Drainage device capable of preventing blockage for neurosurgeons

Abstract

The invention provides a drainage device capable of preventing blockage for neurosurgeons, and relates to the technical field of neurosurgery. The drainage device capable of preventing blockage for the neurosurgeons comprises an air pressure adjusting assembly. According to the drainage device capable of preventing blockage for the neurosurgeon, hydrops can pass through a circular filter screen, and solid impurities can stay outside the circular filter screen, so that the effects of preventing solids in the hydrops in a cranial cavity from blocking the drainage device and improving the drainage quality are achieved. The total weight of a pressure disc can be controlled by setting the number of weights, so that the drainage speed is changed, and the effects of conveniently adjusting the drainage speed and reducing the surgical risk of a patient are achieved. When the suction force in a sealing box is too large, a protruding block moves downwards due to the suction force, and when the suction force in the sealing box is insufficient, the protruding block can block the interior of a ventilation groove again, so that the effects of avoiding the damage of patient cells caused by excessive suction and the failure of drainage caused by too small suction are achieved.

Description

technical field [0001] The invention relates to the technical field of neurosurgery, in particular to a drainage device for neurosurgeons to prevent blockage. Background technique [0002] Neurosurgery is based on the use of surgery as the main treatment method in surgery, and applies unique neurosurgery research methods to study the human nervous system. During neurosurgery, doctors often need to use drainage devices to drain the effusion in the patient's skull. For drainage, the existing drainage device drains the effusion in the cranial cavity, and the solid components in the effusion in the cranial cavity are likely to cause blockage inside the drainage tube, which affects the subsequent drainage effect, and the suction speed of the existing drainage device cannot be adjusted, which is inconvenient Rapid drainage of the effusion inside the cranial cavity as needed may increase the patient's surgical risk, and the suction of the existing drainage device cannot be controll...

[0002] Neurosurgery is based on the use of surgery as the main treatment method in surgery, and applies unique neurosurgery research methods to study the human nervous system. During neurosurgery, doctors often need to use drainage devices to drain the effusion in the patient's skull. For drainage, the existing drainage device drains the effusion in the cranial cavity, and the solid components in the effusion in the cranial cavity are likely to cause blockage inside the drainage tube, which affects the subsequent drainage effect, and the suction speed of the existing drainage device cannot be adjusted, which is inconvenient Rapid drainage of the effusion in the cranial cavity may increase the patient's surgical risk, and the suction of the existing drainage device cannot be controlled. When the suction is too large, it is easy to cause damage to the patient's cells and tissues, which is not conducive to the patient's recovery.

[0003] In order to solve the above problems, we provide a drainage device for neurosurgeons to prevent blockage, which can prevent solid blockage in the internal effusion of the cranium. The drainage device improves drainage quality and facilitates adjustment of drainage speed, reduces surgical risks for patients, and avoids suction during drainage. Excessive damage to the patient's cells is beneficial to the patient's recovery
