1 TARIFF SAFE AND COMPREHENSIVE METAL CUTTING TIP FOR INTERVERTEBRAL DISCS. Technical Field to Which the Invention Relates 5 The invention is compatible with standard scalpel handles for use in spinal surgery. with a metal cutting insert that can make a safe and effective incision in the intervertebral disc It is related. State of the Art 10 The spine is made up of a series of bones that connect and support the vertebrae. Between the vertebrae are discs called intervertebral discs, which act as cushions. These discs provide flexibility to the spine and absorb shock during movement. It performs. The discs consist of a core filled with a gelatinous substance and surrounding it. It consists of a tough fibrous ring. Due to aging and other factors, discs degenerate. This can lead to a decrease in disc height and intervertebral disc space. This can cause narrowing. A narrowed disc space can put pressure on nerve roots and Sciatica can cause symptoms such as leg pain, numbness, and tingling. If symptoms are severe or do not respond to medication, surgical treatment is necessary. It is possible. In surgical treatment, an incision is made in the disc space to relieve pressure on the nerve roots. 20 is reduced. This procedure can be performed using various methods: In the microdiscectomy method, small A portion of the disc material is removed through an incision. Endoscopic discectomy. In this method, small incisions are made in the skin, a camera and surgical instruments are inserted, and a disc is placed. In the fusion method, the material is removed. In the fusion method, the vertebrae are fixed together to provide stability. This is ensured. During this and similar surgical procedures, nerve root retraction is 25%. then, using a scalpel, the outer layer, mostly called the annulus fibrosus, A careful incision is made in the fibrotic tissue, without damaging the surrounding tissues, and the disc is removed. An area is created to drain the tissue between the incisions. After the incision, a punch is inserted. The disc space is cleared using an instrument called [instrument name]. Care should be taken when making the incision. It is necessary to ensure that the sharp edge of the scalpel does not come into contact with neural tissue, this 30 in addition to this, the disc tissue under the posterior longitudinal ligament is also removed. A partial incision is required. This procedure is sometimes performed in a location that is difficult to access. As is the case in the region, sometimes the scalpels are damaged due to the thin-bladed structure of classic scalpels. The abdominal aorta can rupture during the operation, which can be very life-threatening. 2 damage, advancement of the scalpel into the intra-abdominal space, damage to various organs It can lead to complications such as stabbing. Spinal surgery is becoming increasingly important in the treatment of pathologies in the spinal structure. and the technical advancements in this field are both increasing the surgical success rate and 5 It also improves patient comfort. This is one of the most critical stages during these surgeries. one of them, with a safe, controlled and minimal tissue damage to the intervertebral disc region It is necessary to intervene. Especially in cases of disc herniation, degenerative disc disease, and spinal stenosis. or in surgical procedures performed in conditions such as vertebral instability, The incision made in the intervertebral disc directly affects the success of the surgery. This is one of the fundamental steps. Therefore, when making an incision in the disc, both the surrounding tissues must be protected. Both protection and ensuring an accurate intervention in the targeted area are of great importance. This is of great importance. Specialized surgical instruments developed in recent years meet this need. It is designed to facilitate the surgeon's access to the disc and the incision. It provides greater control over depth, direction, and width. These tools; 15 microsurgical blades, cutting instruments compatible with endoscopic systems, and sometimes devices with different mechanisms, such as those that operate with laser or ultrasonic energy It is possible. The use of these instruments allows for safe and effective incisions. Thanks to this, the operation time is shortened, the risk of bleeding is reduced, and recovery is improved. The process happens faster. Therefore, the incision developed specifically for spinal surgery is 20 detailed technical specifications, ease of use, and clinical effectiveness of the instruments This examination contributes to both surgical practices and instrument design. It offers. In the current technique, cutting tools used in spinal surgery make incisions. This necessitates the insertion of a stud into the disk space, and this is uncontrolled and This results in an incision being made far from safety. Also, the blade tips are 25... Once the tool becomes dull, it becomes necessary to replace it. In the known state of the art, anterior to patent document number CN112137689B Regarding the problem of posterior longitudinal ligament transection after cervical surgery. It provides a solution. The product mentioned in this document has a cutting structure on both sides. 30 It has this feature. Therefore, it is possible to perform a safe discectomy procedure. It is not. Also, the tip is inherently thin and easily breaks. It is available. In addition, it is fixed, not in the form of a headpiece, meaning the blades will not become dull. After that, the device will need to be replaced again. 3 In another known instance of the art, utility model number TR2005 / 00243 the document connects to the pedicle screws used in the posterior stabilization procedure and the rods that determine the lordosis and angulation of the spine. with a hook system that allows the angles of the rods to be adjusted as desired It is related. This hook mentioned is suitable for use in spinal surgical procedures. 5 Despite this, making an incision in the intervertebral disc space preserves neural tissues. It has no such purpose. In another known instance of the art, utility model number CN211156098U The document describes how to make precise skin incisions for use in endoscopic spinal surgery. It involves a knife that can make this kind of incision. The incision made with this knife is on the intervertebral disc. It does not enter the gap; it remains on the skin's surface. The limitations and inadequacies of current technical solutions in spinal surgery The cutting tools used in the intervertebral disc space have a high probability of fracture. 15 its presence, the risk of damaging surrounding tissues, its sharp and pointed edges, safe and preventing the incision from being made thoroughly, after the blade tips become dull the need to change the instrument again, inserting a screw into the disc space for making the incision For reasons such as the necessity of doing so, it is necessary to make improvements in this area. It has been made. 20 Brief Description and Objectives of the Invention The invention is compatible with standard scalpel handles for use in spinal surgery. with a metal cutting insert that can make a safe and effective incision in the intervertebral disc It is related. 25 One aim of the invention is to provide safe and comprehensive intervertebral disc space in spinal surgery.
