Abstract
A needle driving device (1) includes a pivotally mounted needle holder (3) for a curved suturing needle (12). Following the initial pivot the needle driving member (16) is actuated for pushing the needle out of the holder. The pointed end of the needle (14) is thereby pushed to the surface of the sutured tissue. The needle is drawn outside the aperture by a pair of tongs and a surgeon may bind an initial knot on the thread. Slots (51) arranged at the ends of two V-shaped prongs enable the knot to come into contact with the tissue. The knot is then completed and brought into contact with the tissue. As the thread guides are separated an outward pull is effected which makes it possible to tie a knot even in very deep surgical apertures.
