Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of medical devices, specifically to unsheathed floating needles. Background Technology

[0002] Floating needle therapy is a modern acupuncture technique that focuses on relieving muscle tension through sweeping techniques in the superficial fascia layer, thereby treating muscle-related pain. Traditional floating needles consist of a needle core, a soft cannula, and a protective sleeve. The needle core is embedded in the soft cannula, and the soft sleeve reduces the possibility of needle breakage. When inserting the needle, both the needle core and the soft cannula need to be inserted into the superficial fascia layer.

[0003] However, when using the above method for needle insertion, the needle core and soft cannula need to be inserted into the patient's subcutaneous superficial fascia layer together. The diameter of the soft cannula is relatively large, which often presents technical problems such as strong stinging sensation and high possibility of bleeding for the patient.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background of the inventive concept, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The summary portion of this disclosure is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description portion. This summary portion is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] Some embodiments of this disclosure provide a sleeveless floating needle to address one or more of the technical problems mentioned in the background section above.

[0007] Some embodiments of this disclosure provide a sleeveless floating needle device, which includes: a needle handle and a needle body, wherein the front end of the needle body is provided with a needle tip; the needle tip has a puncture structure; a stepped structure is provided between the needle body and the needle handle; the stepped structure includes a first step and a second step; the cross-sectional area of ​​the first step gradually decreases from the needle handle towards the needle body; the first step and the second step are fixedly connected; the second step is offset to one side of the first step; the first step is connected to the needle handle; the needle handle is a square prism, and one side of the square prism is provided with an anti-slip structure; the side of the square prism with the anti-slip structure is opposite to the offset of the second step; the second step is provided with a needle hole; the needle hole is funnel-shaped; the rear end of the needle body is embedded in the needle hole.

[0008] Optionally, the sides of the first step are chamfered.

[0009] Optionally, the connection area between the first step and the second step is chamfered.

[0010] Optionally, the puncture structure of the needle tip of the aforementioned needle body includes a conical blunt tip.

[0011] Optionally, the needle body is configured to produce elastic deformation.

[0012] Optionally, the needle handle described above has a hollow structure.

[0013] Optionally, the two ends of the needle handle are provided with recesses towards the middle; the recesses have arc-shaped transition surfaces.

[0014] Optionally, the above-mentioned anti-slip structure includes at least one of the following: raised dots, grooves, and corrugations.

[0015] The various embodiments of this disclosure have the following beneficial effects: Some embodiments of this disclosure provide a sheathless floating needle. This sheathless floating needle reduces the possibility of needle breakage during sweeping by using a funnel-shaped needle hole. During insertion, only the needle body is used, without the soft sheath, which greatly reduces the patient's stinging sensation and the possibility of bleeding. Specifically, the reason for large amounts of bleeding and strong stinging sensation in patients is that traditional floating needles require inserting both the needle core and the soft sheath into the patient's subcutaneous superficial fascia layer during insertion. While the soft sheath can reduce the possibility of needle core breakage, its large diameter often results in strong stinging sensation and a high possibility of bleeding for the patient. Based on this, some embodiments of this disclosure provide a sheathless floating needle, which includes a needle handle and a needle body. The aforementioned needle body has a needle tip at its front end; the needle tip has a puncture structure; a stepped structure is provided between the needle body and the needle handle; the stepped structure includes a first step and a second step; the cross-sectional area of ​​the first step gradually decreases from the needle handle towards the needle body; the first step and the second step are fixedly connected; the second step is offset to one side of the first step; the first step is connected to the needle handle; the needle handle is a square prism, and an anti-slip structure is provided on one side of the square prism; the side of the square prism with the anti-slip structure is opposite to the offset of the second step; the second step has a needle hole; the needle hole is funnel-shaped; the rear end of the needle body is embedded in the needle hole. This embodiment reduces the possibility of needle breakage during sweeping by using the funnel-shaped needle hole, and during insertion, only the needle body is used, without the use of a soft cannula, which can greatly reduce the patient's pain and the possibility of bleeding.

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Figure 1 This is a schematic diagram of the structure of a sleeveless floating needle according to some embodiments of the present disclosure. Figure 1 It includes needle handle 1, first step 2, second step 3, needle body 4, needle tip 5, and anti-slip structure 6.

[0028] Figure 2 This is a cross-sectional view of a sleeveless floating needle according to some embodiments of this disclosure. Figure 2 Including hollow structure 7.

