Bulus konusu özellikle diz eklemi cerrahi uygulamalarinda kullanilan menteseli diz protezlerinde, femur ve tibia parçalarinin birbiriyle baglantisini saglayan kilit sistemi ile ilgilidir. Femur ve tibia protezlerinin birbirinden ayrilmasini (dislokasyon) önleyen ve tibia mediaI-lateral (internal-external) rotasyon hareketlerine müsaade eden dislokasyon kilit sistemi gelistirilmesi ile ilgilidir. Önceki Teknik Mevcut teknikte kullanilan menteseli diz protezlerinde femur ve tibia parçalarinin birbiriyle baglantisini saglayan ve medial-Iateral (internal-external) rotasyon hareketlerine müsaade eden cihazlar bulunmaktadir. Fakat mevcut teknikteki bu cihazlarda femur ve tibia parçalarinin çekme basma yönünde (dikey eksende / vertikal aks) birbirinden ayrilmasini önleyen bir kilit mekanizmasi bulunmamaktadir. Kilit mekanizmasi bulunan sistemlerde de mediaI-lateral (internal-external) rotasyon hareketleri yapilamamaktadir. Diger bir ifadeyle; baglanti, rotasyon ve çekme-basma yönünde (dikey eksende / vertikal aks) ayrilmama eylemlerini ayni anda saglayan bir kilit sistemi bulunmamaktadir. Diz protezlerinde kullanilan offset adaptörü femur ve tibia bölgesinde femoral ve tibial komponentlerin kemik yapisinda uygun eksenel sapma ve kaydirma islemlerini saglamak için oldukça önemli bir unsurdur. Fakat mevcut tekniklerde menteseli diz protezlerinde femur ve tibial parçalarinin ayrilmasini engelleyen baglanti mafsalinda kilit sistemi bulunmamasi nedeniyle baglanti mafsali uzun bir yapiya sahip olacak sekilde üretilmektedir. Baglanti mafsalinin uzun olmasi, özellikle menteseli ve/veya mafsalli tümör diz protezlerinde offset adaptörünün baglantisi için gerekli alan birakmamakta ve offset adaptörü kullanimini engellemektedir. Rotasyonlu menteseli diz sistemlerinde karsilasilan en büyük sorunlardan biri, femur ve tibia protezlerinin cerrahi uygulama sonrasinda çekme basma yönünde (dikey eksende / vertikal aks) birbirinden ayrilarak (dislokasyon) diz protezinin kullanilamaz hale gelmesidir. Bu durumun sonucu olarak hasta ikinci kez ameliyat edilmekte ve rotasyon özelligi olmayan sabit menteseli diz protezleri kullanilmaktadir. Mevcut teknikteki menteseli sistemlerde bütün yükleri göbek mili ve polietilen burç karsilamaktadir. Mevcut teknikte kullanilan menteseli diz protezlerinde polietilen burç asinmasina bagli olarak göbek mili ekseninde olusan yalpalama neticesinde protezdeki stabilitenin kaybolmasidir. Diz protezindeki stabilitenin kaybolmasiyla ve sürtünmenin etkisiyle polietilen burç zamanla yok olmaktadir. Bunun neticesinde metal-metal sürtünmesinden kaynaklanan metal debrizi (partikülleri) olusmakta ve bu partiküller kana karismaktadir. Bu gibi durumlarda hasta tekrar ameliyata alinarak hasarli parçalar yenisiyle degistirilmektedir. Hatta bazi durumlarda tüm sistem yenisiyle degistirilebilmektedir. Bu sebeple hasta birden fazla kez ameliyat geçirmekte ve bu durumdan psikolojik ve/veya maddi olarak önemli derecede olumsuz etkilenmektedir. Ayrica menteseli diz protezi uygulanan hastalarda bag ve yumusak doku kayiplari çok fazla oldugundan anatomik eksende dislokasyon riski oldukça fazla olmaktadir. Bu durum hasta sagliginin olumsuz etkilenmesine neden olmaktadir. Bulusun Amaci Bulusun amaci, yeni kilit sistemi ile femur ve tibia protezlerinin cerrahi uygulama sonrasinda çekme basma yönünde (dikey eksende / vertikal aks) birbirinden ayrilmasinin (dislokasyon) önüne geçilmesidir.

