摘要

为了恢复椎间盘的生物力学功能，我们提出了几种类型的装置来关闭纤维环缺损。选用聚丙交酯、聚ε-己内酯以及聚丙交酯与ε-己内酯的共聚物作为材料。材料的压缩模量值范围为0.54至210 MPa，具体取决于所开发设备的组成和结构。由聚乳酸和聚己内酯共聚物制成的海绵状装置最有希望进行进一步的体内研究。

Biodegradable Devices Based on Blends of Polylactide and Polycaprolactone and Their Copolymers for the Closure of Fibrosis Annulus Defects after Sequestrectomy of the Intervertebral Disc

Several types of devices are proposed for closing annulus fibrosus defects after sequestrectomy to restore the biomechanics of the intervertebral disc. Polylactide, poly-ε-caprolactone, and copolymers of lactide and ε-caprolactone are selected as the materials. The compressive modulus values of the materials range from 0.54 to 210 MPa, depending on the composition and structure of the devices being developed. Sponge-type devices made from copolymers of polylactide and polycaprolactone show the most promise for further in vivo research studies.
