An insertion instrument for hip endoprosthetics for inserting socket inserts into endoprosthetic hip sockets having holding claws which are connected to a substantially ring-shaped support element through spring elements, wherein the insertion instrument can be placed on the socket insert and can be connected to said socket insert through the holding claws. In order for the user to receive direct palpatory information about the events in the operation areas and to not suffer a perceived loss of control, it is proposed that the support element surround a freely accessible, substantially circular effective insertion area, the center point of which is located on the longitudinal axis of the insertion instrument.

Insertion instrument for inserting socket inserts into the spherical recesses of hip sockets

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.
