Definitions

• the invention relates first of all to a method for receiving a medical element on a handling device, wherein the medical element is received by means of a receiving element such that it can be inserted or removed from the implant by means of a handling device having the receiving element in an implant, wherein the receiving element in a Longitudinally a Trohahmeausnaturalung of the medical element is introduced into the Aufhahmeausnaturalung and secured in the Aufhahmeausnaturalung by means of a clip member against displacement in the longitudinal direction.
• the invention further relates to a handling device for a medical element, comprising a receiving element by means of which the medical device is aufhehmbar for insertion into an implant or for removal from the implant, wherein the receiving element in a receiving recess of the medizim 'rule element in a longitudinal direction of the Aufhahmeaus strictlyung can be introduced and secured by a clip member against displacement in the longitudinal direction, and finally an implant that can be implanted by screwing into a Aufhahmebohrung in a bone.
