An insertion instrument for instrumented insertion of a socket inset () with a spherical cap () into a hip socket () of a hip-joint prosthesis, having an impacting instrument () with a handle (), at one end of which a holding tool for the socket inset () is located. In order to avoid tilting of the socket inset during insertion, it is proposed that the one end () of the impacting instrument () has a spherical shape and is part of the holding tool, and the holding tool furthermore comprises an impacting head (), which is designed as a separate component and received the spherical end () of the impacting instrument () in an articulated manner, and an insertion aid (), which is designed as a separate component and serves to hold the socket inset () on the outer geometry of the impacting head (), and the impacting head () can be connected to the spherical end () to form a ball joint.

Insertion instrument for inserting socket insets into hip sockets for hip endoprostheses

A tool for placing or removing joint sockets of an artificial joint, especially a hip joint, and a tool for placing or removing an artificial joint, has a handle, a joint socket or joint receiver or holder, and a connecting element arranged between the handle and the joint socket or joint holder. The connecting element comprises an arcuate portion in its longitudinal direction. A system for placing and removing joint sockets or joints using such a tool includes a position-determining and navigation device.
