Abstract
Description
Technical Field
[0001] This utility model relates to the field of acupuncture needle technology, specifically to an acupuncture needle that is easy to hold and rotate. Background Technology
[0002] Acupuncture needles are the main tools used in traditional Chinese medicine acupuncture therapy. They regulate the flow of qi and blood and promote the body's self-repair ability by stimulating specific acupoints, thereby achieving the purpose of treating diseases and maintaining health. Acupuncture needles usually consist of the following parts: needle tip, needle body, and needle handle.
[0003] Most existing acupuncture needle handles are made of metal or plastic, which has some limitations in practical applications, as follows:
[0004] First, the smooth surface of traditional metal or plastic needle handles lacks sufficient friction, requiring doctors to exert greater grip strength to maintain stability during operation. Prolonged use can lead to hand fatigue, affecting accuracy and efficiency.
[0005] Secondly, when performing more complex acupuncture techniques, such as twisting and lifting, the contact area between the doctor's fingers and the needle handle is limited. Combined with the effects of sweat or disinfectant, this easily causes the needle handle to slip from the hand. This slippage not only increases the difficulty of the procedure but can also lead to accidental injury, such as accidentally injuring the patient's skin or causing unnecessary pain.
[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content
[0007] This invention provides an acupuncture needle that is easy to hold and rotate, aiming to solve the technical problems mentioned in the background art.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is: an acupuncture needle that is easy to hold and rotate, comprising a needle handle and a needle body arranged sequentially from top to bottom;
[0009] The needle handle is coaxially provided with a positioning groove along the vertical direction for positioning the upper end of the needle body, and the opening of the positioning groove faces downward.
[0010] The needle handle and the needle body are coaxially assembled through the positioning groove, and the lower end of the needle body is the needle tip.
[0011] The outer circumferential surface of the needle handle is provided with anti-slip texture;
[0012] The needle handle has a twisting part; viewed from a cross-sectional angle, the width of the twisting part is greater than the width of the needle body;
[0013] The needle handle is provided with a concave gripping surface on its periphery, and the concave depth of the gripping surface is deeper in the middle and shallower at both ends.
[0014] The grip surface is provided with a damping structure.
[0015] The relevant content in the above plan is explained as follows:
[0016] In the above scheme, the needle body and needle handle are set along the vertical direction because when inserting the needle into the patient's body, the needle handle is usually held and the needle body is inserted into the patient's body. This is the current common usage method. Therefore, the setting method of the needle body and needle handle will also refer to this usage method.
[0017] In the above scheme, the needle body is fixedly set in the positioning groove of the needle handle, that is, the needle handle can be formed on the periphery of the needle body by injection molding; the positioning groove of the needle handle and the needle body are interference fit; the positioning groove of the needle handle and the needle body are fixed by adhesive.
[0018] In the above solution, the anti-slip texture mainly serves to increase friction, so that the operator has sufficient grip strength and grip area when operating.
[0019] In the above scheme, the needle handle can be made of silicone material.
[0020] In the above solution, the presence of the twisting part can increase the user's grip area. At the same time, the larger size of the twisting part can prevent the operator from slipping off the grip.
[0021] In a further technical solution, the damping structure consists of several friction strips arranged at intervals along the vertical direction;
[0022] Furthermore, the extension direction of each friction strip towards the side away from the gripping surface is perpendicular to the plane containing the axis of the needle handle.
[0023] The above design allows the operator to further increase friction through the presence of the grip surface. At the same time, the concave depth, which is deeper in the middle and shallower at both ends, can concentrate the operator's grip area in the center of the needle handle, preventing the phenomenon of affecting the application of force to the needle body due to gripping too high or too low.
[0024] Furthermore, when the operator's fingers move relative to the needle handle along the axis of the needle handle, the above design increases friction and reduces the amount of movement.
[0025] In a further technical solution, the twisting part is located at the upper end of the needle handle and is wider in the middle and narrower at both ends in the vertical direction.
[0026] The following embodiments are provided for the twisting part. In the first embodiment, the twisting part is pot-shaped.
[0027] The design allows the operator to grip a wider area in the middle, where the fingers make greater contact with the twisting part, but the twisting area is small, making it suitable for shallower penetrations.
[0028] In a further technical solution, the twisting part is located at the upper end of the needle handle and is narrow in the middle and wide at both ends in the vertical direction.
[0029] In a further technical solution, the twisting part includes an upper limit part, a contraction part, and a lower limit part arranged sequentially from top to bottom, and all three are coaxially arranged with the needle handle;
[0030] The outer periphery of the contraction section is configured as a twisting area for the user's fingers.
[0031] The second type has a twisting section that is wide at both ends and narrow in the middle (such as...). Figure 5 and Figure 6 Specifically, it can be hourglass-shaped (e.g.) Figure 5 ).
[0032] However, the length of the contraction section may be shorter or longer than the lower and upper limit sections, depending on the specific requirements.
[0033] When this structure is assembled, the outer periphery of the contraction section is the user's finger twisting area. That is, the user's finger is limited by the lower limit section and the upper limit section, so that the user's finger will not easily slip off the twisting section when twisting.
