Retraction of the sigmoid sinus and the dura requires a strong instrument. The instruments currently available allow only a limited degree of freedom due to their lack of mobility and versatility. A new sigmoid sinus retractor (Micro-France/Instrumentarium) was designed to facilitate the surgeon's task by offering the following advantages: Three-dimensional mobility of the blade: lateral, rotatory and longitudinal Safe positioning of the retractor by three sets of sharp teeth Fixation of the blade by a single screw Strong retraction without giving way.
乙状窦和硬脑膜的牵开需要一种坚固的器械。目前可用的器械由于缺乏灵活性和多功能性，仅允许有限程度的活动自由度。一种新型乙状窦牵开器（Micro-France/Instrumentarium）被设计出来，通过提供以下优点来方便外科医生的操作：刀片的三维活动度：侧向、旋转和纵向；通过三组尖齿实现牵开器的安全定位；通过单个螺钉固定刀片；强力牵开且不会松动。
