Description

Technical Field

[0001] This utility model belongs to the field of acupuncture anesthesia needle fixation technology, specifically relating to an acupuncture anesthesia needle fixator. Background Technology

[0002] Acupuncture anesthesia, as a method of anesthesia with a long history and unique advantages, occupies an important position in the clinical treatment of traditional Chinese medicine. It stimulates specific acupoints on the human body, stimulates the flow of qi and blood in the meridians, and regulates the body's physiological functions, thereby achieving the effects of analgesia and anesthesia. It is widely used in many fields such as surgery and pain management. In acupuncture anesthesia, the acupuncture needle is the core tool for treatment. Its precise insertion and stable fixation play a crucial role in the therapeutic effect. Currently, various devices for fixing acupuncture needles exist on the market, such as the "Acupuncture Needle Fixer for Acupuncture Anesthesia, relating to the field of acupuncture anesthesia technology, disclosed in existing patent CN209848094U, comprising a detachable fixing strap and a fixing device disposed on the fixing strap; the fixing strap is used to fix the fixing device to the human body, the fixing device comprising a base plate, a column, an adjusting arm, and a spring clip." Such devices can, to a certain extent, meet basic fixation requirements, ensuring that the acupuncture needle maintains a relatively stable position after insertion into acupoints, so as to connect with devices such as electroacupuncture instruments to achieve auxiliary therapeutic functions such as electrical stimulation. However, existing acupuncture needle fixers still have shortcomings in practical use:

[0003] The angle of the needle clamp in existing acupuncture needle fixation devices is fixed. In clinical applications, due to differences in patient position, acupoint location, and treatment needs, the required fixation angle of the acupuncture needle often varies. However, the needle clamps of existing fixation devices are usually designed and manufactured according to a preset fixed angle, and cannot be adaptively rotated to adjust the angle according to different fixation needs. This means that in actual operation, when it is necessary to adjust the needle angle, the operator can only meet the needs by readjusting the position of the entire fixation device or replacing it with a fixation device of a different angle. This not only increases the complexity and time cost of the operation, but may also affect the insertion depth and position accuracy of the acupuncture needle due to repeated adjustments, thereby reducing the treatment effect. Therefore, this utility model proposes an acupuncture anesthesia needle fixation device. Utility Model Content

[0020] 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.

[0021] Example

[0022] Please see Figures 1 to 4 This embodiment of the present invention provides the following technical solution: an acupuncture anesthesia needle fixation device, comprising a base 1, a first strap 11 and a second strap 12 respectively disposed at both ends of the base 1, and a column 2 disposed at the top of the base 1, wherein the inner surface of the first strap 11 is provided with a Velcro A side, and the outer surface of the second strap 12 is provided with a matching Velcro B side, so that the first strap 11 and the second strap 12 can be subsequently glued together by Velcro, and also includes

[0023] The structure consists of a rod base 31 fixed to the top side of the column 2, a rotating rod 32 rotatably mounted at the front end of the rod base 31, an L-shaped clamp 4 fixed to the front end of the rotating rod 32, a needle clamping plate 5 movably mounted inside the L-shaped clamp 4, and a clamping structure 33 set on the top of the rod base 31. Both the L-shaped clamp 4 and the needle clamping plate 5 are made of insulating plastic. The rotatable rotating rod 32 allows the operator to adjust the angle of the L-shaped clamp 4 according to the actual needle clamping requirements, thus meeting different clamping needs. After adjustment, the clamping structure 33 is used to clamp and limit the position. The bottom surface of the base 1 has an arc-shaped groove 13. This design allows the bottom surface of the base 1 to better fit the patient's limb skin, making the fixator and the skin more closely contacted and effectively enhancing the stability of the fixation.

[0024] In this embodiment, preferably, the clamping structure 33 includes a threaded base rod 331 fixed to the top surface of the rod seat 31, a movable collar 332 movably sleeved on the surface of the threaded base rod 331, a limiting pressure plate 334 fixed to the right side surface of the movable collar 332, a clamping limiting pad 335 installed on the bottom surface of the limiting pressure plate 334 and clamping the rotating rod 32, and a threaded tightening ring 333 threaded on the surface of the threaded base rod 331 and located at the top of the movable collar 332. When the operator fully tightens the threaded tightening ring 333, the clamping limiting pad 335 can clamp against the rotating rod 32, thereby clamping and limiting the rotating rod 32 and ensuring the stability of the L-shaped clamp 4 during daily operation.

