Description

Technical Field

[0001] The invention belongs to the technical field of acupuncture equipment, and in particular relates to an acupuncture device for blind method. Background Art

[0002] In medical research and clinical practice, double-blind trials, as a rigorous clinical trial research method, are widely used to evaluate the effectiveness of drugs, therapies, or interventions. The core characteristic of a double-blind trial is that neither the experimenter nor the participants know which participants are receiving the actual treatment (experimental group) or the placebo (control group), thereby minimizing the impact of subjective bias and the placebo effect on clinical research results.

[0003] However, achieving acupuncture blindness in double-blind trials is a challenge. Traditional acupuncture therapy relies on inserting needles into specific acupuncture points and manipulating them to produce therapeutic effects. During this process, both the experimenter and the participant can directly feel the needles and the stimulation, making true double-blindness difficult to achieve.

[0004] Existing therapeutic acupuncture devices have the problem of uncontrollable acupuncture depth, and existing placebo acupuncture devices have problems such as lack of concealment and large differences in the pricking sensation. These differences may lead to changes in the psychological expectations, reactions and subjective evaluations of experimental participants, thereby affecting the accuracy of research results.

[0005] Therefore, developing a therapeutic acupuncture device that can achieve adjustable control of acupuncture depth, better simulate the real acupuncture sensation, and achieve a higher degree of concealment of the placebo acupuncture device, while also being able to set the acupuncture depth, is of great significance for improving the accuracy of acupuncture therapy evaluation in double-blind experiments.

[0024] The present invention provides an acupuncture device for blinded treatment, which is intended to simulate acupuncture treatment in double-blind clinical studies, thereby facilitating scientific evaluation of the efficacy of acupuncture and achieving controllable acupuncture depth. It is used to solve the problems of the existing placebo acupuncture devices, such as poor concealment, large differences in pricking sensation, and varying acupuncture depths.

[0025] like Figure 1 and Figure 9 As shown, an acupuncture device for blind method includes a treatment needle set 1 and a placebo needle set 2. The treatment needle set 1 has a therapeutic effect, while the placebo needle set 2 has no therapeutic effect.

[0026] like Figure 1 As shown, the treatment needle set 1 includes a first needle tube 3, a first descending assembly 4, a first depth adjustment assembly 5, a first resistance drop assembly 6 and a treatment needle 7. The first depth adjustment assembly 5, the first descending assembly 4 and the treatment needle 7 are arranged in the first needle tube 3 from top to bottom. The first depth adjustment assembly 5 is connected to the first descending assembly 4, and the top of the treatment needle 7 is fixedly connected to the first descending assembly 4. The first descending assembly 4 drives the treatment needle 7 to move downward in the first needle tube 3.

[0027] The first drop-off assembly 6 is disposed within the first needle tube 3, below the first descender assembly 4. This assembly is configured to adjust the position of the first descender assembly 4 within the first needle tube 3 to control the descending distance of the treatment needle 7. In practice, the depth of penetration of the treatment needle 7 into the skin varies depending on the intended treatment. To meet varying needs, the penetration depths can generally be set to 0.5 inch, 1 inch, and 1.5 inches.

[0028] like Figure 2 and Figure 3As shown, for example, the first needle tube 3 can be cylindrical, and the top and bottom of the first needle tube 3 are both open. The first needle tube 3 is provided with a bayonet 8 that penetrates the tube wall at the position of the first landing component 4, and the outer wall of the first needle tube 3 is provided with an elastic top-pressing portion 9 at the bayonet 8. The upper end of the elastic top-pressing portion 9 is fixedly connected to the outer wall of the first needle tube 3, and the inner side of the lower end of the elastic top-pressing portion 9 is provided with a first protrusion 10 that matches the bayonet 8. The first protrusion 10 can be moved in and out of the bayonet 8 by pressing or releasing the elastic top-pressing portion 9.

