Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a magnetic acupuncture device and a needle insertion method. Background Technology

[0002] Acupuncture is a general term for needling and moxibustion. Needling refers to inserting needles (usually filiform needles) into the patient's body at a certain angle under the guidance of traditional Chinese medicine theory, and using needling techniques such as twisting and lifting to stimulate specific parts of the body to achieve the purpose of treating diseases.

[0003] Conventional acupuncture methods mostly require manual operation, which carries the risk of needle contamination from human hands. Furthermore, the need to remove needles after each insertion is inconvenient and time-consuming for medical personnel. To address these issues, some new acupuncture devices have been developed. However, these devices generally suffer from two drawbacks: 1. Represented by acupuncture pens, these devices can only accommodate one type of needle at a time, and their overall length makes needle removal inconvenient; 2. Represented by cylindrical acupuncture devices, while capable of holding multiple needle types, they are often too bulky, difficult to operate, and their large size often obstructs vision during insertion, further complicating operation. Therefore, a magnetic acupuncture device is needed that combines the advantages of both types of devices while overcoming their disadvantages. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a magnetic acupuncture device and a method for inserting needles into the magnetic acupuncture device, in view of the above-mentioned defects of the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A magnetic acupuncture device is constructed, comprising a semi-circular acupuncture needle cylinder and an acupuncture needle activation part located at the axis of the acupuncture needle cylinder. The acupuncture needle cylinder has multiple acupuncture needle storage cavities distributed in an arc shape. The acupuncture needle cylinder and the acupuncture needle activation part are connected by multiple longitudinal needle outlet plates, each needle outlet plate having a transverse needle outlet channel. The acupuncture needle activation part includes a cylindrical body, with multiple needle outlet channels communicating with the cylindrical body. Each acupuncture needle storage cavity is connected to a corresponding needle outlet channel. The cylindrical body contains a magnetic rod that can pass through the needle outlet channels to attract acupuncture needles within the acupuncture needle storage cavity, and an activation groove connecting the multiple needle outlet channels. The upper end of the magnetic rod is provided with a traction column. The upper end of the cylinder, the upper ends of the plurality of needle plates, and the upper end of the acupuncture needle cylinder are all provided with sliding grooves for the traction column to slide, and adjacent sliding grooves are connected. The inner walls of the left and right sides of the activation groove are respectively provided with elastic holding rollers and threaded rollers. The front side of the activation groove is connected to the plurality of needle channels. The inner wall of the rear side of the activation groove is provided with a V-shaped positioning groove for positioning the magnetic rod. The lower end of the cylinder is provided with a needle outlet. The activation part of the acupuncture needle is provided with an adjustment unit for adjusting the position of the elastic holding roller and a drive unit for driving the threaded roller to rotate. The surface of the threaded roller is provided with drive threads.

[0007] The magnetic acupuncture device of the present invention has a lower end height of the cylinder body that is lower than the lower end height of the needle outlet plate. The drive unit includes a micro motor, a battery, and a control switch. The micro motor is inverted and disposed on the outer surface of the cylinder body. The threaded roller is connected to the movable end of the micro motor through a reduction gearbox. The cylinder body is provided with a slot for mounting the reduction gearbox.

[0008] The magnetic acupuncture device of the present invention comprises an adjustment unit and a drive unit located on the left and right sides of the cylinder, respectively; the adjustment unit includes a lever and a Y-shaped bracket connected to the cylinder in a damped rotational manner, and the two ends of the rotating shaft of the elastic pressure roller are respectively connected to the Y-shaped bracket by springs; one end of the lever is connected to the Y-shaped bracket, and the other end passes through the cylinder.

[0009] In the magnetic acupuncture device of the present invention, a guiding section is provided at the front side of the excitation groove where it connects with the plurality of needle outlet channels. The width of the guiding section is approximately equal to the outer diameter of the magnetic rod. The outer diameter of the magnetic rod is larger than the outer diameter of the tail end of the acupuncture needle, and the outer diameter of the magnetic rod is smaller than the width of the needle outlet channel.

[0010] The magnetic acupuncture device of the present invention includes an acupuncture needle baffle in the needle outlet channel. The acupuncture needle baffle is rotatably disposed on the inner wall of the needle outlet channel via a rotating shaft. A torsion spring is sleeved on the rotating shaft to reset the acupuncture needle baffle.

