Background

The double-cavity drainage tube is suitable for removing minimally invasive hematoma of cerebral hemorrhage and extracerebral drainage before, during or after craniocerebral surgery; extracerebral drainage of obstructive hydrocephalus and hydrocephalus of unknown cause; drainage of liquid matters of hematoma, abscess and cyst at various parts (subdural, epidural, intracerebral and the like) in the cranium.

Most of the commonly used drainage tubes in clinic are single cavities, doctors place the far end of the drainage tube into the position of a patient needing drainage in the cranium through craniotomy, the near end of the single cavity tube is drawn by a subcutaneous guide needle and is led out through an established subcutaneous channel to be connected with an in-vitro collection device, and therefore drainage is achieved. The single-cavity drainage catheter has the advantages that the catheter is not directly led out through a craniotomy part but led out through a subcutaneous passage, the probability of intracranial infection is greatly reduced, and the defect that single-channel drainage is easily blocked by hematoma to cause drainage failure is overcome.
