Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical technology, and in particular to a novel soft tissue release needle that can be used both dry and wet. Background Technology
[0002] Myofascial pain syndrome (MPS) is considered a musculoskeletal disorder caused by localized tightness in areas of skeletal muscle and fascia (called trigger points). The lifetime prevalence of MPS in the general population is as high as 85%, with gender differences. MPS is often a chronic condition with a long course, leading to fibromyalgia, but acute exacerbations are also possible. Current treatments for MPS mainly include drug therapy (nonsteroidal anti-inflammatory drugs, tricyclic antidepressants, muscle relaxants, local anesthetics, botulinum toxin, etc.), wet acupuncture (trigger point injections), dry acupuncture (acupuncture, floating needle therapy, small needle knife therapy, etc.), myofascial release (direct and indirect myofascial release), and physical therapy (transcutaneous electrical nerve stimulation, interferential current therapy, electrophysiological feedback, etc.). Among these, wet and dry acupuncture are widely used clinically due to their minimal invasiveness, simplicity, rapid effectiveness, and low cost, achieving satisfactory clinical results.
[0003] Professor Travell first proposed the concept of dry needles in the 1940s, and later collaborated with Simons to formally include it in "Myofascial pain and dysfunction: The trigger point manual." Dry needles are the opposite of wet needles. Wet needles refer to needles that use hollow needles for drug injection, represented by ordinary syringes. They were first used to inject analgesics at trigger points to treat myofascial pain syndrome with satisfactory results. Dry needles, on the other hand, refer to needles that do not inject drugs, including hollow needles and solid needles. Currently, solid needles are more widely used in clinical practice. Representative solid needles include filiform needles, plum blossom needles, floating needles, and small needle knives. Among them, floating needles and small needle knives are products of the combination of traditional acupuncture medicine and Western basic medicine, and are widely used in clinical practice with clear effects.
[0004] Currently, wet acupuncture mainly uses ordinary syringes. Although drugs can be injected, the syringe needles are short and lack a holding point, making it difficult to effectively pry and loosen the needles, thus limiting its clinical application. As for dry acupuncture, the filiform needles are too thin and have a small holding point, making effective prying impossible. Floating needles and small needle knives can effectively pry and loosen the needles, but they do not have the effect of drug injection, and some patients experience recurrent pain.
[0005] In summary, current treatments for myofascial pain syndrome use needles with limited functionality. There are no needles on the market that combine dry and wet acupuncture. Current dry and wet acupuncture methods require two separate sets of needles, leading to more frequent treatments and higher costs for patients with different treatment needs.
[0006] Therefore, improvements must be made to address the aforementioned shortcomings. Utility Model Content

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0024] Reference Figures 1 to 2This utility model provides a novel dry and wet dual-purpose soft tissue release needle, comprising a plastic handle 2, wherein the plastic handle 2 has an L-shaped mounting cavity, the upper end of which penetrates the upper surface of the plastic handle 2, and the left end of which penetrates the left surface of the plastic handle 2. An L-shaped steel needle 13 is disposed within the L-shaped mounting cavity, and a needle tip 11 is provided at the left end of the L-shaped steel needle 13. The needle tip 11 is flat and spindle-shaped. The L-shaped steel needle 13 has a hollow structure, and an inlet hole penetrating the needle tip from front to back is provided in the middle of the needle tip. The inlet hole communicates with the hollow structure. An auxiliary [feature / equipment] is provided at the upper end of the plastic handle 2. The auxiliary cylinder 4 has a first circular hole at its bottom center. The upper end of the L-shaped steel needle 13 is located inside the first circular hole. The top center of the auxiliary cylinder 4 has a rubber soft plug mounting groove communicating with the first circular hole. A rubber soft plug 8 is provided on the rubber soft plug mounting groove. The lower end of the plastic handle 2 on the left side of the auxiliary cylinder 4 has a first finger placement groove 3. The right end of the auxiliary cylinder 4 has a second finger placement groove 9. The left side of the plastic handle 2 has a steel needle protective sleeve 1. The L-shaped steel needle 13 and the needle tip 11 on the left side of the plastic handle 2 are both located inside the steel needle protective sleeve 1.
[0025] This technical solution uses needles that combine dry and wet needle therapy. It can loosen and release soft tissues and also has the function of drug injection. This makes the loosening and drug injection more effective, reduces the frequency of treatment, and also reduces costs, thereby improving the performance of the needles.
[0026] In this technical solution, the needle 11 is flat and spindle-shaped, similar to an ancient spear. The tip of the needle is sharpened, which can improve the sharpness of the needle 11, enabling precise puncture and greatly reducing the risk of damage to soft tissues such as nerves and blood vessels.
[0027] The plastic handle 2 of this technical solution can be made by placing the prepared L-shaped steel needle 13 on a fixed mold and then molding the plastic handle 2 by injection molding.
