Abstract
生物性髓内骨螺钉涉及骨外科处理中的接骨器具。用健康新鲜之同种或异种骨骼机械加工成一端呈螺纹状，一端呈圆柱状的规则体，经特殊处理后灭菌备用。本构件有一定的机械强度，可用于四肢长骨(包括手、足部诸长骨如掌指骨、跖趾骨)等的横形、短斜和轻度粉碎骨折的支撑固定和骨病畸形的修复矫正。本接骨器具无毒、无致癌性与过敏反应，与人体组织相容性好，可缓慢吸收融合，取材容易，加工储存简便，是一种理想的骨折内固定器。
Description
技术领域：本实用新型涉及一种医疗用器件，属于骨科内固定器。
技术背景：治疗手足长骨(如掌指骨、跖趾骨)骨折，常用金属材料制成的内固定物，如微型钢板、克氏针、斯氏钉等进行固定。然而，这些金属内固定物一般均需二次手术取出；克氏针、斯氏钉留置体外也增加了病人的感染机会。治疗四肢长骨骨折，传统所用的金属髓内钉固定，也存在需二次手术取出的弊端。
发明内容：本实用新型的目的，是要提供一种可吸收融合，能被自身组织替代，不需二次手术取出的、稳定可靠的髓内固定物。
本实用新型涉及一种可吸收性内固定构件，为去蛋白、去脂肪和灭菌处理后的骨骼组织，其特征在于，一端呈螺纹状，一端呈圆柱状。
附图说明：附图为本实用新型的结构示意图。图中1为螺纹，2为圆柱。
具体实施方式：用普通丝锥在长骨一端髓腔内攻丝后，拧入本实用新型(1在此端固定)，待2接近尾部时，复位骨折(复位前需将另一端长骨髓腔用小一号丝锥攻丝)，再用夹持钳反向旋转本实用新型，使2伸入另一端长骨髓腔固定。
应该指出的是，包括同种和异种骨骼加工成的挤压骨螺钉都应落在本实用新型的保护范围之内。
本实用新型采用同种或异种骨骼作材料，无免疫抗原性，其机械强度大于成人股骨皮质骨，除适合于手足长骨(如掌指骨、跖趾骨)骨折的支撑固定、也适合于尺桡骨、肱骨、胫骨、股骨等横形、短斜和轻度粉碎骨折的支撑固定以及骨病畸形的修复矫正。本实用新型取材方便，质量安全可靠，易于推广应用。以生物材料取代金属材料，符合人体生理需要。
