Description

Technical Field

[0001] This utility model relates to the field of guide needle technology, and in particular to an orbital fat release internal fixation guide needle. Background Technology

[0002] Orbital fat release is a widely used surgical procedure for blepharoplasty (eyebag removal). Its core principle is to surgically release excess fat from the orbital septum and fix it to the separated infraorbital periosteum to repair loose tissue and remove eyebags. Simultaneously, orbital fat release can also fill in the lower eyelid crease, effectively improving tear trough depression and restoring a youthful appearance to the eyes. Due to its minimally invasive nature, high efficiency, and rapid recovery, this procedure has gained widespread clinical application and recognition in recent years.

[0003] In orbital fat repositioning surgery, internal fixation is a crucial step, determining the durability and stability of the surgical outcome. Internal fixation typically involves securing the transferred fat in its target location, ensuring it doesn't shift again. To achieve this, surgeons often use guide pins for auxiliary fixation. A guide pin is a thin, needle-like object inserted into the body to provide direction or positioning for subsequent surgical procedures. In orbital fat repositioning surgery, guide pins are primarily used to guide surgical instruments or implants to the correct positions, such as accurately guiding sutures to the fat fixation area.

[0004] Traditional guide pins have some limitations. First, the guide pin itself is relatively small, and the suture hole is correspondingly small, which requires doctors to spend more time and effort during the suture threading operation. Therefore, this application proposes an orbital fat release internal fixation guide pin to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a guide needle for orbital fat release and internal fixation, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an orbital fat release internal fixation guide needle, comprising a guide needle body, the guide needle body being arc-shaped, needle tips being provided at both ends of the guide needle body, two sets of scale lines being provided on the guide needle body, the scale lines being located near the needle tips, a suture hole being provided on the guide needle body, the suture hole being located within the range marked by the scale lines, an inlet being provided at the inner end of the suture hole near the guide body, and the side of the inlet away from the suture hole having an arc-shaped structure design.

[0007] Preferably, a mating groove is provided on the inner wall of the wire hole near the wire inlet, and an elastic plate is provided on the side of the wire inlet away from the mating groove. The end of the elastic plate near the wire hole extends into the mating groove and is adapted to the mating groove.

[0008] Preferably, the inner and outer sides of the guide needle body are provided with clamping surfaces, and the clamping surfaces adopt a planar structure design.

[0009] Preferably, the scale lines are accurate to the millimeter.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an orbital fat release internal fixation guide needle, including a guide needle body 1, which is arc-shaped and has needle tips at both ends. Two sets of scale lines 2 are provided on the guide needle body 1. Near the needle tips, the guide needle body 1 has a threading hole 3 located within the range marked by the scale lines 2. A suture inlet 5 is provided on the inner side of the threading hole 3 near the guide needle body. The side of the suture inlet 5 away from the threading hole 3 has an arc-shaped structure. During threading, the suture is looped around the guide needle body 1 and slid inside the body. When it reaches the suture inlet 5, the suture slides into the threading hole 3 from the inlet 5. The structural design of the suture inlet 5 makes the threading process smoother, effectively solving the problem of difficult threading with traditional guide needles and shortening the operation time.

[0022] A mating groove 6 is provided on the inner wall of the thread hole 3 near the inlet 5. An elastic plate 7 is provided on the side of the inlet 5 away from the mating groove 6. The end of the elastic plate 7 near the thread hole 3 extends into the mating groove 6 and is adapted to the mating groove 6. In the natural state, the outer wall of the elastic plate 7 abuts against the inner wall of the mating groove 6. The mating groove 6 and the elastic plate 7 fit tightly in the natural state to effectively prevent the suture from slipping out from the inlet 5, thereby ensuring the normal use of the device.

[0023] The inner and outer sides of the guide needle body 1 are provided with clamping surfaces 4. The clamping surfaces 4 adopt a planar structure design, which makes it easy for doctors to use the needle holder to hold the needle stably during surgery.

[0024] The scale line 2 is accurate to the millimeter, providing doctors with accurate measurement and positioning basis, which helps to accurately control the depth and position of sutures during surgery and ensure the surgical effect;

[0025] The elastic plate 7 and the guide needle body 1 are integrally molded and made of stainless steel, which ensures the strength and corrosion resistance of the guide needle, extends its service life, and ensures stability during the operation.

[0026] Working Principle: The device features planar clamping surfaces 4 on both the inner and outer sides of the guide needle body 1, facilitating stable clamping by the surgeon during operation. The arc-shaped design of the guide needle body 1 and the needle tips at both ends allow for more flexible movement between tissues during orbital fat release surgery, facilitating positioning and fixation, and improving surgical precision and efficiency. The millimeter-precision scale 2 provides the surgeon with accurate measurement and positioning data, helping to precisely control the suture depth and position during surgery and ensuring surgical outcomes. During suture threading, the suture is looped around the guide needle body 1 and slid inside. When it reaches the suture inlet 5, the suture slides into the threading hole 3. The structural design of the suture inlet 5 makes the threading process smoother, effectively solving the problem of difficult suture threading with traditional guide needles and shortening surgical time. Simultaneously, the groove 6 and elastic plate 7 fit tightly in their natural state, effectively preventing the suture from slipping out from the suture inlet 5, thus ensuring the normal operation of the device.
