Technical Field

[0001] The present invention relates to the technical field of drainage equipment, and in particular to a drainage device for neurosurgery. Background Art

[0002] In the clinical treatment of many neurosurgical diseases, such as brain tumors, severe intracranial injuries, hypertensive cerebral hemorrhage, etc., neurosurgical drainage devices are needed. When performing neurosurgery on patients, due to the rich intracranial blood vessels, multi-level separation is required, which will cause a lot of exudation. This requires drainage of waste fluids such as blood in the exudate after the operation.

[0003] When draining a patient's brain fluid, doctors may need to extract and test local fluid in the brain to determine the patient's injury. However, most existing neurosurgical drainage devices drain the patient's brain fluid into a unified container, which makes it inconvenient for doctors to extract local fluid in the patient's brain.

[0009] Among them, the diversion structure also includes a supporting spring, the two ends of which are fixedly connected to the drainage tube and the movable sheet respectively. The supporting spring supports the movable sheet so that the movable sheet and the axis of the drainage tube form a certain angle to assist the accumulated fluid to enter the diversion tube.

[0010] Wherein, the diversion structure also includes a protective sleeve, which is sleeved on the outside of the resisting spring, and the two ends of the protective sleeve are respectively fixedly connected to the drainage hard tube and the movable sheet to protect the resisting spring.
