Description

Technical Field

[0001] This invention relates to traditional Chinese medicine nursing techniques, specifically to a wrist-ankle acupuncture insertion auxiliary fixation device for traditional Chinese medicine nursing. Background Technology

[0002] Wrist and ankle acupuncture TCM nursing refers to a minimally invasive, safe, and painless external TCM treatment technique that involves inserting disposable sterile acupuncture needles at approximately a 30° angle into a specific area of ​​the patient's wrist or ankle, guided by TCM meridian theory. During needle retention, no lifting, thrusting, or twisting techniques are used. This superficial stimulation activates the body's self-regulating functions, thereby achieving the effects of unblocking meridians, harmonizing qi and blood, relieving pain, and balancing yin and yang. It is widely used as an adjunct treatment and nursing intervention for common conditions such as insomnia, pain, anxiety, and dizziness.

[0003] Wrist-ankle acupuncture, a commonly used superficial needling therapy in traditional Chinese medicine nursing, requires the needle to be inserted quickly into the subdermal layer at an angle of approximately 30° to the skin. However, clinical operation relies entirely on the manual experience of medical staff, as there are no dedicated positioning instruments. The wrist and ankle are arc-shaped, and the skin tension varies greatly in different directions. When holding the needle, the fulcrum is unstable and the line of sight is obstructed, making it difficult to accurately reproduce the 30° angle in one go. Often, the angle is too large, penetrating the muscle layer, or too shallow, remaining in the epidermis, leading to decreased efficacy, increased pain, and repeated needle insertion, increasing patient suffering and the risk of infection. There is an urgent need for an auxiliary device that can quickly fix and accurately guide the needle insertion at a 30° angle. Summary of the Invention

[0004] The purpose of this invention is to provide a wrist-ankle acupuncture insertion auxiliary fixation device for traditional Chinese medicine nursing, so as to solve the problem that the existing technology lacks a dedicated positioning device when inserting wrist-ankle acupuncture needles, making it difficult for medical staff to stably and accurately control the 30° insertion angle, resulting in large angle errors, repeated punctures, and increased patient pain.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wrist-ankle acupuncture insertion auxiliary fixation device for traditional Chinese medicine nursing, comprising:

[0006] A clip is used to secure the patient's wrist and ankle.

[0007] The connecting block is fixed to the outer wall of the ferrule;

[0008] Damping sleeve, fixed at an angle to the connecting block;

[0009] The needle insertion assembly, with damping inserted into the damping sleeve, includes:

[0010] cylindrical body;

[0011] The first needle cannula is fixed at the tail end of the cylinder and extends into the cylinder body;

[0012] The second needle sleeve is screwed to the first needle sleeve via external threads. It is used to adjust the length to accommodate the needle body, and its tail end extends into the damping sleeve.

[0013] The cavity is fixed inside the cylinder.

[0014] The shaft has its rear end movably located inside the cavity, and its front end is fixed with a top pressure plate.

[0015] A spring is sleeved on the outer wall of the shaft and located between the top pressure plate and the cavity.

[0016] The paddle is symmetrically fixed on the outer periphery of the top pressure plate and slides in conjunction with a slot opened on the outer wall of the cylinder. The slot is provided with several latches at intervals along the length direction to lock the paddle to store or release spring potential energy.

[0017] Furthermore, the axis of the damping sleeve forms a 30° acute angle with the horizontal plane.

[0018] Furthermore, it also includes a V-shaped opening and closing mechanism, wherein the V-shaped opening and closing mechanism is symmetrically fixed to the outer wall of the damping sleeve, including a first connecting rod, a second connecting rod rotatably connected to the first connecting rod via a damping shaft, and a semi-circular plate fixed to the ends of the two second connecting rods. When the two semi-circular plates are closed, they block the front end of the damping sleeve to prevent the needle from falling off. When the second needle sleeve moves forward and pushes the semi-circular plate, the V-shaped structure opens and the end of the needle rests on the skin to expose the needle and complete the 30° fixed angle needle insertion.

[0019] Furthermore, a semi-conical hole is provided on the upper wall of the semi-circular plate to avoid the tip of the needle when it opens, thereby reducing frictional resistance.