[0029] In some embodiments, the aforementioned unsheathed floating needle includes a needle handle 1 and a needle body 4. The needle body 4 can be a steel needle. For example, the needle body 4 can be a solid steel needle with a diameter ranging from 0.3 mm to 0.7 mm to ensure that the needle body 4 is not easily broken and to transmit the operating force from the needle handle 1 to the needle tip 5. The needle tip 5 is located at the front end of the needle body 4. The needle tip 5 has a puncture structure. The puncture structure can be a pyramidal structure to reduce puncture resistance and pain. For example, the puncture structure can be a square pyramid. A rounded transition can be provided at the junction of each facet to prevent sharp edges from damaging the tissue during sweeping and to reduce the risk of bleeding. The needle handle 1 can be a square prism, and the edges of the square prism can be chamfered for easy gripping by the user during sweeping.

[0030] In some embodiments, a stepped structure is provided between the needle body 4 and the needle handle 1. This stepped structure reduces the concentrated stress at the connection between the needle body 4 and the needle handle 1, preventing breakage of the needle body 4 and the needle handle 1. The stepped structure includes a first step 2 and a second step 3. The first step 2 connects to the needle handle 1. The second step 3 connects the needle body 4 and the first step 2. The first step 2 can be a square prism with chamfered edges to prevent discomfort when touched or gripped by fingers. The cross-sectional area of ​​the first step 2 gradually decreases from the needle handle 1 towards the needle body 4, conforming to the fingers and reducing discomfort during operation. The first step 2 and the second step 3 are fixedly connected. The second step 3 can be a cylindrical structure, for example, a cylinder. The cross-sectional area of ​​the second step 3 is smaller than the cross-sectional area of ​​the connection surface with the first step 2, reducing obstruction of the user's view during needle insertion. The second step 3 can be offset to one side of the first step 2. For example, Figure 1In this design, the second step 3 can be offset at the edge of the first step 2, allowing the second step 3 to be closer to the skin during sweeping, thus bringing the needle body 4 closer to the superficial fascia layer. An anti-slip structure 6 is provided on one side of the square column. The anti-slip structure 6 can be evenly distributed protrusions. The side of the square column with the anti-slip structure 6 is offset from the second step 3. For example, the anti-slip structure 6 can be located on the side away from the second step 3 to increase visibility, making it easier for the user to identify the direction of the needle handle 1. The second step 3 has a needle hole. The inner side of the needle hole can be designed in a funnel shape to reduce concentrated stress during sweeping and prevent the needle body 4 from breaking. The rear end of the needle body 4 is embedded in the needle hole. The needle body 4 can be fixed by an interference fit between the needle hole and the needle body 4 to prevent it from falling off during use.

[0031] Optionally, the side of the first step 2 is chamfered to reduce the risk of the first step 2 causing skin scratches during sweeping.

[0032] Optionally, the connection area between the first step 2 and the second step 3 is chamfered to reduce stress concentration and prevent cracks from forming in the connection area, which could lead to breakage.

[0033] Optionally, the puncture structure of the needle tip 5 of the needle body 4 may include a conical blunt tip. The conical blunt tip 5 can reduce the pain when piercing the skin and reduce damage to the tissue and bleeding risk when sweeping.

[0034] Optionally, the needle body 4 is configured to undergo elastic deformation. For example, the needle body 4 can be a medical-grade stainless steel needle, such as 316L stainless steel. This type of material can ensure the strength of the needle body 4 while also having good elasticity, which can prevent the needle body 4 from breaking due to excessive rigidity during sweeping.

[0035] Optionally, the needle handle 1 can be a hollow structure 7, which can not only reduce the overall weight of the needle and prevent hand fatigue when the user sweeps, but also save costs.

[0036] Optionally, the needle handle 1 has recessed portions at both ends towards the center. The recessed portions have arc-shaped transition surfaces, which can make the needle handle 1 dumbbell-shaped as a whole, thereby improving the stability of the user holding the needle handle 1 when sweeping.

[0037] Optionally, the anti-slip structure 6 includes at least one of the following: raised dots, grooves, and ripples. For example, the ripples can be a wave-like or undulating continuous texture. The anti-slip structure 6 can increase the friction when the user grips the object, ensuring that the sweeping action is completed easily.

[0038] Furthermore, in the process of adopting technical solutions to solve the technical problems mentioned in the background art, the inventors discovered that traditional floating needles are disposable needles, which are costly, and the needle handle cannot be adjusted, making them inconvenient for users. In order to save costs while also making it convenient for users to use the needles, and considering the technology possessed by the inventors' company, the following solution was decided upon.

[0039] Figure 3 This is a schematic diagram of the needle body and the second step of the unsheathed floating needle according to some embodiments of this disclosure. Figure 3 Includes groove 8, guide groove 9, and mounting component 10.

