Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a lens suspension scleral puncture and suture guiding device. Background Art

[0002] Lens suspension, scleral puncture and suture guidance instruments are important tools used in ophthalmic surgery, especially when dealing with lens dislocation or performing intraocular lens implantation. Lens dislocation may be caused by congenital, traumatic or other lesions that lead to abnormal development or rupture of the suspension ligament, resulting in imbalance or loss of the lens' suspension force, leading to lens position displacement. In order to treat such diseases, ophthalmologists need to use specific instruments to complete operations such as scleral puncture, intraocular lens suspension and suture guidance.

[0003] Traditional lens suspension surgery usually involves scleral suture fixation, which requires external fixation at the sclera and uses a scleral flap to bury the knot to avoid knot exposure. However, this method has problems such as the knot may rub and irritate local tissues, leading to inflammatory reactions, knot erosion, exposure, and even endophthalmitis due to scleral ulcers. Therefore, the design and improvement of ophthalmic instruments have been ongoing to improve the safety, accuracy and efficiency of surgery.

[0004] Currently, there is no instrument specifically designed for intraocular lens suspension. Most procedures use other needles that have been artificially bent. The needles are not long enough, so threading needs to be done in the anterior chamber with the assistance of intraocular forceps. Too much operation in the anterior chamber can easily lead to corneal endothelial damage, causing postoperative corneal edema and even corneal endothelial decompensation. Summary of the invention

[0005] The purpose of the present invention is to provide a lens suspension scleral puncture and suture guiding instrument to solve the technical problems raised in the above background technology.

[0007] Furthermore, the length of the handle is 13 cm.

[0008] Furthermore, the scleral puncture needle is composed of a solid hard tube made of metal with uniform thickness.

[0009] Furthermore, the diameter of the scleral puncture needle is 0.05 mm and the length is 2 mm.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0020] like Figures 1 to 5 As shown, the present invention provides a lens suspension scleral puncture and suture guiding instrument, including a handle 1, both ends of the handle 1 are conical in design, which is convenient for holding and prevents the instrument from slipping, and one end of the handle 1 is a holding end, and the holding end of the handle 1 is provided with a plurality of parallel grooves 2, and an array of parallel grooves 2 is added to the end of the handle 1 to be held to increase resistance and play an anti-slip role. A scleral puncture needle 3 is fixedly installed on the top of the holding end of the handle 1, and the top of the scleral puncture needle 3 is a needle tip structure, which can perform scleral puncture and enter the eye. A needle hole 4 is provided at the top of the scleral puncture needle 3 for passing a polypropylene suture and guiding the suture out of the eye. The scleral puncture needle 3 is curved in an arc shape at the part near the top. The present invention can be repeatedly disinfected, can improve surgical efficiency, reduce operations in the anterior chamber, thereby reducing corneal damage and postoperative inflammatory reactions, reducing surgical complications, and improving patient prognosis.

[0021] Specifically, the length of the handle 1 is 13 cm. The above arrangement can ensure that the doctor can easily hold the handle during the operation while maintaining sufficient flexibility for delicate operations. In addition, in ophthalmic surgery, especially when performing intraocular lens suspension, the surgical space is usually relatively limited. The above arrangement helps to ensure that the instrument can move flexibly in the small space in or around the eye without interfering with other surgical instruments or causing unnecessary damage. The appropriate length of the handle 1 also helps the doctor better control the instrument and ensure the accuracy of scleral puncture and suture guidance.

[0022] Specifically, the scleral puncture needle 3 is composed of a solid hard pipe made of metal with uniform thickness. Metal materials usually have high hardness and toughness, and can easily penetrate the scleral tissue to ensure the smooth progress of the operation. The solid hard pipe design with uniform thickness enables the scleral puncture needle 3 to maintain a stable shape during the puncture process, and is not easy to bend or break, thereby improving the accuracy and safety of the operation. Generally, metal materials have good durability and corrosion resistance, and can withstand repeated use and disinfection during the operation. Moreover, the surface of the scleral puncture needle 3 made of metal is smooth, and it is not easy to adhere to dirt or bacteria, which is convenient for cleaning and disinfection after the operation.

[0023] Specifically, the diameter of the scleral puncture needle 3 is 0.05 mm and the length is 2 mm. The smaller diameter can make the scleral puncture needle 3 less damaging to the eye tissue, which helps to reduce bleeding and inflammatory reactions during the operation. At the same time, the small puncture needle can be more accurately positioned on the sclera to ensure the accuracy of the puncture. The moderate length also allows the scleral puncture needle to easily enter the scleral tissue during the operation, while not being difficult to control due to being too long, and reduces the risk of the puncture needle accidentally injuring other intraocular structures.

[0024] Specifically, the scleral puncture needle 3 is bent in a 90-degree arc at a portion near the top. The arc-shaped design enables the scleral puncture needle 3 to more flexibly adapt to the curvature of the sclera during the puncture process, thereby making it easier to accurately locate the predetermined puncture point. The accurate puncture position is crucial for the subsequent guidance of sutures and the suspension of the intraocular lens, and helps to ensure the success rate of the operation.

[0025] More specifically, the scleral puncture needle 3 is curved at a portion 0.5 mm from the top. Through the above arrangement, it can be ensured that the scleral puncture needle 3 reaches an appropriate depth when penetrating the sclera. In this way, it will not be too shallow to cause the suture to be unable to be fixed, nor will it be too deep to damage other structures in the eye. The above design conforms to the principles of ergonomics, allowing doctors to hold and operate the instrument more comfortably during the operation. This helps to improve the accuracy and efficiency of the operation.

[0026] More specifically, each groove 2 is rectangular in shape. The rectangular groove 2 design increases the friction coefficient of the handle 1 surface, so that the doctor can control the instrument more stably when holding it, and can maintain a good grip even in a wet or slippery environment.

[0027] More specifically, each groove 2 is elliptical in shape. The shape of the elliptical groove 2 is more in line with the natural shape of human fingers, so that the doctor can reduce the tension and fatigue of the hand muscles when holding the handle for a long time. This design helps the doctor maintain a better hand feel and operational flexibility during the operation.

[0028] Working principle: When performing artificial lens suspension, the apparatus of the present invention is used, the handle 1 is held, and the scleral puncture needle 3 is inserted into the eye through the sclera puncture 2mm behind the corneal limbus, passes through the artificial lens loop, and passes out through the corneal incision on the opposite side. Then, a polypropylene thread is inserted through the needle hole 4 at the tip of the scleral puncture needle 3, and the suture is guided through the eye and out of the scleral puncture port to form the production of artificial lens suspension sutures. From the above-mentioned scleral puncture port 180° opposite to the corneal limbus, the apparatus of the present invention is used to insert the scleral puncture needle 3 into the eye through the sclera puncture, passes through the artificial lens loop, and passes out through the corneal incision. Finally, a polypropylene thread is inserted through the needle hole 4 at the tip of the scleral puncture needle 3, and the suture is guided through the eye and out of the scleral puncture port to form the production of artificial lens suspension sutures on the other side.