[0020] Furthermore, the outer wall of the cylinder is provided with scale lines, which correspond one-to-one with the position of the bayonet, and are used to indicate the spring compression amount in order to control the needle feeding depth.

[0021] Furthermore, the ferrule is a C-shaped elastic polypropylene open ring.

[0022] Furthermore, the front end face of the top pressure plate is provided with a groove that matches the tail end of the needle handle, which is used to center the needle body axially and uniformly transmit the spring thrust.

[0023] Furthermore, a plurality of mounting rings are fixedly provided on the outer wall of the cavity, and a plurality of support rods are fixedly connected to the outer wall of the mounting rings, with one end of each of the support rods being fixedly connected to the inner wall of the cavity.

[0024] Furthermore, a limiting disc is fixedly provided at the rear end of the shaft, and the limiting disc is movably connected to the cavity groove of the cavity, and the outer diameter of the limiting disc is larger than the outer diameter of the shaft.

[0025] Compared with existing technologies, this invention provides a wrist-ankle acupuncture insertion auxiliary fixation device for TCM nursing. The ferrule is connected to the patient's wrist and ankle through an elastic embrace to form a stable base; the damping sleeve is fixed at an angle by the connecting block, becoming a "rigid guide rail" for needle insertion. During needle insertion, the lever is first pulled back along the groove and locked into the corresponding slot, and the spring is compressed to store energy; when the lever is released, the spring potential energy is instantly converted into the linear kinetic energy of the shaft, and the top pressure plate pushes the needle body out along the inclined channel formed by the first needle sleeve and the second needle sleeve, so that it quickly pierces the subdermal layer at a constant angle, avoiding the angle deviation caused by the instability of the fulcrum by freehand, and realizing the wrist-ankle acupuncture operation of "one-time positioning and one-time needle insertion";

[0026] After the spring has been charged, the operator inserts the needle into the first and second needle cannulas. The device is then inverted so that the opening of the second needle cannulas faces upward. Next, the second needle cannulas is connected to the damping cannulas, so that the two closed semicircular plates seal the port of the second needle cannulas, preventing the needle from coming out of the second needle cannulas before positioning. Then, the ferrule is placed on the patient's wrist and ankle to position the needle insertion angle. At this point, when the medical staff moves the second needle cannulas down and pushes the semicircular plates, the V-shaped structure opens and the end of the needle rests against the skin, so that the elastic potential energy can be released for subsequent needle insertion.

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] As attached Figure 1 To be continued Figure 7 As shown:

[0039] Example 1:

[0040] This invention provides a wrist-ankle acupuncture insertion auxiliary fixation device for traditional Chinese medicine nursing, comprising:

[0041] Sleeve 1, used to secure it to the patient's wrist and ankle;

[0042] Connecting block 11 is fixed to the outer wall of sleeve 1;

[0043] Damping sleeve 2 is fixed at an angle to connecting block 11;

[0044] The needle insertion assembly 3 is damped and inserted into the damping sleeve 2. The needle insertion assembly 3 includes:

[0045] Cylinder 31;

[0046] The first needle sleeve 32 is fixed to the tail end of the cylinder 31 and extends into the cylinder 31;

[0047] The second needle sleeve 33 is screwed to the first needle sleeve 32 via external threads and is used to adjust the length to accommodate the needle body. Its tail end extends into the damping sleeve 2.

[0048] Cavity 34 is fixed inside cylinder 31.

[0049] The shaft 35 has its rear end movably disposed inside the cavity 34, and its front end is fixed with the top pressure plate 36.

[0050] Spring 37 is sleeved on the outer wall of shaft 35 and located between top pressure plate 36 and cavity 34;

[0051] The paddle 38 is symmetrically fixed on the outer periphery of the top pressure plate 36 and slides in cooperation with the slot 311 opened on the outer wall of the cylinder 31. The slot 311 is provided with several latches 312 at intervals along the length direction to lock the paddle 38 to store or release the potential energy of the spring 37.

[0052] Specifically, the axis of the damping sleeve 2 forms a 30° acute angle with the horizontal plane.