[0040] Figure 4 This is a schematic diagram of the handle structure of a sleeveless floating needle device according to some embodiments of this disclosure. Figure 4 It includes a first connector 11, a mounting hole 12, a buckle 13, a guide ridge 14, and a first needle handle 17.

[0041] Figure 5 This is a schematic diagram of the structure of another needle handle of the sleeveless floating needle device according to some embodiments of this disclosure. Figure 5 It includes a second connector 15, a groove array 16, and a second needle handle 18.

[0042] Optionally, the first step 2 and the second step 3 are detachably connected, facilitating the replacement of the second step 3 and the connected needle body 4. Specifically, the first step 2 is provided with a mounting hole 12. The mounting hole 12 can be square, preventing the second step 3 from shaking during lateral sweeping after connection. The mounting hole 12 can be located on one side of the first step 2, allowing the second step 3 to be laterally inserted into the mounting hole 12, preventing the needle body 4 from falling off when the unsheathed floating needle is withdrawn. The mounting hole 12 is provided with a guide ridge 14. The shape of the guide ridge 14 includes, but is not limited to, square, arc, and serrated. The guide ridge 14 can be symmetrically distributed on both sides of the mounting hole 12. The mounting hole 12 is fitted with a buckle 13. For example, the buckle 13 can be a "U"-shaped buckle 13, closely attached to the inner wall of the mounting hole 12, and can be located on both sides of the guide ridge 14. The buckle 13 is provided with a protrusion. The buckle 13 can undergo elastic deformation. The inner wall of the mounting hole 12 has a cavity. The buckle 13 undergoes elastic deformation during installation of the second step 3, allowing the protrusion to enter the cavity, making installation of the second step 3 easier. The protrusion can be located at both ends of the buckle 13. One end of the second step 3 has a pinhole for fixing and nesting the needle body 4. The pinhole can be funnel-shaped, allowing the needle body 4 some deformation space during sweeping to prevent breakage. The other end of the second step 3 has a mounting member 10 corresponding to the mounting hole 12. The shape of the outer wall of the mounting member 10 matches the shape of the mounting hole 12. For example, the mounting hole 12 can be square, and the outer wall of the mounting member 10 can be square enough to fit into the mounting hole 12. The outer wall of the mounting member 10 has a guide groove 9. The guide grooves 9 can be symmetrically distributed on both sides of the outer wall of the mounting member 10, corresponding to the position of the guide ridge 14. The guide ridge 14 matches the guide groove 9. For example, the guide ridge 14 can be an arc-shaped structure, and the guide groove 9 can be an arc-shaped structure of the same size. When installing the second step 3, the guide groove 9 and the guide ridge 14 can be aligned first, and then pressed along the direction of the guide ridge 14. The outer wall of the mounting member 10 is provided with a groove 8. The protrusion is configured to fit into the groove 8. For example, the protrusion can be a hemispherical protrusion, and the groove 8 can be a matching hemispherical groove.In practice, when connecting the first step 2 and the second step 3, the two sides with the guide groove 9 can be used as the two sides of the second step 3. Then, the guide groove 9 and the guide ridge 14 are aligned, and then pressed along the direction of the guide ridge 14. At the same time, the buckle 13 is elastically deformed by the side of the mounting member 10, and the protrusion enters the cavity. When the mounting member 10 is fully inserted into the mounting hole 12, the protrusion is embedded in the groove 8, preventing the second step 3 from falling off. Simultaneously, the square structure design of the mounting hole 12 and the mounting member 10 prevents the second step 3 from shaking during the sweeping of the needle body 4. When disassembling the second step 3, the mounting member 10 can be pushed out of the mounting hole 12 by applying a force in the opposite direction to the needle hole, thus completing the disassembly of the second step 3. Replacing only the needle body 4 and the second step 3 can reduce costs.

