Embodiment Construction

[0029] figure 1 A cross-section of the bone nail (or intramedullary pin) according to the first embodiment is shown. The bone nail 10 generally corresponds in its external shape to that of a conventional bone or intramedullary nail.

[0030] The bone screw 10 inventively consists of a metal inlay 20 formed as a load-bearing part and a plastic body 30 of biocompatible polymer with this connection.

[0031] With this first embodiment, it is provided in particular that, except for the proximal side of the bone screw 10 , the entire surface is completely coated with a biocompatible material.

[0032] The metal inlay 20 shows in its proximal region two metal inlay 20 circulation grooves 22 in which the plastic body 30 is clamped and thus fixed against sliding relative to the metal inlay 20 .

[0033] figure 2 A cross-section of a bone screw according to a second embodiment is shown. figure 2 The bone nail 10 shown corresponds substantially to figure 1 The embodiment shown di...

Abstract

The invention relates to a method for producing an osteosynthetic implant, comprising the steps of producing a load-bearing metal component and coating the load-bearing component with a biocompatible material.

Description

technical field [0001] The invention relates to a method for producing an implant for osteosynthesis. The invention also relates to a bone nail. Background technique [0002] Implants for osteosynthesis used in traumatology are known, for example, from EP1488752A1. The very laborious and time-consuming machining process used to produce the body profile shape and load-bearing function parts proved to be a disadvantage. These processes require proper time in manufacturing and complex and time-consuming processes in quality control. Although these methods have been largely optimized in the last decade, they now offer very little opportunity to reduce labor and thus also cost. Contents of the invention [0003] The object of the present invention is therefore to provide a method for producing an implant for osteosynthesis which hardly requires any time- and labor-intensive manufacturing techniques, resulting in a relatively cheap and at the same time high-quality product. ...
