Stitching formation by a suturing instrument

摘要

A suturing instrument is used to form stitchings including stitching formation made by causing a shuttle thread to move in reciprocation on cut edges of a human part, between knottings and next knottings in a lock stitching, via an outer side of a needle thread at a needle-out-hole from a needle-in-hole of a needle, thereby to make conglutination of the cut part stable and sound. In a method of suturing cut edges of human parts in a surgical operation the shuttle thread crossed with the needle thread traverses over the cut edges from the needle-out-hole to the needle-in-hole of the next stitch and passes under the outside of the needle thread carried by the needle. The shuttle thread then again traverses over the cut edges to the needle-out-hole of the next stitch.
