ANASTOMAT-USE ABSORBABLE SUTURING STAPLE

摘要

Disclosed is an anastomat-use absorbable suturing staple, consisting of a suturing staple main body made of a medical degradable magnesium alloy filament material, a degradable biological ceramic film underlying layer attached onto the surface of the magnesium alloy filament material, and a degradable polymer surface layer for use in sealing treatment. The double layer protection formed by a surface degradable ceramic coating layer and by a polymer film and the sealing effect that an organic coating layer has on the surface of the inorganic ceramic coating layer allow for effectively improved anticorrosion properties of the anastomat-use absorbable suturing staple, and control the degradation rate of the suturing staple. The disclosed anastomat-use absorbable suturing staple can be completely absorbed in the in vivo environment and, at the same time, provides the necessary properties for resistance against acidic or alkali corrosions in the early postoperative phase, is capable of resisting early-phase corrosive damages of the highly acidic intragastric environment, and is applicable in various surgeries in the human body and particularly suitable for postoperative anastomosis and suturing of the digestive tract.
