Description

Technical Field

[0001] This invention relates to the field of acupuncture technology, specifically to an acupuncture positioning device. Background Technology

[0002] During acupuncture, the practitioner must manually insert the needle into the acupoint. Accurate needle placement requires a high level of experience and skill from the practitioner. Incorrect insertion angles or hand tremors can lead to misalignment of the acupoint. Incorrect needle placement necessitates repeated needling, undoubtedly increasing the patient's discomfort. Therefore, accurate needle positioning is essential during acupuncture.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN114652607A discloses a positioning-assisted needle insertion device for traditional Chinese medicine acupuncture. The device comprises an outer shell and an inner shell. A top cover is installed inside the outer shell, and the inner shell is fixedly connected to the bottom surface of the top cover. First sliding grooves are formed on both sides of the outer shell, and a second sliding groove is formed on the other side. A slider is slidably connected within the first sliding groove. A fixed shell is installed between the two sliders. A first spring is fixedly connected between the top cover and the sliders. A first lead screw is provided between the top cover and the sliders, and a limiting block is threaded onto the first lead screw. A first connecting post is fixedly connected to the slider. A limiting plate is rotatably connected to the bottom surface of the top cover. A second spring is fixedly connected between the limiting plate and the inner wall of the outer shell. A sliding rod is fixedly connected to the limiting plate. A fixed plate is installed inside the fixed shell, and a third sliding groove is formed at one end of the fixed plate. A second lead screw is rotatably connected inside the fixed shell, and a fastening block is threaded onto the second lead screw. This device facilitates the fixation of the acupuncture needle, preventing instability during acupuncture and thus ensuring accurate acupoint placement.

[0004] While the aforementioned needle insertion device facilitates the positioning and insertion of acupuncture needles, we have found certain shortcomings in practical applications, such as:

[0005] The change in puncture angle also has a great impact on the acupuncture effect. However, the above-mentioned needle insertion device is not convenient for adjusting the needle insertion angle; at the same time, the above-mentioned needle insertion device cannot disinfect the silver needles.

[0006] Based on this, we propose an acupuncture positioning device. Summary of the Invention

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the present invention provides an acupuncture positioning device with the following beneficial effects:

[0032] 1. In this acupuncture positioning device, the needle body passes through the needle cylinder, and its end is located at the rotating ball. The needle handle is located inside the moving cylinder. Twisting the rotating cylinder can make the threaded cylinder rotate. The threaded cylinder rotates and gradually moves downward, driving several clamping pieces to move downward. The clamping pieces slowly close under the action of the convex ring, thereby clamping the needle handle and effectively fixing the position of the needle handle, so that the moving cylinder can drive the needle handle to move.

[0033] 2. In this acupuncture positioning device, during acupuncture, the bottom ring is placed on the human body, and the needle groove of the rotating ball is aligned with the position to be acupunctured. After alignment, the moving cylinder inside the syringe moves down, which in turn moves the needle body down. The needle body moves down and passes through the needle groove, thus enabling acupuncture. The needle groove of the rotating ball is aligned with the acupoint to be acupunctured. The position of the syringe on the arc beam can be adjusted to arbitrarily select the needle angle. At the same time, the needle tip can always be aligned with the needle groove, which improves the success rate of acupuncture and reduces the patient's pain.

[0034] 3. This acupuncture positioning device locks the needle handle position by rotating the rotating cylinder, while disinfectant is sprayed from the annular tube (at which time the needle tip is located in the needle groove), thereby disinfecting the needle tip, improving the safety of acupuncture and effectively avoiding cross-infection of bacteria.

[0048] Example 1:

[0049] Please see Figure 1 -

[0050] Figure 7 An acupuncture positioning device includes a bottom ring 1. Vertical frames 3 are fixedly installed on both the left and right sides of the top of the bottom ring 1. An arc-shaped beam 4 is fixedly installed between the two vertical frames 3. A needle cylinder 5 is slidably mounted on the arc-shaped beam 4. A rotating ball 9 is fixedly connected to the bottom of the needle cylinder 5 via a connecting rod 8. The rotating ball 9 is rotatably positioned between two positioning seats 11. Both positioning seats 11 are fixedly installed on the bottom ring 1 via positioning rods 12. Figure 5 As shown, a needle handle 6 and a needle body 7 are also provided, which are connected to each other. The needle handle 6 and the needle body 7 are inserted into the syringe 5, as shown. Figure 3As shown, a needle groove 10 corresponding to the needle body 7 is vertically opened inside the rotating ball 9, and an annular tube 31 for spraying disinfectant is provided inside the needle groove 10.

