Description

灌装导管
技术领域
本实用新型涉及一种灌装导管，属于医疗器械领域，适用于骨科手术中骨水泥的植入。 
背景技术
骨质疏松是常见病，容易引发压缩性骨折等疾病，给患者带来痛苦，影响人们的日常生活，治疗骨质疏松传统的治疗方法有卧床休息、药物镇痛、外固定支具等这些方法极易引起其他恶性循环给患者带来更大伤害。目前骨科手术治疗的方法多采用螺钉固定、在钉道填充骨屑、注入骨水泥等方法进行治疗，这些方法稳定性好、创口小、安全可靠，目前采用注射骨水泥的形式多样，但是手术过程复杂，成本较高。 
发明内容
本实用新型正是在保留现有技术优点的前提下，提供一种在手术过程中具有结构简单、操作方便的灌装导管。 
本实用新型的技术方案如下： 
灌装导管由导管(1)、导针(2)、手轮(3)组成。其特征在于：导管(1)中心台阶通孔结构，外表面为台阶杆状，左端有螺纹，右端有外六方、环形凹槽、螺纹；导针(2)为光杆结构，左端头部为球形；手轮(3)为台阶状，中心通孔，右端有滚花，且头部为球形。 
导管(1)：中心台阶通孔，引导骨水泥注入，左端螺纹与中空螺钉连接，右端螺纹与医用注射器连接，注入骨水泥，密封性能好，导管(1)可设计为多种规格，供手术选择。 
导针(2)：与手轮(3)连接，可选择性的注入骨水泥，也可将导管(1)中的剩余骨水泥推入，提高骨密度，导针(2)可设计为多种规格，供手术选择。 
本实用新型可配合中空螺钉注射骨水泥。 
通过术前CT或X光等诊断病症，实施手术：确定手术位置和骨水泥量，确定灌装导管的尺寸及规格。首先确定中空螺钉植入的深度、方位和数量，实施钻孔，植入中空螺钉，添加骨水泥，连接灌装导管及医用注射器，注入骨水泥至手术要求。 
本实用新型适用于骨科手术中骨水泥的注入，灌装导管结构简单、操作方便、安全可靠、成本较低，适宜于骨科临床推广应用。 
附图说明
图1为本实用新型的灌装导管结构图。 
图2为本实用新型的导管(1)结构图。 
图3为本实用新型的导针(2)结构图。 
图4为本实用新型的手轮(3)主视图。 
具体实施方式
下面结合附图对本实用新型作进一步说明。 
灌装导管由导管(1)、导针(2)、手轮(3)组成。其特征在于：导管(1)中心台阶通孔结构，外表面为台阶杆状，左端有螺纹，右端有外六方、环形凹槽、螺纹；导针(2)为光杆结构，左端头部为球形；手轮(3)为台阶状，中心通孔，右端有滚花，且头部为球形。首先确定中空螺钉植入的深度、方位和数量，实施钻孔，植入中空螺钉，添加骨水泥，连接灌装导管及医用注射器，注入骨水泥至手术要求。