[0025] In this embodiment, preferably, the threaded tightening ring 333 is threadedly connected to the threaded base rod 331, and the surface of the threaded tightening ring 333 is provided with multiple integrated anti-slip protrusions, which can facilitate the operator to rotate and tighten the threaded tightening ring 333 in the future.

[0026] In this embodiment, preferably, a guide sleeve 336 is glued to the left side surface of the movable collar 332, and a guide rod 337 is glued to the top surface of the rod seat 31. The guide sleeve 336 is slidably sleeved on the surface of the guide rod 337, so that the movable collar 332 can be stably guided and achieve stable lifting and lowering without rotation.

[0027] In this embodiment, preferably, the bottom surface of the clamping and limiting pad 335 is arc-shaped, so that the clamping and limiting pad 335 can better fit with the rotating rod 32, increasing the contact area between the two. In addition, the bottom surface of the clamping and limiting pad 335 is provided with multiple strip-shaped anti-slip grooves, which can increase the anti-slip effect and ensure the clamping stability of the rotating rod 32.

[0028] In this embodiment, preferably, an inner rotating groove is provided inside the front end of the rod seat 31, and an inner rotating block is rotatably installed inside the inner rotating groove. The front end of the inner rotating block extends to the front surface of the rod seat 31 and is fixed to the rotating rod 32, so that the rotating rod 32 can rotate smoothly at the front end of the rod seat 31.

[0029] In this embodiment, preferably, the L-shaped clamp 4 has a rod groove 41 inside, and a pressing block 6 is movably installed in the rod groove 41. The top end of the pressing block 6 extends to the outer surface of the L-shaped clamp 4. A spring 42 is installed between the bottom end of the pressing block 6 and the inner wall of the rod groove 41. A side slider 44 is fixed to the side of the bottom end of the pressing block 6. A side slide 43 is opened through the inner surface of the L-shaped clamp 4 for the side slider 44 to pass through. The end of the side slider 44 passes through the side slide 43 to the inner side of the L-shaped clamp 4 and is fixed to the needle clamp plate 5. A silicone pad 51 is installed on the top surface of the needle clamp plate 5.

[0030] In this embodiment, preferably, a cylindrical groove is provided inside the bottom end of the pressing block 6, and the top end of the spring 42 is inserted into the cylindrical groove. The cylindrical groove can prevent the spring 42 from deviating and does not affect the normal compression of the spring 42.

[0031] In summary, when using this acupuncture needle fixator, first, place the bottom surface of the base 1 against the patient's limb skin. Then, turn the threaded tightening ring 333 counterclockwise to move it upwards. Next, lift the movable collar 332 so that the clamping and limiting pad 335 no longer clamps and limits the rotating rod 32. At this point, rotate the rotating rod 32 to adjust the L-shaped clamp 4 and the needle clamping plate 5 to a suitable clamping angle, ensuring that the tilt angle of the L-shaped clamp 4 and the needle clamping plate 5 matches the acupuncture needle inserted into the patient's skin. Then, tighten the threaded tightening ring 333 clockwise to clamp and fix the clamping and limiting pad 335 against the rotating rod 32, thus fixing the angle of the L-shaped clamp 4 and the needle clamping plate 5. Finally, press down the pressing block 6. This increases the space between the needle clamping plate 5 and the L-shaped clamping seat 4. Then, the base 1 is moved so that the tip of the acupuncture needle can enter between the L-shaped clamping seat 4 and the needle clamping plate 5. Then, the pressing block 6 is released, so that the spring 42 pushes the pressing block 6 back, and the needle clamping plate 5 with the silicone pad 51 rebounds. Finally, the acupuncture needle is clamped and fixed by the pressure of the silicone pad 51 and the L-shaped clamping seat 4. Then, the first strap 11 and the second strap 12 are tightened to fix the base 1. The use of the fixator is then completed, ensuring that the acupuncture needle can be stably clamped by the L-shaped clamping seat 4 and the needle clamping plate 5. Since the angle of the L-shaped clamping seat 4 and the needle clamping plate 5 has been rotated to match the insertion angle of the acupuncture needle, the clamping stability is higher and it will not affect the inserted acupuncture needle.

[0032] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
