A suturing machine for suturing incised parts of a patient by producing continuous stitches by means of a curved needle and a shuttle includes a pair of grips terminated with jaws adapted to hold the curved needle which forms a thread loop on the parts to be sutured. A shuttle holder is slidably positioned on one of the grips to move the shuttle with a shuttle thread towards the curved needle to produce a lock stitch with the thread loop. The shuttle holder functions when the needle is standstill.
