becomes inefficient. When using a motor for depth adjustment, a malfunction in the electronic components can cause excessive deviation in the motor's travel, potentially harming the patient. Summary of the Invention

The outer tube 20 is connected to the inner tube 101. A movable sleeve 21 is fitted onto the left end of the outer tube 20. An inner tube 7 runs through the inner tube 20. A middle tube 6 is fixedly connected to the left end of the L-shaped shell 101. A limiting ring 5 is fitted onto the surface of the middle tube 6. A first spring 4 is fitted onto the surface of the middle tube 6 between the movable sleeve 21 and the limiting ring 5. The inner tube 7 is fitted inside the outer tube 20. The left end of the inner tube 7 passes through the movable sleeve 21 and the middle tube 6 sequentially to the left end of the L-shaped shell 101. A U-shaped magnet 11 is provided on the left side surface of the U-shaped shell 16. When the shell 2 is rotated open, it can prevent the placement of metal needles; when the shell 2 is rotated closed, metal needles can be placed. The U-shaped magnet 11 below the U-shaped shell 16 ensures that the placed metal needles will not easily fall out. The metal needles are generally made of stainless steel, which can be magnetically attracted.

[0033] In this embodiment, a semicircular block 9 is fitted on the right side of the movable sleeve 21. A transmission column 8 is connected to both sides of the semicircular block 9. Slide grooves 10 are formed on the inner and outer walls of the rotating shell 2. The ends of the transmission columns 8 are engaged inside the slide grooves 10. The slide grooves 10 on both sides of the inner wall are centrally symmetrically distributed (e.g., ...). Figure 2As shown), once the rotating shell 2 rotates 180° clockwise, it will pull the movable sleeve 21 to the right. When the rotating shell 2 rotates 180° counterclockwise again, it will pull the movable sleeve 21 to the left. A fixing ring 12 is fixedly connected inside the outer shell 1 and to the surface of the U-shaped shell 16. An arc groove 51 is formed on the surface of the fixing ring 12, and a connecting rod 52 passes through the arc groove 51.

[0034] In this embodiment, a fixing frame 27 is fixedly connected to the inside right side of the outer casing 1. A second rod 24 is inserted through the inside of the second connecting block 17. The right end of the second rod 24 extends to the right side of the fixing frame 27. A third bevel gear 23 is fitted on the left side surface of the second rod 24. A second bevel gear 22 is fitted on the left side surface of the first rod 19. When the second bevel gear 22 is in the right-side position, it meshes with the third bevel gear 23. A pushing block 49 is movably arranged inside the second through groove 48. A top through rod 44 is inserted through the top right end of the pushing block 49. A pushing block 49 is inserted through the bottom inside the pushing block 49. 4. The right end of the push rod 46 is fixedly connected to the main connecting plate 34 and the auxiliary connecting plate 45. The surface of the first rod 19 and the right side of the main connecting plate 34 are fitted with the first gear 35. The bottom end of the main connecting plate 34 is fixedly connected to the push frame 33. The bottom end of the push frame 33 passes through the bottom end of the first gear 35 and is attached to the right side of the first gear 35. The surface of the first rod 19 is provided with a pin groove. The first gear 35 is slidably connected to the first rod 19 through the pin groove. The bottom end of the push block 49 is magnetic. After the metal needle is placed inside the U-shaped shell 16, the needle tip can be attracted to the push block 49, and its needle tip will face the middle tube 6.

[0035] In this embodiment, an upper threaded rod 41 and a lower threaded rod 43 are rotatably disposed between the main connecting plate 34 and the auxiliary connecting plate 45. A fourth transmission plate 40 is sleeved on the right end of the upper threaded rod 41, and a second gear 36 and a second transmission plate 37 are sleeved on the right end of the lower threaded rod 43. A second transmission belt 39 is sleeved on the surface of the second transmission plate 37 and the fourth transmission plate 40. The second gear 36 meshes with the first gear 35. A drive frame 42 is sleeved on the surface of the upper threaded rod 41 and the lower threaded rod 43, and the drive frame 42 is connected to the upper threaded rod 41 and the lower threaded rod 43. All three are threaded connections. A threaded long rod 25 is threaded through the center of the drive frame 42, and the drive frame 42 is threadedly connected to the threaded long rod 25. The left end of the threaded long rod 25 passes through the auxiliary connecting plate 45 and is rotatably connected to the right surface of the U-shaped shell 16. The right end of the threaded long rod 25 passes through to the right side of the fixed frame 27 and is fitted with a third transmission plate 38. A drive motor 28 is fixedly installed on the top of the fixed frame 27. The output shaft of the drive motor 28 is fitted with a first transmission plate 29. A first transmission belt 26 is fitted on the surface of the first transmission plate 29 and the third transmission plate 38. The first transmission belt 26 and the second transmission belt 39 are both synchronous belts, which ensures that slippage will not occur during transmission.

[0036] In this embodiment, a battery 30 is provided inside the right side of the L-shaped shell 101, a control box 31 is installed inside the L-shaped shell 101 and above the battery 30, and a switch 32 is provided on the right side surface of the L-shaped shell 101.

[0037] The working principle of this device is as follows: When acupuncture is needed, simply rotate the knob 3. Through the drive of the first rod 19 and the first bevel gear 13, the semicircular rack 50 drives the rotating shell 2 to rotate 180° (the process of which is as follows). Figure 5 The middle becomes like Figure 2 (in the middle), at this time, the first through groove 47 and the second through groove 48 on the rotating shell 2 are aligned, and the metal needle can be placed inside the U-shaped shell 16 through the first through groove 47 and the second through groove 48. Since the pushing block 49 and the U-shaped magnet 11 are both magnetic, the metal needle can be attracted inside the U-shaped shell 16 to prevent it from falling.

[0038] When the metal needle needs to be inserted into the skin, simply place the left beveled end of the outer casing 1 against the skin and activate the drive motor 28 via switch 32. The drive motor 28 then drives the threaded rod 25 to rotate via the first transmission disc 29, the first transmission belt 26, and the third transmission disc 38. As the threaded rod 25 rotates, the drive frame 42 on its surface will move to the left (e.g., ...). Figure 3As shown), the drive frame 42, which moves to the left, will drive the main connecting plate 34 and the auxiliary connecting plate 45 to move to the left through the upper threaded rod 41 and the lower threaded rod 43. In this way, the top through rod 44 and the push rod 46 will drive the push block 49 to move to the left. At this time, the push block 49, which moves to the left, can insert the metal needle into the skin.

[0039] When the drive motor 28 retracts the push block 49, the push block 49 can be reset by pulling the knob 3 to the right and rotating it. That is, after pulling the knob 3 to the right, the second bevel gear 22 will mesh with the third bevel gear 23. Then, rotating the knob 3 will drive the second rod 24 to rotate. The second rod 24 can then drive the second transmission disc 37 and the fourth transmission disc 40 to rotate through the first gear 35 and the second gear 36. The upper threaded rod 41 and the lower threaded rod 43 will be driven, thereby adjusting the initial position of the push block 49 without changing the stroke of the drive motor 28.

[0040] All electrical components mentioned in this article are real-world electrical components.

[0041] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
