Description
Technical Field
[0001] The utility model relates to the technical field of medicine, in particular to a novel dry and wet dual-purpose fascia release needle. Background Art
[0002] Myofascial pain syndrome (MPS) is a musculoskeletal disorder characterized by localized areas of tightness (called trigger points) within the skeletal muscle and fascia. The lifetime prevalence of MPS in the general population is as high as 85%, with disparities between men and women. MPS is often a chronic condition with a long course, leading to fibromyalgia, but can also present with acute episodes. Current treatments for MPS include medications (nonsteroidal anti-inflammatory drugs, tricyclic antidepressants, muscle relaxants, local anesthetics, botulinum toxin, etc.), wet needling (trigger point injections), dry needling (acupuncture, floating needle therapy, micro-needle therapy), myofascial release (direct and indirect release), and physical therapy (transcutaneous electrical nerve stimulation, interferential current therapy, electronic biofeedback, etc.). Wet and dry needling are widely used clinically due to their minimal invasiveness, ease of use, rapid effectiveness, and low cost, achieving satisfactory clinical results.
[0003] In the 1940s, Professor Travell first proposed the concept of dry needling, and later collaborated with Simons to formally write it into "Myofascial pain and dysfunction: The trigger point manual". Dry needling is relative to wet needling. Wet needling refers to a needle that uses a hollow steel needle to inject drugs, represented by ordinary syringes. It was first used to inject analgesics at trigger points to treat myofascial pain syndrome and achieved satisfactory results. Dry needling refers to needles that do not inject drugs, including hollow steel needles and solid needles. Solid needles are currently widely used in clinical practice. The main representatives of solid needles are filiform needles, plum blossom needles, floating needles and small needle knives. Among them, floating needles and small needle knives are the products of the combination of traditional acupuncture and Western basic medicine. They are widely used in clinical practice and have clear effects.
[0004] Currently, wet needling mainly uses ordinary syringes. Although it can inject drugs, it is difficult to effectively pry and loosen the tissues because the syringe needle is short and has no holding point, and its clinical application is limited. As for dry needling, the filiform needle is thinner and has a thin holding point, so it cannot be effectively pried. Although floating needles and small needle knives can effectively pry and loosen the tissues, they have no effect on drug injection.
[0005] Therefore, improvements must be made with respect to the above-mentioned defects. Utility Model Content

[0027] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.
[0028] Reference Figures 1 to 6 The utility model provides a new type of dry and wet dual-purpose fascia release needle, including a plastic handle, wherein the plastic handle includes a large cylinder 1, a small cylinder 10 and a first cone 11 integrally formed from back to front, the large cylinder 1, the small cylinder 10 and the first cone 11 are coaxial, and a rubber plug hole coaxial with the large cylinder 1 is provided on the rear end surface of the large cylinder 1, and a rubber plug 7 is provided on the rubber plug hole, the bottom diameter of the first cone 11, the diameter of the small cylinder 10 and the rubber plug hole are the same, and a hollow steel needle mounting hole coaxial with the large cylinder 1 is provided on the front end surface of the rubber plug hole, the hollow steel needle mounting hole penetrates to the front end of the first cone 11, and a hollow steel needle 9 is provided on the hollow steel needle mounting hole, the first cone 11 and the small cylinder 10 constitute a sleeve cylinder, and a plastic soft sleeve 3 is sleeved on the sleeve cylinder, and the plastic soft sleeve 3 is inside The top of the plastic sleeve is provided with a socket hole 13 that cooperates with the socket column, and the socket hole passes through the plastic soft sleeve 3 from front to back. The front end of the plastic soft sleeve 3 is provided with a second cone 14, and the front end of the second cone 14 is provided with a long strip 4 perpendicular to the plastic soft sleeve 3. The second cone 14 and the long strip 4 form a T-shaped structure. The front end of the plastic soft sleeve is provided with a hollow steel needle outer sleeve hose 8 that cooperates with the hollow steel needle 9. The plastic soft sleeve 3, the second cone 14, the long strip 4 and the hollow steel needle outer sleeve hose 8 are integrally processed and formed, and a plastic hard sleeve 5 is sleeved on the hollow steel needle outer sleeve hose 8. The upper and lower rear ends of the small cylinder 10 and the lower and rear ends of the small cylinder 10 are both provided with a long strip protrusion 2, and the two long strip protrusions 2 are symmetrically arranged up and down. The upper and lower rear ends of the plastic soft sleeve 3 and the lower and rear ends of the plastic soft sleeve 3 are both provided with a long slot 12 that cooperates with the long strip protrusion 2.
[0029] In this technical solution, the second cone 14 and the long strip 4 form a T-shaped structure, which makes the tape stick more firmly and not easy to fall off.
[0030] This technical solution utilizes a cylindrical plastic handle for smoother operation and more effective prying and loosening. The hollow steel needle 9 is hollow and capable of drug injection. A plastic soft cannula 3 reduces discomfort for patients during indwelling catheterization, while a long strip 4 facilitates secure fixation with adhesive tape. The end of the plastic soft cannula 3 can be connected to a syringe for drug injection or a rubber stopper 7 to reduce the risk of infection during indwelling catheterization. The rubber stopper 7 prevents drug leakage and reduces the risk of infection during indwelling catheterization. This product effectively pries and loosens fascia while also injecting medication to prevent fascial adhesions and aseptic inflammation, maximally alleviating the pain symptoms of patients with myofascial syndrome.