[0011] In the magnetic acupuncture device of the present invention, both the cylinder and the needle plate are made of transparent or semi-transparent materials.

[0012] In the magnetic acupuncture device of the present invention, a plurality of needle plates are radially distributed around the axis of the acupuncture needle cylinder.

[0013] A method for inserting needles into a magnetic acupuncture device, applied to the magnetic acupuncture device as described above, includes the following steps:

[0014] Push the traction column to move the magnetic rod out of the positioning slot of the activation slot and into the acupuncture needle storage cavity through the needle outlet channel corresponding to the acupuncture needle of the required needle type;

[0015] After the magnetic rod attracts the acupuncture needle in the acupuncture needle storage cavity, the traction column is pushed to reset the magnetic rod, and the position of the elastic holding roller is adjusted so that the elastic holding roller, the magnetic rod and the threaded roller form a triangle to clamp the acupuncture needle.

[0016] The drive unit rotates the threaded roller, and the friction provided by the threads on the roller to the acupuncture needle causes the acupuncture needle to move toward the needle outlet.

[0017] The beneficial effects of this invention are as follows: In use, the traction column is pushed to move the magnetic rod out of the positioning slot of the activation groove and into the acupuncture needle storage cavity through the needle outlet channel corresponding to the acupuncture needle of the required needle type; after the magnetic rod attracts the acupuncture needle in the acupuncture needle storage cavity, the traction column is pushed to reset the magnetic rod and the position of the elastic holding roller is adjusted so that the elastic holding roller, the magnetic rod and the threaded roller form a triangle to clamp the acupuncture needle; the drive unit runs and drives the threaded roller to rotate, and the friction provided by the thread on the threaded roller to the acupuncture needle causes the acupuncture needle to move towards the needle outlet. The acupuncture needle slowly rotates and inserts into the position to be needled. When the tail end of the acupuncture needle disengages from the threaded roller, the acupuncture needle insertion is completed.

[0018] The magnetic acupuncture device of this application uses a semi-circular acupuncture needle cylinder, which can store multiple types of acupuncture needles in different needle storage cavities at a time. Furthermore, the acupuncture needle cylinder is connected to the acupuncture needle activation part located at the axis via multiple needle outlet plates. This structural layout leaves an observation area, facilitating the viewing of the needle insertion position during acupuncture and also serving as a positioning tool during observation. The device relies on magnetic rods to retrieve needles through different needle outlet channels, making operation convenient and preventing needle leakage. The magnetic rods attract and retrieve the acupuncture needles, while the needles remain on the surface of the magnetic rods. The needles are rollable, allowing for flexible needle removal and preventing them from falling off at the junctions of the needle storage cavity and the needle outlet channel, or between the needle outlet channel and the activation groove. During the insertion phase, the elastic holding roller provides elastic pressure to the needles, while the magnetic rod holds the needles in place to prevent them from falling off during the adjustment of the elastic holding roller. Finally, the triangular clamping of the needles by the elastic holding roller, magnetic rod, and threaded roller ensures the stability of the needle insertion and adaptability to different needle sizes. This is the key to stable insertion of needles of different sizes. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0025] The magnetic acupuncture device of the preferred embodiment of the present invention, such as Figure 1 As shown, see also Figures 2-4 The device includes a semi-circular acupuncture needle cylinder 1 and an acupuncture needle activation part located at the axis of the acupuncture needle cylinder 1. Multiple acupuncture needle storage cavities 10 are distributed on the acupuncture needle cylinder 1 in an arc-shaped configuration. The acupuncture needle cylinder 1 and the acupuncture needle activation part are connected by multiple longitudinal needle outlet plates 3, each containing a transverse needle outlet channel 30. The acupuncture needle activation part includes a cylinder 20, with multiple needle outlet channels 30 communicating with the cylinder 20. Each acupuncture needle storage cavity 10 is connected to a corresponding needle outlet channel 30. The width of each needle outlet channel 30 is preferably designed to be 1.5-2 times the outer diameter of the tail end of the acupuncture needle 4 stored in the corresponding acupuncture needle storage cavity 10. A magnetic rod 21, which can pass through the needle outlet channels 30 and attract acupuncture needles within the acupuncture needle storage cavity 10, is provided inside the cylinder 20. The acupuncture needle 22 has multiple needle outlet channels 30. The upper end of the magnetic rod 21 is provided with a traction column 23. The upper end of the cylinder 20, the upper end of the multiple needle outlet plates 3, and the upper end of the acupuncture needle cylinder 1 are all provided with sliding grooves for the traction column 23 to slide, and adjacent sliding grooves are connected. The inner walls of the left and right sides of the acupuncture needle 22 are respectively provided with elastic holding rollers 25 and threaded rollers 26. The front side of the acupuncture needle 22 is connected to the multiple needle outlet channels 30. The inner wall of the rear side of the acupuncture needle 22 is provided with a V-shaped positioning groove 220 for positioning the magnetic rod 21. The lower end of the cylinder 20 is provided with a needle outlet. The acupuncture needle acupuncture part is provided with an adjustment unit 27 for adjusting the position of the elastic holding roller 25 and a drive unit 28 for driving the threaded roller 26 to rotate. The surface of the threaded roller 26 is provided with drive threads.

