脑室枕角穿刺定位器
本技术涉及医疗器械
,尤其涉及一种脑室枕角穿刺定位器。
技术介绍
脑积水是神经外科常见疾病之一,脑室腹腔分流术是脑积水的标准治疗方法。脑室端导管的植入有经额角、经三角区和经枕角路入三种。经枕角路入的优点是导管完全位于侧脑室体部,远期堵管率低。穿刺过程如下:患者取仰卧位,头偏向一侧,穿刺点为枕外隆突上6厘米,旁开3厘米,对准同侧眉弓上1厘米穿刺,穿刺深度7-9厘米,即进入侧脑室体部,然而枕角穿刺侧脑室技术要求高,易发生导管位置不准确,损伤脑组织,目前急需研发一种增加侧脑室经枕角穿刺准确性的器械。上述以往的穿刺过程中,所有的技术都很量化,唯一不能量化的就是穿刺方向:穿刺时针尖指向同侧眉弓中点上1厘米,这个方向术者不能直视,只能想象,其精度很难得到保证,如方向有误,就会导致穿刺失败,造成引流管位置不准确,或误伤重要的脑深部结构,甚至造成出血,产生严重并发症。因此,开发研究一种结构简单,且能够准确定位的穿刺辅助器械是本领域急需解决的问题。
