Abstract
Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine medical device technology, specifically to a curved needle. Background Technology
[0002] Curved needles, sometimes called fascia needles, are a type of needle used in traditional Chinese medicine. They stimulate specific acupoints or fascia tissues to regulate the flow of qi and blood, relax muscles and promote blood circulation, thereby treating diseases. At the same time, curved needles can also loosen adhesions in soft tissues, relieve nerve and blood vessel compression, and restore their normal function.
[0003] The bending angle of the needle tip is small, the therapeutic area is limited, the needle body needs to be moved and the position needs to be changed constantly, which increases the patient's discomfort. The risk of complications such as bleeding and infection due to nerve or blood vessel damage is increased. Its function is relatively single and cannot assist other medical operations. Utility Model Content
[0004] This invention addresses the problems of the aforementioned bent-pull needles, such as limited bending angle of the needle tip, limited therapeutic area, the need for constant movement of the needle body to change position, increased patient discomfort, increased risk of complications such as bleeding and infection due to nerve or blood vessel damage, and limited functionality that cannot assist in other medical procedures.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a bent needle, including a needle handle, a needle body, and a needle tip. The needle handle is dark green for easy viewing over a long period of time. The needle body extends into the needle handle and is fixedly connected to the needle handle. The needle tip is bent with a flat inner side and a semi-circular outer side. A groove is provided on the needle body.
[0006] As an improvement, the needle handle is flat, with a smooth flat surface on the top surface and a surface with shallow grooves on the bottom surface.
[0007] As an improvement, the needle tip is bent and raised towards the lower side of the needle shank, and the needle tip is a blunt, smooth curved surface without a cutting edge.
[0008] As an improvement, the needle body is cylindrical, with a length of 140mm, a needle tip length of 20mm, a bending height of 12mm, a needle handle length of 120mm, and a needle body diameter of 2.5mm.
[0009] As an improvement, the groove is 110mm long and the distance between the groove and the needle shank is 18mm.
[0010] The advantages of this utility model are: 1. The long curved head design makes it flexible and easy to use. The needle can directly enter the spinal canal and the femoral head. It can be used to release the fascia around the cylindrical bone. It has the advantages of fewer needle entry points and a wide release area. The needle head has a unique design. It is sharp, bladeless, flat, and has a certain angle, which makes it less likely to damage nerves and blood vessels and ensures the safety of treatment.
[0011] 2. The groove is designed as a track for fixed-point introduction, which assists in the embedding of wires, deep drug delivery, and other instrument guidance, thereby improving the functionality of this utility model. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the structure of this utility model.
[0013] Figure 2 This is a top view of the present invention.
[0014] Figure 3 This is a side view of the present invention.
[0015] As shown in the figure: 1. Needle handle; 2. Needle body; 3. Needle tip; 4. Groove. Detailed Implementation
[0016] 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.
[0017] Combined with appendix Figure 1 , Figure 2 , Figure 3 A curved needle includes a needle handle 1, a needle body 2, and a needle tip 3. The needle body 2 extends into the needle handle 1 and is fixedly connected to the needle handle 1. The needle tip 3 is curved with a flat inner side and a semi-circular opposite side. A groove 4 is provided on the needle body 2.
[0018] It should be noted that the long curved head is flexible and easy to use. The needle body 2 can directly enter the spinal canal and the femoral head. It can be used to release the fascia around the cylindrical bone. It has the advantages of fewer needle entry points and a wide release area. The needle head 3 has a unique design. It is flat, without a sharp point or blade, and has a certain angle, which makes it less likely to damage nerves and blood vessels, ensuring the safety of treatment. The overall side of the needle body 2 is "J" shaped. The needle body 2 is thin and round, and has a concave groove on the front.
[0019] The needle handle 1 is flat, with a smooth flat surface on the top and bottom and four sides with shallow grooves on the bottom. The needle handle 1 is made of non-toxic plastic and stainless steel needle body 2, which is a low-cost, disposable bent needle.
[0020] The needle tip 3 is bent and raised towards the lower side of the needle handle 1, and the needle tip 3 is a blunt, smooth curved surface without a blade.
[0021] The needle body 2 is cylindrical, with a length of 140mm. The needle tip 3 has a length of 20mm and a bending height of 12mm. The needle handle 1 has a length of 120mm, and the needle body 2 has a diameter of 2.5mm.
[0022] The groove 4 is 110mm long, and the distance between the groove 4 and the needle handle 1 is 18mm.
[0023] The groove 4 is set as a track for fixed-point introduction, which assists in the embedding of wires, deep drug delivery, and other instrument guidance.
[0024] In the specific implementation of this utility model, the disinfection operation covers an area larger than the acupuncture site to ensure the cleanliness and sterility of the acupuncture area. Holding the needle handle, the needle tip is inserted into the human body at an appropriate angle and depth along the gap between the skin and fascia. After the acupuncture is in place, the doctor can gently lift, insert, twist, or swing the needle to stimulate the acupoint or fascia tissue. The groove can be used to guide the needle insertion or assist in the embedding of threads, deep drug delivery, or as a guide for other instruments.
[0025] 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.
