MEANS FOR FIXING PROSTHESES, METHOD OF INSERTING A PROSTHESIS INTO A GRAIN BED AND A PROSTHESIS INSERTION UNIT

摘要

A method and an insertion unit for inserting an elongate prosthesis into a prosthesis fixing device. This device comprises a bed of grains and biocompatible material, and a vibrating tool is used for insertion, the vibration head of which performs an oscillating motion back and forth about a swivelling axis (3') . According to the invention, said axis (3r) of the vibrating tool essentially coincides with the longitudinal axis (I1) of the elongate prosthesis (1) . The method and the insertion unit provide a prosthesis fixing device consisting of said bed, in which the grains are evenly packed along the length of the prosthesis.
