The invention discloses a coating method of an antibacterial surgical suture made of a high molecular absorbable material. The method comprises the following steps of: applying a dying process to a coating process; preparing a suture woven by using a warp loom; soaking a primary suture; uniformly spraying a coating liquid onto the suture by adopting a gas-free coating process; and drying and sizing. The suture is reddish violet and fresh in color, is smooth and flexible, is easy for knotting, has high knotting strength, and has the advantages of anti-inflammation, oxidation resistance, high degradability, long tension period and the like; and the safety of a knot is enhanced. The tensile strength is kept by about 70 percent two weeks after clinical suturing; slow absorption starts four weeks later; and the suture is absorbed completely 8-10 weeks later. As proved by clinical application, the antibacterial surgical suture has a wide application range and a good effect, is free from irritability, irritation and inflammatory reactions, and has the advantages of sterilization, anti-inflammation, bacteriostatic action and the like.

A magnetic vise comprises a holder, a movable portion, a rotary bar and a magnetic portion. The magnetic portion is located beneath the holder.
