Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a wrist-ankle needle positioning device and its storage box. Background Technology

[0002] Wrist-ankle acupuncture is a treatment method that uses acupuncture needles to perform superficial subcutaneous needling at specific acupuncture points on the wrist and ankle along the longitudinal axis of the limb. By stimulating the skin, it adjusts the functions of the corresponding meridians and internal organs, promotes the smooth flow of qi and blood, and thus achieves the effects of promoting blood circulation, removing blood stasis, clearing the meridians, and relieving pain.

[0003] When performing wrist-ankle acupuncture in clinical practice, the width of the patient's finger is usually measured with a cotton swab. Then, the cotton swab is placed on the patient's wrist or ankle to compare the distance of the acupoint from the wrist crease or ankle. After that, the acupoint is determined by checking the position of the ulnar and radial borders. The acupoint is then marked with a pen to facilitate the subsequent acupuncture procedure. Marking the location of the acupoint with a pen leaves a mark on the skin that is not easy to remove. When the sharp pen tip comes into contact with the skin, it can also cause discomfort to the patient.

[0004] Patent CN217366521U discloses a wrist-ankle acupuncture implantation auxiliary zoning device. This device resembles a flexible ruler with graduations and a sliding indicator strip to mark acupoints. However, when in use, the indicator strip is aligned with the direction of the needle insertion. If the indicator strip is directly pointing at the acupoint, it can obstruct the needle's path. Therefore, the indicator strip needs to be slightly offset from the acupoint, but this can cause inaccurate acupoint positioning. Inexperienced operators may easily miss the acupoint during needle insertion. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] The following is based on Figures 1-14 This invention describes the wrist and ankle needle positioning device and its storage box provided in an embodiment of the present invention.

[0036] On the one hand, this utility model provides a wrist-ankle needle positioning device.

[0037] Example 1:

[0038] Please see Figure 1 - Figure 2 This utility model discloses a wrist-ankle pin positioning device, including a wristband assembly 2, which is elongated and composed of a braided band 201 and a flexible strip 202, and is used to wrap around and fix to the wrist or ankle. When fixed to the wrist, the edge of the wristband assembly 2 needs to be close to the wrist crease. When fixed to the ankle, the edge of the wristband assembly 2 needs to cover the medial and lateral malleoli. It also includes a positioning fork 3, which is a fork-shaped structure with one end open and the other end closed, forming a U-shaped structure. The positioning fork 3 can be made of PC plastic or stainless steel to give it a certain degree of rigidity. There is a gap space 31 between the two forks. The positioning fork 3 can be fixed to the braided band 201. The fixed position of the positioning fork 3 on the braided band 201 is variable. The positioning fork 3 can be adjusted along the length and / or width of the braided band 201.

[0039] It also includes a positioning ring 4, which is an open ring. The two ends of the positioning ring 4 are fixed to the ends of the two forks of the positioning fork 3, i.e., the open ends of the U-shaped structure. The positioning ring 4 is used to mark the position of the acupoint. The positioning ring 4 is preferably made of stainless steel and the inner diameter of the positioning ring 4 is preferably 0.3mm-0.8mm.

[0040] In this implementation scheme, for example, if needles need to be implanted in the wrist, the wristband assembly 2 needs to be fixed in the wrist first. Then, the position of the acupoint along the length of the wristband assembly 2 is determined according to the position of the ulnar and radial edges (the specific determination method is clearly explained in the industry and will not be elaborated here). Then, according to the patient's finger width, the width of two fingers is taken (if it is the ankle, the width of three fingers is generally taken). This width is used as the distance from the center of the positioning ring 4 to the wrist crease. At this time, the positioning fork 3 can be fixed to the corresponding position on the wristband assembly 2 according to the position of the positioning ring 4. When implanting the needle, the needle tip is inserted under the skin from the positioning ring 4. The needle handle can move in the gap space 31 of the positioning fork 3. When multiple needles need to be implanted, multiple positioning forks 3 and positioning rings 4 can be used to position them separately. Compared with marking the position of the acupoint by drawing dots on the skin with a marker, this device will not leave a mark on the skin, and the positioning fork 3 and positioning ring 4 will not obstruct or hinder the field of vision and the position of the needle implantation.