[0053] As can be seen from the above, the ferrule 1 is connected to the patient's wrist and ankle through an elastic embrace, forming a stable base; the damping sleeve 2 is fixed at a 30° angle by the connecting block 11, becoming a "rigid guide rail" for needle insertion. When inserting the needle, the lever 38 is first pulled back along the groove 311 and inserted into the corresponding slot 312, and the spring 37 is compressed and stored energy; when the lever 38 is released, the potential energy of the spring 37 is instantly converted into the linear kinetic energy of the shaft 35, and the top pressure plate 36 pushes the needle body out along the 30° channel formed by the first needle sleeve 32 and the second needle sleeve 33, so that it quickly pierces the subdermal layer at a constant 30° angle, avoiding the angle deviation caused by the instability of the fulcrum by freehand, and realizing the wrist and ankle needle operation of "one positioning and one needle insertion".

[0054] As attached Figure 1 As shown, the ferrule 1 is a C-shaped elastic polypropylene open ring.

[0055] As can be seen from the above, the elastic modulus of the C-shaped elastic polypropylene open ring is ≥1.2 GPa. The inner side can be evenly distributed with 0.5 mm protrusions to increase the friction coefficient to 0.4, prevent the ring from rotating or slipping, and keep the damping sleeve 2 always located at the midline of the wrist and ankle. This ensures that the 30° needle insertion direction is perpendicular to the long axis of the limb and avoids the angle deviation caused by the displacement of the ring.

[0056] As attached Figure 3 As shown, a plurality of mounting rings 51 are fixedly provided on the outer wall of the cavity 34, and a plurality of support rods 52 are fixedly connected to the outer wall of the mounting rings 51, and one end of each of the support rods 52 is fixedly connected to the inner wall of the cylinder 31.

[0057] As can be seen from the above, the mounting ring 51 and the support rod 52 fix the cavity 34 to the center of the cylinder 31, making the cavity 34 and the cylinder 31 coaxial, thus avoiding the generation of eccentric bending moment during the movement of the shaft rod 35.

[0058] As attached Figure 7 As shown, a limiting disk 351 is fixedly provided at the rear end of the shaft 35, and the limiting disk 351 is movably connected to the cavity groove of the cavity 34. The outer diameter of the limiting disk 351 is larger than the outer diameter of the shaft 35.

[0059] As can be seen from the above, the outer diameter of the limiting disc 351 is 4 mm larger than that of the shaft 35, and the gap between it and the inner cavity of the cavity 34 forms a piston guide; when the spring 37 releases its energy, the rear end of the limiting disc 351 strikes the bottom of the cavity 34, instantly stopping the displacement of the shaft 35, preventing overshoot from causing the needle body to continue to move forward, thereby achieving a hard limit of "stopping immediately after injection", and completing the smooth puncture of the wrist and ankle needle.

[0060] Example 2:

[0061] This invention provides a wrist-ankle acupuncture insertion auxiliary fixation device for traditional Chinese medicine nursing, comprising:

[0062] Sleeve 1, used to secure it to the patient's wrist and ankle;

[0063] Connecting block 11 is fixed to the outer wall of sleeve 1;

[0064] Damping sleeve 2 is fixed at an angle to connecting block 11;

[0065] The needle insertion assembly 3 is damped and inserted into the damping sleeve 2. The needle insertion assembly 3 includes:

[0066] Cylinder 31;

[0067] The first needle sleeve 32 is fixed to the tail end of the cylinder 31 and extends into the cylinder 31;

[0068] The second needle sleeve 33 is screwed to the first needle sleeve 32 via external threads and is used to adjust the length to accommodate the needle body. Its tail end extends into the damping sleeve 2.

[0069] Cavity 34 is fixed inside cylinder 31.

[0070] The shaft 35 has its rear end movably disposed inside the cavity 34, and its front end is fixed with the top pressure plate 36.

[0071] Spring 37 is sleeved on the outer wall of shaft 35 and located between top pressure plate 36 and cavity 34;

[0072] The paddle 38 is symmetrically fixed on the outer periphery of the top pressure plate 36 and slides in cooperation with the slot 311 opened on the outer wall of the cylinder 31. The slot 311 is provided with several latches 312 at intervals along the length direction to lock the paddle 38 to store or release the potential energy of the spring 37.

