Description

医用固定器械及其制造方法 技术领域
本发明涉及医疗器械领域，尤其涉及一种医用固定器械及其制造方法。
背景技术
韧带、肌腱、肩琐或其他软组织从骨完全或部分分离是一种常见损伤，在运动员和老年人中尤为常见。当遭受暴力，产生非生理性活动，韧带被牵拉而超过其耐受力时，即会发生损伤，甚至发生组织分离。尤其是当组织从其相关联的骨完全分离时，通常需要外科介入治疗。
通过带缝线的锚钉使生物组织和骨骼相互固定是常用的外科手术治疗方式之一。手术后锚钉在骨组织可能发生松动，硬质锚钉的尖端或螺纹会划伤人体组织，造成进一步伤害。
有必要开发一种新型医用固定器械及其制造方法，以改善现有技术中存在的上述部分问题。