[0029] like Figure 3 and Figure 4 As shown, for example, the first landing assembly 4 includes a first reset tube 11 and a first connecting tube 12. The first reset tube 11 is arranged in the first needle tube 3 and is located below the first depth adjustment assembly 5. The first reset tube 11 and the first needle tube 3 are arranged concentrically. There is a first cavity between the first reset tube 11 and the first needle tube 3. The first reset tube 11 is sleeved on the outside of the first connecting tube 12. The outer wall of the first connecting tube 12 is provided with a limit ring 13 at both ends of the first reset tube 11. The outer diameter of the limit ring 13 is larger than the outer diameter of the first reset tube 11.

[0030] A first groove 14 is provided on the top tube wall of the first reset tube 11 near the bayonet 8, and a first buckle 15 is provided in the first groove 14. The first buckle 15 is strip-shaped, and the top of the first buckle 15 is fixedly connected to the top wall of the first groove 14. A second protrusion 16 matching the bayonet 8 is provided on the bottom outer side surface of the first buckle 15. When the second protrusion 16 is not under force, it passes through the first cavity and is clamped into the bayonet 8. When the elastic pressing part 9 is pressed, the first protrusion 10 at the lower end of the elastic pressing part 9 pushes the second protrusion 16 out of the bayonet 8, and the second protrusion 16 slides in the first cavity.

[0031] like Figure 2 and Figure 3 As shown, a strip-shaped reset groove 17 is provided on the lower part of the tube wall of the first needle tube 3, and the reset groove 17 extends along the axial direction of the first needle tube 3. A first reset rod 18 is provided on the first reset tube 11, and the first reset rod 18 passes through the first cavity and the reset groove 17. One end of the first reset rod 18 is fixedly connected to the outer side wall of the bottom of the first reset tube 11, and the other end of the first reset rod 18 is located outside the first needle tube 3. A ball handle is provided on the other end of the first reset rod 18 for easy operation.

[0032] The first reset tube 11 can be used to remove the needle by moving the reset lever upward. When not in use, the second protrusion 16 is located within the bayonet 8. By pressing the elastic pressing portion 9, the first descending assembly 4 moves downward within the first needle tube 3, completing the acupuncture operation. When the needle needs to be removed, the reset lever can be pushed upward to re-engage the second protrusion 16 within the bayonet 8.

[0033] like Figure 6As shown, the first needle tube 3 is provided with a color recognition port 19 on the upper part of the elastic pressing part 9 , and the first depth adjustment assembly 5 includes a first color recognition part 20 and a first spring 21 . The first color recognition part 20 is provided at the top opening of the first needle tube 3 .

[0034] like Figure 4 and Figure 5 As shown, the first color recognition part 20 includes a first color recognition body 22 and a first spring sleeve 23. The first color recognition body 22 is cylindrical. The bottom of the first color recognition body 22 is rotatably connected to the top opening of the first needle tube 3. The top of the first color recognition body 22 is located outside the first needle tube 3, so the user can rotate the first color recognition body 22.

[0035] A plurality of color zones are circumferentially arranged at the same height as the color recognition port 19 of the first needle tube 3 on the outer side surface of the first color recognition body 22. The colors of the plurality of color zones are different. The plurality of color zones are the same size as the color recognition port 19 on the first needle tube 3. Each color zone forms a small block-shaped protrusion structure. The plurality of color zones horizontally surround the first color recognition body 22. Rotating the first color recognition body 22 can make each color zone fall exactly into the color recognition port 19 of the first needle tube 3, and different acupuncture depths are selected according to different colors.

[0036] like Figure 4 、 Figure 5 and Figure 8 As shown, the first depth adjustment assembly 5 also includes a first internal gear 24, and the first descending assembly 4 also includes a first external gear 25. A blind hole 26 is axially disposed in the center of the bottom of the first color identification body 22. The top of the first spring sleeve 23 has an interference fit with the blind hole 26, securing the first spring sleeve 23 to the blind hole 26. The first internal gear 24 is sleeved outside the first spring sleeve 23 and located at the bottom of the first color identification body 22. A first external gear 25 is disposed at the top of the first connecting tube 12, meshing with the first internal gear 24. A disc-shaped first chassis 27 is fixedly disposed below the retaining ring 13 at the bottom of the first connecting tube 12. The top of the treatment needle 7 is fixedly connected to the bottom of the first chassis 27. When the first chassis 27 descends, it drives the treatment needle 7 downward and extends out of the first needle tube 3, thereby achieving the purpose of acupuncture.

