Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a ventricular drainage tube clamping device for neurosurgery.
Background
When the intracranial volume is increased due to various pathogenic factors, the pressure of cerebrospinal fluid measured by lumbar puncture in lateral position exceeds 1.92kpa, namely intracranial pressure is increased, if a series of clinical manifestations such as headache, vomit, vision disorder, papillary edema and the like appear, the intracranial pressure is called intracranial pressure increasing syndrome, and according to Monroe-kellie principle, except that blood vessels are communicated with the outside of the cranium, the cranial cavity can be basically regarded as a non-telescopic container, and the total volume of the spinal cavity is unchanged.
The intracranial consists of three contents, namely brain tissue, blood and cerebrospinal fluid, the volumes of which cannot be compressed, but can be mutually compensated within a certain range, the total volume of the cranial cavity is unchanged, and the volumes of the cranial contents are variable under different physiological and pathological conditions, so that the contradiction between the two is formed, accurate physiological adjustment is required to ensure the balance between the two, and if the volume of one part of the cranial contents is increased, the compensatory reduction of the other part is necessarily caused to adapt, which is the basic principle for maintaining the normal intracranial pressure, and if the mechanism is damaged beyond a certain limit, the intracranial pressure is increased.
Of the three contents, the brain tissue volume is the largest, but the effect on volume compensation is the smallest, normal intracranial pressure is maintained mainly by compressing cerebrospinal fluid and cerebral blood flow, compensation can be obtained by increasing the volume of the content of the cranial cavity by 5%, obvious intracranial pressure increase occurs when the volume of the content of the cranial cavity exceeds 8-10%, cerebral edema, cerebral fluid volume or cerebral blood flow increase, intracranial space occupying lesions and the like caused by various reasons can be caused by the increase of the content of the cranial cavity, such as normal content of the cranial cavity, intracranial pressure increase can also be caused when the volume of the cranial cavity is reduced due to narrow cranium deformity, cranium undercut, skull bone tumor, malformation osteomyelitis or depressed fracture of the skull, and the like, and on clinical medical treatment means, the intracranial pressure is usually released directly, and a drainage tube is needed for releasing the intracranial pressure.
At present, when a drainage tube is fixed for a patient needing ventricular drainage, an adhesive tape is usually used for being stuck on the scalp, and the head is wrapped by gauze so as to prevent the drainage tube from falling off, but the following problems exist in the method:
1. when the drainage part is required to be operated, the operation can be performed after the gauze is completely disassembled, the stability of the drainage tube is inevitably affected in the process of disassembling the gauze, and if the drainage tube is pulled, great potential safety hazard is brought to the drainage of a ventricle patient;
2. when the gauze is used for wrapping, the head and the drainage part of the patient cannot be ventilated;
3. the clamping device of some current drainage tubes usually directly exerts clamping force to the drainage tube, but the clamping force is too big can be with the flat jam of drainage tube clamp, and the clamping force has little can't carry out effectual fixed to the drainage tube.
Accordingly, the present invention provides a ventricular drainage tube clamping device for neurosurgery to solve the above-mentioned problems.
