摘要： 生物降解高分子材料的最大特点是能在体液、酶和细胞等的作用下发生降解, 变成低分子物质被吸收或通过新陈代谢排出体外, 因而做为一种临时性的支架或修复材料, 如骨固定材料[ 1]、手术缝合线[ 2]、人造皮肤[ 3]等, 可以起到很好的治疗作用, 又不需二次手术取出, 可以极大地减少病人的痛苦. 粘连是外科手术中常见的后遗症. 本文将稀土配位催化剂制备的 ε-己内酯/d, l -丙交酯共聚物和 ε-己内酯均聚物, 用溶液浇铸方法成膜, 植入兔子体内, 观察了聚合物膜在兔子体内的防肌键粘连作用及生物降解行为.

Abstract: ε-Caprolactone(ε-CL)/d,l lactide(DLLA)copolymer films with thickness of 40 μm were prepared by solution-casting and implanted into rabbit body to cover the ruptured achilles tendons for preventing tendon adhesion with surrounding tissues. The biodegradation of ε-CL homopolymer film and ε-CL/DLLA copolymer film in rabbit body were also studied. The ε-CL/DLLA copolymer film could decrease postoperative adhesion of the tendon, and it degraded entirely within 24 weeks.

Key words: tendon adhesion, biodegradation, polymer film
