Description

TARIFNAME BIR RADIUS BASI PROTEZI Teknik Alan Bulus, kirik veya kireçlenme sonucu orijinalligi bozulan kol dirsek eklemindeki radius basi kemiginin onarilmasini saglayan bir protez ile ilgilidir. Önceki Teknik Radius ön koldaki kemiklerden biridir. Anatomik durus pozisyonuna göre radius ön kolun lateral (basparmak tarafinda) kisminda yer almaktadir. Dirsekte humerusla, el bileginde ise skafoid kemik ve lunatum kemigi ile eklem yapmaktadir. Ön koldaki iki kemikten hareketli olan kemiktir ve ön kolun kendi ekseni etrafinda dönmesine yardimci olmaktadir. Bu kemik siklikla el üzerine düsme sonucunda, yani indirek olarak kirilmaktadir. Söz konusu kirigin giderilmesi için mevcutta kullanilan protezler bulunmakta ancak bu protezler kemik kirigini onarirken herhangi bir yük ile karsi karsiya kaldiginda kikirdak dokuyu koruyamamakta baski sonucu yeni zararlara yol açmaktadir. Bu sebeple kullaniin sirasinda vücutta yeni bir zarara neden olmayan yeni radius basi protezine ihtiyaç duyulmaktadir. dokümaninda, bir radius basi protezinden bahsedilmektedir. Protez; bir baglanti çubugu, bir ek parça ve bir radyal basliktan olusmaktadir. Radyal baslik üst kisminda anatomik iç bükey bir oyuk içermektedir. Baglanti çubugu ile ek parça ve ek parça ile de radyal baslik saplama ve oyuk parçalar sayesinde birbiri ile birlestirilmektedir. Protez üç parçadan olusan modüler bir yapidadir. Söz konusu bulus, osteoporozdan muzdarip hastalarda ve kirik kemiklerde kullanilabilmektedir. DESCRIPTION A RADIUS PRESSURE PROSTHESIS Technical Area Invention, fracture or calcification as a result of the original deteriorated arm elbow joint It is related to a prosthesis that provides repair of the radius head bone. Prior Art Radius is one of the bones in the forearm. Radius according to anatomical posture It is located on the lateral (on the thumb side) part of the forearm. at the elbow articulate with the humerus, and with the scaphoid bone and lunate bone in the wrist doing. It is the movable bone of the two bones in the forearm and is the forearm itself. It helps it rotate around its axis. This bone is often on the hand As a result of falling, that is, it is broken indirectly. The said border There are prostheses currently used for removal, but these prostheses cartilage when it is faced with any load while repairing a bone fracture not being able to protect the tissue causes new damages as a result of pressure. Therefore New radial head that does not cause any new damage to the body during use prosthesis is needed. In the document, a radius head prosthesis is mentioned. Prosthesis; a link rod consists of an insert and a radial head. radial header top It contains an anatomical concave cavity in its part. Attachment with connecting rod and with the additional part, they can be connected to each other thanks to the radial head stud and hollow parts. are combined. The prosthesis has a modular structure consisting of three parts. Aforementioned The invention is used in patients suffering from osteoporosis and broken bones. can be used.

Teknigin bilinen durumunda yer alan U86709459 sayili Birlesik Devletler patent dokümaninda, bir hastanin dirsek ekleminde kullanilan ve anatomik hareketleri taklit edebilen bir radius basi protezinden bahsedilmektedir. Protez, bir bas, kavisli bir sap (gövde) ve bas ile kavisli sap arasinda baglanti saglayan bir baglanti elemani içermektedir. Bas kisim bir girinti ile olusturulmakta ve girinti iç bükey seklinde olmaktadir. Kavisli sap, kobalt-krom veya titanyum gibi bir malzemeden yapilmaktadir ve yüzeyi pürüzlüdür. Baglanti elemaninin yüzeyi, titanyum, kobalt-krom boncuklar veya hidroksiapatit gibi bir malzeme ile kaplanabilmektedir. Bunun yani sira bas kismi ve özellikle girintinin yakin yüzeyleri, çok parlak bir kobalt-krom veya seramik bir malzemeden yapilmaktadir. dokümaninda, bir protezden bahsedilmektedir. Protez; temel olarak bir eklem bas elemani ve bir sap kismindan olusmaktadir. Eklem bas elemani; bir birinci kafa bileseni ve bir ikinci kafa bileseni içermektedir. Ayrica birinci kafa bileseni ve ikinci kafa bileseni arasinda teleskopik bir mekanizma yer almaktadir. Teleskopik mekanizma; birinci kafa bileseninin ikinci kafa bilesenine göre göreceli uzunlamasina konumlandirilmasini ayarlamakta kullanilmaktadir. Protez için uygun yükseklik belirlendikten sonra sabitleme Vidasi ile istenilen yükseklik korunmaktadir. United States patent numbered U86709459, which is in the state of the art. In the document, the anatomical movements used in the elbow joint of a patient and A radius head prosthesis that can imitate is mentioned. prosthetic, a bass, a curved neck (body) and a connection between the head and the curved neck Includes connector. The head part is formed with an indentation and the indentation is curved. A curved handle, such as cobalt-chrome or titanium It is made of material and has a rough surface. The surface of the fastener, with a material such as titanium, cobalt-chrome beads or hydroxyapatite can be covered. In addition to this, the bass part and especially the close of the recess surfaces of a high-gloss cobalt-chrome or ceramic material. is being done. In the document, a prosthesis is mentioned. Prosthesis; basically a joint bass element and a handle part. joint bass element; a first head component and a second head component.