[0051] In this embodiment, a movable cylinder 19 is provided inside the syringe 5, and the needle handle 6 is fixedly and detachably disposed inside the movable cylinder 19.

[0052] During acupuncture, the bottom ring 1 is placed on the human body, and the needle groove 10 of the rotating ball 9 is aligned with the acupuncture point. After alignment, the moving cylinder 19 inside the syringe 5 moves down, which in turn moves the needle body 7 down. The needle body 7 moves down and passes through the needle groove 10, thus enabling acupuncture. The needle groove 10 of the rotating ball 9 is aligned with the acupuncture point. The needle angle can be arbitrarily selected by adjusting the position of the syringe 5 on the arc beam 4. At the same time, the needle tip of the needle body 7 can always be aligned with the needle groove 10, which improves the success rate of acupuncture and reduces the patient's pain.

[0053] like Figure 4 As shown, a slide plate 13 is fixedly installed on the back of the syringe 5. The slide plate 13 is slidably disposed in the arc groove 14. The arc groove 14 is opened on the arc beam 4. A limiting plate 15 is also fixedly installed on the slide plate 13. The limiting plate 15 is slidably disposed in the limiting groove 16. The limiting groove 16 is opened on the inner wall of the arc groove 14.

[0054] The sliding arrangement of the slide plate 13 in the arc groove 14 and the sliding arrangement of the limiting plate 15 in the limiting groove 16 facilitate the adjustment of the position of the syringe 5 on the arc beam 4.

[0055] In this embodiment, the arc-shaped beam 4 is a beam with the rotating ball 9 as its center, and it rotates around the rotating ball 9.

[0056] A threaded rod is threadedly connected to the tail end of the slide plate 13. A conical column 17 is fixedly connected to the end of the threaded rod. A rotating column 18 is fixedly connected to the end of the conical column 17. Rotating the rotating column 18 can cause the threaded rod to move into the slide plate 13 or gradually disengage from the slide plate 13. When the threaded rod moves into the slide plate 13, the conical column 17 will be locked between the two inner walls of the arc groove 14. Thus, by locking the conical column 17 between the two inner walls of the arc groove 14, the slide plate 13 can be limited, thereby limiting the syringe 5.

[0057] like Figure 1 and Figure 2 As shown, an annular rubber pad 2 is also fixedly installed at the bottom of the bottom ring 1. The friction of the annular rubber pad 2 makes it easier for the bottom ring 1 to be placed on the human body.

[0058] In this embodiment, the needle handle 6 is detachably fixed inside the movable cylinder 19, specifically:

[0059] like Figure 6 and Figure 7As shown, a base plate 32 is fixedly installed at the bottom of the movable cylinder 19, a right side block 33 is fixedly installed on the right side of the base plate 32, the right side block 33 is slidably disposed in the sliding groove 34, the sliding groove 34 is opened on the inner wall of the right side of the syringe 5, and a left side block 35 is fixedly installed on the left side of the base plate 32, the left side block 35 is slidably disposed in the through groove 36, the through groove 36 is opened on the inner wall of the left side of the syringe 5;

[0060] By sliding the right block 33 in the sliding groove 34 and the left block 35 in the through groove 36, the entire moving cylinder 19 and the base plate 32 can move smoothly up and down in the syringe 5, and can be positioned (maintain position) by using friction.

[0061] In this embodiment, the inner wall of the movable cylinder 19 is threadedly connected to a threaded cylinder 20, the top of the threaded cylinder 20 is fixedly mounted with a rotating cylinder 21, the bottom of the threaded cylinder 20 is evenly provided with a plurality of elastic clamping pieces 22, the inner wall of the movable cylinder 19 is fixedly provided with a protruding ring 23 for pushing the clamping pieces 22, and a recessed portion 24 for engaging the end of the clamping piece 22 is formed on the needle handle 6.