[0031] For example, in some embodiments, the front end of the hollow steel needle 9 is located in front of the hollow steel needle outer tube 8, and the front end of the plastic hard sleeve 5 is located in front of the hollow steel needle 9. The left and right rear ends of the plastic soft sleeve 3 are both provided with short slots 6 that mate with the elongated protrusion 2. The two short slots 6 are symmetrically arranged, and the difference in length between the long slot 12 and the short slot 6 is greater than or equal to the distance between the front end of the plastic hard sleeve 5 and the front end of the hollow steel needle outer tube 8. The length of the long slot 12 is twice the length of the short slot 6. The plastic soft sleeve 3 has two slots of different depths (symmetrically located), namely the long slot 12 and the short slot 6. When the long slot 12 is connected to the elongated protrusion 2 of the plastic handle, the needle tip is exposed. When the short slot 6 is connected to the elongated protrusion 2 of the plastic handle, the needle tip is concealed within the hollow steel needle outer tube 8, reducing the possibility of soft tissue damage during prying and loosening.
[0032] For example, in some embodiments, the cross-section of the strip 4 is square. The hollow steel needle 9 penetrates the strip 4 from front to back. This makes it easier to fix the exposed portion of the plastic soft cannula 3 and the rubber plug 7 on the skin using wide adhesive tape.
[0033] For example, in some embodiments, the rubber stopper 7 is a T-shaped rubber stopper, which facilitates the flexible use of the rubber stopper 7.
[0034] For example, in some embodiments, the plastic handle is provided with anti-slip threads on its surface. The plastic handle with anti-slip threads provides a stronger grip and a better prying and loosening effect.
[0035] For example, in some embodiments, the long strip protrusion 2 is integrally formed with the large cylinder 1, the small cylinder 10, and the first cone 11. This can simplify the production process and reduce the manufacturing cost.
[0036] Currently, there is no corresponding rubber stopper product. After drug injection, the tube is left in place and the soft plug is used for occlusion. On the one hand, it prevents drug leakage, and on the other hand, it can reduce the chance of infection when the tube is left in place.
[0037] This technical solution is mainly used for the following indications: myofascial pain syndrome; patients with mild cervical spondylosis and lumbar disc herniation; tendinitis, tennis elbow, frozen shoulder, bursitis, golfer's elbow, tenosynovitis and other soft tissue diseases. The method of use is as follows:
[0038] 1. For patients with myofascial pain syndrome, touch the muscles around the pain with bare hands to find the irritation point and mark the irritation point with a marker;
[0039] 2. Use iodine tincture to disinfect the area 10 cm in diameter three times with the irritation point as the center.
[0040] 3. After disinfection, remove the plastic hard cannula 5 and insert the needle tip into the subcutaneous tissue by hand or with the help of a catapult. Then, insert the needle. During the insertion process, ask the patient if there are any special discomforts. The needle should not be inserted too deeply. Observe that the hollow steel needle floats between the fascia and subcutaneous tissue layers, and the needle tip forms a bulge under the skin.
[0041] 4. After the position is satisfactory, pull out the long strip protrusion 2 on the plastic handle from the long slot 12 and insert it into the short slot 6, so that the hollow steel needle outer tube 8 covers the needle tip of the hollow steel needle 9 to avoid damaging the soft tissue when prying and loosening;
[0042] 5. Hold the needle steadily and pry and release evenly (for patients with a low pain threshold, the rubber stopper can be removed before prying and releasing, and a small amount of local anesthetic can be injected before prying and releasing). During the process, ask the patient if they have any special discomfort.
[0043] 6. After the prying and loosening is completed, pull out the rubber plug and inject a small amount of adhesion release agent;
[0044] 7. After the injection is completed, pull out the prying and releasing needle, leaving the hollow steel needle outer tube 8 in the body, and insert the rubber stopper 7 into the hollow steel needle outer tube 8 to prevent the drug from flowing out;
[0045] 8. Use wide adhesive tape to fix the exposed part of the plastic soft cannula 3 and the rubber plug on the skin and remove them after 5-8 hours.
[0046] In summary, this technical solution is mainly used in orthopedics and pain medicine, and aims to improve the pain caused by myofascial syndrome. "Dual-use wet and dry" means that the needle can be used alone to release the fascia to improve pain, or local anesthetics can be injected before release, or drugs can be injected locally after release to improve pain. In theory, the clinical effect is better. At present, the functions of needles in the treatment of myofascial pain syndrome are relatively simple, and there are no needles that combine dry needle therapy and wet needle therapy on the market. This technical solution organically combines dry needle therapy and wet needle therapy to use a new type of needle, which can meet the needs of both treatments with one puncture, reduce the frequency and cost of patient treatment, and increase the effect of treatment. In addition, this technical solution combines the tube-retention characteristics of the floating needle to increase the action time, the treatment time is longer, the treatment effect is better, and the chance of infection is reduced.
[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
