Title
(EN) Bioabsorbable plug implants and method for bone tissue regeneration
(ZH) 用于骨组织再生的生物可吸收插销式植入体和方法
Abstract
(EN)
A bioabsorbable plug implant, suitable for bone tissue regeneration, comprising a first portion, and a second portion extending outwardly from the first portion, the first and second portions formed from expandable material. A method for bone tissue regeneration comprising the steps of: providing a bioabsorbable plug implant, wherein the implant comprises a first portion and a second portion extending outwardly from the first portion, the first and second portions formed from expandable material; inserting the second portion into a defect or gap of a bone, the first surface engaging the outside contour of the defect or gap; allowing the plug implant to contact body fluids, thereby expanding the size of the plug implant so that the plug fits into the defect or gap.

(ZH)

一种生物可吸收的插销式植入体,适于骨组织重建,其包含第一部分,和从第一部分向外延伸的第二部分,第一和第二部分是由膨胀材料制成的。骨骼组织重建的方法,包括步骤:提供生物可吸收的插销式植入体,其中植入体包括第一部分和从第一部分向外延伸的第二部分,第一部分和第二部分都是用可膨胀材料制成的;将第二部分插入到骨骼的缺陷或缝隙处,第一个表面接合了缺陷或缝隙的外轮廓;使插销植入与体液接触,因此插销植入的尺寸膨胀从而使这种插销与缺陷或缝隙相适合。