[0037] The bottom of the first spring sleeve 23 is located in the first connecting cylinder 12 . The first spring 21 is disposed in the first spring sleeve 23 . The top of the first spring 21 contacts the bottom of the blind hole 26 . The bottom of the first spring 21 contacts the first chassis 27 .

[0038] like Figure 1 and Figure 4As shown, for example, a needle tube cover 28 is provided at the top opening of the first needle tube 3, and the needle tube cover 28 limits the first color recognition body 22 to the inside of the first needle tube 3. The first color recognition body 22 includes a first cylindrical portion 29 and a second cylindrical portion 30 connected in sequence from top to bottom. An annular positioning step 31 is provided at the connection between the first cylindrical portion 29 and the second cylindrical portion 30. The first cylindrical portion 29 passes through the needle tube cover 28, and the second cylindrical portion 30 is rotatably connected to the first needle tube 3. The blind hole 26 is provided at the bottom of the second cylindrical portion 30, and the bottom of the needle tube cover 28 is provided with an annular limiting step 32 matching the annular positioning step 31.

[0039] like Figure 7 As shown, for example, the first resistance drop component 6 includes an arc-shaped resistance drop portion 33, the outer wall surface of the arc-shaped resistance drop portion 33 is in contact with the inner wall surface of the first needle tube 3, and the arc-shaped resistance drop portion 33 is circumferentially provided with a plurality of step surfaces 331 of different heights, and the position of each step surface 331 corresponds to the position of a color zone on the first color recognition portion 20.

[0040] like Figure 8 As shown, an arc-shaped first stopper 34 is provided on the outer side of the first chassis 27 . The arc length of the cross section of the arc-shaped first stopper 34 is equal to the arc length of the step surface 331 , and each step surface 331 completely overlaps with the first stopper 34 in the vertical direction.

[0041] In the above technical solution, when not in use, the first reset tube 11 is also in a fixed state under the action of the limit rings 13 at both ends of the connecting tube, and the first spring 21 is in a compressed state. When in use, the first color recognition part 20 is rotated to align the color area of ​​the required acupuncture depth with the color recognition port 19. Different color areas represent different degrees of descent of the treatment needle 7, that is, different acupuncture depths. For example, red means that the first stopper 34 can be blocked by the highest step surface 331 of the arc-shaped resistance part 33, so it can only descend 0.5 inches, that is, the acupuncture depth is also 0.5 inches, while green means that the treatment needle 7 can descend 1 inch, that is, the acupuncture depth is also 1 inch, and purple means that the treatment needle 7 can descend 1.5 inches, that is, the acupuncture depth is also 1.5 inches.

[0042] Rotating the first color recognition unit 20, under the action of the first outer gear 25 and the first inner gear 24, can drive the first chassis 27 to rotate. At this time, the corresponding first stopper 34 will be located just above the step surface 331 corresponding to this color on the arc-shaped anti-drop portion 33. Pressing the elastic pressing portion 9 disengages the second protrusion 16 from the bayonet 8, and the first reset tube 11 loses its support. Under the action of the first spring 21, the first connecting tube 12 and the first chassis 27 will move downward, driving the first stopper 34 downward. When the first stopper 34 descends, it will contact the step surface 331 corresponding to the arc-shaped anti-drop portion 33. Due to the different heights of the step surfaces 331 on the arc-shaped anti-drop portion 33, the first stopper 34 will stop descending after contacting the corresponding step surface 331, thereby driving the treatment needle 7 to descend to the corresponding depth, thereby meeting the needs of different acupuncture depths. The reset tube can be reset by the reset rod.