[0028] For example, in some embodiments, the plastic handle 2 has a cylindrical structure. This makes it easier for doctors to operate the handle.
[0029] For example, in some embodiments, the left end of the plastic handle 2 is provided with a circle 14 that mates with the L-shaped steel needle 13, and the steel needle protective sleeve 1 is fitted onto the circle 14. This facilitates the installation of the steel needle protective sleeve 1.
[0030] For example, in some embodiments, a connecting belt 10 is provided on the auxiliary cylinder 4. The connecting belt 10 includes a first plastic ring 5, a plastic belt 6, and a second plastic ring 7 that are sequentially connected. The first plastic ring 5 is sleeved on the auxiliary cylinder 4, and the second plastic ring 7 is sleeved on the rubber soft plug 8. This can avoid the loss of the rubber soft plug and reduce the chance of contamination of the rubber soft plug 8, which is more conducive to single-person multi-site release injection therapy.
[0031] For example, in some embodiments, the rubber soft plug 8 includes a rubber soft plug column that fits with the rubber soft plug mounting groove. A connecting circular plate is provided on the rubber soft plug column. A socket column that fits with the second plastic ring 7 is provided on the connecting circular plate. A circular top plate is provided on the socket column. The diameter of the socket column is smaller than the diameters of the connecting circular plate and the circular top plate. The second plastic ring is sleeved on the socket column 7. That is, the front of the rubber soft plug 8 has a "dry" - shaped structure, and the second plastic ring 7 is sleeved on the socket column 7 at the depression at the upper end of the "dry" - shaped structure. This facilitates the connection between the rubber soft plug 8 and the connecting belt 10, avoids the loss of the rubber soft plug 8, and reduces the chance of contamination of the rubber soft plug 8, which is more conducive to single-person multi-site release injection therapy.
[0032] For example, in some embodiments, the steel needle protection sleeve 1 is a plastic soft sleeve. First anti-slip lines are provided on the outer wall of the steel needle protection sleeve 1. This facilitates the removal and installation of the steel needle protection sleeve 1, prevents the contamination of the needle 11, and can also prevent accidental injury.
[0033] For example, in some embodiments, the length from the leftmost end of the needle 11 to the rightmost end of the L - shaped steel needle 13 is 80 mm, the length from the leftmost end of the needle 11 to the left end face of the plastic handle 2 is 50 mm, and the distance from the lowermost end to the uppermost end of the L - shaped steel needle 13 is 12.5 mm. Of course, the specific size can be adjusted according to actual needs and is not limited to the dimensions in the preferred embodiments.
[0034] For example, in some embodiments, second anti-slip lines are provided in the first finger placement groove 3, and third anti-slip lines are provided in the second finger placement groove 9. The first finger placement groove 3 can be used for placing the thumb, and the second finger placement groove 9 can be used for placing the index finger. In this way, the holding force is stronger, it is better to exert force, and the effect of levering and releasing is better.
[0035] The applicable symptoms of this technical solution: myofascial pain syndrome; patients with mild cervical spondylosis and lumbar disc herniation; soft tissue diseases such as tendinitis, tennis elbow, scapulohumeral periarthritis, bursitis, golfer's elbow, and tenosynovitis.
[0036] The usage method of this technical solution:
[0037] For patients with myofascial pain syndrome, palpate the muscles around the pain with your bare hands to find the irritation points, and mark the irritation points with a marker pen;
[0038] Using iodine solution, disinfect repeatedly three times, with the irritation point as the center, and the disinfection area is 10cm in diameter.
[0039] After disinfection, remove the protective sheath 1 of the steel needle and manually insert the needle 11 into the subcutaneous tissue. Then, insert the needle, asking the patient if they experience any discomfort during the insertion process. Once the position is satisfactory, use your left hand to remove the rubber soft stopper 8, hold the syringe with your left hand, and inject an appropriate amount of local anesthetic. After the anesthesia is satisfactory, use your left hand to insert the rubber soft stopper 8 back in. Use a soft tissue release needle to first pry and loosen longitudinally 2-3 times, then pry and loosen transversely 2-3 times. After the prying and loosening are completed, hold the needle with your right hand to stabilize it, use your left hand to remove the rubber soft stopper 8, hold the syringe with your left hand, and inject an appropriate amount of a small amount of adhesion release agent or analgesic substance. Then, remove the release needle and use your left hand to insert the rubber soft stopper back in, avoiding contamination of the syringe connection. Cover with a sterile dressing.
[0040] In summary, this invention utilizes a needle that combines dry and wet acupuncture techniques, enabling the manipulation and release of soft tissues while also providing drug injection. This results in better manipulation and drug injection effects, fewer treatment sessions, and reduced costs, thereby improving the overall performance of the needle.
[0041] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
