A surgical suture apparatus for passing a double-ended surgical needle forwards and backwards includes a main body, a first jaw element and a second jaw element, each including a holding device to hold a needle-end of the surgical needle. The first jaw element and second jaw element are movable with respect to each other between a take-over position, where a surgical needle can be passed between the first holding device and the second holding device, and an open position. The surgical apparatus further includes an operating device to operate the first holding device and the second holding device to alternately hold the first needle-end by the first holding device and the second needle-end by the second holding device, where the first jaw element is detachably mounted on the main body.