[0043] like Figure 9 As shown, for example, the placebo needle set 2 has the same appearance as the treatment needle set 1 , and includes a second needle tube 35 , a second drop assembly 36 , a second depth adjustment assembly 37 , a second resistance drop assembly 38 and a placebo needle 39 .

[0044] Among them, the second depth adjustment component 37, the second drop component 36 and the placebo needle 39 are arranged in the second needle tube 35 from top to bottom in sequence, and the second drop resistance component 38 is arranged in the second needle tube 35 and is located below the second drop component 36.

[0045] The second depth adjustment component 37 is connected to the second descending component 36, the placebo needle 39 is slidably connected to the second descending component 36, the second drop resistance component 38 is arranged in the second needle tube 35 and is located below the second descending component 36, the second drop resistance component 38 is configured to adjust the position of the second descending component 36 in the second needle tube 35, and the second descending component 36 is configured to control the descending distance of the placebo needle 39 to a set value when moving downward in the second needle tube 35. Generally, the downward moving distance of the placebo needle 39 is 1-3 mm, that is, only a pinhole is left on the patient's skin.

[0046] For example, the second needle tube 35 has the same structure as the first needle tube 3 , and the second resistance drop component 38 has the same structure as the first resistance drop component 6 , and their details will not be repeated.

[0047] like Figure 10 As shown, for example, the second landing assembly 36 includes a second reset tube 40, a second connecting tube 41, an inner spring sleeve 42, a first acupuncture fixing rod 43 and a second spring 44, wherein the second reset tube 40 has the same structure as the first reset tube 11, and the second connecting tube 41 has the same structure as the first connecting tube 12, which will not be repeated.

[0048] For example, the second depth adjustment assembly 37 includes a second color recognition part and a third spring 46. The second color recognition part is arranged at the top opening of the second needle tube 35. The second color recognition part includes a second color recognition body 45 and a second spring sleeve 47. The second color recognition body 45 is cylindrical. The bottom of the second color recognition body 45 is rotatably connected to the top opening of the second needle tube 35. The top of the second color recognition body 45 is located outside the second needle tube 35, so the user can rotate the second color recognition body 45.

[0049] A plurality of color zones are circumferentially arranged at the same height as the color recognition port 19 of the second needle tube 35 on the outer side surface of the second color recognition body 45. The colors of the plurality of color zones are different, and the plurality of color zones are the same size as the color recognition port 19 on the second needle tube 35. Each color zone forms a small block-shaped protrusion structure. The plurality of color zones horizontally surround the second color recognition body 45. Rotating the second color recognition body 45 can make each color zone fall exactly into the color recognition port 19 of the second needle tube 35.

[0050] A first circular hole 48 and a second circular hole 49 are provided in the middle of the second color recognition body 45 in sequence from top to bottom along the axial direction. The inner diameter of the second circular hole 49 is larger than that of the first circular hole 48 .

[0051] The top of the second spring sleeve 47 is interference-fitted with the second circular hole 49 , and a disc-shaped second chassis 50 is fixedly provided below the limiting ring 13 at the bottom of the second connecting tube 41 .

[0052] The bottom of the second color recognition body 45 is transmission-connected to the top of the second connecting tube 41. For example, the second depth adjustment assembly 37 also includes a second internal gear 51, and the second landing assembly 36 also includes a second external gear 52. The second internal gear 51 is sleeved on the outside of the second spring sleeve 47 and is located at the bottom of the second color recognition body 45. A second external gear 52 meshing with the second internal gear 51 is provided at the top of the second connecting tube 41.

[0053] The bottom of the second spring sleeve 47 is located in the second connecting tube 41 . The second spring 44 is disposed in the second spring sleeve 47 . The top of the second spring 44 contacts the top of the second circular hole 49 . The bottom of the second spring 44 contacts the second chassis 50 .

[0054] The inner spring sleeve 42 is arranged inside the second spring sleeve 47, the top of the inner spring sleeve 42 is fixedly connected to the top of the second circular hole 49, the second spring 44 is sleeved on the outside of the inner spring sleeve 42, the first acupuncture fixing rod 43 is located in the inner spring sleeve 42, the top of the first acupuncture fixing rod 43 is slidably connected to the first circular hole 48, and the bottom of the first acupuncture fixing rod 43 passes through the second chassis 50 and is fixedly connected to the placebo needle 39.

