Technical Field
The invention relates to the technical field of neurosurgery, in particular to a drilling and pipe placing sealing guide device.
Background
Chronic subdural hematoma is a common neurosurgical disease in clinic, and is better in the elderly population over 50 years old, and the incidence rate of the chronic subdural hematoma accounts for about 10% of intracranial hematoma. The current treatment for chronic subdural hematoma still uses drill drainage as the main treatment measure. However, the catheter is not ideal in position and air enters into the cranial cavity due to restlessness, blood swelling and too fast drainage of the patient, so that the brain tissue rebounds badly or the condition is aggravated after the operation.
The Chinese patent application: CN201692472U discloses a chronic subdural hematoma drainage tube, which is provided with a tube body and is characterized in that the front end part of the tube body is provided with drainage holes which are arc-shaped and are arranged on two side surfaces of the arc-shaped tube body at the front end part of the tube body. The device can reduce the angulation of the drainage tube and the inner plate of the skull, and avoids the drainage tube from being inserted into gradually swelled brain tissue after operation. However, the device is hard and tough, and is easy to be inserted too deep in the operation, which causes brain tissue damage, damage to cortical bridgeveins and intracranial hemorrhage, and when the drainage tube is placed, arachnoid is also easy to be damaged, and no device capable of isolating gas from entering into cranial cavity is arranged, so that the intracranial hemorrhage or the skull is often caused due to pressure difference, and the treatment of patients is affected.
The Chinese patent application: CN202538127U discloses a chronic subdural hematoma drainage tube guide needle, which comprises an integral metal round bar, wherein the front end of the metal round bar is bent to form an elbow, and the rear end of the metal round bar is provided with a lifting lug. The device mainly makes things convenient for the drainage tube to put into subdural hematoma chamber, prevents to put into subdural drainage tube and stabs cerebral cortex, but the device is too simple single, can not put into subdural hematoma intracavity of putting into of the quick safety of pipe, and the device can not adjust the pipe direction of putting in addition, also does not have the device that can the outside gas entering skull chamber in addition, consequently is unfavorable for using widely.
Therefore, in summary, there is a need for a novel drilling and tube-placing closed guiding device which is simple in operation, capable of drilling and tube-placing, rapidly draining hematoma, adjusting tube-placing direction and preventing gas from entering cranial cavity due to pressure difference, and no report is found about the novel drilling and tube-placing closed guiding device.
