摘要
[目的]介绍全膝关节置换术(total knee arthroplasty,TKA)多用途挡板设计与应用技术和初步临床结果.[方法]本多用途挡板结构包括相互连接的挡板、手柄与负压吸气器.挡板上设有圆形通透窗口、圆形通透窗口通道、矩形通透窗口.矩形通透窗口设置在挡板顶边的中部,圆形通透窗口设置在挡板的几何中心位置的一侧.手柄与挡板的下部连接;负压吸气器与手柄连接在挡板的下部,其前端开口延伸到挡板的中部形成吸气口,其后端开口连接外部负压抽气管道,将靠近挡板或附着在挡板表面上的血液、碎屑吸出.[结果]86例TKA患者术中应用多用途挡板,高效遮挡了飞溅的血液和碎骨渣,大大降低手术感染率,有效保护医护人员从而预防血源性职业暴露.86例患者均顺利完成手术,术后手术切口愈合良好.膝关节功能恢复良好,随访过程中未出现感染等严重并发症.[结论]本多用途挡板遮挡并吸附TKA手术过程中飞溅的血液和碎骨渣等污染物,降低了感染率,减少对医务人员的污染和伤害.
Abstract
[Objective]To introduce the design and preliminary application results of multi-purpose shield in total knee arthroplasty(TKA).[Methods]The multi-purpose shield was comprised with shield plate connected with each other,a handle and a negative pressure getter.The shield plate was provided with a circular transparent window,a circular transparent window channel and a rectangular transpar-ent window.The rectangular transparent window was arranged in the middle of the top edge of the baffle,while the circular transparent win-dow was arranged on one side of the geometric center of the shield.The handle was connected with the lower part of the shield,where a nega-tive pressure getter connected with the opening in the middle part of the shield plate to form an suction port.The rear end opening was con-nected to an external negative pressure suction pipe to suck out the blood and debris near the shield plate or attached to the surface of the plate.[Results]The multi-purpose shield was applied in TKA in 86 patients,which effectively shielded the spattered blood and bone frag-ments,greatly reduced the surgical infection rate,and effectively protected medical staff to prevent blood-borne occupational exposure.All 86 patients had the operation performed successfully,with surgical incision healed well.All of them got knee function recovered well,with no serious complications such as infection occurred during follow-up.[Conclusion]This multi-purpose shield blocks and absorbs the pollut-ants such as blood and bone fragments spattered during TKA,reduces the infection rate,and reduces the pollution and injury to medical staff.