[0055] The first acupuncture fixing rod 43 is provided with a first stop ring 53 and a second stop ring 54. The first stop ring 53 is located in the inner spring sleeve 42, and the second stop ring 54 is located below the inner spring sleeve 42. A first inner flange 55 is provided at the bottom of the inner spring sleeve 42. The first inner flange 55 is located between the first stop ring 53 and the second stop ring 54. A second groove 56 matching the second stop ring 54 is provided at the connection between the second chassis 50 and the second connecting tube 41. The third spring 46 is sleeved on the first acupuncture fixing rod 43. The top of the third spring 46 contacts the top of the second circular hole 49, and the bottom of the third spring 46 contacts the first stop ring 53.

[0056] When not in use, the second chassis 50 pushes the second stop ring 54 upward, compressing the third spring 46. When the second chassis 50 descends, the third spring 46 is released, pushing the first stop ring 53 downward. The first acupuncture rod 43 slides within the first circular hole 48. The first stop ring 53 stops descending when it contacts the first inner flange 55 of the inner spring sleeve 42. Therefore, regardless of the rotation of the color zones of the second color recognition body 45, the placebo needle 39 on the first acupuncture rod 43 moves the same distance.

[0057] like Figure 12 As shown, for example, the first depth adjustment assembly 5 includes a first plunger 57 and a fourth spring 58. The first plunger 57 is "T"-shaped. The first plunger 57 includes a third cylindrical portion 59 and a fourth cylindrical portion 60 connected from top to bottom. The outer diameter of the third cylindrical portion 59 is greater than the outer diameter of the fourth cylindrical portion 60. The third cylindrical portion 59 is rotatably connected to the top opening of the first needle tube 3. The fourth cylindrical portion 60 is located inside the first needle tube 3. There is a second cavity between the fourth cylindrical portion 60 and the first needle tube 3. The fourth spring 58 is located in the second cavity and is sleeved on the fourth cylindrical portion 60.

[0058] like Figure 12 As shown, for example, the first dropper assembly 4 includes a first dropper tube 61, which is sleeved on the outside of the fourth spring 58 and located between the first needle tube 3 and the fourth spring 58. A second stopper 62 is provided at the bottom of the first dropper tube 61, and the bottom of the second stopper 62 is fixedly connected to the treatment needle 7.

[0059] A second buckle 63 matching the bayonet 8 of the first needle tube 3 is provided on the outer side surface of the first drop tube 61 . The second buckle 63 has the same structure as the first buckle 15 .

[0060] For example, the first descending assembly 4 also includes a second reset rod 64, which passes through the reset groove 17, one end of the second reset rod 64 is fixedly connected to the second stop block 62 at the bottom of the first descending tube 61, and the other end of the second reset rod 64 is located outside the first needle tube 3. The other end of the second reset rod 64 is provided with a spherical handle for easy operation.

[0061] like Figure 11 and Figure 12 As shown, for example, the first resistance-drop assembly 6 includes a plurality of resistance-drop buttons 65 vertically distributed on the first needle tube 3 .

[0062] like Figure 13 As shown, the anti-drop button 65 includes a press plate 66, a movable rod 67, two clamping blocks 68, a locking block 69 and a blocking rod 70. The tube wall of the first needle tube 3 is provided with a third circular hole 71 and a fourth circular hole 72 that are interconnected from the outside to the inside at the position of each anti-drop button 65, and the inner diameter of the fourth circular hole 72 is larger than the inner diameter of the third circular hole 71.

[0063] The two clamping blocks 68 are relatively arranged in the fourth circular hole 72 , and one end of the two clamping blocks 68 close to the third circular hole 71 is fixedly connected to the side wall of the fourth circular hole 72 , and a third cavity is defined between the two clamping blocks 68 .

