[0035] The spacing between each graduation of needle scale 4 is 10mm. The width of needle scale 4 is 0.2mm.

[0036] The needle side hole 3 has an elliptical structure, and the number of multi-side holes in the needle side hole 3 is between 2 and 30.

[0037] The needle tip 2 is covered with a needle cap 5. The needle tip cover 1 is provided with anti-slip texture 6.

[0038] Working principle of the round-tipped multi-hole release and filling needle: In plastic and cosmetic procedures, this type of round-tipped multi-hole release and filling needle is used for skin release and filling operations. First, the end of the needle 2 is set with a round head 21. This design can reduce damage to skin tissue and allows for gentler skin handling during release operations, reducing the risk of damage to existing tissue.

[0039] The needle 2 has needle side holes 3, and the number of needle side holes 3 is between 2 and 30. The design of these side holes allows the filler to be evenly distributed into the skin tissue through the side holes during the filling operation. At the same time, the structural design of the side holes ensures that the original tissue is not damaged during the operation, thus improving the safety and effectiveness of the operation.

[0040] The needle tip graduations 4 on the needle tip 2 are an important feature of this needle tip 2. Each graduation is 10mm, making it easy to control the insertion depth. Operators can accurately determine the depth of needle tip 2 entering the skin according to specific operational needs, thereby improving the precision and safety of the operation.

[0041] The diameter of the needle 2 with a round head and a single-sided hole ranges from 0.1mm to 0.3mm, including needles with a round head and a single-sided hole of 0.3mm; the diameter of the single-sided hole ranges from 0.1mm to 0.3mm; and the length of the needle 2 with a round head and a single-sided hole ranges from 0.5cm to 15cm.

[0042] The needle 2 has a round head and multiple side holes with a diameter ranging from 0.1mm to 12mm, and the diameter of the multiple side holes ranges from 0.1mm to 0.8mm. The length of the needle 2 with a round head and multiple side holes ranges from 1.0cm to 30cm to accommodate different operating locations and needs. Each graduation on the needle scale 4 is 10mm apart and 0.2mm wide; the clear scale markings help operators accurately judge the needle insertion depth.

[0043] The needle side hole 3 has an elliptical structure, and the number of multiple side holes in the needle side hole 3 can be between 2 and 30. This design increases the uniformity of the filling material distribution and the flexibility of operation.

[0044] The needle 2 is covered with a needle cap 5, which protects the needle 2 from contamination and damage when not in use. The anti-slip texture 6 on the needle cap 1 helps the operator to better grip the needle cap 1 during operation, prevents slippage, and improves operational stability.

[0045] Workflow of round-headed multi-sided hole loosening and filling needle:

[0046] Preparation: Select the appropriate needle 2: Based on the specific needs of plastic surgery and beauty, select a needle 2 with a round head and a single-sided hole with a diameter range of 0.1mm to 0.3mm, including needles with a round head and a single-sided hole of 0.3mm; the diameter of the single-sided hole ranges from 0.1mm to 0.3mm; and the length of the needle 2 with a round head and a single-sided hole ranges from 0.5cm to 15cm.

[0047] The diameter of the needle 2 with a round head and multiple side holes ranges from 0.1mm to 12mm, the diameter of the multiple side holes ranges from 0.1mm to 0.8mm, and the length of the needle 2 with a round head and multiple side holes ranges from 1.0cm to 30cm.

[0048] Check needle 2: Ensure that needle 2 is undamaged and undeformed, the side hole 3 of the needle is unobstructed, and the scale line 4 of the needle is clearly visible.

[0049] Disinfection: The needle 2 is subjected to strict disinfection to ensure the safety of the operation.

[0050] Install needle 2: Install the sterilized needle 2 onto the needle cap 1, ensuring a secure installation.

[0051] Selecting the injection site: Based on the plastic surgery and cosmetic plan, determine the areas of skin that need to be loosened and filled.

[0052] Holding the needle cap 1: The operator holds the needle cap 1 with his hand, using the anti-slip texture 6 on the needle cap 1 to increase the stability of the grip and prevent it from slipping.

[0053] Needle insertion procedure: Gently touch the rounded head 21 of needle 2 to the skin surface, and then gradually advance needle 2. Refer to the scale lines on needle 2, each scale is 10mm, and accurately control the depth to which needle 2 enters the skin according to the required insertion depth.

[0054] Release procedure: Once the needle 2 reaches the appropriate depth, gently move the needle 2 and use the round head 21 to release the skin tissue. Be careful to be gentle and avoid causing excessive damage to the original tissue.

[0055] Filling procedure: If filling is required, the filler is injected into the skin tissue through the needle side hole 3. Because the needle side hole 3 is an elliptical structure and does not damage the original tissue, the filler can be distributed relatively evenly within the skin.

[0056] Observation and adjustment: During the procedure, observe the skin's reaction and the distribution of the filler at any time, and make adjustments as needed.

[0057] Remove needle 2: After completing the loosening and filling operation, slowly remove needle 2 from the skin.

[0058] Cleaning and handling: After the operation, properly dispose of the used needle 2 to avoid cross-infection. At the same time, clean and care for the operation site.