[0041] Combination Figure 1 , Figure 2 and Figure 4 To facilitate observation of the distance between the positioning ring 4 and the wrist crease, a positioning line 22 is fixed on the surface of the braided belt 201 near the positioning fork 3. The positioning line 22 is set along the edge of the braided belt 201 along its length, i.e., the positioning line 22 is set on the edge of the braided belt 201. This ensures that when the edge of the wristband assembly 2 is close to the wrist crease, the positioning line 22 is exactly above the wrist crease. For ease of use, two positioning lines 22 can be set, located on the two edges on both sides of the braided belt 201. Preferably, the positioning line 22 is a line woven on the braided belt 201, and the color of the line is different from the color of the braided belt 201.

[0042] Furthermore, a scale line 5 is provided on the surface of the positioning fork 3. The scale line 5 takes the center of the positioning ring 4 as the starting measurement position. The patient's finger width can be measured by a ruler 1. After measuring the determined finger width value, the positioning fork 3 is moved in the width direction until the vertical distance from the center of the positioning ring 4 to the positioning line 22 is equal to the measured value. During this process, the scale line 5 can provide a relatively clear position reference.

[0043] Combination Figure 2 and Figure 3 Since both the wristband assembly 2 and the positioning fork 3 have a certain thickness, the positioning ring 4 fixed on the positioning fork 3 will be at a certain height from the skin during use. This will cause the needle to be inserted at a different angle when the needle is inserted at an angle, which will result in a positioning deviation. In order to reduce this effect, a bent section 41 is provided at the end where the positioning ring 4 is connected to the positioning fork 3. The bent section 41 bends away from the scale line 5, thereby reducing the height of the positioning ring 4 relative to the positioning fork 3, so that the positioning ring 4 is closer to the skin during use.

[0044] Combination Figure 1 , Figure 4 and Figure 5 In this embodiment, the flexible strip 202 is made of rubber or silicone. The flexible strip 202 is fixed to the surface of the braided belt 201 facing the positioning fork 3. When it is fixed around the wrist or ankle, the flexible strip 202 is on the side away from the skin. A groove 2021 is provided on the surface of the flexible strip 202 near the positioning fork 3. A sliding platform 8 is slidably provided in the groove 2021. The sliding platform 8 can slide in the groove 2021 and has a certain resistance when sliding. When the sliding platform 8 is not subjected to a sufficiently large external force, it will always be in a stationary state. In order to prevent the sliding platform 8 from falling out of the groove 2021, it is preferable to fix flanges 82 on both sides of the sliding platform 8. Correspondingly, matching through grooves are provided on both sides of the groove 2021 so that the sliding platform 8 can still be stuck in the groove 2021 when subjected to an upward force.

[0045] Furthermore, a boss 81 is fixed on the surface of the sliding table 8 near the positioning fork 3, and a positioning block 6 is provided in the gap space 31 between the two forks of the positioning fork 3. The positioning block 6 can be fixed or slid within the gap space 31, so that the positioning block 6 can move or remain stationary relative to the positioning fork 3. A groove 63 is provided on the surface of the positioning block 6 near the sliding table 8. The groove 63 fits with the boss 81 so that the boss 81 is inserted into the groove 63. When the boss 81 is inserted into the groove 63, the sliding table 8 slides, which can drive the positioning fork 3 to move together.

[0046] When the wristband assembly 2 is wrapped around the wrist or ankle, it is oval in shape and has a large bend at the intersection of the two sides. Therefore, when the sliding table 8 slides, it needs to slide on one side to avoid getting stuck at the bend.

