摘要：
An insertion instrument for instrumented insertion of a socket inset (4) with a spherical cap (20) into a hip socket (5) of a hip-joint prosthesis, having an impacting instrument (1) with a handle (7), at one end of which a holding tool for the socket inset (4) is located. In order to avoid tilting of the socket inset during insertion, it is proposed that the one end (8) of the impacting instrument (1) has a spherical shape and is part of the holding tool, and the holding tool furthermore comprises an impacting head (2), which is designed as a separate component and received the spherical end (8) of the impacting instrument (1) in an articulated manner, and an insertion aid (3), which is designed as a separate component and serves to hold the socket inset (4) on the outer geometry of the impacting head (2), and the impacting head (2) can be connected to the spherical end (8) to form a ball joint.