[0073] This embodiment is basically the same as the previous embodiment, except that, as shown in the appendix... Figure 1 Appendix Figure 4 and appendix Figure 5As shown, it also includes a V-shaped opening and closing mechanism 4. The V-shaped opening and closing mechanism 4 is symmetrically fixed to the outer wall of the damping sleeve 2, including a first connecting rod 41, a second connecting rod 43 rotatably connected to the first connecting rod 41 via a damping shaft 42, and a semi-circular plate 44 fixed to the ends of the two second connecting rods 43. When the two semi-circular plates 44 are closed, they block the front end of the damping sleeve 2 to prevent the needle from falling off. When the second needle sleeve 33 moves forward and pushes the semi-circular plate 44, the V-shaped structure opens and the end of the needle touches the skin to expose the needle and complete the 30° fixed angle needle insertion.

[0074] After the spring 37 has finished charging, the operator inserts the needle into the first needle sleeve 32 and the second needle sleeve 33, and then inverts the device so that the opening of the second needle sleeve 33 faces upward. Next, the second needle sleeve 33 is inserted into the damping sleeve 2, so that the two closed semicircular plates 44 seal the port of the second needle sleeve 33 to prevent the needle from coming out of the second needle sleeve 33 before positioning. Then, the ferrule 1 is put on the patient's wrist and ankle to complete the positioning of the needle insertion angle. At this time, when the medical staff moves the second needle sleeve 33 down and pushes the semicircular plate 44, the V-shaped structure opens and the end of the needle touches the skin so that the elastic potential energy can be released for subsequent needle insertion.

[0075] As can be seen from the above, during the inverted insertion process, the two closed semicircular plates 44 form a sealing force under the pre-tightening force of the damping shaft 42, which can prevent the needle body from slipping off due to gravity. When the oblique opening at the front end of the second needle cannula 33 pushes the semicircular plate 44, the V-shaped angle gradually widens, and the pushing force is decomposed into a tangential component, causing the semicircular plate 44 to rotate outward and open, allowing the needle tip to be exposed and placed against the skin entry point, realizing the continuous action of "positioning-exposure-needle insertion", avoiding the angle deviation caused by manually removing the cap.

[0076] Example 3:

[0077] This invention provides a wrist-ankle acupuncture insertion auxiliary fixation device for traditional Chinese medicine nursing, comprising:

[0078] Sleeve 1, used to secure it to the patient's wrist and ankle;

[0079] Connecting block 11 is fixed to the outer wall of sleeve 1;

[0080] Damping sleeve 2 is fixed at an angle to connecting block 11;

[0081] The needle insertion assembly 3 is damped and inserted into the damping sleeve 2. The needle insertion assembly 3 includes:

[0082] Cylinder 31;

[0083] The first needle sleeve 32 is fixed to the tail end of the cylinder 31 and extends into the cylinder 31;

[0084] The second needle sleeve 33 is screwed to the first needle sleeve 32 via external threads and is used to adjust the length to accommodate the needle body. Its tail end extends into the damping sleeve 2.

[0085] Cavity 34 is fixed inside cylinder 31.

[0086] The shaft 35 has its rear end movably disposed inside the cavity 34, and its front end is fixed with the top pressure plate 36.

[0087] Spring 37 is sleeved on the outer wall of shaft 35 and located between top pressure plate 36 and cavity 34;

[0088] The paddle 38 is symmetrically fixed on the outer periphery of the top pressure plate 36 and slides in cooperation with the slot 311 opened on the outer wall of the cylinder 31. The slot 311 is provided with several latches 312 at intervals along the length direction to lock the paddle 38 to store or release the potential energy of the spring 37.

[0089] This embodiment is basically the same as the previous embodiment, except that, as shown in the appendix... Figure 5 As shown, a semi-conical hole 441 is provided on the upper wall of the semi-circular plate 44 to avoid the tip of the needle body when it opens, thereby reducing frictional resistance.

[0090] As can be seen from the above, the conical surface provides a guiding slope for the needle tip at the moment of opening, reducing resistance.

