Description

Technical Field

[0001] This utility model relates to a novel floating needle, belonging to the field of medical needle technology. Background Technology

[0002] Floating needle therapy is short for floating needle therapy, and also for its specialized tool, the disposable floating needle. It is an improvement on wrist-ankle acupuncture. Floating needle therapy is an acupuncture therapy that uses disposable floating needles to perform sweeping manipulations in the superficial fascia layer (mainly subcutaneous loose connective tissue) of non-painful areas. It is characterized by being virtually painless, fast-acting, and having a wide range of indications.

[0003] Patent No. 201520373588.5 discloses a floating needle, including a needle base, a needle core, a flexible tube and its flexible tube seat and protective sleeve. The floating needle core is fixed to the head of the needle base and consists of a needle core body and a needle core tip. The head of the needle base is provided with a circular hole-shaped groove. The groove is provided with a positioning port. The positioning port includes a first point and an inlet and a second point distributed on both sides of the first point. The flexible tube seat is circular and can be inserted into the groove. The flexible tube seat is provided with a first protrusion and a second protrusion.

[0004] However, for some chronic pain conditions, floating needle therapy may require multiple treatments to achieve good results. For example, patients with chronic frozen shoulder may need 5-10 or even more floating needle therapy sessions. To improve the treatment effect, it is usually combined with drug injection. However, traditional injection devices simply push the drug to the vicinity of the fascia, and the drug often accumulates in clumps at the injection point, failing to diffuse evenly at the fascial level. This results in incomplete drug coverage in the affected fascial area and insufficient drug concentration in more severe areas, affecting the treatment effect. Excessively high local drug concentrations may also cause inflammatory reactions or tissue irritation symptoms. At the same time, there is a lack of mechanisms to promote effective drug diffusion in the fascial tissue. Especially for highly viscous drugs, diffusion in dense fascial tissue is extremely slow, making it difficult to quickly infiltrate the entire affected fascial area and prolonging the onset time of treatment. Utility Model Content

[0005] This invention provides a novel floating needle to solve the problem of uniform drug diffusion at the fascial level, improve the efficacy of drug therapy, ensure a balanced drug concentration in all parts of the diseased fascia, quickly form an effective therapeutic concentration field, and reduce adverse reactions caused by local drug accumulation. It can enhance the clinical efficacy of traditional floating needle, dry needle, wet needle, and fascial block therapy, and broaden its application scenarios.

[0006] This utility model provides a novel floating needle, which includes a protective sleeve, a tubing assembly, a needle core assembly, and an injection assembly. The tubing assembly includes a tubing seat and a tubing, and the tubing has a drug delivery hole. The needle core assembly includes a base and a steel needle. The tubing seat is connected to the base, and the steel needle passes through the tubing. The injection assembly includes a three-way connector and an injection tube. The three-way connector and the tubing are connected through the injection tube, and the injection tube is equipped with a flow stop clamp.

[0007] Preferably, the hose seat is fixedly connected to the hose, and the hose is provided with a plurality of drug delivery holes, which are arranged in a circumferential linear distribution on the hose.

[0008] Preferably, the steel needle is located at the top of the base and is fixedly connected to the base, and the steel needle penetrates the top of the hose.

[0009] Preferably, the base is provided with a first groove corresponding to the hose seat, and the bottom of the hose seat is located inside the first groove.

[0010] Preferably, the base is provided with multiple anti-slip strips, and the anti-slip strips are fixedly connected to the base.

[0011] Preferably, the anti-slip strip has multiple linearly distributed pits.

[0012] Preferably, a first needle-holding handle is provided on one side of the base, and the first needle-holding handle is fixedly connected to the base.

[0013] Preferably, the tubing seat is slidably connected to the first groove, and a second needle-holding handle is provided on one side of the tubing seat.

[0014] Preferably, the first needle holding handle and the second needle holding handle are located on the same side.

The second needle holding handle passes through the second groove and slides within the second groove. The second groove is provided with a buckle component corresponding to the second needle holding handle.