[0062] The needle body 7 passes through the syringe 5, and its end is located at the rotating ball 9. The needle handle 6 is located inside the moving cylinder 19. Twisting the rotating cylinder 21 can make the threaded cylinder 20 rotate. The threaded cylinder 20 rotates and gradually moves downward, driving several clamping pieces 22 to move downward. The clamping pieces 22 move downward and slowly close under the action of the convex ring 23, thereby clamping the needle handle 6 and effectively fixing the position of the needle handle 6, so that the moving cylinder 19 can drive the needle handle 6 to move.

[0063] Example 2:

[0064] Please see Figure 5 and Figure 6 Based on Embodiment 1, a pressure plate 25 is also provided inside the movable cylinder 19. A pressure rod 27 is fixedly installed at the bottom of the pressure plate 25. A first piston 28 is fixedly connected to the bottom end of the pressure rod 27. The first piston 28 is movably disposed in the movable cavity 29. The movable cavity 29 is opened in the bottom plate 32. One side of the movable cavity 29 is connected to the annular pipe 31 through a connecting pipe 30. A liquid outlet check valve is provided on the connecting pipe 30. The other side of the movable cavity 29 is connected to the inner cavity through an inlet pipe. The inner cavity is opened inside the bottom plate 32. An inlet check valve is provided on the inlet pipe. In this embodiment, a first spring 26 is also sleeved on the pressure rod 27. The first spring 26 is fixedly disposed between the bottom of the pressure plate 25 and the top of the bottom plate 32.

[0065] Thus, while rotating the rotating cylinder 21 to lock the position of the needle handle 6, the clamping plate 22 moves down and retracts, which also pushes the pressure plate 25 down. The downward movement of the pressure plate 25 drives the first piston 28 down through the pressure rod 27 (and also compresses the first spring 26). The downward movement of the first piston 28 squeezes out the disinfectant in the movable cavity 29 through the connecting pipe 30. The squeezed disinfectant is discharged through the annular pipe 31, thereby disinfecting the needle tip of the needle body 7, improving the safety of acupuncture and effectively avoiding cross-infection of bacteria.

[0066] Conversely, when the clamp 22 moves upward, the pressure plate 25 will reset under the elastic force of the first spring 26, and then drive the first piston 28 to reset through the pressure rod 27. The reset first piston 28 draws the disinfectant in the inner cavity into the movable cavity 29 through the liquid inlet pipe for the next use.

[0067] In this embodiment, the connecting tube 30 extends from the right block 33, passes through the sliding groove 34, and then passes through the wall of the syringe 5, the connecting rod 8 and the rotating ball 9 in sequence to connect with the annular tube 31. The section of the connecting tube 30 located in the sliding groove 34 is elastic.

[0068] Example 3:

[0069] Please see Figure 8 -

[0070] Figure 12 Based on Embodiment 2, a partition 51 is also fixedly installed on the inner wall of the syringe 5. A disinfection space is formed between the partition 51 and the inner bottom wall of the syringe 5. A disinfection tube 50 is installed in the disinfection space. The disinfection tube 50 sprays disinfectant. The sprayed disinfectant fills the disinfection space. The needle 7 passes through the disinfection space and can also be disinfected by the sprayed or evaporated disinfectant.

[0071] like Figure 11 As shown, a groove is provided on the inner bottom wall of the syringe 5 for the needle body 7 to pass through. A conical plate 52 is fixedly installed on the top of the groove, and a conical soft sleeve 53 is fixedly installed on the top of the conical plate 52. The conical soft sleeve 53 is tightly bound to the needle body 7, thereby ensuring the sealing of the groove.

[0072] In this embodiment, a collection bottle can be detachably connected to the bottom of the syringe 5, through which the used disinfectant can be collected, and the conical plate 52 facilitates the discharge of the disinfectant.