[0091] Example 4:

[0092] This invention provides a wrist-ankle acupuncture insertion auxiliary fixation device for traditional Chinese medicine nursing, comprising:

[0093] Sleeve 1, used to secure it to the patient's wrist and ankle;

[0094] Connecting block 11 is fixed to the outer wall of sleeve 1;

[0095] Damping sleeve 2 is fixed at an angle to connecting block 11;

[0096] The needle insertion assembly 3 is damped and inserted into the damping sleeve 2. The needle insertion assembly 3 includes:

[0097] Cylinder 31;

[0098] The first needle sleeve 32 is fixed to the tail end of the cylinder 31 and extends into the cylinder 31;

[0099] The second needle sleeve 33 is screwed to the first needle sleeve 32 via external threads and is used to adjust the length to accommodate the needle body. Its tail end extends into the damping sleeve 2.

[0100] Cavity 34 is fixed inside cylinder 31.

[0101] The shaft 35 has its rear end movably disposed inside the cavity 34, and its front end is fixed with the top pressure plate 36.

[0102] Spring 37 is sleeved on the outer wall of shaft 35 and located between top pressure plate 36 and cavity 34;

[0103] The paddle 38 is symmetrically fixed on the outer periphery of the top pressure plate 36 and slides in cooperation with the slot 311 opened on the outer wall of the cylinder 31. The slot 311 is provided with several latches 312 at intervals along the length direction to lock the paddle 38 to store or release the potential energy of the spring 37.

[0104] This embodiment is basically the same as the previous embodiment, except that, as shown in the appendix... Figure 6 As shown, the outer wall of the cylinder 31 is provided with scale lines 313, and the scale lines 313 correspond one-to-one with the positions of the bayonet 312, which are used to indicate the compression amount of the spring 37 to control the needle feeding depth.

[0105] As can be seen above, the scale line 313 corresponds one-to-one with the locking slot 312. Each division represents an increase of 1 unit in the compression of the spring 37, which corresponds to an increase of the needle extension length by the same unit. Medical staff can select the locking slot 312 according to the thickness of the patient's subcutaneous fat to achieve controllable needle extension of 2–6 mm. This avoids the problem of traditional wrist and ankle acupuncture relying entirely on feel, which can result in either excessively deep insertion into the muscle layer or excessively shallow insertion into the epidermis, thus improving treatment consistency and safety.

[0106] Example 5:

[0107] This invention provides a wrist-ankle acupuncture insertion auxiliary fixation device for traditional Chinese medicine nursing, comprising:

[0108] Sleeve 1, used to secure it to the patient's wrist and ankle;

[0109] Connecting block 11 is fixed to the outer wall of sleeve 1;

[0110] Damping sleeve 2 is fixed at an angle to connecting block 11;

[0111] The needle insertion assembly 3 is damped and inserted into the damping sleeve 2. The needle insertion assembly 3 includes:

[0112] Cylinder 31;

[0113] The first needle sleeve 32 is fixed to the tail end of the cylinder 31 and extends into the cylinder 31;

[0114] The second needle sleeve 33 is screwed to the first needle sleeve 32 via external threads and is used to adjust the length to accommodate the needle body. Its tail end extends into the damping sleeve 2.

[0115] Cavity 34 is fixed inside cylinder 31.

[0116] The shaft 35 has its rear end movably disposed inside the cavity 34, and its front end is fixed with the top pressure plate 36.

[0117] Spring 37 is sleeved on the outer wall of shaft 35 and located between top pressure plate 36 and cavity 34;

[0118] The paddle 38 is symmetrically fixed on the outer periphery of the top pressure plate 36 and slides in cooperation with the slot 311 opened on the outer wall of the cylinder 31. The slot 311 is provided with several latches 312 at intervals along the length direction to lock the paddle 38 to store or release the potential energy of the spring 37.

[0119] This embodiment is basically the same as the previous embodiment, except that, as shown in the appendix... Figure 3 As shown, the front end face of the top pressure plate 36 is provided with a groove 361 that matches the tail end of the needle handle, which is used to center the needle body axially and uniformly transmit the thrust of the spring 37.

[0120] As can be seen from the above, after the groove 361 is assembled with the end of the needle body, a ball-and-socket fit is formed, which can evenly distribute the axial thrust of the spring 37 to the center of the needle handle, eliminate the lateral component force, and prevent the needle body from swaying; at the same time, the edge of the groove 361 can be rounded to avoid the shearing force from cutting off the end of the needle handle, ensuring that the instantaneous needle pushing force is transmitted in a straight line along the 30° track, and improving the puncture accuracy.

[0121] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
