Description

Technical Field

[0001] The present invention relates to the field of medical technology, and particularly relates to a drainage control device and method for neurosurgery. Background Art

[0002] In neurosurgery, postoperative drainage is a key link in removing inflammatory exudates at the affected area, directly affecting the patient's prognosis. The traditional drainage device has the following technical problems to be solved urgently: Most existing drainage tubes adopt a cylindrical single-chamber structure, and the drainage holes are easily blocked by brain tissue debris or blood clots, resulting in interrupted drainage. In addition, the contact area between the drainage tube and the lesion area is limited, and it is impossible to efficiently collect the effusion, prolonging the recovery period. The drainage tube lacks reliable support in the body, and it is easy to shift or prolapse when the patient moves, affecting the drainage effect. Some devices are assisted by external fixing parts, but the operation is complex and it is easy to cause skin compression injury. The existing devices only achieve one-way drainage and cannot take into account both drainage and protection of the affected area. The drainage tube inevitably contacts the surrounding normal tissues and lacks the function of actively expanding or isolating the lesion area.

[0003] In view of the above problems, in order to achieve drainage efficiency and safety, therefore, the present invention proposes a drainage control device and method for neurosurgery. Summary of the Invention