[0026] In use, the traction column 23 is pushed to move the magnetic rod 21 out of the positioning slot 220 of the activation slot 22 and into the acupuncture needle storage cavity 10 through the needle outlet channel 30 corresponding to the acupuncture needle of the required needle type. After the magnetic rod 21 attracts the acupuncture needle in the acupuncture needle storage cavity 10 (limited by the width of the needle outlet channel, only one acupuncture needle can be attracted at a time), the traction column 23 is pushed to reset the magnetic rod 21 and the position of the elastic holding roller 25 is adjusted so that the elastic holding roller 25, the magnetic rod 21 and the threaded roller 26 form a triangle to clamp the acupuncture needle. The drive unit 28 runs and drives the threaded roller 26 to rotate. The friction provided by the thread on the threaded roller 26 to the acupuncture needle 4 causes the acupuncture needle 4 to move towards the needle outlet. The acupuncture needle 4 slowly rotates and inserts into the position to be needled. When the tail end of the acupuncture needle 4 leaves the threaded roller, the acupuncture needle 4 is inserted.

[0027] The magnetic acupuncture device of this application uses a semi-circular acupuncture needle cylinder 1, which can store multiple types of acupuncture needles 4 in different acupuncture needle storage cavities 10 at a time. In addition, the acupuncture needle cylinder 1 is connected to the acupuncture needle activation part located at the axis through multiple needle outlet plates 3. This structural layout can leave an observation area, which is convenient for checking the needle position when needling, and at the same time plays a role in positioning during observation.

[0028] The acupuncture needle 4 is retrieved through different needle outlet channels 30 by magnetic rod 21. The operation is convenient and the needle will not leak out. While magnetic rod 21 attracts and retrieves the acupuncture needle 4, the acupuncture needle 4 can roll on the surface of magnetic rod 21. This allows for flexible needle retrieval and prevents the needle from falling off at the junction of acupuncture needle storage cavity 10 and needle outlet channel 30 or the junction of needle outlet channel 30 and activation groove 22. At the same time, during the needle insertion stage, elastic holding roller 25 elastically holds the acupuncture needle 4, and magnetic rod 21 attracts the acupuncture needle 4 to prevent the acupuncture needle from falling off during the adjustment of position of elastic holding roller 25 (contact with the acupuncture needle). Finally, the acupuncture needle 4 is held in a triangle by elastic holding roller 25, magnetic rod 21 and threaded roller 26 to ensure the stability of acupuncture needle insertion and adaptability to acupuncture needles of different sizes. This is the key to stable needle insertion for different sizes of needles.

[0029] Meanwhile, throughout the entire acupuncture process, the acupuncture needles 4 do not come into direct contact with the hands of medical staff to avoid contamination of the acupuncture needles by human hands.

[0030] Preferably, the lower end of the cylinder 20 is lower than the lower end of the needle plate 3. The drive unit 28 includes a micro motor 280, a battery 281, and a control switch 282. The micro motor 280 is inverted and mounted on the outer surface of the cylinder 20. The threaded roller 26 is connected to the movable end of the micro motor 280 through a reduction gearbox 283. The cylinder 20 has a slot for mounting the reduction gearbox 283. The drive structure is simple and the size can be small, while providing a large output torque to ensure the reliability of needle output.

