1. A system comprising an intervertebral implant and a device to insert the intervertebral implant into a body, the intervertebral implant comprising a top surface, a bottom surface, and a side wall extending between the top surface and the bottom surface, the intervertebral implant having a hollow space having a spherical segment shape formed within the intervertebral implant and accessible through an elongate opening extending through a recessed portion of the side wall, and at least two guiding surfaces extending along an end of the intervertebral implant in an arc-shaped manner and facing one another such that the recessed portion of the side wall extends therebetween, wherein the device comprises:
a drive shaft including an engagement portion configured to engage the intervertebral implant in the hollow space; and
a sleeve movably holding and guiding the drive shaft and having a longitudinal axis, wherein the sleeve comprises an engagement structures;
wherein when the engagement portion of the drive shaft is received in the hollow space through the elongate opening and rotated by an angle about the longitudinal axis such that the engagement portion is supported in the hollow space, the engagement structure of the sleeve is configured to engage and slide laterally along the arc-shape of the at least two guiding surfaces, while being shaped to prevent rotation of the sleeve relative to the at least two guiding surfaces about the longitudinal axis.
