Abstract
An instrument set for minimally invasive preparation for a bone nailing comprises at least one base sleeve () which has a selected axial length with a drive-in end and a tool working end () and an inner diameter selected for holding working sleeves () or a nail, in particular a medullary pin. Further, the instrument set comprises at least one substantially rigid guide wire () which has a selected diameter and a fixing tip () at one end, at least one dilation sleeve () which has an outer diameter adapted to the inner diameter of the base sleeve () for guided displacement therein, an end section () tapering away therefrom with an outlet opening () for the guided longitudinal displacement of the guide wire () through this, and a length which is greater than that of the base sleeve (), and at least one working sleeve () which has an outer diameter adapted to the inner diameter of the base sleeve () or next largest working sleeve for guided displacement therein, a length which is greater than that of the base sleeve (), an inner diameter adapted for guidance of a bore or cutter () or a nail to be inserted, and a stop () at its one end for working with the tool working end () of the base sleeve ().
