背景技术
临床上，慢性硬膜下血肿是指伤后三周以上颅内出血发生在硬脑膜下腔者，血肿增大后会产生占位效应，导致脑室和脑干受压，产生呕吐、意识障碍、头痛，颅内压增高为主，应及时进行CT确诊和果断手术干预。目前主要的治疗方法是颅骨钻孔闭式引流，医生通过在患者相应颅骨位置开孔，将硅胶引流管插入颅内硬膜下，对血肿液进行反复灌洗和引流，直至抽吸液清澈，以清除血肿液。
现有的灌洗引流技术主要采用硅胶管灌洗引流，但是，医生在整个手术过程中无法调整硅胶管吸引口的位置；此外，现有灌洗引流技术中，医生在手术过程中也无法实时监测硬膜下血肿液灌洗抽吸情况，医生只能凭手术经验去判断血肿液是否清除干净，这些都容易导致血肿液清除不彻底，增加二次手术风险。