[0015] The beneficial effects of this utility model are:

[0016] This invention provides a novel floating needle with multiple circumferentially linearly distributed drug delivery holes on a flexible tube. During sweeping motions at the fascia level, the medication flows evenly from multiple directions, dispersing along the fascial plane, effectively preventing local drug accumulation and ensuring a balanced drug concentration throughout the affected fascia. This rapidly forms an effective therapeutic concentration field, significantly improving therapeutic efficacy. A three-way tube enables multi-path drug delivery, allowing for flexible injection of different medications based on the patient's symptoms during the sweeping motion, enhancing treatment flexibility and efficiency. A fixed anti-slip strip with anti-slip dots is attached to the base, and a first needle-holding handle is located on one side of the base. These designs allow doctors to more stably control the floating needle during insertion and sweeping movements, effectively preventing slippage. The sliding connection between the tubular seat and the base, along with the cooperation of the second needle-holding handle, allows the needle to move away from the patient during sweeping movements by gripping the base, moving the needle tip into the tubular tube. This effectively prevents the needle from scratching the patient's subcutaneous tissue, ensuring the safety of the sweeping movement and significantly reducing the occurrence of medical accidents. The limiting protrusion on the second needle-holding handle cooperates with the locking component in the second groove to achieve stable fixation of the needle after insertion into the subcutaneous tissue, effectively preventing shaking during sweeping movements. This makes the operation more convenient and safer, reducing the demands on the operator and minimizing risks during the procedure. Attached Figure Description

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] Example 1: This utility model provides a novel floating needle, which includes a protective sleeve 1, a tubing assembly 2, a needle core assembly 3, and an injection assembly 4. The tubing assembly 2 includes a tubing seat 21 and a tubing 22, which are fixedly connected. The tubing 22 has multiple drug delivery holes 221, which are arranged in a circumferential linear distribution on the tubing 22. The needle core assembly 3 includes a base 31 and a steel needle 32, which is fixedly connected to the top of the base 31. The base 31 has a first groove 311 corresponding to the tubing seat 21, and the bottom of the tubing seat 21 is located inside the first groove 311. The steel needle 32 penetrates the tubing 22 and extends to the outside of the tubing 22. The injection assembly 4 includes a three-way tube 41 and an injection tube 42, which are connected to the tubing 22 at the bottom through the injection tube 42. The injection tube 42 has a corresponding flow stop clip 43, and the two outer ends of the three-way tube 41 are respectively provided with a heparin cap 411 and an end cap 412.

[0025] The base 31 is provided with a fixedly connected anti-slip strip 312, and the anti-slip strip 312 is provided with anti-slip dots. The base 31 is provided with a first needle holding handle 313 on one side, and the first needle holding handle 313 is fixedly connected to the base 31.

[0026] Before use, the bottom of the tubing seat 21 is inserted into the first groove 311. The steel needle 32 penetrates the tubing 22 and extends to the outer top of the tubing 22. The protective sleeve 1 is fitted onto the outside of the tubing assembly 2. During use, the protective sleeve 1 is removed. Using the anti-slip strip 312 and the first needle handle 313 on the handheld base 31, the steel needle 32 and tubing 22 are inserted into the appropriate subcutaneous position of the patient. The steel needle 32 and tubing 22 are moved in a sweeping motion at the subcutaneous fascia level by the bottom of the handheld base 31 and the first needle handle 313. While performing the sweeping motion, medication is injected through the injection component 4 according to the patient's symptoms, such as lidocaine, hyaluronic acid, or thrombolytic injection. Liquids such as Zhengqing Fengtongning Injection are used to improve efficacy and shorten the treatment course. The injected drugs are delivered into the patient's body through the infusion port 221 on the tubing 22. Multiple infusion ports 221 can ensure that the drugs flow out from the infusion port 221 after reaching the fascia level and are evenly dispersed in multiple directions along the fascia plane, avoiding local drug accumulation and ensuring a balanced drug concentration in all parts of the diseased fascia, quickly forming an effective therapeutic concentration field and greatly improving the efficacy of drug treatment. During the insertion and sweeping movements, the anti-slip strip 312 on the base 31 can effectively prevent slippage. The three-way tube 41 can achieve multi-path drug delivery during the sweeping movement. When needle retention is required, the existing nursing tube sealing procedure can be referred to.

[0027] Compared with existing technologies, the multiple circumferentially distributed drug delivery holes 221 on the flexible tube 22 allow the drug to flow evenly from multiple directions during sweeping movements at the fascial level, dispersing it in multiple directions along the fascial plane. This effectively avoids local drug accumulation, ensures a balanced drug concentration throughout the affected fascia, and rapidly forms an effective therapeutic concentration field, significantly improving the efficacy of drug therapy. The injection component 4 includes a three-way tube 41 and an injection tube 42. The three-way tube 41 has a heparin cap 411 and an end cap 412 at its outer ends. This allows doctors to administer drugs through multiple pathways via the three-way tube 41, meaning that during sweeping movements, different drugs can be flexibly selected for injection based on the patient's symptoms, improving the flexibility and efficiency of treatment. The base 31 has a fixedly connected anti-slip strip 312 with anti-slip dots, and a first needle handle 313 is also located on one side of the base 31. These designs allow doctors to more stably control the floating needle during insertion and sweeping movements, effectively preventing slippage.