[0031] Preferably, the adjustment unit 27 and the drive unit 28 are located on the left and right sides of the cylinder 20, respectively. The adjustment unit 27 includes a lever 270 and a Y-shaped bracket 271 that is damped and rotatably connected to the cylinder 20. The two ends of the rotating shaft of the elastic pressure roller 25 are respectively connected to the Y-shaped bracket 271 by springs 272. One end of the lever 270 is connected to the Y-shaped bracket 271, and the other end passes through the cylinder 20. By pushing and pulling the lever by hand, the position of the Y-shaped bracket can be easily controlled, that is, the position adjustment of the elastic pressure roller 25 can be realized. The overall structure is simple and easy to assemble.

[0032] Preferably, a guide section 221 is provided at the front side of the excitation groove 22 where it connects with the multiple needle outlet channels 30. The width of the guide section 221 is approximately equal to the outer diameter of the magnetic rod 21. The outer diameter of the magnetic rod 21 is larger than the outer diameter of the tail end of the acupuncture needle 4, and the outer diameter of the magnetic rod 21 is smaller than the width of the needle outlet channel 30. The unique design of the guide section 221 aims to ensure that after the magnetic rod 21 passes through the guide section 221, the acupuncture needle 4 attracted on the magnetic rod 21 is located at the front side of the magnetic rod 21. In this way, after the magnetic rod 21 enters the positioning groove 220, the acupuncture needle 4 attracted on the magnetic rod 21 is located exactly in the middle position of the elastic holding roller 25, the magnetic rod 21 and the threaded roller 26, which facilitates the smooth operation of subsequent holding operations.

[0033] Preferably, an acupuncture needle baffle 31 is provided in the needle outlet channel 30. The acupuncture needle baffle 31 is set on the inner wall of the needle outlet channel 30 by rotating laterally via a rotating shaft. A torsion spring is sleeved on the rotating shaft to reset the acupuncture needle baffle 31; to prevent the acupuncture needle 4 in the acupuncture needle storage cavity 10 from accidentally rolling into the activation groove 22.

[0034] Preferably, both the cylinder 20 and the needle ejection plate 3 are made of transparent or semi-transparent materials to facilitate observation of needle removal and ejection.

[0035] Preferably, the multiple needle plates 3 are radially distributed around the axis of the acupuncture needle cylinder 1.

[0036] A method for inserting needles into a magnetic acupuncture device, applied to the magnetic acupuncture device as described above, includes the following steps:

[0037] Push the traction column to move the magnetic rod out of the positioning slot of the activation slot and into the acupuncture needle storage cavity through the needle outlet channel corresponding to the acupuncture needle of the required needle type;

[0038] After the magnetic rod attracts the acupuncture needle in the acupuncture needle storage cavity, the traction column is pushed to reset the magnetic rod, and the position of the elastic holding roller is adjusted so that the elastic holding roller, the magnetic rod and the threaded roller form a triangle to clamp the acupuncture needle.

[0039] The drive unit operates to drive the threaded roller to rotate, and the friction provided by the threads on the threaded roller to the acupuncture needle causes the acupuncture needle to move toward the needle outlet.

[0040] Using the method of this application, a semi-circular acupuncture needle cylinder is used, which can store multiple types of acupuncture needles in different acupuncture needle storage cavities at one time. In addition, the acupuncture needle cylinder is connected to the acupuncture needle activation part located at the axis through multiple needle outlet plates. This structural layout can leave an observation area, which is convenient for checking the needle position when needling, and at the same time plays a role in positioning during observation.

[0041] Using magnetic rods, needles are retrieved through different needle outlet channels, making operation convenient and preventing needle leakage. While the magnetic rods attract and retrieve the acupuncture needles, the needles can roll on the surface of the magnetic rods, allowing for flexible needle retrieval and preventing detachment at the junctions of the needle storage cavity and the outlet channel, or between the outlet channel and the activation groove. During the insertion stage, elastic holding rollers provide elastic support for the acupuncture needles, and the magnetic rods hold the needles in place, preventing them from falling off during the adjustment of the elastic holding rollers (in contact with the acupuncture needles). Finally, the elastic holding rollers, magnetic rods, and threaded rollers form a triangular clamp to hold the acupuncture needles, ensuring the stability of the insertion and adaptability to different needle sizes. This is the key to stable insertion of needles of different sizes.

[0042] Meanwhile, throughout the entire acupuncture process, the acupuncture needles do not come into direct contact with the hands of medical staff to avoid contamination of the acupuncture needles by human hands.

[0043] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
