一種連續纖維增強水凝膠柔性植入支架及其原位定制化成型方法和應用

本發明涉及(ji)生物復合(he)材(cai)料,尤其涉及(ji)一(yi)種連續纖維增強水凝膠(jiao)柔性植入(ru)支架及(ji)其原位定制(zhi)化成(cheng)型方法(fa)和應用。


背景技術:

1、水凝(ning)(ning)膠是一種(zhong)柔(rou)軟、濕(shi)潤(run)且具(ju)有(you)生(sheng)物相(xiang)容性(xing)(xing)(xing)的(de)凝(ning)(ning)膠結構,而(er)(er)纖維則具(ju)有(you)較(jiao)高的(de)力(li)學性(xing)(xing)(xing)能(neng)(neng)和穩(wen)定性(xing)(xing)(xing)。將(jiang)兩者復合構建的(de)纖維增(zeng)強水凝(ning)(ning)膠可兼具(ju)纖維高強度(du)和水凝(ning)(ning)膠濕(shi)滑柔(rou)韌特(te)性(xing)(xing)(xing),形(xing)成力(li)學性(xing)(xing)(xing)能(neng)(neng)優(you)異且質地(di)柔(rou)軟的(de)功能(neng)(neng)性(xing)(xing)(xing)復合材(cai)料(liao),因而(er)(er)具(ju)有(you)廣泛(fan)的(de)應用(yong)(yong)前景(jing)。例如,在醫學領(ling)域(yu),纖維增(zeng)強水凝(ning)(ning)膠可用(yong)(yong)于(yu)組(zu)織(zhi)工程和藥物釋放系統;在生(sheng)物工程領(ling)域(yu),可用(yong)(yong)于(yu)制(zhi)備生(sheng)物材(cai)料(liao)和人工組(zu)織(zhi);在環境(jing)保護領(ling)域(yu),可用(yong)(yong)于(yu)水處理和污染控制(zhi)等(deng)方面(mian)。

2、柔性(xing)(xing)(xing)植(zhi)入支(zhi)架(jia)(jia)通常由生(sheng)物相容(rong)性(xing)(xing)(xing)高分(fen)子(zi)水凝膠材料制成(cheng),用(yong)于(yu)支(zhi)撐、修(xiu)復或替代(dai)人體受損組(zu)織,起到恢復其(qi)生(sheng)理功能的作用(yong),可應用(yong)于(yu)皮膚創面(mian)修(xiu)復、軟骨(gu)修(xiu)復、腹腔(qiang)(qiang)補片(pian)(pian)、盆腔(qiang)(qiang)補片(pian)(pian)等。水凝膠的力學性(xing)(xing)(xing)能和(he)穩定(ding)性(xing)(xing)(xing)主(zhu)要依(yi)賴其(qi)交聯(lian)密度,然而這(zhe)通常難以滿足植(zhi)入支(zhi)架(jia)(jia)的性(xing)(xing)(xing)能需(xu)求(qiu),因此使用(yong)纖維增(zeng)強是提(ti)升(sheng)柔性(xing)(xing)(xing)植(zhi)入支(zhi)架(jia)(jia)結(jie)構(gou)性(xing)(xing)(xing)能的有(you)效途徑。與此同時(shi),植(zhi)入支(zhi)架(jia)(jia)的個(ge)性(xing)(xing)(xing)化定(ding)制又可進一步提(ti)升(sheng)支(zhi)架(jia)(jia)在植(zhi)入區域與周圍組(zu)織形貌(mao)結(jie)構(gou)的匹配程度,提(ti)升(sheng)植(zhi)入穩定(ding)性(xing)(xing)(xing)與組(zu)織適(shi)配性(xing)(xing)(xing)。

3、在(zai)個性化纖維(wei)增(zeng)(zeng)強水(shui)(shui)(shui)凝(ning)膠植入物(wu)方(fang)面,中國專利(li)cn116478423a、cn116650727a公開了使用(yong)碳纖維(wei)、絲(si)素蛋白纖維(wei)等(deng)(deng)纖維(wei)材(cai)(cai)料(liao)與(yu)水(shui)(shui)(shui)凝(ning)膠復(fu)合,構建(jian)短(duan)纖維(wei)增(zeng)(zeng)強水(shui)(shui)(shui)凝(ning)膠復(fu)合材(cai)(cai)料(liao),可做柔(rou)性材(cai)(cai)料(liao)用(yong)于智能(neng)穿戴傳感器以及組織(zhi)工程支架。然而,由于植入物(wu)支架采(cai)用(yong)纖維(wei)為(wei)短(duan)纖維(wei)形態,因(yin)纖維(wei)長度有限,結構性能(neng)仍然不足,無法(fa)滿足人體組織(zhi)的(de)正常生理功(gong)能(neng);中國專利(li)cn109675115a、cn116983469a提(ti)出使用(yong)納米纖維(wei)等(deng)(deng)連續纖維(wei)增(zeng)(zeng)強水(shui)(shui)(shui)凝(ning)膠復(fu)合材(cai)(cai)料(liao),用(yong)于人工血(xue)管、骨組織(zhi)修復(fu)等(deng)(deng)領域,有效提(ti)升水(shui)(shui)(shui)凝(ning)膠材(cai)(cai)料(liao)的(de)力(li)學性能(neng)與(yu)穩定性。但(dan)是仍存在(zai)力(li)學強度不佳的(de)問題。

技術總結
本發明提供了一種連續纖維增強水凝膠柔性植入支架及其原位定制化成型方法和應用,屬于生物復合材料技術領域。本發明以高性能連續纖維為結構纖維、連續化水凝膠前驅體纖維為基體,復合構建合股纖維束結構,通過柔性導向三維仿形織造成型技術,依據目標組織的結構與形貌特征進行三維仿生編織成型,形成復合纖維預成型體;最終,利用復合纖維中水凝膠前驅體纖維的吸水溶脹與協同交聯,實現預成型體中前驅體纖維向水凝膠基體的轉變。