[0028] Example 2: In the above example, when the steel needle 32 of the floating needle is inserted into the patient's subcutaneous tissue and performs a sweeping motion, if the top of the steel needle 32 is exposed or not properly fixed, it can easily scratch the patient's subcutaneous tissue and cause unnecessary damage. Therefore, this application example optimizes the tubular assembly 2 and the needle core assembly 3 based on the above example.

[0029] In this embodiment, the bottom of the hose seat 21 is slidably connected between the inside of the first groove 311 and the inner wall of the first groove 311. The bottom of the hose seat 21 is provided with a sliding groove 212. The inner wall of the first groove 311 is provided with a fixed protrusion that is slidably connected to the sliding groove 212. The fixed protrusion is fixedly connected to the inner wall of the first groove 311. A second needle holder 211 is provided on one side of the hose seat 21.

[0030] When using the device, if the steel needle 32 and the flexible tube 22 are inserted into the patient's subcutaneous tissue and a sweeping motion is required, the medical staff should press one hand on the second needle handle 211 to fix the flexible tube assembly 2, and hold the base 31 with the other hand. The base 31 will drive the steel needle 32 to move away from the patient, so that the tip of the steel needle 32 moves into the flexible tube 22. This prevents the tip of the steel needle 32 from scratching the patient's subcutaneous tissue during the sweeping motion, thus ensuring the safety of the sweeping motion and reducing the occurrence of medical accidents.

[0031] Compared with existing technologies, the sliding connection between the bottom of the flexible tube seat 21 and the first groove 311 is achieved through the groove 212 and the fixed protrusion. This allows the steel needle 32 to move away from the patient by holding the base 31 during the sweeping motion, so that the tip of the steel needle 32 moves into the flexible tube 22. In this way, the tip of the steel needle 32 will not be exposed, thereby effectively preventing the risk of scratching the patient's subcutaneous tissue, ensuring the safety of the sweeping motion, significantly reducing the occurrence of medical accidents, and improving the safety and reliability of medical treatment.

[0032] Example 3: In the above examples, when the steel needle 32 is inserted into the subcutaneous tissue and performs a sweeping motion, it may shake due to unstable hand or improper operation, or even extend out of the soft tube, causing damage to the subcutaneous tissue. Therefore, this application example optimizes the soft tube assembly 2 and the needle core assembly 3 based on the above examples.

[0033] In this embodiment, the first needle-holding handle 313 and the second needle-holding handle 211 are located on the same side. The first needle-holding handle 313 is provided with a second groove 314 corresponding to the second needle-holding handle 211. The second needle-holding handle 211 passes through the top of the second groove 314 and slides up and down in the second groove 314. The inner walls on both sides of the second groove 314 are provided with buckle components. The second needle-holding handle 211 is provided with two limiting protrusions 2111 corresponding to the buckle components. The two limiting protrusions 2111 are located on both sides of the second needle-holding handle 211 and are staggered in height. The bottom of the tubular seat 21 is provided with a rotatably connected limiting plate 213. The sliding groove 212 is located on the limiting plate 213. The rotation range of the limiting plate 213 and the bottom of the second needle-holding handle 211 corresponds to the second groove 314.

[0034] During use, when the needle is inserted into the patient's subcutaneous tissue, the limiting protrusion 2111 at the top of the second needle handle 211 is fixed to the buckling assembly on one side of the second groove 314. When the steel needle 32 needs to be retracted into the soft tube 22 after being inserted into the patient's subcutaneous tissue, the second needle handle 211 is rotated, and the limiting plate 213 rotates synchronously around the soft tube seat 21, causing the limiting protrusion 2111 to separate from the buckling assembly. The steel needle 32 is moved away from the patient by the base 31. It is then fixed by the buckling assembly on the other side of the second groove 314 and the limiting protrusion 2111 at the bottom of the second needle handle 211, thereby preventing the steel needle 32 from shaking and extending out of the soft tube 22 during the sweeping motion, which could damage the subcutaneous tissue.

[0035] Compared with existing technologies, the steel needle 32 is stably fixed after being inserted subcutaneously by the engagement of the limiting protrusion 2111 on the second needle-holding handle 211 and the snap-fit ​​assembly in the second groove 314. This effectively prevents the steel needle 32 from shaking during the sweeping motion, improving its stability. The steel needle 32 can be fixed and released simply by rotating the second needle-holding handle 211. When it is necessary to retract the steel needle 32 into the tubing 22, simply rotate the second needle-holding handle 211 to separate the limiting protrusion 2111 from the snap-fit ​​assembly, and then the base 31 will move the steel needle 32. This makes the operation more convenient and safer, reduces the requirements for the operator, and minimizes the risks during operation.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