[0047] Additionally, refer to Figure 1 In order to facilitate the adjustment of the effective length of the braided tape 201, a buckle 21 is connected to one end of the braided tape 201, and the other end of the braided tape 201 can be inserted into the buckle 21. Preferably, the buckle 201 is a double-ring buckle.

[0048] This implementation plan (in conjunction with) Figure 5 and Figure 8 To make the connection between the sliding table 8 and the positioning block 6 more secure, a first magnet 7 can be set inside the positioning block 6 and a second magnet 9 can be set inside the sliding table 8. This way, when the boss 81 is inserted into the recess 63, the connection strength can be enhanced by the mutual attraction between the first magnet 7 and the second magnet 9, and it is also convenient to separate the sliding table 8 and the positioning block 6.

[0049] Combination Figure 5 - Figure 7A slot 32 is provided on the side of the fork 3 facing the gap space 31. Since there are two forks, two sets of slot 32 are also provided accordingly, and the two sets of slot 32 are opposite to each other.

[0050] Furthermore, an inverted groove 61 is provided on both sides of the positioning block 6. The inverted groove 61 clamps the positioning fork 3, so that the positioning block 6 will not detach from the gap space 31 when sliding. A receiving groove 64 is provided on the side of the inverted groove 61 opposite to the groove tooth 32. A limiting spring piece 62 is fixed in the receiving groove 64. The limiting spring piece 62 fits with the groove tooth 32. When the position of the positioning fork 3 is restricted, the limiting spring piece 62 will be stuck in the recess of the groove tooth 32 when the positioning block 6 is not pushed. When the positioning block 6 is pushed along the length direction of the positioning fork 3, the limiting spring piece 62 will be pressed by the protrusion of the groove tooth 32 and shift into the receiving groove 64, thereby passing over the protrusion of the groove tooth 32. Then, the positioning block 6 can move in the gap space 31 when subjected to external force. Correspondingly, when the position of the positioning block 6 is restricted and the positioning fork 3 is pushed, the same effect will be achieved.

[0051] In this embodiment, when using the positioning fork 3 and the positioning ring 4, the positioning block 6 can be fixed to the sliding table 8. By moving the sliding table 8, the positioning fork 3 can be moved to the position of the acupoint along the length of the wristband assembly 2. Then, by pushing the positioning fork 3, the positioning ring 4 can be moved to the position of the acupoint.

[0052] Example 2:

[0053] Combination Figure 9 and Figure 10 The difference between this embodiment and Embodiment 1 is that the wristband assembly 2 is composed of a braided strap 201, a first hook and loop fastener 203, and a second hook and loop fastener 204. The first hook and loop fastener 203 is a hook side, and the second hook and loop fastener 204 is a loop side. The first hook and loop fastener 203 is fixed to the surface of the braided strap 201 facing the positioning fork 3, and the second hook and loop fastener 204 is fixed to the surface of the braided strap 201 away from the positioning fork 3. When it is necessary to wrap the wristband assembly 2 around the wrist or ankle, the second hook and loop fastener 204 can be wrapped around once and then directly pasted onto the first hook and loop fastener 203. The reason for making the side away from the skin a hook side is to avoid irritation to the skin.

[0054] Combination Figure 11 In order to facilitate the fixing of the positioning fork 3, a third hook and loop fastener 33 is fixed on the surface of the positioning fork 3 away from the scale line 5. The third hook and loop fastener 33 has a rough surface so that it can be pasted onto the first hook and loop fastener 203. The outline of the third hook and loop fastener 33 fits the surface of the positioning fork 3 to avoid obstructing the gap space 31 and thus hindering the embedding of the needle.

[0055] On the other hand, reference Figure 12 - Figure 14 The present invention also provides a storage box for storing the above-mentioned wrist and ankle pin positioning device, including a box body 10 and a box cover 11. The box cover 11 is hinged to one side of the box body 10. The box body 10 and the box cover 11 are preferably made of stainless steel.