[0059] Example 2: A round-headed multi-sided hole loosening and filling needle. In this example, the needle 2 has multiple needle side holes 3. A round-headed multi-sided hole loosening and filling needle was selected. The needle sleeve 1 is tightly connected to the needle 2, and the end of the needle 2 is a round head 21, which can reduce damage to the tissue. The needle 2 has multiple needle side holes 3, with the number of needle side holes ranging from 2 to 30. During the operation, it can effectively loosen the soft tissue and inject the filling material evenly. The needle scale 4 on the needle 2 has 10mm graduations, allowing the doctor to precisely control the needle insertion depth as needed. During the operation, the doctor inserts the needle into the lesion site. The multi-sided hole design allows the filling material to be distributed more evenly in the tissue, achieving a good therapeutic effect.

[0060] Example 3: In this example, the diameter of the unilateral hole 3 on the needle 2 is 0.3 mm. The needle cap 1 also serves a protective and fixing function, and the rounded head 21 at the end of the needle 2 facilitates smooth entry into the tissue. The 0.3 mm diameter of the unilateral hole 3 on the needle 2 allows for more precise control of the injection location and dosage of the filling material, avoiding unnecessary impact on surrounding normal tissue. The needle graduations 4 on the needle 2 allow the doctor to accurately insert the needle to the predetermined depth. During the surgery, the doctor successfully released and filled the tissue around the compressed nerve using the precision of the unilateral hole needle, relieving the patient's symptoms and improving the success rate of the surgery.

[0061] Example 4: A round-headed, multi-sided, porous loosening and filling needle, comprising a needle sleeve 1. The needle sleeve 1 is made of medical-grade rubber material with a Shore hardness of A60-A80, possessing good elasticity and flexibility, and can tightly fit onto the needle 2, providing protection and fixation. The needle sleeve 1 features a finely distributed anti-slip texture 6 in a mesh pattern, with a depth of 0.1mm-0.2mm, increasing the friction between the finger and the needle sleeve 1, making operation more stable and safer.

[0062] The needle sheath 1 is equipped with a needle 2, which is made of high-strength stainless steel, specifically 316L stainless steel, exhibiting excellent corrosion resistance and wear resistance. The needle 2 has a round head with a single-sided hole, and its diameter ranges from 0.1mm to 0.3mm, including needles with a 0.3mm round head and single-sided hole. The diameter of the single-sided hole ranges from 0.1mm to 0.3mm, and the length of the needle 2 with a round head and single-sided hole ranges from 0.5cm to 15cm.

[0063] The needle 2 has a rounded tip with multiple side holes, and the needle diameter ranges from 0.1mm to 12mm. The diameter of the multiple side holes ranges from 0.1mm to 0.8mm, and the length ranges from 1.0cm to 30cm. The end of the needle 2 is equipped with a rounded head 21, which is finely polished with a surface roughness Ra value of less than 0.2μm, resulting in a smooth and rounded appearance that minimizes tissue damage. The curvature of the rounded head 21 is ergonomically designed to facilitate smoother insertion into the skin and reduce resistance.

[0064] The needle tip 2 has a side hole 3, which is elliptical in shape with a major axis to minor axis ratio of 2:1. The number of side holes 3 ranges from 2 to 30, and when multiple side holes are provided, the spacing between them is 5mm-10mm. The edges of the side holes are specially treated to be rounded and smooth, avoiding scratches and damage to surrounding tissues during operation.

[0065] The number of side holes 3 on the needle tip is between 2 and 30. The needle tip 2 is equipped with needle tip graduations 4, each graduation being 10mm, with a 10mm gap between the graduations and a width of 0.2mm. The graduations are made using high-precision laser engraving technology, with a depth of 0.05mm-0.1mm, making them clear and easy to accurately control the needle insertion depth.

[0066] The diameter of the needle 2 with a round head and a single-sided hole ranges from 0.1mm to 0.3mm, including needles with a round head and a single-sided hole of 0.3mm; the diameter of the single-sided hole ranges from 0.1mm to 0.3mm; and the length of the needle 2 with a round head and a single-sided hole ranges from 0.5cm to 15cm.

[0067] The diameter of the needle 2 with a round head and multiple side holes ranges from 0.1mm to 12mm, the diameter of the multiple side holes ranges from 0.1mm to 0.8mm, and the length of the needle 2 with a round head and multiple side holes ranges from 1.0cm to 30cm.

[0068] The needle tip 2 is covered by a needle cap 5, which is made of transparent plastic material, specifically polycarbonate, offering good transparency and impact resistance. Inside the needle cap 5 is a cushioning pad made of silicone material with a Shore A20-A30 hardness, which reduces vibration and impact during transportation and storage, protecting the integrity of the needle tip.

[0069] In plastic and cosmetic procedures, this round-tipped, multi-hole release and filling needle is used for skin release and filling operations. First, the tip of the needle 2 is designed with a round head 21. This design reduces damage to skin tissue, allowing for gentler skin handling during release operations and minimizing the risk of damaging existing tissue. During filling operations, filler material is evenly injected into the skin tissue through the needle's side holes 3, achieving cosmetic and restorative effects. The needle's graduation lines 4 help operators accurately control the needle insertion depth, ensuring the safety and effectiveness of the procedure. During insertion, the appropriate needle length and side hole diameter are selected according to different operating sites and needs. The needle is inserted into the skin in the predetermined direction, and the insertion depth is controlled by observing the needle's graduation lines 4 to achieve the desired treatment effect.
