Gravity-fed irrigation systems in arthroscopic surgery are safe and cheap, but visualization can be impaired by fluctuations in in-flow pressure, which leads to bleeding and temporary disruption of surgery. We describe a gravity-fed irrigation system using differential hydrostatic pressures in sequentially arranged irrigation bags that can be independently raised and lowered. This technique maintains a relatively steady flow and intra-articular pressure, thereby improving the quality of irrigation without having to resort to the more expensive pressure infusion systems, and minimizing the need for surgery under tourniquet.
关节镜手术中的重力灌注系统安全且成本低廉，但入流压力的波动会影响视野，导致出血并暂时中断手术。我们描述了一种利用依次排列的灌注袋中的不同静水压力的重力灌注系统，这些灌注袋可以独立升降。该技术可维持相对稳定的流量和关节内压力，从而提高灌注质量，而无需使用更昂贵的压力灌注系统，并最大限度地减少使用止血带进行手术的需求。
