Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of sewing needle, concretely relates to a special needle for face lifting of doudou. BACKGROUND

[0002] Face lift (also known as face lifting surgery or face lifting surgery) is a plastic surgery aimed at improving facial contours by repositioning and tightening loose skin and soft tissue. This surgery can be performed on different facial areas, including the upper, middle and lower face, and the eyebrow area, customized according to individual needs and the degree of skin laxity. The main features of face lift include: (1) personalized adjustment; different parts can be selectively lifted according to the specific skin laxity of the beauty seeker, such as the forehead, the glabella, the eyelid, the cheek, the nasolabial fold, the mandibular line, etc.; (2) long-term effect; this surgery can restore the sagging skin and tissue to a younger position, and because it is a structural change, the effect usually lasts for a long time; (3) improve the facial proportion: by lifting the face, the proportion of the face can be reshaped, especially the central part, making the face look more harmonious and younger.

[0003] Face lift surgery is a relatively delicate plastic surgery. When using a sewing needle to suture the facial skin, the following problems exist: first, the needle tip of the medical sewing needle used is round or triangular, and the breakage is large when piercing the human skin tissue, and the facial skin has a certain toughness, so it takes a lot of effort to puncture and suture with ordinary medical sewing needles; second, the needle hole of the existing sewing needle is at the tail end, which is a post-eye sewing needle. For face lift surgery that requires high concealment, precision and delicate operation, the post-eye sewing needle is not easy to control, and the doctor may need more time and effort to ensure that the wire passes through the tissue correctly, which not only affects the efficiency of the operation, but also may affect the final effect; and the post-eye sewing needle may leave more obvious marks on the surface of the skin because the angle at which the wire enters the tissue is different from that of the needle tip, which may cause the suture point to be uneven, affecting the appearance quality after healing; moreover, the ordinary needle is a single-sided needle tip and cannot move in multiple directions under the skin, so it cannot achieve the purpose of concealed fixation under the skin. The sewing needle will leave a nest-shaped depression when it passes through the facial skin. In view of the above situation, how to improve the existing sewing needle to meet the needs of face lift surgery has become a technical problem to be solved. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a special needle for face lifting of doudou, solving the technical problem that the existing sewing needle cannot meet the special needs of face lift surgery.

The middle part of the needle body is provided with a needle hole, which is an oblong hole, and the needle hole is used to pass the suture.

[0006] Further, the needle body is an integrated structure composed of a flat part and two round rod parts, and the two round rod parts are connected to the two ends of the flat part.

[0007] Further, the upper side and the lower side of the middle part of the flat part are provided with two shuttle-shaped grooves, and the two shuttle-shaped grooves are arranged in correspondence with each other, the needle hole is located in the middle position of the flat part, and the needle hole penetrates through the two shuttle-shaped grooves.

[0008] Further, the edge of the shuttle-shaped groove has a reinforcing ridge.

[0009] Further, the outer periphery of the base surface part, the outer periphery of the round rod part and the outer periphery of the flat part are provided with depth scale lines, the distance between adjacent two depth scale lines is 5 cm, and the distance between the scale line of the outer periphery of the base surface part and the tip end part is 5 cm.

[0010] Compared with the prior art, the utility model has the beneficial effects that: (1) By arranging needle tips at both ends of the bent needle structure, the doctor can more flexibly use the bilateral needle tips to move in multiple directions between the subcutaneous soft tissues during the operation to achieve the purpose of invisible subcutaneous displacement lifting. (2) The special needle tip structure is designed in combination of circular arc shape and imitation triangle, so that the needle tip can enter the skin tissue with small trauma, and the design of cutting edge can effectively cut the skin and reduce the tearing of the skin; the round corner structure of the back ridge line helps to reduce the resistance during puncture, so that the needle tip can more easily penetrate the skin tissue, and the risk of breaking the needle body is also reduced. (3) The needle hole is arranged in the middle part of the needle body instead of the tail part, which can improve the operation precision during suturing, facilitate the control of the wire material passing through the tissue correctly, thereby improving the operation efficiency and the final effect, and the design of the shuttle-shaped groove makes the suture stay in the groove during threading, reducing the marks left by the wire material on the skin surface and promoting the appearance quality after healing. (4) The integrated structure consisting of a flat part and two round rod parts provides good clamping operation convenience and sufficient strength. In particular, the design of the reinforced ridge increases the strength at the needle hole and reduces the possibility of the needle breaking in deep tissue.

[0011] (5) Setting depth scale lines is very important for surgeries that require precise control of suture depth. It can help doctors more accurately grasp the insertion depth of the suture needle and ensure the safety and effectiveness of the surgery. Attached Figure Description
