Document Type and Number:
Japanese Patent JP6896240
Kind Code:
B2
Abstract:
Provided is a medical suture thread as a multifilament, which is formed easily bendable and ensuring favorable operability. 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.
