1 TARIFF NITI WIRE CHOPPER DESIGN Technical Area 5 This invention is the basis for phacoemulsification, which is currently used in cataract surgery. by replacing the choppers in the method, the damaged natural eye lens Made from NiTi alloy, which minimizes the risks that may occur during decomposition. It relates to the chopper in the form of a ring. 10 Previous Technique Cataracts are the wear and tear of the eye lens caused by environmental or natural factors. It is known as a disease resulting from the blurring or clouding of the eye. Eye 15 This growth in the lens can cause vision loss, headaches, and various other health problems. This is the reason. Different surgical methods and techniques have been used in cataract treatment from the past to the present. It has been used, one of these methods being the one widely preferred today is 20 It is a "phacoemulsification" technique. In this technique, the damaged eye lens is broken down into small pieces using ultrasound waves. It is based on the principle of separation and extraction. The method consists of 2 stages; in the first stage... The nucleus is cut and absorbed from the capsule sac, and then the second stage; the remaining cortex 25 The fragments are removed from the capsular bag. Suction of the nucleus usually removes the nucleus. energy to emulsify and absorb the resulting nuclear particles from the eye This is done via phacoemulsification, using a phaco-ultrasonic device. The ultrasound procedure used in this technique analyzes cataracts of varying sizes and hardness. It is insufficient for breaking down, in this case the lenses are used in a 30-inch machine called a chopper. The pieces are manually broken down into smaller parts using tools, and then ultrasonic fragmentation is used. This makes the job easier by allowing the lens particles to be absorbed more easily. At this stage... There are many chopper designs, but the current invention is a new attachment and It offers an approach. 2 Because surgeons use choppers manually, the objects under the lens... Damage to the delicate structure called a zonule, which is supported by delicate fibers. There are risks. Because the pressure applied to the lens can damage the zonule underneath. It requires dexterity and precision. Different types of choppers have been designed so far. These designs, in terms of their lens... Although they try to minimize the applied pressure, they are of a similar form and structure. Because of this, dependence on the surgeon's skill and ability is still quite high. It is. The chopper designed in utility model number CN203790133U has two ends. It has been observed that it has an oval shape at one end and is capable of injecting water. 10 Patent number CN211460815U describes an oval-shaped chopper design, however... Although the designed structure has mobility, it does not exhibit elasticity. It has been observed that the risk of damage to the zonule structure persists. Patent number BRPI1002828A2 describes oval-shaped wires as chopper cutters. However, the wires used are made of stainless steel, and the wires... It breaks down the defective structure on the lens by squeezing it without opening a cutting edge, and this It also carries the risk of damaging surrounding tissues. The elastic chopper designed in the current patent study uses an innovative approach to 20 It comes into contact with both elastic and cutting edges. Purpose of the Invention The aim of the invention is to minimize chopper-related risks in cataract surgery. The aim is to prevent and mitigate potential damage. In this invention, the superstructure of NiTi alloy is used. The aim was to create a practical chopper design by taking advantage of its elasticity properties. This invention offers an easier-to-use alternative to the choppers currently in use. By providing this, it reduces the difficulties of the surgery, resulting in a shorter and less risky procedure. The aim is to break down the cataract in this way. 30 3 Explanation of the Figures Figure 1: Oval-tipped NiTi chopper design Figure 2: Basket-style NiTi chopper design Explanation of References in Figures 5 101a: Oval shaped cutting insert 101b: Elastic state of the oval-shaped cutting edge 101c: Elastic state of the oval-shaped cutting edge. 102: Body 201: Basket-shaped cutting edge 10 Description of the Invention Today, phacoemulsification is a widely used technique in cataract treatment. This technique involves addressing the distortions that occur in the lens of the eye. The resulting damage, called cataract, can be removed with the help of a cutting tool. breaking it down and removing these pieces with the help of a vacuum It includes, moreover, an artificial lens to replace the lens that has been removed by dismantling. The surgery is completed by inserting the device. At this stage, the existing invention design and mechanics are considered. Thanks to its properties, it is involved in the disintegration of the damaged lens. Damaged 20 lens, Chopper’s oval (101a, 101b, 101c) or basket-shaped (201) cutting edge It is crushed and broken by being squeezed. The oval and basket-shaped end part of the invention (101a, 101b, 101c, 201), (102) are flexible and highly resistant to breakage, this super Thanks to its elastic form, it easily returns to its original shape after changes. can come (101b, 101c). 25 The invention is made from a single piece of superelastic 0.8-1 mm thick NiTi wire, and the tip It consists of 2 parts, namely (101a, 101b, 101c, 201) and the body (102). The Chopper The tip (101a, 101b, 101c, 201) is oval or basket-shaped with a diameter of 3mm. The body (102) part is 45-60 mm long. The 30 used in the present invention The superelastic NiTi wire, deformed, enters through a 2mm hole and returns to its original form there. It is returning, that is, the shape of the end part (101a, 101b, 101c, 201) of the present invention. It passes through a 2mm hole, breaking it, and then returns to its original form. The tip of the invention. 4 (101a, 101b, 101c, 201) Thanks to this feature, you can easily reach the lens and the parts. can separate. The invention consists of a single piece of NiTi wire in the handle part (102), with the ends twisted together. They are combined. In the invention, the handle part (102) is a trigger for the surgeon to clean the defective lens. It is based on a mechanism that allows the surgeon to control the existing invention with the help of a trigger. is able to. 5 How the Invention Can Be Applied to Industry This invention is suitable for use in cataract surgery. Cataract It completes 10 surgeries in a shorter time than choppers currently used in surgeries. This allows the lens to be shattered while performing the operation in a less risky way. Because it provides this opportunity, it may be preferred by surgeons. Its use and application. Because it is easy, it reduces the impact of surgeon skill on the operation, and this Therefore, it may be the preferred choice of inexperienced surgeons.