[0064] The press disk 66 is arranged on the outside of the first needle tube 3, the hemispherical locking block 69 is arranged in the third cavity, one end of the movable rod 67 is fixedly connected to the press disk 66, and the other end of the movable rod 67 passes through the third circular hole 71 and is fixedly connected to the hemispherical locking block 69. The movable rod 67 is slidingly connected to the third circular hole 71, and the baffle rod 70 is arranged in the fourth circular hole 72 and is located at one end of the two clamping blocks 68 away from the third circular hole 71. The locking block 69 is fixedly connected to the baffle rod 70.

[0065] For example, the third cavity includes a cylindrical segment 73 and an arc segment 74 that are interconnected from the outside to the inside. The arc surface of the arc segment 74 is tangent to the arc surface of the locking block 69 to form a clamp for the locking block 69, thereby fixing the position of the movable rod 67 and the blocking rod 70.

[0066] By pressing the button 66, the locking block 69 can be pressed into the arc section 74 to form a clamp. When in use, the second buckle 63 can be disengaged from the bayonet 8 by pressing the elastic top pressure part 9. The first descending tube 61 drives the treatment needle 7 to descend under the action of the fourth spring 58, and the second stop block 62 stops descending when it descends to contact the stop rod 70 of the set anti-descent button 65.

[0067] like Figure 14 As shown, for example, the second depth adjustment assembly 37 includes a second plunger 75 and a fifth spring 76. The second plunger 75 is "T"-shaped. The second plunger 75 includes a fifth cylindrical portion and a sixth cylindrical portion connected in sequence from top to bottom. The outer diameter of the fifth cylindrical portion is greater than the outer diameter of the sixth cylindrical portion. The fifth cylindrical portion is rotatably connected to the top opening of the second needle tube 35. The sixth cylindrical portion is located inside the second needle tube 35. There is a fourth cavity between the sixth cylindrical portion and the second needle tube 35. The fifth spring 76 is located in the fourth cavity and is sleeved on the sixth cylindrical portion.

[0068] The second drop assembly 36 includes a second drop tube 77 , a second acupuncture fixing rod 78 and a sixth spring 79 . The second drop tube 77 has the same structure as the first drop tube 61 and will not be described in detail.

[0069] The second drop tube 77 is sleeved on the outside of the fifth spring 76 and is located between the second needle tube 35 and the fifth spring 76 . A third stopper 80 is provided at the bottom of the second drop tube 77 .

[0070] A fifth cavity is axially provided inside the second plunger 75 , and the second acupuncture fixing rod 78 is located in the fifth cavity. The bottom of the second acupuncture fixing rod 78 passes through the third stopper 80 and is fixedly connected to the placebo needle 39 .

[0071] The second acupuncture fixing rod 78 is provided with a third stop ring 81 and a fourth stop ring 82. The bottom of the second plunger 75 is provided with a second inner flange 83, which is located between the third stop ring 81 and the fourth stop ring 82. The third stop ring 81 is located in the fifth cavity, and the fourth stop ring 82 is located below the fifth cavity. The sixth spring 79 is sleeved on the second acupuncture fixing rod 78, with the top of the sixth spring 79 contacting the top of the fifth cavity and the bottom of the sixth spring 79 contacting the third stop ring 81. When this solution is used, the placebo needle 39 does not descend as the drop tube descends.

[0072] In the above embodiment, no matter what acupuncture depth is set during use, the placebo needle set 2 can only puncture the skin by 1-3 mm.

[0073] In a double-blind clinical study of acupuncture, treatment needle set 1 and placebo needle set 2 were randomly assigned to different patients. Furthermore, patients were unaware of the specific set type they were assigned. This random assignment and unawareness further ensured the effectiveness of the double-blind design. Placebo needle set 2 and treatment needle set 1 were identical in design, making it impossible for users to discern the needle type based solely on appearance. The operation procedures for both sets were also identical, making it impossible for patients to distinguish between genuine and fake sets simply by manipulation. Furthermore, the patient's sense of touch was identical; the needles of both treatment needle set 1 and placebo needle set 2 would contact the user.