TR TR TR DESCRIPTION INNOVATION IN THE WORKING PRINCIPLE OF ROTATIONAL HINGED KNEE PROSTHESES Technical Field The subject of the invention is about the rotating hinged knee prosthesis designed to be used in knee joint tumor and revision surgery applications. The subject of the invention is related to the locking system that ensures the connection of the femur and tibia parts with each other, especially in hinged knee prostheses used in knee joint surgery applications. It is related to the development of a dislocation lock system that prevents the femur and tibia prostheses from being separated from each other (dislocation) and allows tibia medial-lateral (internal-external) rotation movements. Prior Art Hinged knee prostheses used in the current technique contain devices that connect the femur and tibia parts to each other and allow medial-Iateral (internal-external) rotation movements. However, these devices in the current technique do not have a locking mechanism that prevents the femur and tibia parts from being separated from each other in the tension-compression direction (vertical axis / vertical axis). In systems with a locking mechanism, medial-lateral (internal-external) rotation movements cannot be performed. In other words; There is no locking system that simultaneously provides the actions of connection, rotation and non-separation in the tension-compression direction (on the vertical axis / vertical axis). The offset adapter used in knee prostheses is a very important element to ensure appropriate axial deviation and shifting processes in the bone structure of the femoral and tibial components in the femur and tibia region. However, in current techniques, since there is no locking system in the connection joint that prevents the separation of the femur and tibial parts in hinged knee prostheses, the connection joint is produced to have a long structure. The long connection joint does not leave the necessary space for the connection of the offset adapter, especially in hinged and/or articulated tumor knee prostheses, and prevents the use of the offset adapter. One of the biggest problems encountered in rotational hinged knee systems is that the femur and tibia prostheses separate from each other (dislocation) in the tension-compression direction (vertical axis / vertical axis) after surgical application, making the knee prosthesis unusable. As a result of this situation, the patient is operated on for the second time and fixed hinged knee prostheses without rotation feature are used. In the hinged systems of the current technique, all loads are carried by the hub shaft and polyethylene bushing. In the hinged knee prostheses used in the current technique, the stability of the prosthesis is lost as a result of wobble in the hub shaft axis due to polyethylene bushing wear. The polyethylene bushing disappears over time due to the loss of stability in the knee prosthesis and the effect of friction. As a result, metal debris (particles) resulting from metal-metal friction are formed and these particles mix with the blood. In such cases, the patient is taken into surgery again and the damaged parts are replaced with new ones. In some cases, the entire system can even be replaced with a new one. For this reason, the patient undergoes surgery more than once and is significantly negatively affected psychologically and/or financially. In addition, the risk of dislocation in the anatomical axis is quite high in patients undergoing hinged knee prosthesis, as there is a lot of connective and soft tissue loss. This situation causes negative effects on patient health. Purpose of the Invention The purpose of the invention is to prevent the femur and tibia prostheses from being separated from each other (dislocation) in the tension-compression direction (vertical axis / vertical axis) after surgical application, with the new locking system. With the invention, - Superficial contact of the femoral component and polyethylene insert products is ensured with each other, - Incoming forces and resulting stresses are transferred to the tibial insert, - In this way, the wobble in the hub shaft axis due to polyethylene bushing wear is prevented and the life of the prosthesis is extended, - Thanks to the locking system, sufficient Ensuring the use of the offset adapter with the long connection joint produced in hinged and hinged tumor knee prostheses, - The risk of dislocation that may occur in the vertical axis due to the excessive ligament and soft tissue losses in patients undergoing hinged knee prosthesis is prevented, - The patient has to undergo repeated surgery. The necessity is eliminated. The structural and characteristic features and all the advantages of the invention will be understood more clearly thanks to the figures given below and the detailed explanation written by referring to these figures. For this reason, the evaluation should be made taking these figures and detailed explanation into consideration.