[0043] Optionally, the needle handle 1 includes a first needle handle 17 and a second needle handle 18. Both the first needle handle 17 and the second needle handle 18 can be square prisms, making them less prone to rolling and easier for the user to grip. One end of the first needle handle 17 has the first step 2, which can connect the second step 3 and the needle handle 4. The end of the first needle handle 17 with the first step 2 is designated as the front end, and the other end as the rear end. The cross-sectional area of ​​the first needle handle 17 can gradually decrease from the front end with the first step 2 to the rear end, and the connecting surfaces at both ends of the first needle handle 17 can be arc-shaped surfaces. For example, the cross-sectional area of ​​the rear end of the first needle handle 17 is 2 / 3 of the cross-sectional area of ​​the front end, making it easier for the user to grip. The rear end of the first needle handle 17 has a first connecting member 11. The first connecting member 11 can be a spherical protrusion. The top of the spherical protrusion has a vertical hole. The vertical hole can be used to embed an elastic component. The elastic component can be a spring. The upper end of the vertical hole has a storage cavity. The aforementioned receiving cavity can hold a rolling element. The rolling element can be a steel ball. When the spring is not inserted into the vertical hole, the rolling element can be completely placed in the receiving cavity. When the spring is inserted into the vertical hole, and the rolling element is then placed, the rolling element will be lifted a certain distance by the spring, causing it to protrude slightly at the apex of the spherical protrusion, for example, 2mm. One end of the second needle handle 18 is provided with a second connecting member 15. The second connecting member 15 can be a spherical groove. The first needle handle 17 and the second needle handle 18 can be connected by a spherical fit. The second needle handle 18 can be adjusted in direction within a certain conical range using the structure of the spherical protrusion and the spherical groove. The end of the second needle handle 18 with the second connecting member 15 is designated as the front end, and the other end as the rear end. The rear end of the second needle handle 18 can be a hollow structure, which not only reduces the overall weight of the needle and prevents hand fatigue during sweeping, but also saves costs. The cross-sectional area of ​​the front end of the second needle handle 18 is the same as the cross-sectional area of ​​the rear end of the first needle handle 17, and the cross-sectional area of ​​the rear end of the second needle handle 18 is the same as the cross-sectional area of ​​the front end of the first needle handle 17. The connecting surfaces at both ends of the second needle handle 18 can be arc-shaped surfaces. When the first needle handle 17 and the second needle handle 18 are connected, they can form a dumbbell-shaped needle handle, making it easier for the user to grip. The spherical groove can be provided with a groove array 16, which can be uniformly distributed grooves. The groove array 16 is uniformly distributed on the inner wall of the spherical groove. The groove array 16 can be embedded in the rolling element to play a fixing role when adjusting the second handle.In practice, users can more easily complete the sweeping action by adjusting the angle of the second needle handle 18. At the same time, the rolling element is embedded in the groove array 16, which can fix the angle of the second needle handle 18, making it easier to apply force to the second needle handle 18 during sweeping.

[0044] The above-described optional embodiments, as an inventive point of this disclosure, solve the technical problem of "high cost and inconvenient use of floating needles". The specific factors contributing to the high cost and inconvenience of floating needles are as follows: the needle body and handle are usually molded as a single piece, and must be discarded together after use. The handle has a fixed shape and cannot be adjusted. Solving these factors can reduce costs and improve ease of use. To achieve this effect, this disclosure also provides a design with a replaceable needle body and an adjustable handle direction. After use, only the needle body is discarded, while the handle remains usable, reducing costs. Dividing the handle into two sections with a spherical protrusion and a spherical groove connecting structure allows for adjustment of the handle's direction, facilitating force application during sweeping. This reduces costs and makes the needle more convenient for users.

[0045] Some embodiments of this disclosure provide a sheathless floating needle device. This sheathless floating needle device reduces the possibility of needle breakage during sweeping by using a funnel-shaped needle hole. During insertion, only the needle body is used, without the soft sheath, which can greatly reduce the patient's pain and the possibility of bleeding. Specifically, the reason for large amounts of bleeding and intense pain in patients is that traditional floating needles require inserting both the needle core and the soft sheath into the superficial fascia layer of the patient's skin during insertion. While the soft sheath can reduce the possibility of needle core breakage, its large diameter leads to large amounts of bleeding and intense pain. Based on this, some embodiments of this disclosure provide a sheathless floating needle device, which includes a needle handle and a needle body. The aforementioned needle body has a needle tip at its front end; the needle tip has a puncture structure; a stepped structure is provided between the needle body and the needle handle; the stepped structure includes a first step and a second step; the cross-sectional area of ​​the first step gradually decreases from the needle handle towards the needle body; the first step and the second step are fixedly connected; the second step is offset to one side of the first step; the first step is connected to the needle handle; the needle handle is a square prism, and an anti-slip structure is provided on one side of the square prism; the side of the square prism with the anti-slip structure is opposite to the offset of the second step; the second step has a needle hole; the needle hole is funnel-shaped; the rear end of the needle body is embedded in the needle hole. This embodiment reduces the possibility of needle breakage during sweeping by using the funnel-shaped needle hole, and during insertion, only the needle body is used, without the use of a soft cannula, which can greatly reduce the patient's pain and the possibility of bleeding.

[0046] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