[0034] That is, it has a large twisting area, which is suitable for penetrating deeper areas.
[0035] In a further technical solution, the twisting part further includes a spiral part, which is spirally arranged at least on the outer peripheral surface of the contraction part.
[0036] The spiral part can be provided only on the side wall of the contraction part or simultaneously on two or three outer peripheral surfaces of the lower limit part, the contraction part, and the upper limit part.
[0037] Since the user needs to pinch the twisting part and perform the twisting operation, the spiral part is used to control the number of twists so that the range and number of rotations are not easily affected.
[0038] In a further technical solution, the spiral part is a protrusion with a circular cross-section or a groove with a semi-circular cross-section.
[0039] When the spiral part is a groove with a semi-circular cross-section, a raised edge is provided at the edge of the groove opening to further increase the control over the rotation range and number of rotations. The groove opening is oriented away from the axis of the needle shank.
[0040] When the spiral part is a protrusion with a circular cross-section, the protrusion is glued to the lower limit part, the contraction part, and the upper limit part, or fixed by other means.
[0041] In comparison, when the spiral part is a groove with a semi-circular cross-section, it occupies less space, but the number of spiral turns in the groove is less, making it suitable for areas with a large twist amplitude; when the spiral part is a protrusion with a circular cross-section, it occupies more space, but the number of spiral turns in the protrusion is more, making it suitable for areas with a small twist amplitude.
[0042] In a further technical solution, the twisting part is a spherical structure disposed at the upper end of the needle handle, and the outer peripheral surface of the spherical structure is provided with multiple extension rings;
[0043] All of the aforementioned extension rings are coaxial from top to bottom and evenly spaced along the axis of the needle handle;
[0044] Viewed from a cross-sectional perspective, the tangent on the outer circumferential surface of the extended ring coincides with the tangent on the outer circumferential surface of the spherical structure.
[0045] In a further technical solution, all the extended rings are combined to form a cylindrical structure, the height of which is greater than the diameter of the spherical structure.
[0046] In the two embodiments described above, the needle insertion depth in Embodiment 1 is shallow, and the needle handle length in Embodiment 2 is relatively large. In order to increase the insertion depth based on Embodiment 1 without affecting the needle handle length, Embodiment 3 was designed.
[0047] The third type has a twisted part consisting of a spherical structure and an extension ring.
[0048] In this embodiment, when the fingers are normally pinching the middle area (i.e. the thickest area) of the spherical structure, and then when twisting, whether twisting upwards or downwards, due to the presence of the extension ring, even if the fingers and the needle handle move relative to each other in the axial direction, there will be no slippage.

[0065] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0066] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.
[0067] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.
[0068] See appendix Figures 1-7 As shown, an acupuncture needle that is easy to hold and rotate includes a needle handle 2 and a needle body 1 arranged sequentially from top to bottom;
[0069] A positioning groove 3 for positioning the upper end of the needle body 1 is coaxially arranged in the needle handle 2 along the vertical direction, and the opening of the positioning groove 3 faces downward.
[0070] The needle handle 2 and the needle body 1 are coaxially assembled through the positioning groove 3, and the lower end of the needle body 1 is the needle tip.
[0071] The outer circumferential surface of the needle handle 2 is provided with anti-slip texture 4;
[0072] The needle handle 2 has a twisting part 5; viewed from a cross-sectional perspective, the width of the twisting part 5 is greater than the width of the needle body 1.
[0073] The needle handle 2 has a concave gripping surface 6 on its periphery, and the concave depth of the gripping surface 6 is deeper in the middle and shallower at both ends.
[0074] The grip surface 6 is equipped with a damping structure.
[0075] In this invention, the needle body 1 and the needle handle 2 are arranged along the vertical direction because when inserting the needle into the patient's body, the needle handle 2 is usually held while the needle body 1 is inserted into the patient's body. This is the common usage method at present. Therefore, the arrangement of the needle body 1 and the needle handle 2 will also refer to this usage method.
[0076] In this utility model, the needle body 1 is fixedly disposed in the positioning groove 3 of the needle handle 2, that is, the needle handle 2 can be formed on the periphery of the needle body 1 by injection molding; the positioning groove 3 of the needle handle 2 and the needle body 1 are interference fit; the positioning groove 3 of the needle handle 2 and the needle body 1 are fixed by adhesive.
[0077] In this invention, the presence of anti-slip texture 4 mainly serves to increase friction, so that the operator has sufficient gripping force and gripping area when operating.
[0078] In this invention, the presence of the twisting part 5 can increase the user's grip area. At the same time, the larger size of the twisting part 5 can prevent the operator from slipping off the grip.
[0079] The anti-slip texture 4 is composed of intersecting lines.
[0080] In some specific embodiments, the damping structure consists of several friction strips 7 arranged at intervals along the vertical direction;
[0081] Furthermore, the extension direction of each friction strip 7 towards the side away from the gripping surface 6 is perpendicular to the plane containing the axis of the needle handle 2.
