Description

Technical Field

[0001] This utility model relates to an auxiliary device for intraocular lens suspension surgery, belonging to the field of intraocular lens suspension surgery technology. Background Technology

[0002] Intraocular lens suspension (IPL) is a complex ophthalmic surgery performed to address specific vision problems, primarily treating cataracts or other lens diseases. IPL involves using an artificial lens to suspend the natural lens behind the iris, replacing the damaged or diseased natural lens and restoring the patient's vision. This surgery is performed under a high-powered microscope, where the surgeon uses special sutures to attach the transparent artificial lens to its relatively normal physiological position within the eye.

[0003] Trauma, surgery, or congenital factors may prevent the implantation of an artificial lens into the lens capsule. These patients require intraocular suspension of an artificial lens to restore some visual function.

[0004] Currently, traditional methods require instruments such as syringe needles, sutures, and intraocular forceps to perform the procedure either inside or outside the eye. Because syringe needles are straight and lack handles, it's not easy to conveniently pass the intraocular lens haptic and perform suture relays. This requires a highly skilled surgeon and carries the risk of accidentally injuring intraocular tissues or misplaced sutures, causing harm to the patient or prolonging the surgery time and increasing its complexity.

[0031] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0032] like Figure 1-6 As shown, the artificial lens suspension surgical aid includes:

[0033] The handle 10 is fixedly connected to the connector 12 and the connector 13 at both ends, respectively. The connector 12 has a connecting rod 20 threaded inside, and the other end of the connecting rod 20 has an end 21. The connector 13 has a needle tube 30 fitted inside. The needle tube 30 has an arc-shaped structure and a through hole 33 for the suture to pass through.

[0034] The handle 10 has a square cross-section, and anti-slip grooves 11 are provided on both sides of the handle 10 for gripping. The connector 12 has an annular structure and is integrally formed with the handle 10. The connector 12 has a conical connecting rod 20 inside. The end of the connecting rod 20 is fixedly connected to the end 21, and the end 21 has a groove 22 for storing dye inside.

[0035] In this technical solution, the anti-slip groove 11 can improve the stability during the gripping process, and the connector 12 is set for the installation of the connecting rod 20. The connector 12 is used as a marking end to mark the puncture position. In use, the connecting rod 20 is threaded onto the connector 12, and the dye is applied to the inside of the groove 22 of the end 21. The dye is methylene blue. The suspension and fixing position is 2mm behind the corneal limbus. It is mainly used for positioning the needle insertion position during surgery. The dye can be applied to make intraoperative markings.

[0036] The connecting seat 13 is an annular structure and integrally formed with the end of the handle 10. The edge of the connecting seat 13 is provided with several evenly distributed notches 14. The outer surface of the connecting seat 13 is provided with a threaded groove 16. A threaded sleeve 15 is movably fitted onto the surface of the connecting seat 13, and the threaded sleeve 15 is connected to the connecting seat 13 through external threads. The diameter of the end of the connecting seat 13 away from the handle 10 is smaller than the diameter of the other end. The interior of the connecting seat 13 is movably inserted into one end of the needle tube 30. The threaded sleeve 15 is a frustum-shaped annular structure, and the smaller diameter end of the threaded sleeve 15 contacts the surface of the connecting seat 13.

[0037] In this technical solution, the connecting seat 13 is used as the operating end. After holding the handle 10, the needle tube 30 is stably punctured. The needle tube 30 is inserted into the connecting seat 13. The protrusion 31 and the notch 14 are used to position the needle tube 30, ensuring that the arc-shaped needle tube 30 will not deflect during puncture. The threaded sleeve 15 is put on the connecting seat 13. When tightened through the threaded groove 16, the threaded sleeve 15 squeezes the connecting seat 13, causing the connecting seat 13 at the notch 14 to deform and press the end of the needle tube 30, thus achieving stable fixation. The needle tube 30 is arc-shaped, which facilitates its passage through the intraocular lens haptic without causing severe deformation of the eyeball.

[0038] The needle tube 30 has several evenly distributed protrusions 31 at one end, and each protrusion 31 is fitted and connected to the inside of the notch 14; the needle tube 30 has a needle tip 32 at one end, and the end of the needle tube 30 near the needle tip 32 has a through hole 33 with an elongated structure.

[0039] In this technical solution, the end of the needle tube 30 is provided with a needle tip 32, which facilitates puncturing the sclera to enter the eye. A certain distance is provided from the tip to facilitate the insertion of various types of sutures. The diameter of the needle tube 30 is not greater than 25G, so as to avoid damage to the ciliary body tissue of the eyeball and eliminate the need for additional suturing of the puncture site.

[0040] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
