Description

Technical Field

[0001] This utility model relates to the field of plastic and cosmetic surgery equipment technology, specifically to a breast liposuction needle. Background Technology

[0002] Gynecomastia is a common condition characterized by abnormal proliferation of male breast tissue. For patients, gynecomastia not only affects appearance but can also cause psychological distress, leading to a growing demand for treatment.

[0003] Currently, male gynecomastia correction surgery typically combines vacuum aspiration with glandular excision. When the patient has significant glandular hyperplasia, additional incisions around the areola are necessary to remove excess glandular tissue. However, postoperative complications such as scar hyperplasia, pigmentation, and adhesions / depressions can occur, negatively impacting the patient's appearance. While some improvements have been made to existing techniques, such as changing the incision location and using more advanced liposuction equipment, the results remain unsatisfactory. To improve surgical outcomes and reduce postoperative complications, there is an urgent need for a novel medical device that can enhance surgical effectiveness while minimizing trauma. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a breast liposuction needle.

[0005] This utility model discloses a breast liposuction needle, including a needle body and a needle handle. The needle body has a hollow cylindrical structure, the front end of the needle body is a sharp needle head with an open design, and the rear end of the needle body is connected to the needle handle.

[0006] The needle body has multiple liposuction holes on its side wall, which are equidistantly staggered. Each liposuction hole is provided with barbs for cutting glandular tissue.

[0007] As a further improvement of this utility model, the sharp needle head is formed by beveled or inclined cut.

[0008] As a further improvement of this utility model, the liposuction hole is an elliptical liposuction hole extending along the axial direction of the needle body.

[0009] As a further improvement of this utility model, the angle between the barb and the side wall of the needle body is 30°.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings:

[0022] like Figure 1 As shown, a breast liposuction needle according to the present invention includes a needle body 1 and a needle handle 2. The needle body 1 has a hollow cylindrical structure, and the front end of the needle body is a sharp needle head 13 with an open design. The rear end of the needle body 1 is connected to the needle handle 2. The side wall of the needle body 1 has multiple liposuction holes 11, which are equidistantly staggered. Each liposuction hole 11 is provided with a barb 12 for cutting glandular tissue.

[0023] In this embodiment, the structure is simple and the operation is easy. By carefully designing the liposuction port 11 on the side wall of the needle body 1 and setting the barbs 12 at the liposuction port 11, a perfect combination of cutting and liposuction functions is cleverly achieved. In male gynecomastia correction surgery, the barbs 12 on the liposuction port 11 can efficiently cut glandular tissue while performing liposuction. This greatly reduces many complications caused by traditional areola incision surgery, such as scar hyperplasia, pigmentation, and tissue adhesion and depression, bringing better surgical results and postoperative experience to patients; at the same time, it improves surgical efficiency to a certain extent.

[0024] Specifically:

[0025] In the above embodiments, preferably, the sharp needle head 13 is formed by an angled or beveled cut, and the sharp needle head 13 is an open structure connected to the hollow cylindrical structure.

[0026] In the above embodiments, preferably, the liposuction hole 11 is an elliptical liposuction hole extending along the axial direction of the needle body 1.

[0027] In the above embodiments, preferably, the plurality of liposuction holes 11 are equidistantly staggered along the axial direction of the needle body 1.

[0028] In the above embodiments, preferably, the needle body 1 is a hollow cylindrical structure, the hollow interior of the needle body 1 forms a channel for fat to flow, and the multiple liposuction holes 11 are all connected to the hollow interior of the needle body 1.

[0029] In the above embodiments, preferably, the outer diameter of the needle body 1 is 3-4 mm, and the length of the needle body 1 is 35 cm.

[0030] In the above embodiments, preferably, the angle between the barb portion 12 and the side wall of the needle body 1 is 30°.

[0031] In the above embodiment, preferably, the barb portion 12 is an elliptical barb; the elliptical barb is provided at the end of the liposuction hole 11 away from the needle handle 2 and extends toward the needle handle 2.

[0032] Specifically, the oval barb has a smooth, curved edge, with one end connected to the edge of the liposuction port 11 away from the needle handle 2, and the other end extending towards the needle handle 2. During the surgical procedure, as the liposuction needle moves, the oval barb utilizes its shape to scrape glandular tissue from the surrounding tissue. Because the barb extends towards the needle handle, the scraped tissue can follow the surface of the barb, pass through the liposuction port 11, and enter the hollow part of the needle body 1, completing the tissue aspiration process.

[0033] In another embodiment, the barb portion 12 is a U-shaped barb; the U-shaped barb is provided at the end of the liposuction hole 11 away from the needle handle 2, and the open end of the U-shaped barb extends toward the needle handle 2.

[0034] Specifically, the U-shaped barb is U-shaped, comprising a curved portion and two parallel sides. The U-shaped barb extends from the liposuction port 11 of the needle body 1, with its opening facing the needle handle 2. During surgical procedures, when the liposuction needle is manipulated within the breast tissue, such as by pulling back or rotating, the curved portion of the U-shaped barb effectively cuts the glandular tissue. Because its opening faces the needle handle 2, the cut tissue is carried by the curved portion of the barb and, guided by the barb, enters the interior of the needle body 1 through the liposuction port 11, thereby achieving tissue collection and removal.

[0035] How to use this embodiment:

[0036] 1) Determine the appropriate insertion position based on the specific condition of the patient's breast hypertrophy;

[0037] 2) Align the tip of needle 1 with the selected location and carefully insert it into the breast tissue;

[0038] 3) After the needle body 1 is inserted to an appropriate depth, slowly move and rotate the needle body 1 by holding the needle handle 2 so that the liposuction hole 11 on the side wall of the needle body 1 fully contacts the target gland tissue.

[0039] 4) During the movement and rotation, the barbs 12 (U-shaped barbs or oval barbs) at the liposuction port 11 begin to perform a cutting action, cutting off the glandular tissue;

[0040] 5) As the needle body 1 continues to operate, the cut glandular tissue, guided by the barb part 12, enters the hollow cylindrical structure of the needle body 1 through the liposuction hole 11.

[0041] 6) Connect the appropriate liposuction equipment and start the equipment to perform liposuction, so that the cut glandular tissue is continuously sucked out of the body.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