[0082] With the above design, the operator can further increase the friction through the presence of the grip surface 6. At the same time, the concave depth, which is deep in the middle and shallow at both ends, can concentrate the operator's grip area in the center of the needle handle 2, preventing the phenomenon that the force applied to the needle body 1 is affected by gripping too high or too low.
[0083] At the same time, when the operator's fingers and the needle handle 2 move relative to each other along the axis of the needle handle 2, the above design can also increase the friction and reduce the amount of movement.
[0084] In some specific embodiments, the twisting part 5 is located at the upper end of the needle handle 2, and is wide in the middle and narrow at both ends in the vertical direction.
[0085] like Figures 1-4 The following embodiments are provided for the twisting part 5. In the first embodiment, the twisting part 5 has a structure that is wide in the middle and narrow at both ends, such as a pot shape.
[0086] With the above design, the operator's grip area is the middle wide part. In this part, the amount of contact between the fingers and the twisting part 5 is large, but the twisting area is small, which is suitable for shallow penetration.
[0087] In some specific embodiments, the twisting part 5 is disposed at the upper end of the needle handle 2, and is narrow in the middle and wide at both ends in the vertical direction.
[0088] In some specific embodiments, the twisting part 5 includes an upper limit part 10, a contraction part 9 and a lower limit part 8 arranged sequentially from top to bottom, and all three are coaxially arranged with the needle handle 2;
[0089] The outer periphery of the contraction section 9 is configured as a twisting area for the user's fingers.
[0090] In the second embodiment, the twisting part 5 has a structure that is wide at both ends and narrow in the middle (e.g., ...). Figure 5 and Figure 6 Specifically, it can be hourglass-shaped (e.g.) Figure 5 ).
[0091] However, the length of the contraction section 9 may be shorter than that of the lower limit section 8 and the upper limit section 10. Figure 5 That's how it is in the middle), and it may also be longer than the lower limit part 8 and the upper limit part 10 ( Figure 6 That's how it is in China (the specific settings depend on your needs).
[0092] When this structure is assembled, the outer periphery of the contraction part 9 is the user's finger twisting area. That is, the user's finger is limited by the lower limit part 8 and the upper limit part 10, so that the user's finger will not easily slip off the twisting part 5 when twisting.
[0093] In this embodiment, the twisting area is large, making it suitable for penetrating deeper areas.
[0094] In some specific embodiments, the twisting part 5 further includes a spiral part 11, which is spirally disposed at least on the outer peripheral surface of the contraction part 9.
[0095] The spiral part 11 may be provided only on the side wall of the contraction part 9 or simultaneously on two or three outer peripheral surfaces of the lower limit part 8, the contraction part 9 and the upper limit part 10.
[0096] Since the user needs to pinch the twisting part 5 and perform the twisting operation, the spiral part 11 is used for control to ensure that the number of twists is controllable, so that the range and number of rotations are not easily affected. That is, during twisting, the spiral part 11 plays the role of guiding the twisting.
[0097] In some specific embodiments, the spiral portion 11 is a protrusion with a circular cross-section or a groove with a semi-circular cross-section.
[0098] When the spiral part 11 is a groove with a semi-circular cross-section, a raised edge 14 is provided at the edge of the groove opening to further increase the control over the rotation range and number of rotations. The groove opening is oriented away from the axis of the needle holder 2.
[0099] When the spiral part 11 is a protrusion with a circular cross-section, the protrusion is glued to the lower limit part 8, the contraction part 9 and the upper limit part 10, or fixed by other means.
[0100] In comparison, when the spiral part 11 is a groove with a semi-circular cross-section, it occupies less space, but the number of spiral turns in the groove is less, making it suitable for areas with a large twist amplitude; when the spiral part 11 is a protrusion with a circular cross-section, it occupies more space, but the number of spiral turns in the protrusion is more, making it suitable for areas with a small twist amplitude.
[0101] In some specific embodiments, the twisting part 5 is a spherical structure 12 disposed at the upper end of the needle handle 2, and the outer peripheral surface of the spherical structure 12 is provided with multiple extension rings;
[0102] All extension loops are coaxial from top to bottom and evenly spaced along the axis of needle shank 2;
[0103] Viewed from a cross-sectional perspective, the tangent on the outer circumference of the extension ring coincides with the tangent on the outer circumference of the spherical structure 12.
[0104] In some specific embodiments, all the extended rings are combined to form a cylindrical structure, the height of which is greater than the diameter of the spherical structure 12.
[0105] In the two embodiments described above, the needle body 1 in Embodiment 1 has a shallow insertion depth, and the needle handle 2 in Embodiment 2 has a larger length. In order to increase the insertion depth based on Embodiment 1 without affecting the length of the needle handle 2, Embodiment 3 was designed.
[0106] In the third embodiment, the twisting part 5 is a structure in which a spherical structure 12 and an extension ring 13 are combined.
[0107] In this embodiment, when the fingers pinch the middle area (i.e. the thickest area) of the spherical structure 12, and then when twisting, whether twisting upwards or downwards, due to the presence of the extension ring 13, even if the fingers and the needle handle 2 move relative to each other in the axial direction, there will be no slippage.
[0108] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