[0056] A first storage slot 12 is provided on the box body 10. The first storage slot 12 is used to place the woven strap 201. The woven strap 201 can be placed into the first storage slot 12 after being folded. A second storage slot 13 is also provided on the box body 10. The second storage slot 13 is used to place the ruler 1 so that the ruler 1 can be easily taken out.

[0057] Furthermore, an elastic pressure plate 15 is fixedly provided on the box body 10, and the elastic pressure plate 15 has at least one ( Figure 12 and Figure 13 There are 6 of them. One end of the elastic pressure plate 15 is the open end 151 and the other end is the closed end 152. The open end 151 is close to the surface of the box body 10, and the bottom surface of the closed end 152 is fixed to the box body 10, so that there is a certain space between the elastic pressure plate 15 and the surface of the box body 10. The positioning ring 4 can be inserted into the elastic pressure plate 15 from the open end 151, that is, into the space between the elastic pressure plate 15 and the surface of the box body 10, so that the elastic pressure plate 15 can limit the positioning fork 3, so that multiple positioning forks 3 can be placed in the box body 10 in an orderly manner for easy access. Preferably, the side of the closed end 152 near the open end 151 is an arc-shaped structure to match the curvature of the positioning ring 4 and avoid deformation of the positioning ring 4.

[0058] Combination Figure 13 and Figure 14 A groove 14 is provided on the surface of the box body 10. The width of the groove 14 is greater than the diameter of the positioning ring 4, and the depth of the groove 14 is not greater than the height of the elastic pressure plate 15. At this time, the bottom surface of the closed end 152 is fixedly connected to the bottom surface of the groove 14. The groove 14 is used to accommodate the positioning ring 4. Since the positioning ring 4 has a bent section 41 near the positioning fork 3, the groove 14 can be used to offset the height difference between the positioning ring 4 and the positioning fork 3 caused by the bent section 41, so that the positioning fork 3 can be placed approximately parallel in the box body 10, so as to avoid the elastic pressure plate 15 bending the positioning ring 4 when the positioning fork 3 is placed at an angle.

[0059] The working principle and usage process of this utility model are as follows: When using it, first fix the wristband assembly 2 on the wrist so that the positioning line 22 on the side closest to the wrist crease is exactly above the wrist crease. Then take out a positioning fork 3 and insert the boss 81 into the groove 63. Then determine the position of the acupoint along the length of the wristband assembly 2 according to the position of the ulnar edge and the radial edge. Then move the sliding platform 8 to drive the positioning fork 3 to move together. Move the positioning fork 3 to the position of the acupoint along the length of the wristband assembly 2. Then measure the width of two fingers with a ruler 1. Then push the positioning fork 3 and observe the scale line 5 on the positioning fork 3 until the distance from the center of the positioning ring 4 to the positioning line 22 is the same as the measured width value. At this time, the position of the positioning ring 4 is the position of the acupoint. When embedding the needle, the needle tip is inserted under the skin from the positioning ring 4, and the needle handle can move in the gap space 31 of the positioning fork 3.

[0060] In summary, this wrist-ankle acupuncture positioning device and its storage box, by setting a positioning fork 3 that can be fixed to the wristband assembly 2, and the fixed position of the positioning fork 3 on the wristband assembly 2 is adjustable, and a positioning ring 4 is fixed at the end of the fork 3, can mark the position of acupoints by the cooperation of the positioning fork 3 and the positioning ring 4. Compared with marking the position of acupoints by drawing dots on the skin with a marker, this device will not leave marks on the skin, and the positioning fork 3 and the positioning ring 4 will not obstruct or hinder the field of vision and insertion position of the needle. By setting multiple elastic pressure plates 15 on the box body 10, multiple positioning forks 3 can be limited, so that multiple positioning forks 3 can be placed in the box body 10 in an orderly manner for easy access.
