FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine and can be used in surgical operations. Eyeless sewing needle, in which periphery of axial hole near posterior needle end is heated in order to transform fibrous structure into granular structure without any orientation. At least one part of zone affected by heating, formed as a result of heating between fibrous structure and granular structure is in the area which is three times larger than sewing needle diameter and which passes from real base of axial hole to sharp tip.
EFFECT: provided is flexible sewing needle, due to which periphery of hole can be processes with preservation of hardness in position somewhat remote from axial hole.
