医疗设备创新医疗设备创新
手术技巧手术技巧

背景情况:

手术更换大动脉 (SAVR) 是一个常见的手术.
有效和安全的大动脉切除对于成功的SAVR至关重要.
当前的方法在废物管理方面可能存在局限性.

研究的目的:

为了验证一款用于大动脉切除的新型圆形刀片装置.
评估设备在切除大动脉的有效性.
为了评估设备在收集切除碎片的能力.

主要方法:

使用了一个单一尺寸的,外径22毫米的圆形刀片装置.
10名接受SAVR治疗的患者被选中进行本地主动脉切除.
患者的选择是基于手术前的大动脉直径评估.

主要成果:

该设备在90% (9/10) 的患者中实现了完整的大动脉切除.
在任何病人身上都没有观察到碎片栓塞.
所有患者都经历了无事件的术后过程.

结论:

使用圆形可折叠刀片切除大动脉是可行的.
该装置是切除的有效工具,即使是通过小切口.
原型有效切除门,而不会释放碎片.
