The utility model relates to a cranial cavity drainage tube after craniotomy, which comprises a drainage tube body, and the drainage tube body comprises a successively connected intracranial segment, a transitional segment and an extracranial segment. The inner diameter of the intracranial segment, a transitional segment and an extracranial segment are identical, and the outer diameter of the transitional segment is larger than that of the intracranial segment and the extracranial segment, thus forming a circular protrusion; the outer wall of the circular protrusion is flat with the outer wall of the intracranial segment and the extracranial segment, respectively. Sliding transition connection; the outer wall of the extracranial segment at one end of the transition segment is also equipped with a fixed ring matched with the surgical thread, thus firmly fixing the drainage tube body to the patient's head. The designed drainage tube for craniotomy increases the wall thickness of the deformed part of the traditional drainage tube. Without affecting the placement of the wound, it strengthens the compressive performance of the drainage tube, keeps the drainage tube smooth during the drainage process, ensures that the drainage material can continue to flow through, and is fixed firmly and not easy to loosen, and avoids the drag caused by the adjustment of the patient's posture. Intracranial drainage tube, or even out of the wound.

开颅手术术后颅腔引流管
本技术涉及临床医疗中开颅手术后的引流管,具体地指一种开颅手术术后颅腔引流管。
技术介绍
临床上在开颅手术后,所采用的颅腔引流管多为管径均匀的长橡胶管,引流管一端置于颅腔内,另一端穿过颅骨及皮肤与体外引流袋相连,根据开颅术中及术后情况需在管子颅内段对应位置剪出侧孔加强引流效果,引流管的颅外段用手术丝线栓接固定于颅外头皮表面。目前开颅术后所采用的颅腔引流管存在以下缺陷:1、引流管管腔抗压性能不足:引流管需要穿过皮肤,而根据伤口部位不同,患者活动头部时有些体位会将引流管压在头下,由于传统引流管一体成型,而伸入颅内的管壁材质不能太硬,否则会伤到颅内组织,导致引流管管腔抗压性能不足。患者头部不时活动,颅外部分即使压闭也是暂时的,临床上最常见的导致并发症的引流不畅常见于引流管穿越皮肤的部分,即颅外段尤其是引流管伸出头皮处容易被压瘪,该处皮肤张力大,若这部分被压闭可导致持续性引流不畅,积液积血残留量内,使得颅内压升高,重者危及患者生命。因此,既不能使用质硬材料又要求引流管跨皮肤段一定的抗压性能。2、引流管固定的稳固性不足:开颅患者多烦躁多动,易使得引流管 ...
