The utility model relates to the field of medical surgical instruments, in particular to a lateral ventricle drainage tube, which comprises a drainage tube and a drainage hole. The drainage hole is arranged at the front end of the drainage tube, the ventricle end of the drainage tube is spherical, the middle part is a drainage hole, the diameter of the drainage hole is less than the drainage tube, and the drainage tube is 6 cm away from the head of the bone hole. An elastic steel ring of the same diameter is arranged in the flow tube every 2 mm, and at least one developing flexible metal wire is added to the wall of the drainage tube longitudinally. The developing flexible metal wire extends to the ventricular end of the drainage tube and forms a ring at the drainage hole. The device has reasonable structure and convenient operation, and avoids the invalid end about 8 mm long behind the former drainage tube head. And it is conducive to drainage, reducing the narrowing of the drainage tube cavity at the bend of the drainage tube, ensuring the smooth drainage, strengthening the tensile strength of the drainage tube, reducing the incidence of tube breakage.
【技术实现步骤摘要】
一种侧脑室引流管
本技术涉及医疗手术器械领域,特别涉及一种侧脑室引流管。
技术介绍
侧脑室出血起病急剧、病死率高。目前侧脑室出血治疗方法有以下几种1:侧脑室引流2:脑室镜治疗3:开颅手术治疗。其中侧脑室引流术由于操作简单,疗效较好被广泛采用。但是目前的侧脑室引流管的脑室端存在一定的缺点,现说明如下:1:侧脑室引流管的脑室端的开口开在引流管头端后方的侧壁上,这导致引流管头端后方约8mm长的无效引流管。为了让开口达到侧脑室额角,只能加大脑室穿刺的深度。如有不慎,可能将引流管的脑室端置入过深,导致不利后果。此外,当侧脑室引流术后,急性梗阻脑积水导致的扩大的脑室,因为脑脊液引流至体外而逐渐恢复至正常大小。这会导致部分侧脑室引流管的脑室头端从脑室额角脱出。而一旦头端从脑室额角脱出后,因开在引流管头端后方的侧壁上的开口被脑组织遮挡,脑脊液就无法排出,脑室内压力就会逐渐增高,而压力经脑组织-引流管隧道作用于在引流管头端,逐渐将引流管推离额角。最终导致侧脑室引流管远离额角,失去引流作用。2:侧脑室引流管出骨孔经皮下隧道至皮外,一出骨孔,大部分侧脑室引流管转弯角度超过80度,这导致侧脑室引流管管腔变窄,在引流液粘稠的情况下,这极有可能导致引流不畅。
