Development of a Retractor Holding Device to Reduce the Manpower in Total Hip Arthroplasty through Direct Anterior Approach

Direct anterior approach (DAA) for total hip arthroplasty (THA) is a minimally invasive technique. In this approach, two assistants are necessary. We developed a retractor holding device called “Spider arm” to replace an assistant in the contra-lateral side. In this study, we investigated the usefulness of Spider arm in THA through direct anterior approach. 20 hips were operated without Spider arm and 21 hips were operated with Spider arm. The surgery time and the blood loss were compared. The cup position and leg length discrepancy were measured on radiography. There was no statistical significance between two groups in all parameters. No clinical complications were reported. With Spider arm, DAA-THA could be performed by two surgeons without deterioration of the surgery time and blood loss. The accuracy of cup position and leg length discrepancy was not affected. Spider arm can contribute to reducing the manpower in DAA-THA.

PROTOS蜘蛛手机构传送臂漏油问题的解决

PROTOS卷接机组的烟支输送系统采用的蜘蛛手机构传送臂存在着漏油问题,漏出的润滑油会进入负压通道,污染烟支。通过对蜘蛛手机构传送臂结构及漏油原因分析,提出改进方案如下:在传送臂中的油腔和负压通道之间增加一个隔离空腔,并在骨架油封前增加螺旋密封结构。改进后的蜘蛛手机构使油腔和负压通道完全隔离,减小了骨架油封两侧的压差,降低了发生泄漏的可能性,从根本上解决了蜘蛛手机构传送臂漏油的问题。

ZJ17卷烟机组SE蜘蛛手循环供油润滑改造

ZJ17卷烟机组SE部分蜘蛛手传动机构长时间高速运转后蜘蛛手臂的骨架油封容易老化产生漏油,导致蜘蛛手臂吸爪掉烟和产生油烟现象。通过对蜘蛛手臂漏油分析及根据蜘蛛手传动机构的特殊结构,决定对蜘蛛手传动机构的润滑方式进行改造。将原有的油浴润滑改造成循环供油润滑。通过改造,降低了蜘蛛手传动齿轮箱内的油温,延长了油封的使用寿命,减少了漏油现象,提高了蜘蛛手传动机构的使用寿命,从而降低了维修的劳动强度,提高了设备的作业率,而且降低了生产成本。
