Description

Technical Field

[0001] The present invention belongs to the field of pupil shaping, and specifically relates to an anchor hook assembly for pupil shaping. Background Art

[0002] In the field of ophthalmic surgery, pupil shaping surgery, especially pupil constriction surgery, occupies an indispensable and important position. As a key link in correcting abnormal pupil shapes, improving visual function, and performing ocular repair treatments, the surgical effect of pupil constriction surgery has a decisive impact on the postoperative visual recovery, ocular appearance, and normal operation of the overall ocular function of patients.

[0003] In the existing practice of pupil constriction surgery, microsurgical suture techniques are usually used for surgical treatment. However, this method has relatively high requirements for the proficiency of medical staff. When medical staff with lower proficiency perform surgical operations, problems such as inaccurate suturing and improper control of the tightness of the suture line often occur, thus greatly increasing the surgical time. In actual operation, specifically, when medical staff use microsurgical suture instruments, due to unskilled operation, it is difficult to accurately control the spacing and depth of the suture stitches, and repeated adjustments are required. This not only prolongs the surgical operation time but also increases the discomfort and potential risks of patients during the operation.

[0004] Therefore, those skilled in the art have proposed an anchor hook assembly for pupil shaping to solve the problems raised in the background art. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an anchor hook assembly for pupil shaping to solve the problems in the prior art that the microsurgical suture technique has relatively high requirements for the proficiency of medical staff, and when medical staff with lower proficiency perform surgical operations, problems such as inaccurate suturing and improper control of the tightness of the suture line often occur, thus greatly increasing the surgical time.

[0006] An anchor hook assembly for pupil shaping includes a connecting ring. A plurality of anchor hook parts are arranged on the outer circle of the connecting ring along the circumferential direction of the connecting ring. The anchor hook part includes a fixed end. One end of the fixed end is provided with two hooks, and one end of each of the two hooks is fixedly connected to one end of the fixed end. A plurality of barbs are fixedly connected to one side of the outer circle of the hook. The other end of the fixed end is fixedly connected to a tail end hook.

[0007] Preferably, the two hooks are symmetrically distributed on both sides of the corresponding fixed end.

[0008] Preferably, the inner cavity of the tail end hook is adapted to the side wall of the connecting ring.

[0009] Preferably, the materials of the hook, the fixed end, the tail end hook and the barb are all polymethyl methacrylate.

[0010] Preferably, the diameter of the connecting ring is 3-5 mm.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention replaces the microscopic suture technique means in the prior art. This design greatly reduces the dependence on the knotting skills of medical staff. Regardless of the operator's experience, the surgical process can be completed with relatively consistent standards, thus effectively shortening the surgical time. Due to the improvement of surgical efficiency, the exposure time of the patient's eye tissue to the external environment is correspondingly reduced. This not only reduces the infection risk caused by long-term exposure, but also reduces the surgical pressure and discomfort of the patient. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0018] As shown in the attached Figure 1 to the attached Figure 3 shown:

[0019] Example 1: The present invention provides an anchor hook assembly for pupil shaping, including a connecting ring 2. A plurality of anchor hook parts 1 are arranged on the outer ring of the connecting ring 2 and along the circumferential direction of the connecting ring 2. The anchor hook part 1 includes a fixed end 102. At one end of the fixed end 102, two hooks 101 are provided. One ends of the two hooks 101 are fixedly connected to one end of the fixed end 102. On one side of the outer ring of the hook 101, a plurality of barbs 104 are fixedly connected. At the other end of the fixed end 102, a tail end hook 103 is fixedly connected.

[0020] The two hooks 101 are symmetrically distributed on both sides of the corresponding fixed end 102.

[0021] The inner cavity of the tail-end hook 103 is adapted to the side wall of the connecting ring 2.

[0022] The materials of the hook 101, the fixed end 102, the tail-end hook 103 and the barb 104 are all polymethyl methacrylate.

[0023] The diameter of the connecting ring 2 is 3 - 5 mm.

[0024] As can be seen from the above, medical staff first determine the number of the anchor hook parts 1 needed according to the specific conditions of the patient's pupil and the surgical requirements. This number is usually adjusted according to the size and shape of the iris area to be reshaped. Subsequently, the medical staff use special surgical instruments to carefully insert the hook 101 in each anchor hook part 1 into the patient's iris tissue under the assistance of a microscope and establish a stable connection with the iris. After all the hooks 101 have completed the effective connection with the iris, the medical staff place the connecting ring 2 at the central position surrounded by several anchor hook parts 1, and then establish a fixed connection through the tail-end hook 103 arranged at the tail end of the anchor hook part 1 and the connecting ring 2, so as to form an integral tension structure, enabling unified tension control among the various anchor hook parts 1 through the connecting ring 2, and further achieving the purpose of adjusting and maintaining the pupil shape. The entire workflow does not require knotting operations inside the eye, simplifying the complex suture steps in traditional surgeries;

[0025] Beneficial effects:

[0026] First, due to the introduction of the connection structure between the connecting ring 2 and the tail-end hook 103 in the design, the knotting operation that originally needed to be manually completed by doctors inside the eye is cancelled, effectively reducing the high dependence on the operation skills of medical staff. Especially when facing relatively inexperienced operators, it can greatly shorten the operation time, thereby reducing the exposure duration of the patient's eye tissue during the operation and reducing the infection risk;

[0027] Second, through the unified tension structure formed by multiple anchor hook parts 1 and the connecting ring 2, the traction force acting on the iris can be more evenly distributed, avoiding problems such as pupil asymmetry or deformation caused by uneven tightness of manual knotting, and improving the naturalness and symmetry of the pupil shape after surgery;

[0028] Third, the overall structure design is simple, facilitating rapid installation and adjustment during the operation, and also being conducive to the removal operation after surgery, improving the overall efficiency and safety of the operation. Therefore, this solution not only solves the technical threshold and uncertainty brought by the high-difficulty knotting operation in the traditional method, but also further improves the success rate of the operation and the comfort of the patient.
