Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical device technology, specifically to a three-eighths arc lengthened suture needle suitable for children with thick abdominal wall hernia. Background Technology
[0002] Laparoscopic internal ring ligation is a classic surgical procedure for treating pediatric hernias. During the procedure, a traditional 2-0 needle-supported suture is inserted through the abdominal wall into the abdominal cavity from outside the body. The internal ring is then sutured within the abdominal cavity, and the suture exits through the abdominal wall afterward. Most children have thin abdominal walls, allowing for easy insertion and exit of the traditional 2-0 needle-supported suture under direct vision. However, with the increasing prevalence of childhood obesity, many children with hernias also have thickened abdominal walls. For children with thicker abdominal walls, the large arc of the traditional 2-0 needle-supported suture results in increased "bite depth," making both insertion and exit through the abdominal wall extremely difficult. Furthermore, the short "chord length" of the traditional 2-0 needle-supported suture leads to insufficient insertion and exit during insertion and exit.
[0003] However, existing 3 / 8 arc extended sutures suitable for children with thick abdominal wall hernias have some drawbacks in practical use: there is currently no extended version of the suture suitable for children with thick abdominal wall hernias, and the arc is also suitable for surgical operation. Traditional 2-0 needle-inlaid sutures are only suitable for children with thin abdominal walls, and not for children with thick abdominal walls, especially those with an abdominal wall thickness ≥2.5cm. This means that applying traditional 2-0 needle-inlaid sutures to children with thick abdominal walls will increase the difficulty and inconvenience of the operation, prolong the operation and anesthesia time, and indirectly increase the surgical risks.
[0004] To address this issue, we designed a three-eighths arc lengthened suture needle suitable for children with thick abdominal wall hernias. Utility Model Content
[0005] The purpose of this invention is to provide a three-eighths arc lengthened suture needle suitable for children with thick abdominal wall hernias, in order to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a three-eighths arc lengthened suture needle suitable for children with thick abdominal wall hernia, including a suture needle body, the suture needle body including a needle tip, an arc-shaped needle and a needle tail, the needle tip, the arc-shaped needle and the needle tail are connected in sequence, the arc-shaped needle is designed with a three-eighths arc, and the top of the needle tail is provided with a straight needle section.
[0007] Furthermore, a suture hole is provided at the end of the straight needle segment away from the curved needle, and a suture thread is provided on one side of the straight needle segment. The suture thread is detachably connected to the needle body through the suture hole.
[0008] Furthermore, the needle tip is smoothly connected to the arc-shaped needle.
[0009] Furthermore, the arc-shaped needle is smoothly connected to the needle tail.
[0010] Furthermore, the length of the arc-shaped needle is approximately 1 cm.
[0011] Furthermore, the length of the straight needle segment is 3cm.
[0012] Furthermore, the material of the suture needle body is medical-grade stainless steel.
[0013] Furthermore, the suture is made of polypropylene monofilament.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By optimizing the arc and length design of the suture needle, it is suitable for children with thick abdominal walls, and can be fast and efficient when the suture needle enters or exits through the abdominal wall.
[0016] 2. The suture curvature is more suitable for suturing the internal ring of children with hernias.
[0017] 3. Like the sutures currently used in clinical practice, this suture is itself a sterilized surgical instrument that can be used directly during the operation. Attached Figure Description

[0023] 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.
[0024] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: a three-eighths arc lengthened suture needle suitable for children with thick abdominal wall hernia, including a suture needle body 1, the suture needle body 1 including a needle tip 2, an arc needle 3 and a needle tail 4, the needle tip 2, the arc needle 3 and the needle tail 4 are connected in sequence, the arc needle 3 is designed with a three-eighths arc, and the top of the needle tail 4 is provided with a straight needle section 5.
[0025] In practice, during the insertion phase: the needle tip 2, with its sharpness and the penetrating power of the extended needle tail 4, quickly penetrates the thick abdominal wall and enters the abdominal cavity. The three-eighths arc reduces the contact area between the needle body 1 and the tissue, thus reducing resistance. During the suturing phase: the curved needle 3 completes the precise suturing of the internal ring in the abdominal cavity. The small arc design facilitates the adjustment of the suturing angle. During the exit phase: the extended straight needle section 5 of the needle tail 4 provides sufficient length to ensure that the needle body 1 can smoothly pierce through the opposite abdominal wall and complete the ligation.
[0026] See Figure 3 The straight needle section 5 has a suture hole 6 at the end away from the curved needle 3. A suture 7 is provided on one side of the straight needle section 5. The suture 7 is detachably connected to the needle body 1 through the suture hole 6. The needle tip 2 is smoothly connected to the curved needle 3, and the curved needle 3 is smoothly connected to the needle tail 4 to avoid deviation due to resistance during the operation and maintain overall strength and smooth operation.
[0027] See Figure 1 The arc-shaped needle 3 is about 1 cm long. The arc-shaped needle 3 performs the suturing operation of the inner ring opening, controlling the needle depth and suturing path. The arc-shaped needle 3 is about 1 cm long to ensure that the inner ring opening area is accurately covered during suturing. The straight needle section 5 is 3 cm long. The straight needle section 5 extends the total length of the suture needle body 1, which is convenient for laparoscopic instrument clamping operation. The increased total length ensures that the suture needle body 1 can penetrate the thick abdominal wall. The straight needle design makes it easy for the laparoscopic needle holder to hold it firmly and avoid slippage.
[0028] See Figure 1 The needle body 1 is made of medical-grade stainless steel. The high hardness and sharpness of medical-grade stainless steel ensures low resistance when penetrating the thick abdominal wall. Its corrosion resistance meets the requirements for surgical instrument sterilization, such as high temperature and high pressure, and chemical sterilization. Its biocompatibility is certified by ISO 10993 to avoid tissue rejection.
[0029] See Figure 1 The suture 7 is made of polypropylene monofilament. The surface of polypropylene monofilament is smooth, which reduces tissue drag damage. The 2-0 specification suture has a diameter of about 0.35mm, which can withstand the abdominal wall suturing tension and is not prone to causing inflammation. It is suitable for long-term implantation, such as hernia repair. It is easy to tie knots and the knots are stable. It is compatible with the suture needle body 1 for operation.
[0030] Working principle:
[0031] Insertion stage: The needle tip 2, with its sharpness and the penetrating power of the extended needle tail 4, quickly penetrates the thick abdominal wall and enters the abdominal cavity. The three-eighths arc reduces the contact area between the needle body 1 and the tissue, thus reducing resistance. Suturing stage: The curved needle 3 completes the precise suturing of the internal ring in the abdominal cavity. The small arc design facilitates the adjustment of the suturing angle. Exit stage: The extended straight needle section 5 of the needle tail 4 provides sufficient length to ensure that the needle body 1 can smoothly pierce through the opposite abdominal wall and complete the ligation.