Offset Adapter Slot A: First Ring Section B: Second Ring Section The dislocation lock system that is the subject of the invention is used for the hinged tumor knee and hinged revision knee used for tibia and femur bones. It is shown in Figure-1, Figure-2, Figure-3 and Figure-4 to be used in the system. Figure - 5 and Figure - 6 show the disassembled state of the knee prosthesis locking system for the femoral stem (10) in the upper part, which forms the bone structure of the knee joint, and the tibial stem (11) in the lower part. The assembly of the parts forming the femur region of the locked knee system is shown in Figure - 7 and Figure - 8. Polyethylene bushings (2) with the same size as the component holes (1.1) are placed in the component holes (1.1) opened on both sides and inside of the femoral component (1) to form the femur region. Polyethylene bushing holes (2.1) are opened on the polyethylene bushings (2). The polyethylene bushings (2) with polyethylene bushing holes (2.1) placed in the component holes (1.1) and the connection joint (3) with a cylindrical structure is positioned in the distance between the component holes (1.1) shown in Figure - 7. The round shaped hub shaft hole (3.3) located on the upper part of the cylindrical connecting joint (3) is placed on the distance between the polyethylene bushings (2) placed on the component holes (1.1), with the round part sideways. (Figure - 8) It is placed by aligning the hub shaft hole (3.3) on the connection joint (3) with the polyethylene bushing holes (2.1) on the polyethylene bushing (2). The hub shaft (4) seen in Figure - 7 is placed by passing between the component holes (1.1) and the hub shaft holes (3.3) located opposite each other. The hub shaft slot (4.1) on the hub shaft (4) and the set screw hole (3.1) on the connection joint (3) are aligned with each other. Thanks to the hub shaft set screw (5), the connecting joint (3) is fixed to the femoral component (1) by placing the corresponding set screw hole (3.1) in the femoral component (1) and the hub shaft slot (4.1). Thus, the femur region of the system is completed. (Figure - 9) The parts forming the tibia region of the dislocation lock system are shown in detail in Figure-11, Figure-12 and Figure-13. The top view of the polyethylene insert (6), which is one of the parts forming the tibia region, is shown in Figure - 10. A lock slot (6.1) is formed within the round-shaped connection joint slot (6.3) opened on the polyethylene insert (6) to form the tibia region. The polyethylene lock (7) piece, seen in the shape of a half-moon, is placed in the round-shaped lock slot (6.1) formed within the connection joint slot (6.3) by stretching it in the closing direction. (Figure - 21, Figure- 22) When the polyethylene lock (7) part, which is placed by stretching in the closing direction, reaches the lock slot (6.1), it returns to its previous position as the stretching force disappears and remains fixed on the polyethylene insert (6). (Figure - 23) The fixing of the polyethylene lock (7) to the lock slot (6.1) is shown in detail in the first ring section (A) in Figure - 24. A tube hole (8.1) is opened into the tibial component (8) shown in Figure 12, which is another of the parts that make up the tibia region. The opened tube hole (8.1) is located in the middle part of the tibial component (8) and a cylindrical polyethylene tube (9) is placed inside. The clawed pins (8.2) with a protruding structure located on the right and left sides of the tibial component (8) are brought together with the bean-shaped polyethylene insert slots (6.2) located on the right and left sides on the polyethylene insert (6) and by applying pressure force, they are placed in the polyethylene insert slots. (6.2) is fitted. (Figure - 25) Thanks to this pressure force, the polyethylene insert (6) and the tibial component (8) are locked. The locking of the claw pins (8.2) with the polyethylene insert slots (6.2) is shown in detail in the second ring section (B) in Figure 26. Thanks to the male-female connection system of the polyethylene insert slots (6.2) and the clawed pins (8.2), the polyethylene insert (6) part is prevented from separating from the tibial component (8). Thanks to the bean-shaped shape of the polyethylene insert slots (6.2) on the polyethylene insert (6), the claw pins (8.2) placed on the polyethylene insert slots (6.2) are given mobility. Thanks to its mobility, the polyethylene insert (6) provides internal-external rotation movement. (Figure - 14, Figure - 15, Figure - 16, Figure - 17) The disassembled state of the femur and tibia parts, which were assembled separately, is shown in Figure - 18. The connection joint (3), one of the assembled femur parts, is placed in the connection joint slot (6.3) on the polyethylene insert (6) one of the assembled tibia parts. The rounded end part (3.4) of the connection joint (3) advances by stretching the polyethylene lock (7) part placed inside the polyethylene insert (6) in the opening direction. As the connection joint (3) advances into the polyethylene lock (7), the polyethylene lock (7) reaches the invoice area (3.2) created on the connection joint (3). The bill region (3.2) is a cylindrical region with a smaller radius in the middle part of the connection joint (3) and creates a diameter decrease. Since the opening force on the polyethylene lock (7) part will disappear, the polyethylene lock (7) part closes again to its previous position. With the closing action of the polyethylene lock (7) part, the assembled femur and assembled tibia parts are prevented from separating from each other. (Figure - 19) When the locking process of the femur and tibia parts is performed, the condyle surfaces (1.2) located on the lower part of the femoral component (1), right and left, and the rolling surfaces (6.4) located on the right and left sides on the upper part of the polyethylene insert (6). They are placed on top of each other to ensure superficial contact between them. The connection of the femur and tibia parts, which are assembled separately, to the femoral stem (10) and tibial stem (11) is provided by the offset adapter (12). In order to connect the femur parts to the femoral stem (10), the lower part of the cylindrical offset adapter (12) is placed into the round and conical shaped offset adapter slot (14) located on the upper part of the femoral component (1). The conical lower part of the femoral stem (10) is placed on the upper part of the offset adapter (12), and thanks to the offset adapter set screw (13), the offset adapter (12) serves as an intermediate element by connecting the femoral component (1) and the femoral stem (10). For the connection of the tibia parts to the tibial stem (11), the upper part of the cylindrical offset adapter (12) is placed into the round and conical shaped offset adapter slot (14) located in the lower region of the tibial component (8) from the lower part of the tibial component (8). The conical upper part of the tibial stem (11), which has a cylindrical form, is placed at the bottom of the offset adapter (12), and the offset adapter sets screw (13) and the offset adapter (12) serves as an intermediate element by connecting the tibial component (8) and the tibial stem (11). . (Figure - 5) Thus, by using the offset adapter (12) in knee prostheses, appropriate axial deviation and shifting processes are provided in the bone structure of the femoral component (1) and tibial components (8) in the femur and tibia region. All kinds of forces and resulting stresses on the knee prosthesis are transferred to the polyethylene insert (6) piece. (Figure - 20) By transferring the incoming forces and the resulting pressures to the polyethylene insert (6) part, the wobble that occurs in the hub shaft (4) axis due to the wear of the polyethylene bushing (2) is prevented and the life of the prosthesis is extended. In the alternative application, the locking of the femur and tibia parts is done with the connection ears (3.5) added to the connection joint (3). A lock slot (6.1) is formed within the round-shaped connection joint slot (6.3) opened on the polyethylene insert (6). The connection joint (3) advances into the round-shaped lock slot (6.1) created within the connection joint slot (6.3). The locking process is provided by the lock slot (6.1) which provides a suitable position reference to the connection ears (3.5). As the connection joint (3) advances within the connection joint slot (6.3), the connection ears (3.5) located on the connection joint (3) reach the lock housing (6.1). The locking process takes place when the connection ears (3.5) reach the lock slot (6.1).TR TR TR
