The utility model relates to a card compound for repairing skull defect after minimally invasive skull base surgery, which comprises a card compound body and a clamping part arranged on the card compound body, the card compound body is an arched elliptical thin plate with physiological curvature, and the clamping part is arranged at the center of the convex surface of the card composite body. The card compound provided by the utility model is made of PEEK macromolecule material and processed by mechanical or injection moulding, and is designed to match the shape of the skull defect with the surrounding structure, which not only keeps a certain strength, but also prevents the patch from falling off due to the sudden increase of intracranial pressure after operation, but also maintains a certain elasticity. Make placing easy to shape operation. The thin layer design can fix the edge directly between the dura mater and the skull without the aid of other fixing devices. To avoid complications such as cerebrospinal fluid leakage, herniation of brain tissue and eye pulsation after operation.

技术介绍
随着显微手术技术的发展,越来越多的神经外科及耳鼻喉科的位于前、中颅底附近的肿瘤及病变,如前颅底各部脑膜瘤、鞍区垂体瘤、颅咽管瘤、各种囊肿及脑脊液漏等病变,在显微镜或神经内镜的辅助下,通过不损面容的、创伤较小的、途径较短的,且通过自然腔道的经口、鼻、筛、蝶或锁孔经额来切除病灶,除了缩短手术时间,而且大大提高了手术效果,正被广泛的开展。通常的经蝶途径行鞍区垂体瘤、颅咽管瘤等病灶的切除后,常留有鞍底的颅骨缺损;经筛的前颅底脑膜瘤切除或脑脊液漏修补时常留有筛板的颅骨缺损。绝大多数手术结束前是以软质材料来封堵此颅骨缺损的,包括使用明胶海绵、止血纱布、脂肪、肌肉、筋膜、粘膜瓣、人工脑膜、生物或化学胶等材料,上述组织随时间推移都有被人体吸收的可能;因无有力的支架支撑,常在某次突然的颅内压增高时被冲开而导致脑脊液外漏或并发感染。少数手术结束前以硬质材料来封堵此骨缺损,包括骨性鼻中隔、钛网、骨水泥、髂骨修剪片等材料。骨性鼻中隔缺损术后易致鼻梁下塌或鼻中隔穿孔,钛网难以修剪且易刺伤周围组织,骨水泥塑形差且占体积,取髂骨创伤大。所以在前、中颅底微创手术量急速增加的今天,这一关键技术步骤仍无有效措施。中国专利技术专利201710153409.0公开了一种解剖重建颅骨补片,由可降解生物硬性材料通过3D打印制成,虽然该颅骨补片可以进行水解降解,并通过自然途径被去除,且可以直接根据患者缺损部位成型制作,但是随时间推移会被人体吸收,吸收后容易脱落;因无有力的支架 ...
