技术领域
本公开涉及医疗器械的技术领域，尤其是涉及一种引流导管和灌洗引流装置。
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。
发明内容
本公开的目的在于提供一种引流导管和灌洗引流装置，以至少缓解现有灌洗引流技术中，医生无法调整硅胶管吸引口的位置导致的血肿液清除不彻底的问题。
本公开实施方式采用如下技术方案：

本公开实施方式提供的引流导管能够实现如下有益效果：
本公开实施方式提供的引流导管中，远端软管和近端连接管之间通过管接头实现软管和硬管的连接，并且通过各管上设置的过液通道和至少一个转向丝通道实现使引流管能够配合转向丝工作的功能，具体地，装配时，在转向丝通道内部穿入转向丝，然后， 使转向丝的远端连接于远端软管的远端，通过向近端方向牵拉转向丝的方式，使远端软管的远端弯折转向，进而改变远端软管上过液通道的引流入口的位置，从而实现多角度引流，以帮助医生清除血肿液，降低二次手术风险；或者，在转向丝通道内部穿入转向丝，然后，将可转向头装配在远端软管的远端，使转向丝的远端固定于可转向头，可转向头上或者远端软管的远端管壁上设引流孔，通过向近端方向牵拉转向丝的方式，使可转向头弯折转向，进而改变引流孔的位置，从而实现多角度引流，以帮助医生清除血肿液，降低二次手术风险。
