摘要： An extractor is provided to extract an insert used with a bone connection element such as a bone plate having at least one opening for a bone screw used with the insert. The extractor has an outer hollow sleeve having proximal abutment surface for engaging a surface portion of the bone plate, and an inner bar having a diameter enabling the insertion of the bar into the hollow sleeve. The bar has a threaded leading end to engage the thread of the insert to be extracted. The hollow sleeve has an inner thread and the inner bar has an outer threaded element for engaging the inner thread of the hollow sleeve. The outer threaded element is positioned with respect to the bar in a longitudinal position to enable the threaded locking end to extend beyond the proximal abutment surface of the sleeve to be threaded into the insert.

摘要： The invention relates to an implantable orthopaedic device comprising a load-bearing element, such as a bone plate, for fixing elements, such as bone screws, that can be oriented polyaxially. The load-bearing element is equipped with at least one opening for the passage of the fixing elements. A two part insert is provided in the opening, the insert having an external form that complements the internal form of the receiving opening and permits the polyaxial rotation of the insert in the opening. The insert is equipped with a central bore for receiving the body of the fixing element. The first insert element part has a central inner hollow chamber, into which the second insert element part can be introduced. The first insert element is flexible or has at least one slit, in such a way that when the two insert elements are displaced axially in relation to one another, the first insert element in the plate can be expanded at least partially in order to block the position and alignment of the fixing element in the device in a polyaxial manner.
摘要翻译：本发明涉及一种可植入矫形装置，其包括用于诸如骨螺钉的固定元件（例如骨板）的承载元件，其可以被多轴定向。承载元件配备有用于固定元件通过的至少一个开口。两个部分的插入件设置在开口中，插入件具有补充接收开口的内部形式的外部形式并且允许插入件在开口中的多轴旋转。插入件配备有用于接收固定元件的主体的中心孔。第一插入元件部分具有中心内部中空室，可以将第二插入元件部分引入该中空室。第一插入元件是柔性的或具有至少一个狭缝，以这样的方式，当两个插入元件相对于彼此轴向移位时，板中的第一插入元件可以至少部分地膨胀以阻止固定元件以多轴方式在装置中的位置和对准。