[0073] like Figure 10As shown, the disinfection tube 50 is connected to the stopper 47 via the infusion tube 49. The infusion tube 49 is equipped with a one-way discharge valve. A second piston 46 is movably installed inside the stopper 47. A push plate 45 is fixedly connected to the left side of the second piston 46 via a horizontal shaft. A second spring 48 is fixedly installed between the right side of the second piston 46 and the inner wall of the stopper 47. The stopper 47 is also connected to the liquid storage tank 59 via the liquid supply tube. The liquid storage tank 59 is fixedly installed on the right side of the syringe 5. A one-way inlet valve is installed on the liquid supply tube.

[0074] The movement of the push plate 45 via the horizontal axis can drive the second piston 46 to move left and right. When the second piston 46 moves to the right, it will compress the second spring 48 on the one hand, and squeeze the disinfectant in the stopper 47 through the infusion tube 49 on the other hand, and then spray it out through the disinfection tube 50.

[0075] Conversely, when the second piston 46 moves to the left, it draws the disinfectant from the reservoir 59 into the stopper 47 through the supply pipe, thus facilitating the next use.

[0076] In this embodiment, the movement of the push plate 45 is achieved by the up-and-down movement of the moving cylinder 19, specifically:

[0077] A bearing column 42 is fixedly installed at the end of the left side block 35. A sliding column 41 is movably and telescopically installed inside the bearing column 42. The sliding column 41 is slidably installed in the arc-shaped guide groove 39 and the vertical guide groove 40 on the rotating column 38. The arc-shaped guide groove 39 is spirally opened along the peripheral wall of the rotating column 38. The vertical guide groove 40 gradually becomes shallower from top to bottom along the axial direction of the rotating column 38. Furthermore, the top and bottom ends of the arc-shaped guide groove 39 coincide with the top and bottom ends of the vertical guide groove 40, respectively. Therefore, when the bearing... When the support column 42 and the sliding column 41 (relative to the rotating column 38) move from top to bottom, the sliding column 41 will slide along the vertical guide groove 40 (because the top of the vertical guide groove 40 is deeper than the top of the arc-shaped guide groove 39), while when the support column 42 and the sliding column 41 (relative to the rotating column 38) move from bottom to top, the sliding column 41 will slide along the arc-shaped guide groove 39 (because the bottom of the vertical guide groove 40 is shallower than the bottom of the arc-shaped guide groove 39), thereby driving the rotating column 38 to rotate;

[0078] Therefore, when the moving cylinder 19 moves from top to bottom to move the needle body 7 down for acupuncture, the rotating column 38 will not rotate. Conversely, when the moving cylinder 19 moves from bottom to top to move the needle body 7 up to remove the needle, the rotating column 38 will rotate.

[0079] The top of the rotating column 38 is rotatably mounted on the inner top wall of the side cabinet 37 via a top shaft, and the bottom of the rotating column 38 is rotatably mounted on the inner bottom wall of the side cabinet 37 via a bottom shaft 43. An eccentric wheel 44 is also fixedly mounted on the bottom shaft 43. The eccentric wheel 44 is movably mounted on the push plate 45. Thus, when the rotating column 38 rotates, it will drive the eccentric wheel 44 to rotate via the bottom shaft 43. The rotation of the eccentric wheel 44 can cyclically push the push plate 45 to move.

[0080] In this embodiment, as Figure 12 As shown, a support plate 54 is also provided in the sliding groove 34. The support plate 54 plays a blocking and limiting role. By adjusting the position of the support plate 54, the deepest downward movement distance of the moving cylinder 19 can be adjusted, thereby adjusting the needle insertion depth of the needle body 7.

[0081] The tray 54 is fixedly connected to the nut 55 via a connecting block. The inner wall of the nut 55 is threaded with a lead screw 56. The lead screw 56 is rotatably mounted inside the regulating cabinet 57. The regulating cabinet 57 is fixedly mounted on the outer wall of the syringe 5. The bottom end of the lead screw 56 extends to the outside of the regulating cabinet 57 and is fixedly connected to a knob 58.

[0082] Turning knob 58 causes lead screw 56 to rotate. The rotation of lead screw 56 causes the threaded nut 55 on its outer wall to move up and down. The up and down movement of threaded nut 55 drives the support plate 54 to move up and down through the connecting block.
