Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to an improved needle knife. Background Technology
[0002] Acupuncture knife is a new type of medical device that combines the characteristics of both needles and knives. It resembles a needle in shape, but its tip is a flat knife only 0.8mm in diameter; hence the name "small needle knife." Using specific acupuncture techniques from Traditional Chinese Medicine, it can directly reach the lesion, treating diseased tissue through meridian regulation and loosening. In essence, acupuncture knife medicine integrates the needle of Traditional Chinese Medicine acupuncture with the scalpel of Western surgery, combining the therapeutic effects of both to address the root cause, control the disease promptly, and restore health, thus resolving problems that are difficult to solve in traditional medicine.
[0003] Needle knife therapy is a closed release technique that falls between surgical and non-surgical methods. The procedure involves rapidly inserting a small needle knife into the lesion site after local anesthesia. Through techniques such as twisting, picking, pushing, and pulling, the adhered diseased tissue is quickly separated, blockages are cleared, blood and qi flow smoothly, scars are removed, muscles and bones are loosened, spasms and pain are relieved, thereby restoring function and achieving a cure. This therapy is minimally invasive, causes little pain, is inexpensive, quick, effective, and has a high cure rate.
[0004] Current needle knife instruments generally consist of three parts: the needle handle, the solid needle body, and the blade. The blade of traditional needle knives has a wedge-shaped or V-shaped cutting edge. The wedge-shaped blade has a small release area, requiring multiple points and vertical lifting and thrusting cuts in one area, resulting in many small incisions and poor decompression effect; the V-shaped blade has a sharp cutting edge, making it difficult to make sliding cuts in the fascial compartment, otherwise it will cause secondary iatrogenic injury. Utility Model Content
[0005] This utility model provides an improved needle knife with a double-peaked wavy blade, which has a large release area and a blunt cutting edge. The cutting area can be expanded by sliding, resulting in less damage to surrounding blood vessels and nerves, thereby reducing the number of incisions and achieving a good decompression effect.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0007] An improved needle knife includes a needle handle, a needle body, and a blade head connected in sequence. The blade head is formed by two U-shaped blade heads connected in one piece. The connecting wall between the two U-shaped blade heads is shorter than the non-connecting walls on both sides, forming a double-peak wavy profile. A blade edge is provided along the double-peak wavy profile, and the blade edge is rounded and blunt.
[0008] Furthermore, the blade head is thicker at the upper end and thinner at the lower end, with smooth, downward-converging bevels on both sides of the cutting edge.
[0009] Furthermore, the needle handle is thick at both ends and thin in the middle, with concave arc surfaces on both the front and back sides.
[0010] Furthermore, the concave arc surface is evenly covered with anti-slip textures.
[0011] Furthermore, the non-connecting arms on both sides of the cutter head are slightly opened outwards.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. The blade of this utility model has a double-peaked wave shape, a large loosening area, and a blunt cutting edge. It can expand the cutting area by sliding, which minimizes damage to surrounding blood vessels and nerves, thereby reducing the number of incisions and achieving good decompression effect.
[0014] 2. The needle handle of this utility model has a concave center and anti-slip texture, providing a strong grip and preventing it from slipping out of the hand during operation. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

It is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.
[0022] In the description of the embodiments of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0023] like Figure 1-2 As shown, an improved needle knife includes a needle handle 1, a needle body 2, and a blade head 3 connected in sequence. The needle handle 1 is thick at both ends and thin in the middle, with concave arc surfaces 7 on both the front and back sides, and anti-slip textures 8 evenly distributed on the concave arc surfaces 7. The blade head 3 is formed by two U-shaped blades connected in one piece, with the connecting wall 4 in the middle of the two U-shaped blades being shorter than the non-connecting walls 5 on both sides, forming a double-peaked wavy profile. A cutting edge is set along the double-peaked wavy profile, and the cutting edge is rounded and blunt.
[0024] like Figure 3 As shown, the cutter head 3 is thick at the top and thin at the bottom, and the two sides of the cutting edge are smooth inclined surfaces 6 that converge downwards.
[0025] Preferably, the non-connecting arms 5 on both sides of the cutter head 3 are slightly open outward.
[0026] Taking the treatment of calf swelling requiring needle knife therapy as an example, the procedure is as follows: The patient lies supine. First, the needle knife is disinfected. Three points are selected on the upper, middle, and lower sides of the most swollen area of the calf. Local infiltration anesthesia is performed using 2% lidocaine. After determining the lesion location and clarifying the anatomical structure of the area, iodine is applied locally, then removed with alcohol, and covered with a sterile drape. The needle knife incision line is aligned with the major blood vessels, nerves, and muscle fibers. The needle handle is held and inserted into the needle knife. The incision enters the interfascial layer. After feeling the fascia just within the double-peaked wavy incision, a sliding cut is made. After fully releasing and decompressing the pressure at the upper, middle, and lower points, the needle knife is pulled out with gauze. The incision is disinfected with povidone-iodine and covered with a sterile dressing. The procedure is complete.
[0027] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
