The dual-stage venous cannula is widely used but can obstruct the surgeon's view and interfere with operative procedures in the aortic root. We designed a new stainless steel sheath for a dual-stage venous cannula that enables the cannula to bend and maintain the appropriate angle for the surgical procedures. We suggest that operative procedures in the aortic root can be performed faster during safety cardiopulmonary bypass by use of a dual-stage venous cannula bent by application of this new sheath.
双腔静脉插管被广泛使用，但可能会遮挡外科医生的视野并干扰主动脉根部的手术操作。我们设计了一种用于双腔静脉插管的新型不锈钢护套，它能使插管弯曲并在手术过程中保持合适的角度。我们认为，在安全的体外循环期间，使用通过应用这种新型护套弯曲的双腔静脉插管，可以更快地进行主动脉根部的手术操作。