[0074] For example, a fixing plate 84 is provided below the bottom of the first needle tube 3 and the second needle tube 35, and a detachable adhesive tape 88 is provided at the bottom of the fixing plate 84. The adhesive tape 88 fixes the set to the skin to prevent the set from falling or shifting during the acupuncture process.

[0075] For example, the fixing plate 84 is provided with a first through hole at the location of the adhesive tape 88. A blood-simulating piece 85 is disposed within the first through hole. The blood-simulating piece 85 comprises a cotton ball dipped in iodine and covered with a plastic film. During use, both the treatment needle 7 and the placebo needle 39 pierce the cotton ball, thereby disinfecting the skin after the acupuncture. Furthermore, the color of the iodine can mask any differences in bleeding volume between the treatment and placebo groups.

[0076] For example, sterile red dry cotton balls are provided on the inner sides of the bottoms of the first needle tube 3 and the second needle tube 35. The dry cotton balls are used to absorb blood stains. Since the amount of bleeding during acupuncture is generally not too large, and sometimes there is no bleeding, even if there is a small amount of bleeding, the red dry cotton balls can cover up the traces of bleeding.

[0077] For example, the bottom openings of the first needle tube 3 and the second needle tube 35 are both provided with an acupuncture guide block 86, the arc-shaped anti-drop portion 33 of the first anti-drop component 6 is arranged around the outside of the acupuncture guide block 86 in the first needle tube 3, and the arc-shaped anti-drop portion 33 of the second anti-drop component 38 is arranged around the outside of the acupuncture guide block 86 in the second needle tube 35; the acupuncture guide block 86 in the first needle tube 3 is provided with a second through hole matching the diameter of the treatment needle 7, and the acupuncture guide block 86 in the second needle tube 35 is provided with a second through hole matching the diameter of the placebo needle 39, so that the treatment needle 7 and the placebo needle 39 can smoothly pass through the acupuncture guide block 86.

[0078] The outer wall of the acupuncture guide block 86 in the first needle tube 3 is fixedly connected to the inner wall of the arc-shaped resistance drop portion 33 of the first resistance drop assembly 6, and the height of the acupuncture guide block 86 in the first needle tube 3 is lower than the height of the lowest step surface 331 of the arc-shaped resistance drop portion 33 of the first resistance drop assembly 6.

[0079] Acupuncture guide block 86 is used to enhance acupuncture stability. During acupuncture, due to the softness and elasticity of human skin, the needle may occasionally experience slight movement or deflection. The presence of acupuncture guide block 86 provides a fixed path, allowing the needle to smoothly pass through the skin along a predetermined path, minimizing the possibility of deflection and shaking (similar to the clamping needle insertion method, which prevents unexpected situations such as needle bending and folding).

[0080] For example, both the treatment needle set 1 and the placebo needle set 2 include an electric needle connector 87. The electric needle connector 87 is L-shaped. One end of the electric needle connector 87 of the treatment needle set 1 is located outside the first needle tube 3, and the other end passes through the first needle tube 3 and is fixedly connected to the bottom of the first landing assembly 4. For example, the other end of the electric needle connector 87 of the treatment needle set 1 passes through the first needle tube 3 and is fixedly connected to the bottom of the second stopper 62.

[0081] One end of the electroacupuncture connector 87 of the placebo needle set 2 is located outside the second needle tube 35, and the other end passes through the second needle tube 35 and is fixedly connected to the bottom of the second landing assembly 36. For example, the other end of the electroacupuncture connector 87 of the placebo needle set 2 passes through the second needle tube 35 and is fixedly connected to the bottom of the third stopper 80.

[0082] The electroacupuncture connector 87 is made of metal material, and the second stopper 62 and the third stopper 80 are both made of metal material. This is because in some cases, the treatment needle 7 needs to be connected to electricity to perform electroacupuncture treatment on the patient.

[0083] In summary, the present invention effectively overcomes the shortcomings of the prior art and has high industrial application value.

[0084] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
