Document Type and Number:
Japanese Patent JP6896241
Kind Code:
B2
Abstract:
Provided is a medical suture thread which is less likely to remain curled or is easily uncurled from a curled state. The medical suture thread 100 includes a core thread 110 and an outer thread 120. The core thread 110 includes multiple twisted ultrafine threads 111, and is arranged at a center portion of the medical suture thread 100. In the ultrafine thread 111, an inner-filament cover layer 112 made of 2-methacryloyloxyethyl phosphorylcholine (MPC) is formed on an outer surface of a filament 111a. The outer thread 120 is formed to be braided with multiple ultrafine threads 121, and covers an outer surface of the core thread 110. In the ultrafine thread 121, an outer-filament cover layer 122 made of MPC is formed on an outer surface of a filament 121a. The inner-filament cover layer 112 and the outer-filament cover layer 122 are respectively formed on the outer surfaces of the filaments 111a, 121a within a weight range of equal to or greater than 0.05% and less than 0.3% with respect to the total weight of each of the filaments 111a, 121a, respectively.
