TH41941B - Holeless Sewing Needles and Holeless Sewing Needles - Google Patents

Abstract

DC60 The periphery of the axial hole at the base end in the perforated needle. Has been heated to do The fibrous structure provides directional free granular structure. And part of the area At least one part of the thermal impact has been done between the fibrous structure and the Pellets due to heating are within the range That is, three times the diameter of the suture needle, and which leads from the base of the axial hole to the needle end of the needle. This allows for a sewing needle. So that the periphery of the axial hole can be treated And to maintain Hardness condition at the position of the needle tip slightly away from the axial hole so that the needle cannot Bends even if it gets caught near an axial hole. The periphery of the axial hole at the base end in the perforated needle. Has been heated to do The fibrous structure provides directional free granular structure. And part of the area At least one part of the thermal impact has been done between the fibrous structure and the Pellets due to heating are within the range That is, three times the diameter of the suture needle, and which leads from the base of the axial hole to the needle end of the needle. This allows for a sewing needle. So that the periphery of the axial hole can be treated And to maintain Hardness condition at the position of the needle tip slightly away from the axial hole so that the needle cannot Bends even if it gets caught near an axial hole.

Claims (4)

Disclaimers (all) that will not appear on the advertisement page: 1. A hole-less suture needle consisting of a main body section with a curved axis. Spanning from the end The base to the tip of the needle is sharp and has been made from austenite stainless steel. With a fibrous structure, where the crystalline structure of the main body part extending along the axis It is also further assembled. An axial hole leading from the end of the base where the periphery of the axial hole at the end of the base is heated. To make the structure The fibrous form is a granular structure without being dependent on the direction and part of the impact area. At least one part is heated between the fibrous structure and the granular structure. Due to such heating It is within a range of three times the diameter of the suture needle and runs from the base of the axial hole to the needle end of the needle. 2. Holeless sewing needle according to claim 1, where the range is approximately a quarter of the needle length away from the base end of the main body. And next to the end of the needle Will not consist of a granular structure But consisted of hot affected areas Or fibrous structures 3.How to produce a holeless needle It consists of a curved axial main body that leads from the base to the point of the sharp needle. And that consists of axial holes leading from the base end where the main body has a crystal structure. Made of austenite stainless steel With a line structure Strands along the axis That the method consists of steps of Heating the periphery of the axial hole at the base end. To make the filament structure into a granular structure Without being dependent on direction and formation, the affected area is heated between the fibrous structure and the granular structure through heating where the affected area is heated. At least part In a range that is three times the Stitch diameter And that leads from the base of the axial hole to the needle end of the sewing needle 4.How to produce a holeless needle According to claim 3, where the range is approximately a quarter of Needle length away from the base of the main body And the next line to the end of the needle will not consist of a grain structure. But consists of a hot affected area or a fibrous structure
