Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a fat repair transplant needle. Background Technology

[0002] Liposuction, also known as fat removal surgery or body sculpting, is a procedure that uses instruments inserted through small incisions in the skin to remove fat fragments from the subcutaneous fat layer. It is suitable for body contouring.

[0003] Currently, patients often experience unevenness after liposuction, requiring secondary repair. Because scar adhesions may form after the initial procedure, repair requires dissection and release combined with fat repositioning for correction. Commercially available liposuction cannulas often have a single injection port on one side with a bullet-shaped tip. Fat injection can only diffuse in one direction and lacks the function of loosening and expanding. When filling areas with depressions or tight skin adhesions, the high surface tension and limited space often make it difficult to inject fat. Moreover, the fat often shifts outside the area requiring repair or clumps together after injection, forming new bumps. Therefore, there is an urgent need for a specialized instrument that can simultaneously perform dissection, release, and fat injection. Utility Model Content

[0004] The purpose of this invention is to provide a fat repair and transplantation needle to solve the problems mentioned in the background art. Commercially available liposuction needles often have a single-sided injection port and a bullet-shaped tip. Fat injection and liposuction can only diffuse in one direction and do not have the function of loosening and expanding. When filling depressions or areas with tight skin adhesions with fat, the high surface tension and small space often make it difficult to inject fat. Moreover, the fat often shifts outside the area that needs repair or clumps together after injection to form new protrusions.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fat grafting needle, including a base, a needle body at one end of the base, a blade at one end of the needle body, an inner hole on the inner side of the needle body, and a fat injection hole on the outer side of the needle body.

[0006] Preferably, the base is tapered, and the outside of the base is provided with anti-slip protrusions.

[0007] Preferably, the grease injection holes are provided in a plurality of manner, and the plurality of grease injection holes are arranged in an alternating manner.

[0008] Preferably, one end of the plurality of grease injection holes is connected to one end of the inner hole.

[0009] Preferably, the blade is arranged in a straight shovel shape, and one end of the base is fixedly connected to a Luer interface.

[0010] Preferably, the needle body is 20cm in length and 2.5mm in diameter.

[0011] Preferably, the diameter of the grease injection hole is set to 1 mm.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] This invention comprises a base, a needle body, and a blade, forming a liposuction needle. The base connects to an external syringe containing fat via a Luer interface. The blade at one end of the needle body penetrates the skin. As the needle body reciprocates and advances through the tissue, the spatula-shaped blade helps to separate and expand the tissue. This loosening of dense scar adhesions allows for sufficient tissue expansion, creating a cavity beneath the surface. Fat is then injected through the external syringe, passing through the needle's inner hole and filling through multiple injection ports connected to the inner hole. The staggered distribution of these injection ports ensures the fat is evenly dispersed, correcting unevenness and preventing fat displacement or clumping into new bumps. Attached Figure Description

[0017] 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.

[0018] This utility model provides the following technical solution:

[0019] Example 1

[0020] Please see Figure 1 , Figure 2A fat grafting repair needle includes a base 1, a needle body 2 at one end of the base 1, a blade 3 at one end of the needle body 2, an inner hole 21 on the inner side of the needle body 2, and an injection port 22 on the outer side of the needle body 2.

[0021] The above technical solution involves a liposuction needle composed of a base 1, a needle body 2, and a blade 3. The base 1 is connected to an external syringe containing fat via a Luer interface 11. The blade 3 at one end of the needle body 2 is inserted into the skin. As the needle body 2 reciprocates and advances through the tissue, the spatula-shaped blade 3 helps to separate and expand the tissue. This loosening of dense scar adhesions allows for sufficient tissue expansion, creating a cavity beneath the surface. Fat is then injected through the external syringe containing fat, passing through the inner hole 21 of the needle body 2. The fat is then injected through injection holes 22 connected to the inner hole 21. Multiple injection holes 22, arranged in a staggered pattern, allow the fat to diffuse evenly outwards, correcting unevenness and preventing fat from shifting outside the repaired area or clumping together to form new bumps.

[0022] Specifically, the base 1 is cone-shaped, and the outside of the base 1 is provided with anti-slip protrusions.

[0023] The above technical solution features a conical base design, which helps provide a stable grip during surgery and allows doctors to adjust the angle and force during operation. The external anti-slip protrusions increase the friction when the doctor holds the base, preventing operational errors caused by hand slippage during surgery and improving the safety and accuracy of the surgery.

[0024] Specifically, multiple grease injection holes 22 are provided, and the multiple grease injection holes 22 are arranged in an alternating manner.

[0025] The above technical solutions can ensure that fat is evenly distributed in the target area during injection, avoiding local overfilling or underfilling.

[0026] Specifically, one end of each of the multiple grease injection holes 22 is connected to one end of the inner hole 21.

[0027] The above technical solution ensures that fat can be smoothly delivered from the syringe through the inner hole 21 into the fat injection hole 22 and evenly released at the required location.

[0028] Specifically, the blade 3 is designed with a straight shovel shape, and one end of the base 1 is fixedly connected to a Luer interface 11.

[0029] Through the above technical solution, the blade 3 is designed as a straight shovel shape. This shape helps to dissect and open up tissues during surgery, creating favorable conditions for the insertion of the needle 2 and the injection of fat. The Luer interface 11 facilitates connection with an external syringe containing fat.

[0030] Specifically, the length of needle body 2 is set to 20cm, and the tube diameter is set to 2.5mm.

[0031] With the above technical solution, the needle body 2 is set to a length of 20cm, which can meet the needs of most fat grafting surgeries, while the 2.5mm diameter ensures sufficient fat delivery and appropriate tissue penetration.

[0032] Specifically, the diameter of the grease injection hole 22 is set to 1mm.

[0033] With the above technical solution, the diameter of the fat injection hole 22 is designed to be 1mm, which helps to control the injection speed and fat particle size, and ensures that the fat is evenly distributed in the target area.

[0034] In use, the liposuction needle is composed of a base 1, a needle body 2, and a blade 3. The base 1 is connected to an external syringe containing fat via a Luer interface 11. The blade 3 at one end of the needle body 2 is inserted into the skin. As the needle body 2 moves forward and reciprocates through the tissue, the spatula-shaped blade 3 can dissect and expand the tissue. This reciprocating movement of the blade 3 loosens dense scar adhesions, allowing the tissue to expand and form a cavity below the surface. Fat is then injected through the external syringe containing fat, entering the needle body 2 through the inner hole 21. The fat is then injected through injection holes 22 connected to the inner hole 21. Since there are multiple injection holes 22 arranged in a staggered pattern, the fat is evenly diffused outwards through these holes, thus correcting unevenness and preventing fat from shifting outside the area to be repaired or clumping together to form new bumps.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
