Description

Technical field: [0001] The invention relates to a surgical suture thread containing a combination of Chinese and Western bactericides or bacteriostatic agents. Background technique: [0002] Medical devices containing drugs have been used in the medical field to a certain extent. The clinical application of surgical sutures containing bactericidal or bacteriostatic drugs has just begun. US Patent Nos. US3987797, US4024871 and US6514517 and patent application Nos. US20040068293, US20040068294, US20050101993 and US2006264347 describe the composition of surgical sutures containing bactericidal or bacteriostatic drugs and the drug coating process. The common shortcoming of these inventions is that the contained medicine of surgical suture has bigger side effect to human body. The advantages of medical devices containing Chinese and Western fungicides or antibacterial agents are good clinical effects and small side effects. However, there is no precedent for surgical sutures ...
